Generate PLC layout modules
AutoCAD Electrical can generate any of hundreds of different PLC I/O modules
on demand, in a variety of different graphical styles, all without a single,
complete I/O module library symbol resident on the system. Modules
automatically adapt to the underlying ladder rung spacing, whatever that value
is, and can stretch or break into two or more pieces at insertion time. It is possible
because AutoCAD Electrical generates PLC I/O modules through a parametric
generation technique driven by a PLC database (ACE_PLC.MDB).
The PLC database contains the stack sequence and text values to annotate onto
each symbol in the stack. As AutoCAD Electrical builds the module, it reads the
underlying ladder rung spacing and spreads out the stack or compresses it to
match the rung spacing. During the insertion process, you can interrupt it to
break the module and then restart it at a different location.
