I have a problem with a message instruction. I will explain what the situation is.
In this factory we have several PLCs controlling different types of machinery. We have a master PLC that we use for gathering data from the other PLCs.
They are complaining that the time stamps are not matching up on the SCADA. We think this is happening because if a panel is switched off then the message instruction will go into error. Could this be the issue that when the message is in error its not moving on to the next stage message instruction because the one that is in error is hogging the communication.
I will enclose pictures of the message program logic.
