Having been called for a rush intervention on a system, there in-house programmer emited his opinion that some rungs must have disapeared from the PLC.
"Say what?"
He told me that a few times it happened on some of his system (Mitsu - AB - Siemens).
Being full of wisdom myself (sure) and since he was paying me a great deal to be there I went on to tell him that "In the field of electronic everything can happen." but IMHO he was full of $xxxt.
Checksum between sections of the boards inside the PLC cannot permit it.
Heve you ever seen anything like this?
