Symbols can be accessed from the pull down menu Electrical or from the toolbar Schematic Diagrams

Control Ladder Diagram

The function generates horizontal control ladders and reference line numbers. The defaults are for a horizontal control ladder on an A1 drawing sheet.

Initiate the command from pull down menu Electrical > Add Control Ladder or from the toolbar Schematic Diagrams - Control ladder

Files Created: Elecsettings.ini or Elecsettings_Clientname.ini

Current Settings

If a control ladder exists in the current drawing, its defaults will be indicated in this area.

Configure

If a control ladder does not exist the settings will be retrieved from the settings file indicated below the configuration button. Selecting the configuration button will allow the user to change these settings. If a control ladder exists in the current drawing, the settings will be displayed and indicated below the configuration button as Current drawing settings. The settings shown will be used to create the control ladder. Making changes without saving the settings will be indicated as Local Drawing Settings.

Save

Selecting the save button will save the current drawing settings shown to the configuration file to be used as the default for new drawings.

Adjust

Selecting the adjust button will adjust the x coordinate and the ladder offset distance. The AutoCAD background grid will be set to the aspect ratio of the control ladder spacing. To make sure the next control ladder is aligned with the background grid, the adjusted insertion point and current settings must be saved. Select the save buttons in sections Current Settings and Grid Insertion Point. If the new calculated insertion point is to be kept as the default, the save button located in section Grid Insertion Point must be be selected.

Grid Insertion point

Either type in the X and Y coordinates of the grid insertion point or select the Pick button and pick a point in the drawing. The X and Y values will be rounded off to the nearest multiple of the snap unit set from Configure - Snap Unit (Grid Modulus). If the point is for the first left hand control ladder, selecting the Save button will make the current value the default insertion point for all new drawings. The X coordinate is automatically incremented for successive control ladders on the same drawing by the value contained in the Configure - Distance Between Ladders. When a horizontal reference line is created with a control ladder the grid will be set to an aspect ratio equal to a section (1/10 the width of the ladder width) and half the rung spacing. This will give an indication of symbol insertion so wire numbers can be determined. Inserting symbols midway between the vertical grid dots will allow wire numbers to be used from the horizontal reference grid.

X Contains the X coordinate of the insertion point which can be entered manually
Y Contains the Y coordinate of the insertion point which can be entered manually
Pick The user has the option to select the insertion point. Their X and Y values will rounded of to the nearest snap
unit and entered into their respective edit boxes.
Save This will save the current X and Y values shown in the edit boxes and will be used as the default insertion point
for the first control ladder on new drawings.

Control Ladder Setup

Sheet No

If cross referencing between multiple drawings is required, enter a sheet number from one to nine. If no number is required, enter zero.

First Line No

Enter the first ladder rung number. If a sheet number is greater than zreo the line numbers 1 to 9 will be padded out with a ‘0' which would read 01 02 ….08 09 10…

Sheet Number First line number Reference line numbers
0 or Blank 1 1, 2, 3...
0 or Blank 01 01, 02, 03...
1 1 or 01 101, 102, 103....
01 1 or 01 0101, 0102, 0103....
No of Ladder Rungs

Enter the number of ladder rungs or select Pick No of Ladder Rungs button and pick the length of the control ladder. The number of rungs will be calculated by dividing the length by the Configure - Ladder Rung Spacing. The maximum number of rungs per drawing sheet for each Sheet No is 99. If more than 99 lines are required, increment the sheet number, and sett the first line number back to 01.

No of Power Circuit Rungs

For a horizontal DOL power circuit leave six spare rungs at the top of the control ladder. For a vertical DOL power
circuit, disable the Spare rungs check box and offset the control ladder by 90 units from the option Configure - Ladder
Offset from Ref Line.
Disable the Spare rungs check box for subsequent control ladders as only one power circuit is required for each
drawing.
Up to six (6) reference lines can be drawn on a single drawing for automatic cross referencing.

Horizontal Reference line

If the check box is enabled a horizontal grid reference line will be created. The line will be number from 0 to 9 and spaced evenly the width of the control ladder.

Vertical Reference line

If the check box is enabled a vertical grid reference line will be created.

Control Ladder

If the check box is enabled a control ladder will be created with the current settings. The control ladder is created on layer CONTROL_LADDER and with a pen width of 0.35

Select the Configuration button and make settings as required. If the current settings are to be the defaults for all control ladders, select the save button otherwise the settings will only be used for the current control ladder. If the settings are only required for a one unique control ladder eg. the ladder width is smaller than normal do not save the settings, select the Ok button.

Control Ladder Configuration

Settings

Snap Unit (Grid Modulus)

The snap unit is used to round off the Grid Insertion Point, Ladder Rung Spacing, Offset, Ladder width and Distance between ladders so that it will comply with the snap setting eg it the snap settings is set to 2.5 then all variables must be in multiples of 2.5.

Ladder Rung Spacing This is the horizontal spacing between ladder rungs which are drawn between the power rails. If Relay coils are to be used in the control circuit, then the minimum spacing should be 15 unless the relay coils are to be offset. In general the minimum spacing should be not less than 10.

Ladder Offset This is the distance the left hand power rail is drawn from the grid reference line. If a vertical 3 line power circuit is drawn, set Ladder Offset from Ref line to 90 and turn off Spare rungs 'from the main dialogue box. If the Reference Line and Reference Line Ticks are turned off the offset can

be set to 0. Grid No text Height

This is the height of text in the grid reference line. Grid numbers are placed on layer GRID_NUMBER.

Ladder Width This is the width between vertical left hand to right hand supply rail of the control ladder.

Distance between Ladders This is the distance between the right hand power rail and the left hand power rail for multiple ladders.

Orientation

Only a horizontal configuration is available at this time

Visibility

Reference Line
If enabled the reference line will be visible. The reference line is on layer GRID_REF_LINE.

Reference Line Ticks
If enabled the reference line ticks will be visible. The reference line is on layer GRID_REF_LINE_TICKS.

Reference Line Nos If enabled the reference line numbers will be visible. The reference line is on layer GRID_REF_LINE_NOS

Settings can be made without saving the values as defaults. The settings are only valid for one control ladder at a time. The next time the program is started the values will revert back to there last saved values.

Replace Grid Reference Line

To replace (renumber) the grid reference line to page 25.

Single Digit Reference Number

When reference line numbers are displayed as single digits but cross referencing show numbers prefixed with a zero and when the following conditions apply

  1. Grid reference line numbers are displayed as 1 to 9 in single digit form
  2. Relays and contact cross referencing are displayed as 01, 02, 03.
  3. Insertion of switches or push buttons (with Australian codes activated) are displayed as single digit references 01, 02, 03 etc. eg Australian code for a switch inserted on line 3 would be displayed as S03

To rectify this situation and have reference numbers displayed as single digits (with no preceding zero), edit the grid
reference line with the command DD or DDATTE. Change the first line to 1 as opposed to 01.
Reopen the drawing an continue inserting symbols or cross reference the drawing to display the new reference
numbers.
If two zeros where inserted before the number one, and a push button was inserted on line 3, the tag would appear
as S003.

3 Line Power

Symbols and commands can be accessed from the 3 line power toolbar or from the pull down menu Electrical > 3 Line Power Circuits

A Horizontal or vertical power circuit diagram can be created with three phase or four phase as required. A standard AC motor can be added if required when creating the circuit. If an AC wound rotor motor, DC motor or load symbol is required, delete the existing symbol and replace it with the required symbol. If the three line power circuit diagram is selected immediately after the first control ladder diagram has been drawn with spare rungs, the start and end points will be issued to the user as defaults. If selected before a control ladder diagram has been drawn in the current editing session or less than 3 lines have been left at the top of the ladder, no defaults will be issued and the user will have to manually select start and end points. The Phase ID abbreviations (L1 L2 L3) and the motor terminal ID abbreviations (U V W) are set from the Wire colour Abbreviations command. If these values are not required, delete the contents from the edit box in the Colour abbreviations dialogue command, refer to section Schematic Diagram - Electrical setup - Wire Colour Abbreviations. The circuit is created on layer POWER prefixed with the default Electrical base layer name, eg ELEC_POWER

When inserting symbols on an existing control ladder that has a background grid (vertical and horizontal lines) behind the control ladder, make sure this is on a separate layer and is locked to prevent the background grid being accessed by the program. If the background grid is on a layer whose name begins with `BACK’ eg BACK_GRID or BACKGROUND_GRID, the layer will automatically be locked each time the drawing is opened if the user settings is activated. To activate, refer to section System Setup > User Settings > Enhanced Commands Options

415VAC Power Circuits

When inserting symbols on the three line circuit, the circuit will auto-break all three phases.

Switching

Initiate the command from the pull down menu Electrical > 3 Line Power Symbols or from the toolbar Schematic Diagrams - 3 Line Ancillary.

Once a symbol has been inserted from the icon image, select enter key on the keyboard to bring up the icon image again. If Australian equipment code numbering is activated, protection and metering symbols will be tagged with the code and line number. In some instances, some parts of symbols will automatically have their colour changed to match the colour of the power circuit.

Protection Relays

Protection relays have an outline drawn on layer PROTN_RLY_OUTLINE. This can be turned off if not required.

The CEF protection relay has phase conductors drawn on layer PROTN_RLY_PHASES.

When the 415V Power check function detects that the relay type should be a CEF 1-11 or 1-12 the layer is turned on because the phase conductors pass through the relay. The conductors are illustrated by dashed lines.

If the relay type is a CEF 1-22 or 1-32 the layer is turned off because the phase conductors are bolted to connections either side of the relay. The connections are illustrated by terminal numbers.

Motors and Ancillary Motor devices

In some instances, some parts of symbols will automatically have their colour changed to match the colour of the power circuit.

Relays

Relay coils must be inserted on a line. The user is prompted to select a line, (not the insertion point of the relay). The program will offset the relay by 30 units from the right hand end of the line and auto break the line. The relay can be stretched and moved to a new location if required. All attributes should then be re-aligned with the power rail. Refer to section Align Relays/Lamps/IO Attributes on page 12.

Initiate the command from the pull down menu Electrical > Relay Coil Images or the toolbar Schematic Diagrams Relays or Relays. This will be used as the default until another type of relay is selected.

Files created: Relay.ini or Relay_Clientname.ini

Three main relay types can be directly accessed from the Relay toolbar. They are the general relay symbol and the delay-on-de energisation and delay-on-energisation.

Tag

This is the unique relay identification which must only appear once in a circuit for cross referencing. Any Description type entered will be saved with the tag number. If the tag number is entered again the same description will be displayed s the default. If this is changed, it will over write the last description saved. If an alpha prefix is detected in an last relay inserted, the prefix will be used as a default.

If auto Australian tag codes are activated, the relay tag number will default to the code item and line number eg. Inserting a relay on line 107, will by default enter the tag number K107 in the Tag field.

Description

Line 1 This is the top line of the relay description contained in the relay block Line 2 This is the bottom line of the relay description contained in the relay block

If no description is inserted in line 2, line 1 will be transferred to line 2 in the relay attribute.

Relay Details

If enabled, the relay type can be selected from the popup list. The positive and negative terminals will be displayed in the edit boxes and inserted with the relay. The terminal data is read from file Relay.data and can be edited manually using a text editor to add new relay types.

Command Line Input

If activated, the dialogue box interface will not be used. Prompts will be issued at the command line. If several relays are to be entered with out Tags, it sometimes faster to use the command line and use the enter key to initiate the command again and accept the defaults. To initiate the dialogue box interface, type CMDDIA at the command line and set the value to 1.

Auto Align Descriptions

If there is more than one relay contained in the drawing, this option will be available. If relays are inserted in rungs that are shorter than other rungs (on different power rails), activating this option will automatically align the relay description (and all other attributes including blank values) to the last inserted relay keeping all descriptions aligned down the outside of the control ladder diagram. For manual alignment refer Align Relay/Lamps/IO Attributes page 12.

Retrieve Description

If enabled, and a description has been saved for the current Tag number, the description will be entered in the appropriate lines.

Update

If a description has been saved for the Tag number, the description will be entered in the appropriate lines. If the description is modified the Update button will be enabled. If the new description is to be used for the default, select the Update button.

Relay Image

Clicking on the image will scroll through the different relay types on at a time. Data for the relay type is contained in file

Relay.ini.

The timer relays and contacts have an extra attribute for timer settings.

Command line: rly or relay

Align Relay/Lamps/IO Attributes

Initiate the command from the pull down menu Electrical > Schematic Diagram Tool > Align Relays/Lamps/IO Attributes or from the toolbar Relays - Align Relay/Lamps/IO Attributes.

If relays, indicating lamps or I/O symbols are moved or not aligned vertically, the attributes can be realigned in the x coordinate for relays, lamps and Input Output symbols. The user will be prompted to pick a point to align the attributes to in the x coordinate (vertical alignment)

Attributes with blank values will also be re-aligned.

Clear Relay References numbers

Initiate the command from the pull down menu Electrical > Schematic Diagram Tool > Clear Relays References or from the toolbar Relays - Clear Relay References.

All relay reference line numbers to contacts will be removed.

Contacts

Initiate the command from the pull down menu Electrical > Contact Images or from the toolbar Schematic

- Contact Images.

Contacts Push Buttons and Switches

There are two configurations for each symbol. One for horizontal lines (centre justified attributes) and the other for vertical lines (left justified attributes). The symbol will automatically be aligned with the line when inserted on a line. If the symbol is not inserted on a line, the default symbol will be inserted as horizontal. The last symbol to be inserted will be used as the default when inserting a contact from the command prompt with the short-cut command IS.

It can sometimes be quicker to insert as many normally open contacts as possible at the command line simultaneously, then use the toggle status command to toggle the status of the contact. If object snap is activated and is not set to Nearest, it will be reset to Nearest, the only object snap that can be used, then reset to its original state. If no snap is set it will not be reset.

If Australian codes have been activated and any insertion of a device not operated by a relay (limit switch), is detected with an alpha prefix, the prefix will be used as the default. For example, if the last insertion of a limit switch was inserted with the tag of LS120 as opposed to the default of ZS120, then LS will be used for all further insertions of a limit switch.

Wire numbers can be added any were in the drawing as required. The user is prompted for a point on a line. The wire number will be offset from the end of the line or at the mid point depending on where the user picked a point.

Transferring manual wire numbers into terminal attributes

Initiate the command from the toolbar Wire Numbers - Transfer text wire no to Terminal
Wire numbers that have been inserted as text can be transferred into terminal wire number attributes.

Command line: tmwireno Select Text value <>: select the text wire number Select terminals to update wire number <> select the terminals to update Select objects: 3 found Wire number exists:- 3692 existing wire number not replaced Select next Text value <>: next wire number Select next Terminal for new wire number <>: No Text entity selected, complete Terminals updated: 2 number of terminals updated

Only terminals with no wire number will be updated.

Terminal Type Options

When using terminal type TM6, it will contain a layer TERMINAL_TYPE2, which can be turned off depending on your requirements

Terminal Type 6

When to use wire numbers inserted with terminals or manual wire numbers.

When wire numbers are inserted with terminals, a termination block can be generated and have wire numbers automatically inserted into the terminals. When wire numbers are internal to a piece of equipment and no termination block is required, wire numbers can be inserted a text and can be placed any where on the drawing.

Aligning Wire Numbers

When wire numbers are too close to the terminal, the wire number can be moved. To move an attribute the user can use the AutoCAD grips command. Make sure grips are turn on and select the wire number. The attribute grip will displayed as a hollow square. Select the grip point and move the wire number to its new location.

Other commands available are

  • move
  • move and rotate to the horizontal position
  • move and rotate to the vertical position

These commands can be accessed from the pull down menu Utilities > Attribute Modification or from the toolbars Attribute - Align Attributes or Attribute Position. Refer to section Enhanced commands - Attribute Align and Attribute angle and position

Initiate the command from the pull down menu Utilities > Attribute Modification> Align Attributes or from the toolbar Attribute - Align Attributes.

If there are multiple lines where more than one wire number is to be moved, all the wire numbers can be moved and aligned horizontally or vertically with one selection. If wire numbers as text on the appropriate wire number layer, the text objects will be aligned with wire numbers as attributes in terminal symbols.

Command line: alignatt Select Attribute to move <>: select the attribute in a block to move and align X or Y Coordinate X/Y <X>: return to align in the x coordinate or type Y or the y coordinate Pick new point to align to <>: pick a point to align all attributes to Select blocks to align attribute <>: select all blocks to have attribute move and align

Terminals should not be inserted on two intersecting lines. The first line detected will determine whether the symbol is to have left or centred justified attributes. When terminals are placed in close proximity to each other, wire numbers may run over top of other wire numbers or terminals. They can be repositioned from the Attribute Toolbar or by using AutoCAD's grips if on. If wire numbers begin to make the drawing congested, wires numbers can be made invisible but remain as an attribute to the terminal which is required to produce terminal blocks. This can be done from the Attribute Toolbar height button. To make the wire numbers visible again type ATTDISP ON. Regenerate the drawing and select

Produced for CADWEST (WA) Pty Ltd Schematic Diagrams

the same command to make attributes invisible and select the attributes that are invisible. This will toggle the attributes visibility state.

Extract Terminal Data

Initiate the command from the pull down menu Electrical > Terminal Ancillary > Extract Schematic Diagram Terminal Data or from the toolbar Terminals - Extract Terminal Data.

Terminal ID, terminal number and wire numbers can be extracted and used to generate termination blocks. Refer to section on Termination Diagrams -Termination Blocks

Renumber or Increment Terminal numbers

Terminal numbers in terminals or terminal blocks can be renumbered or be increment.
Initiate the command from the pull down menu Electrical > Terminal Ancillary > Increment/Renumber
terminal numbers or from the toolbar Terminals - Increment/renumber Terminal Nos.

To increment terminal numbers

To increment terminal numbers, select Increment under the Type and in the Increment Value data field enter the value for each terminal to be incremented by. Select Ok. At the command prompt, select the terminal type to be updated. This filters out only that terminal when prompted to select all terminals to be updated. If any other terminal is selected that does not match the original terminal, it will not be updated.

To re number terminal numbers

To renumber terminal numbers, select Renumber under the Type and in the Start No field enter starting number for the first terminal. All subsequent terminals selected with have a value one (1) more that the last. Selecting the same terminal twice will renumber the terminal by two (2). Select Ok. At the command prompt, select the terminal type to be updated. This filters out only that terminal when prompted to select all terminals to be updated. If any other terminal is selected that does not match the original terminal, it will not be updated.

If a terminal number is prefixed with a letter eg A14, then only terminals of the same type and with a same terminal
prefix will be changed even if other terminal types or terminals with different prefixes are selected.
This program can also be used on termination blocks.

Keyboard short-cut command: rn

Change Wire number

Select command from Tool bar Wire Numbers or from the pull down Menu Electrical > Wiring > Change wire number. Changes wire numbers in terminals by selecting a terminal with a wire number or by typing a new wire number at the command line.

Clear Terminal Numbers

This function removes terminal ID's and or Terminal numbers

Initiate the command from the pull down menu Electrical > Terminal Images or from the toolbar Terminals,

Schematic Connection Points

Automatic connections

Initiate the command from the pull down menu Electrical > Connection Points > Automatic Connection Points or from the toolbars Schematic Diagrams - Connections Points or Connection Points

When all grid lines have been drawn and trimmed, connection points can be inserted at each intersecting lines if no connection point already existing. If grid lines are modified again, select this option again to re check connection points. Connection points will be added to an end point of a line that is perpendicular to another line. The line weight must be 0.35 and linetype must be continuous.

Command line: connect Select objects: select objects by window/crossing or type ALL for all entities Adding Connection point: 1..2.. displays progress Connection points added: 3 displays modifications

In some instances were a connect point is not inserted automatically, is because the linetype will be set to bylayer or the lines do not exactly meet.

Manual connections

Initiate the command from the pull down menu Electrical > Connection Points > Manual Connection Points or from the toolbar Schematic Diagrams - Connections Points or Connection Points.

This command is used when the intersecting line weights are thicker than 0.35 to allow for the connection point to be scaled up slightly to give better definition. It can be used for control circuits if one or two points are required, any more, it would be quicker to use the automatic connection point command. Manual insertion of connection points will take into account the line weight (determined by colour) of the intersecting lines or the width of a polyline. The connection point will be scaled up to allow for plotting line width. If a connection point is inserted on a polyline, the insertion scale factor will be twice the width of the polyline, if inserted on a 0.50 line width the scale factor is

1.15 and for 0.70 and 1.0 line width the insertion scale will be 1.25 to give the connection point definition.

DCS/PLC

Initiate the command from the pull down menu Electrical > DCS/PLC symbol images or from the toolbar Schematic Diagram - DCS/PLC.

Select a DCS/PLC symbol. The description for output symbols appears above the symbol and the input symbols to the right which may have to be aligned with the right hand margin. Refer to section on Aligning relays, lamps and I/O page 12.

There are two sizes of symbols, large and small. Once a Small symbol has been inserted, trying to insert a Large symbol of the same type will result in the insertion of a Small symbol type and vice versa.

Ancillary Distribution Board

Initiate the command from the pull down menu Electrical > Distribution Board

Circuit Breaker Types

There are two types of symbol representation. Type one (which is the default shown in the image dialogue box above) is located in the symbol <acadrootdir>\DB\Form1 and type two are located in <acadrootdir>\DB\Form2

The layer ELCB_EARTH can be turned on to display and earth symbol beneath each symbol if required.

Type 1, Type 1 with earth, Type 2

Detached Reference Line points

This function allows the user to reference two separate parts of a circuit to each other in detached form. Initiate the command from the pull down menu Electrical > Connection Points > Reference point To and insert the symbol. When the prompt for `Tag ID' is displayed, enter a tag id which is also to be entered at the `From' end. For example `REF1'.

To insert the corresponding end, initiate the command from the pull down menu Electrical > Connection Points > Reference point From and insert the symbol. When the prompt for `Tag ID' is displayed, enter a tag id which is to be entered at the `To' end. For example `REF1'. The Tag ID is contained in an invisible attribute. One end of the reference must be the `To' end and the other the "From' end. Which is inserted first is not relevant. The line number of each corresponding ends will be entered automatically into each symbol when the update

Relays/Contact. If one end does not have a complementary end, an error message will be displayed when updating. The line number is taken from the insertion point of the symbol. If the attributes are moved, the insertion point may not be obvious to the user. If the lines numbers do not match up with the grid reference line move the blocks up or down half a line then cross reference the drawing again.

The symbol names are SDHREFT and SDHREFF and default descriptions can be entered when the symbols are edited. The default description top line is blank and the 2nd bottom line default is `LINE'. This could be edited to read `REFER LINE' if required.

Inserting the block SDHREFF with the same tag number as a relay will cause the reference block to be cross referenced to the relay.

Inserting the block SDHREFT with the same tag number as a contact will cause the contact to be referenced to the reference block.

Inserting the reference blocks SDHREFT and SDHREFF with the same ID tag (invisible data field) will cause the to reference blocks to be cross referenced to each other.

The reference block SDHREFT is the equivalent to a relay and the reference block SDHREFF is equivalent to a contact.

Cross Referencing Relays and Contacts

Initiate the command from the pull down menu Electrical > Automatic Check/Updating > Xreference Relays/Contact or from the toolbar Schematic Diagrams - Relay Contact Xref.

A Grid reference line must be contained in the drawing before cross referencing can be applied. To insert a grid reference line, refer to section for creating a control ladder and grid reference line page 4.

When all relays and contacts have been inserted in the drawing, cross referencing of relay to contacts can be executed provided a vertical grid reference line exists. Grid numbers will be updated between relays and contacts with the same Tag number. The grid reference line number of the relay coil will be inserted below the contact and the contact grid reference line number will be inserted into the relay description. If Australian tag codes are used then grid reference line numbers do not have to be entered into the contacts.

Contact Tag No MC-2 and Relay Tag No MC are NOT a match

Up to six (6) reference lines can be use on one drawing. Three line circuit breaker and isolator symbols will also be treated as relays and will be cross referenced to (auxiliary) contacts (not single phase CB symbols). If any relays or contacts are moved from there original control ladder rung, cross reference the drawing again to update line reference numbers. If any errors are detected, they be written to one of two files. If the drawing is being checked individually, a file will be created derived from the drawing name with file extension .log or if the drawing is being checked in batch control mode using Electrical > Automatic Check/Updating > Check all Drawings, the file will be created named Update.log. If either file exists the file will be appended to. The file type is ASCII text form and can be viewed or edited with a any text editor. The modifications to the drawing can be printed out and the relative sections of the drawing high lighted by clouding.

Relay reference number order

The order of the line number references can be set to numerically and displayed over one or two lines or with the normally open contacts displayed in the top row and the normally closed contacts displayed in the bottom row, refer to section Electrical Setup - Electrical Schematic Diagram Settings.

Numerical Order

Prevent Cross Referencing

It may be necessary, in some rare occasions, to make manual modifications to grid reference numbers or tag numbers. If this is required, then automatically cross referencing the drawing will remove any manual additions from relays. The drawing can be prevented from being cross referenced by locking the drawing, refer to section Electrical Setup Electrical Schematic Diagram Settings.

Multiple Drawing Cross Referencing

When the control diagram is spread across two or more drawings, the drawings must be tagged for multiple drawing cross referencing. A reference to the other schematic diagram or diagrams must exist on the drawing being cross referenced as Text or Mtext and can be underlined if required. If the reference drawing numbers in the current drawing are contained as attributes in blocks, the drawing reference numbers must still be placed on the drawing as text. This can be achieved by placing the reference number as Text or Mtext and the layer changed to DEFPOINTS. Anything residing on this layer will not be plotted. For example if the drawing number is W314-E-101 revision A and the file name is W314E1010A enter W314-E-1010A or W314E1010A on the drawing. Provided the drawing number format has been setup (refer to section System Setup Getting Started - Drawing Number Format) the text will be located and the appropriate data from the drawing read into the drawing.

Note Each drawing being cross referenced must have a unique
grid line numbering system e.g. the first drawing grid
line will be numbered 101 to 199, the 2nd 201 to 299 and
so no.

Files Created: <Drawing file name>.RLY Contains relay data <Drawing file name>.NOC Contains normally open contact data <Drawing file name>.NCC Contains normally closed contact data

To Cross reference multiple drawings:

  1. From the pull down menu Electrical > Schematic Diagram Tools > Tag Drawing for Multiple Cross Reference or from the toolbar Schematic Diagrams - Relay Conatact Xref..
  2. From the pull down menu Electrical > Automatic Check/Updating > Download Cross Reference data - Current Dwg Only or
  3. Open the next drawing for cross referencing. Repeat step 1 and 2
  4. If there are further drawings in the series repeat step 3.
  5. If this is the last drawing in the series to be cross referenced, cross reference the drawing in the normal manner.
  6. Back track through all the drawings opened in step 3 and cross reference the relays and contacts from the pull down menu Electrical > Automatic Check/Updating > Xreference Relays/Contact or from the toolbar Schematic Diagrams - Relay Contact Xref.
Error checking
  • Checks for control relays without contacts
  • Checks contacts without a control relay
  • Checks for duplicate relays (relays with the same tag number)
  • All detected errors are written to a text file.
Removal of Contact line numbers

If Australian codes are used for equipment tag numbers, the relay reference number in the contact is not required. If the contact line number setting option is set to Not Displayed line numbers will not be displayed in contacts. The reference numbers can be manually removed after cross referencing using the command Clear Contact References numbers page 14.

Renumbering Tag numbers Wire Numbers Replace Reference lines

Replaces all vertical reference lines with the same line spacing with the
new line number

Equipment Tag Numbers
Renumbers all relays and contacts with the new tag number.

Wire Numbers Increment
Renumbers all wire numbers in terminals are text wire numbers. Wire numbers as text must reside on layer WIRENO.

If the Vertical reference line is not selected and either of the other two options are selected, the user will be prompted to
select the relays, contacts and wire numbers to change. If a section of the control diagram is moved on the control
ladder, then that portion can be selected for modification. If the Vertical reference line option is selected then the whole
drawing will be automatically scanned and updated.

Increment

Enter the value to change reference lines and tag numbers by (can be negative). If the Wire Numbers is enabled only the wire numbers will be incremented by the increment value as indicated in the Type area. If either the reference line or tag numbers is enabled the wire numbers will be incremented by 10 times the increment value eg if the increment value was 100 the wire numbers would be incremented by 1000.

Wire number filter

Not all wire numbers may be required to be changed. Any wire number matching the filter will not be changed. For example, a filter containing *48V*,*24V* would not change wire numbers 48VDC or 24VDC

415VAC 3 Line Power Circuit Design Check

If a 3 line power circuit exists on the drawing, initiate the command from the pull down menu Electrical > Options > Automatic Check/Updating > 415VAC Power Circuit Design check.

Drive rating

If the file <acadrootdir>\Data\Power\Sld_Mcc.csv or Sld_Mcc.txt exists, it will be scanned for the equipment number and if a match is found the motor rating will be compared and if different, updated.

The Motor symbol on the schematic diagram must contain the equipment tag number in the appropriate attribute for the rating to be retrieved from the single line diagram data file.The first three fields in the data file must be Equipment Number, Drive Rating and MCC Number.

Protection Relay

If the data file <acadrootdir>\Data\Motortxt exists, it will be scanned searching for the nearest match to the motor
rating and the protection relay type will be updated if different.
If the Motor.txt does not exist the file Protection.txt will be used if it exists.
If a S & S CEF 1-12 or a CEF 1-22 protection relay is used in the circuit, changing the drive rating will change the
representation of the symbol. Refer to Protection relays page 10.

Circuit Breaker rating

If the data file <acadrootdir>\Data\Motortxt exists, it will be scanned searching for the nearest match to the motor
rating and the circuit breaker rating will be updated if different.
If the Motor.txt does not exist the file MCCB.txt will be used if it exists.

If the data file <acadrootdir>\Data\Motortxt exists, it will be scanned searching for the nearest match to the motor
rating and the isolator rating will be updated if different.
If the Motor.txt does not exist the file Isolator.txt will be used if it exists.

Fuse rating

If the data file <acadrootdir>\Data\Motor.txt exists, it will be scanned searching for the nearest match to the motor
rating and the fuse rating will be up dated if different.
If the Motor.txt does not exist the file Fuse.txt will be used if it exists.

Ammeter and CT ratio

If the data file <acadrootdir>\Data\Ammeter.txt exists, it will be scanned searching for the nearest match to the motor rating and the fuse rating will be up dated if different.

If any changes are made or errors detected, they will be written to one of two files. If the drawing is being checked individually, a file will be created derived from the drawing name with file extension .log eg 3250e001.log, or if the drawing is being checked in batch mode, the file name will be Update.log. If either file exists the data will be appended to the file.The file type is an ASCII text file and can be viewed or edited with any text editor.

Creating a Schematic Diagram

  1. Insert an A1 drawing sheet.
  2. Check schematic diagram settings.
  3. Add a control ladder.
  4. Add a power circuit
  5. Insert relays, contacts, terminals and appropriate ancillary equipment.
  6. Trim all circuit lines then add connection points.
  7. Cross reference contacts to relays in the schematic circuit and 3 line power circuit.
  8. Down load terminal data for creating the Termination blocks.

Schematic and Termination Diagram Tables

This function is used when a standard schematic or termination diagram is used with a table containing a list of drives. The data is contained in a row for each drive. For examples, refer to the standard table block drawings, SCHEMTABLE and TERMTABLE located in the <acadrootdir>\Lib\Schematic\Tables directory.

Initiate the command from the pull down menu Electrical > Fill in Schematic/Termination Table

Files Created: <Data input file name>Schmnos.csv

The data is read from the same file used to create the single line diagram. As the drives are inserted into the table, the drawing number for each drive will be written to file <Path of Data Input FIle>\<Data input file name>Schmnos.csv eg. SLDSchmnos.csv, which will be used to update the drawing numbers on the single line diagram. Once the table has been filled in, the file will continue to be scanned for any further drives that match the criteria. If any further drives are located in the file, a message will be displayed indicating how may drives remain to be inserted in the next table, giving the user an indication of how many new drawings will have to be created. When there are no more drives match the criteria, a message will be displayed indicating the standard drawing type is complete and the next standard drawing type can be started. Two blocks must reside in the drawing, the header for the table and the block which contains the data.

Table Header

The Table Header block contains the data for the criteria table. The header block name must be named TABLEHDR in both schematic and termination diagrams. The data can be changed manually or the program will update any changes to the header block from data entered into the dialogue box

Data Block

The data block for a schematic diagram must be named SCHMDATA (for the schematic diagram) and TERMDATA (for termination diagrams). The data attributes must line up with the columns in the table, these can be altered to suit.

The following attribute names must exist to be updated:

Equipment No EQUIPNO
Rating RATING
Description DESCRIPT
Wire Ferrule No FERRULE

Any other attributes can be added in any order to the data blocks as required. Data must be entered manually for any other attributes in the block. If the ferrule number is not required, edit the data block and remove the attributes.

Table containing drive data

Add Table Data

The criteria displayed in the dialogue box is saved in the Table header block.

Type

Determines when a record is added to the table.
All Criteria
Applies all criteria from the Drive data from the Data Input File, MCC,
Rating, Module Type, Key Words and No of drives

Module Type Only
Applies the value contained in the module type column from the Data
Input File, all other criteria is ignored. The module type must contain a
number eg Dol1, Dol2, Rev1, Rev2 etc. If the module type is DOL1 then
the Data Input File is scanned looking only for the module type. Refer to
the section on the Single line diagrams Module Drawings.

Data Criteria

Sets the data for the criteria, Type - All Criteria must be enabled. MCC Holds a list of all unique MCC Module Module type Key Words Any word contained in the description or equipment

number field from the Data Input file. Refer to the section on SLD Criteria Table page 1 for more information on filters. No of Drives This is the number of drives feed from each MCC module. Defaults to 1, defaults to 1 if 0 or a null

value. PLC Control This is for future use and does not contribute to the criteria to data. Local Control This is for future use and does not contribute to the criteria to data

Rating Criteria

Min kW>= This is the minimum value for the drive rating. The value must be equal to or greater than this value. Max kW>= This is the maximum value for the drive rating. The value must be less than the value in this table.

Table Settings

Max No Rows This is the maximum number of rows in the table. If the table contains 25 rows, the value can be 25 or less. By setting the value to less than the maximum number of rows in the table, will give the users some lea way for extra drives to be inserted later if required. The value indicates how may drives will be read before the next drawing has to be created The next drawing will start reading the data from the last drive read.

Row Spacing This is the spacing between rows in the table.

Re Start scan If it is required to start from the beginning of the file before all drawing are complete, enable the check box.

If the drawing has been started, the last drive inserted will be the starting point for the next table (if there are more drives than rows in the table). If the user is required to start from the beginning of the Data Input file again, enable the Start from the beginning of Data Input file check box.

The data contained in the table data block is as follows Attribute prompt Description MCC No Contains ‘All MCC's' or an MCC no, 1400-MCC-001 Min Rating the value 0.38 will be evaluated as 0.38kW and greater Max Rating the value 75 will be evaluated as less than 75kW eg 74.99kW No of Drives 1 or 2, if blank, the default will be 1 Module DOL, VSD, Rev... if blank, the default is DOL Key words eg *CONV* any description containing the letters CONV, or maybe left blank PLC future Row spacing spacing between rows in the table, the default is 7.5 No of Rows number of rows contain in table, the default is 24

To create a standard schematic with a table.

  1. Initiate the command from the pull down menu select Electrical > Fill in Schematic/Termination Table
  2. Select the MCC equipment number or select ‘All MCC's'
  3. Fill in the criteria if required, eg ratings, module type, and/or key words
  4. Enter the row spacing value
  5. Enter the number of rows (number of drives to be inserted on the drawing)
  6. Select the OK button

If a message indicates there is further drives remaining, created a new drawing and follow steps 1 to 6 again until a message indicates there are not more drives in the Data input file matching the criteria.

Once the 1st drawing has been created for a particular standard schematic, save the drawing modifications (SAVE), then save the drawing as the next drawing number (SAVEAS). Change the update the drawing number in the drawing sheet and run the program again. The program will delete all data blocks and start from where it finished on the previous drawing.

If you want to restart reading the data from the beginning of the Data Input file enable the ‘Start from the beginning of Data Input file' check box. Continue through the drawing series again.

There is no update feature as new drives in the data input file will cause drives to be moved from drawing to drawing. To update the drawings, plot out all drawing to be updated then enter the 1st drawing in series and run the program from the beginning. Current data will be deleted and reinserted as read from the new data input file. Plot out the drawing again and compare the two drawings for updates. This will indicate that drives have been added or removed. Make the appropriate revisions to the drawing. If there is a REV attribute in the data input file this can be inserted into a attribute in the data block to indicate the revision. If the single line diagram has been updated previously and the schematics are being updated from the same data input file, then any modifications will be written to the Sldupdate.log file will indicate the same changes to the schematic and termination diagram table data.

Update Schematic Drawing Numbers on Single Line Diagram

Once all the schematic diagrams have been created, the schematic drawing numbers can be entered into the drive symbols on the single line diagram. Initiate the command from the pull down menu Utilities > Attribute Data Update. The default information should by automatically entered into the data fields if this command has not been used after filling in the schematic diagram data tables. The default files required are, Attribute template file:-<acadrootdir>\Data\SldSchmdrgno.att Input Data file:-The single line data file used to create the
