We have a S5-PLC CPU 115U, and its running.
But, when I set the selector in Stop and then back again in RUN: CPU doesn't restart.
When I do an overall reset and then selector to run, plc is in run.
If I then download first the DB's and then the PB, OB and FB: PLC stays in run, and we can work.
But I want to know why I cannot make a cold/warm restart...
We work with the IBH-softec S5-S7 for Windows:
ISTACK-error: "coupling flag transfer list corrupted"
Does anyone knows this error?
I'v tried (after an overall reset-with selector in STOP) to download only the DB. Even then PLC stays in STOP when I set the selector in RUN.
See in attachment a picture of the ISTACK
