I have experience with converting PLC5 to Logix but this system has two PLC5s, one of which is used in adaptor mode. I'm wondering if someone here can help me figure out what needs done differently here.
The PLCs were originally the classic series (5/15, 5/25, etc.) since upgraded to a 5/80s with Ethernet side car. The Adaptor PLC5 was added in a remote rack containing nine total analog input & output modules and handles over a dozen PID loops because the original Scanner PLC5 didn't have the horsepower to handle all of the block transfers & PIDs, so I've been told.
We aren't granted a lot of time for changeover, so the 1771 IO stays put and the new Logix rack contains a processor, EN2T & one or more DHRIO cards. On other projects, we would install the PLC5 in a standalone rack, put an ASB in the old rack 0 and renumber it before converting the program. This way we don't have to worry about address differences and downtime is reduced. Not sure this will work with so many analog cards in one rack!
Any insights on how to address this dilemma and the Adaptor PLC in general will be greatly appreciated. Thanks in advance.
