Connection Monitoring
Monitoring interval (provider data holds)
The monitoring interval is determined by the "DataHoldFactor".
If the provider data of the IO controller fail, the fieldbus coupler signals
termination of the application relationship with an RTA alarm after a specific time
(T) with the reason "DataHoldTimer expired".
The time (T) is determined as follows:
T = („DataHoldFactor“ + 1) * send cycle time
