Greetings Tim ...
first of all, the (well-intentioned) information that you've been given above relates to the SLC-500 family of processors ... it is NOT correct for the larger (and more complicated) PLC-5 system that you're working on – so don't let it confuse you ... key point: all Allen-Bradley systems are NOT the same ...
attaching your program was a GOOD idea ... unfortunately the I/O Configuration table hasn't been filled out – so the documentation is sort of sketchy ...
based on what I can tell, you have TWO analog input modules and each of these APPEARS to be an 1771-IFE ...
I've done my best to extract the information that you need based on several ASSUMPTIONS ... if you have any additional questions, feel free to call me up (even this weekend is ok) and I'll try to help you through this ... note that I will be offline until sometime tomorrow – so if you post anything here (or if you send me an email) I won't get the message today ...
I've attached two pictures below – one for each analog input module ...
see if the addresses that I've circled in red help you out ... notice that each (ASSUMED) 1771-IFE analog input card has 8 channels available ... the address descriptions (the existing documentation) seem to make sense – but naturally I can't be sure without knowing exactly how your system is actually (physically) put together ...
finally, you should already know that the 1771-IFE modules contain JUMPERS which select whether each channel is wired for voltage or wired for current ... if you're moving a field input from one channel to another, it would be a good idea to open the module and make sure that the jumpers for the "new" channel are correctly arranged to match the input signal ...
if you need more help, it would be a good idea to confirm exactly what type of analog input modules you're using (full catalog numbers please) – and also how those modules are arranged in your chassis ... knowing the actual size of the chassis would be helpful too ... I've ASSUMED that you're using a sixteen-slot local (processor resident) chassis ... suppose that we LETTER each of the slots "A" through "Q" to remove any "one-slot" – "two-slot" – "half-slot" addressing ambiguity ... yes, that's a total of SEVENTEEN slots – not sixteen ... in a PLC-5 system the "extra" (uncounted) slot is for the processor ... (the label on the chassis "lies") ... so ... if you consider the processor to be located in slot "A" then the two modules that I THINK you have for your analog inputs APPEAR to be located in the slots lettered "O" and "P" ... if your hardware is different, then you might want to nail down how it's actually physically arranged before you go much further ...
one more note: your "local" chassis (the one with the processor in it) is using the "one-slot" addressing mode ... IF (that's a big IF) you actually are using another ("remote") chassis too, then there's no guarantee that it is also using "one-slot" mode ... so – IF there's another chassis involved, it would be a good idea to check the DIP switches located on that chassis' backplane ... note that the "slot" addressing mode for a remote chassis can NOT be conclusively determined from the program file ...
hope this helps ... good luck with your project ...
