Cable Codes of PLC Schema

Select tab, PLC group PLC System Drawings Menu.
Browse and edit the IO lists of project PLC systems.
Generate circuit diagrams based on IO lists.

Cable codes of PLC system are automatically generated depending on input device / block and given parameter CB_NAME in the system settings LSETUP.

ED 2013 -version supports three cable code settings:

CB_NAME = 1:

Generating Norms of Cable Codes

Beginning	End	ID
Logic	IO device	W + logic's 1. I/O address (separate supply cable ...+ L)
Junction block	IO device	W + Block code + 1. number of signal contact pin
Logic	Junction block	W + Block code + A/B/C...
Junction block	Junction block	W + Block code + 1. number of contact pin

CB_NAME = 2:

Generating Norms of Cable Codes

Beginning	End	ID
Logic	IO device	<Logic's system code> - <I/O device code> (extra supply ... + b )
Junction block	IO device	<Logic's system code> - <I/O device code> (extra supply ... + b )
Logic	Junction block	<Logic's system code> - <target junction block code> (extra cables ... + a/b/c... )
Junction block	Junction block	<Logic's system code> - <target junction block code> (extra cables ... + a/b/c... )

CB_NAME = 3:

Generating Norms of Cable Codes

Beginning	End	ID
Logic (no block)		To the beginning of the code: <Logic system code> -
Logic (block)		To the beginning of the code <Logic block code> -
	IO device	To the end of code <IO device code> (extra supply ... + b )
	Junction block	To the end of code <target junction block code> (extra cables ... + a/b/c... )

Parametric generating of a code (ED 18.0 ...)

It is possible to add a parameter LOG_CBFIX in the logic system settings LSETUP, with which edit or replace the cable label created by the system.

Parametric value of LOG_CBFIX can be either a parametric text, that refers to cable's end point data, or it can be a name of a software, that generates the corrected code.

If a name of a software is given, the cable code edited in replacing chart's variable $CB_EDITED has to be returned by the software. If the software does not return the value, or the replacing of the parametric text is not successful, the original cable code generated by the system is used.

Text symbols used in generating of parametric cable code

Text symbol	Description
#$LSYS#	Naming of system
#$E1#	Beginning's system code
#$P1#	Beginning's position
#$L1#	Beginning's device code
#$E2#	End's system code
#$P2#	End's position
#$L2#	End's device code
$CB_EDITED	New cable code returned by the parametric system

For example: W is wanted in front of the device code, and the beginning's position and device following it, then a hyphen and the end's device.

LOG_CBFIX parameter is added in the system settings and value is defined as:

W#$P1##$L1#-#$L2#
