Hello Everyone,
I wrote a program that I need to use on two different chassis configurations, where one has one less I/O Module than the other. I am using a compactlogix L24ER processor and RsLogix 5000 version 20 one both of them.
My expansion I/O configuration in RSLogix 5000 Expansion I/O on the larger Chassis
(4) 1769-OW8
(5) 1769-IF8
(6) 1769-IF8
(7) 1769-OF8C
The chassis that uses one less card doesn't have the number (6) I/O card. I was told by Rockwell that you can inhibit the (6) module and it won't look for it. The only issue I am having is that the (7) module is coming back with an error that says
(Code 16#0022) An invalid reply was received. Reply service code does not match the requested service code.
I have looked on the knowledge base and made sure the keying was set to compatible for that 1769- OF8C module, and the RPI was larger than it was supposed to, and even set it larger to no effect. This same module works fine in the program on the larger Chassis. It just doesn't on the smaller one where we need to inhibit the card.
I am trying to make sure I am not
1. mistaken that I am supposed to be able to inhibit a card in the middle of the I/O configuration list and it will work ok. The knowledgbase suggests it works for controllogix, in article 119883, and the guys I can immediately talk to from Rexel/Rockwell seem to think it should work, but they don't program all the time.
2. There isn't some other issue that could be causing the error unrelated to the whole module inhibiting factor.
I don't have another module to test with right now.
Any thoughts? Thanks.
Alfred
