In one of our projects we have:
- New Ignition system for storign records
- Old system doing the same.
We have setup a transaction group to store the date in the same manner as the existing old system did.
There are 2 tags in the PLC to request each SCADA to store the Date
Both work the same way:
0 = idle, 1= SCADA to store date, 2 = SCADA has stored the data.
Every so often at random intervals the new ignition system misses a record, the old system does store the record.
There is no error in the ignition system log to say the transaction group failed.
Ignition is comunicating via kepware to the S7 PLC.
Any suggestions on this?
