4 Specify how you want the module to be placed in the drawing.
5 Click Start.
AutoCAD Electrical constructs a set of PLC I/O drawings based on the
information carried in the PLC spreadsheet. Ladders and modules insert
automatically, breaking at the bottom of one ladder and continuing on
the next.
Change and use PLC I/O settings
You have control over many aspects of how these drawings auto-generate.
You also can adapt this tool to an existing spreadsheet or database format that
is different from the example demoplc.xls file format. You can change these
settings each time you run the program or change them once and save your
settings for future use.
