We intend to upgrade a PLC5 control system to ControlLogix. It is our intention to use the existing PLC5 I/O by removing the 5/25 processor and replacing with a 1771-ASB and connectiong via RIO to a 1756-DHRIO card in the new ControlLogix chassis.
Setting this up looks reasonably straight forward to talk to the Digital I/O, however we are a little unsure as to how to approach the Analogs. Has anybody done this before and if so your help would be appreciated.
