1771 AB I/O module in a remote rack, need help changing the scaling
(OP)
I am trying to change the scaling using rslogix5000 and was wondering if there is a way i can do it without shutting down the processor, i am using BTW and BTR's to read and write the information to the processor.

Its been a long time since I've used an analog module, but I think there are words in the BTW file that specify scaling. If thats the case my next question becomes what happens when you change the values?
One pecularity of the module was that if you wanted to use scaling you had to specify scaling for all channels even if not used.

If so and they get reset get the cross reference for the particular tag you are using and look at any MOV, COP instructions.
In RS5000 cross reference gets you a better report, it is confined to a single window and indicates what instruction is associated with the address.
Assuming

I can't find the BTW in the CLX instruction set. So can you tell me what instructions are used for the module. Or better yet send me the program.
