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.
