Is anybody out there familiar with diagnostic systems for use with
programmable logic controllers (PLCs) like the Allen Bradley PLC-3 for
example. I heard there are diagnostic systems which use some sort of
bit address mapping. I don't know if this is built into into the actual
PLC (I think I heard once that Honeywell PLCs do this) or is external
to the processor. Any info. would be greatly appreciated.

Thank you.
