    In some industries, it is quite popular to draw individual inputs or outputs as separate symbols being drawn on the schematic that they are controlling. In addition to drawing the individual I/O, some clients ideally like to repeat the information of the I/O in a schematic displaying the slot. In an intelligent CAE system, this is effectively duplicating the I/O. In addition the slot is repeated again in a “top down” view of the rack with slots (still within the schematics) duplicating the slot again.

    So how can this be achieved without duplicating the I/O and the slots for reporting purposes?

    Utilising one of the standard symbols out of one of the IEC libraries as a starting point, a new analogue input was created:

    An individual I/O utilises the Edit PLC dialogue so that address, descriptions etc can be assigned and kept track off. The PLC tag being specific to the slot rather than the rack.

    A PLC slot was created as a “DN” category component as the Edit PLC dialogue wouldn’t be required for simply the power connections:

    The symbol was edited so that cross reference information only displayed the sheet and grid reference of the individual I/O:

    If you then want a list of the individual I/O being displayed within or next to the slot, a PLC Component Connection report can be run:

    The slot that’s displayed in the schematic representation of the rack (not footprint) is drawn as a child “DN” category component. This is linked to the parent “DN” category slot above:

    The rack being drawn as a parent DN category component but with the tag being specifically unique to the rack:

    Finally with the slot being positioned, our schematics now result in:
