I have 2 Proxys (connected to the same I/O block) that are pulsing when they are made. They replaced the I/O block a while back, but the issue resumed. I tried switching the proxy connections on the I/O block to an unused space to ensure the replaced block was not bad but the pulse would follow which lead me to believe it is a configuration issue. After pulling Ladder and running a cross reference, I was not able to locate the 2 DI’s. Since these are only used for part check verification, I would expect them to be inside the Ladder but wanted to double check.
Do you have any other suggestions that I might be overlooking?
