In my project, I have 2 CPU which are A and B.
Recently, I need to configure the WinCC Flexible to finding the Master CPU for change connection.
I have some script to change connection by using the clock bit to trigger the change connection script under the change value event of the tag.
However, in this script, it can not identify the CPU master to change connection. My script can only change connection when the running CPU shut down suddenly.
In case, when the power source is disconnected. When the power source start up again. The case may be:
1. the Master CPU is B
2. the WinCC Connection is in CPU A
So, I need to write the new script under the scheduler function with every 1 min to check the master bit (db5 dbx 9.0) to change connection.
But, I got some misunderstanding:
1. under scheduler, can it check the master A bit and master B bit to change connection?
2. will it trigger to change connection ?
3. under the master tag , should i need to add the script under change value?
Do you guys have any suggestion or idea??
many thanks!!!!
