Good afternoon,
I want to understand this old piece of logic I found in an old program (RS Logix 500 on SLC 5/03).
I have two rungs here in a program, one output signifies a major fault in a program, while the 2nd output represents a minor fault.
The source in both MVM is the same. When I toggle output N7:2 (which I want to incite a major fault with), it changes the source from 0 to 4. I don't understand how that happens and need explanation for this. See the 'fault' image for details.
Also, after the 0 becomes a 4, my destination for both MVMs remains 0 (but I am doing this offline, unsure if I need to go online). I want to assume the masks are in Ascii, which would make sense that the destination stays 0 for both.
At the end of the day, I need my 'crankpin generator fault' to incite a major fault which will abort the cycle. Apparently, it has not been doing this for years according to the setups / techs on the line.
Thanks and have a great day!
