Dear all,
I have come across a problem.
A plant is controled by an S314C-2DP connected to an OP177B.
In the operator panel there are three I/O fields which are written directly in a DB in the CLP.
They are configrued as I/O with no special permission and no restrictions. They can not be, however, changed in any way. Whenever a new value is given it just retains the old value and do not change.
These are in the HMI controlled and only read in the CLP.
Anyone has an idea about what can be happening?
I have no whatsoever experience with WinCC flexible. First project is to solve this problem. =]
Thanks
