All,
We have a WAGO plc which we read via modbus. There are just 18 PVs in this IOC, read as two blocks from the plc. All the PVs briefly go invalid for ~ 5 seconds (as reported by clients like Alarm Server, Archive Appliance)
Am I correct in assuming that if this was because the IOC lost its connection to the plc, this would be reported as an error in the IOC console [asynTraceMask is not explicitly set so it is the default value of 1?]
Thanks,
