Monitoring the Fieldbus channels
The Fieldbus channels are monitored for timeout. Timeout and all Modbus errors are
registered as ‘Communication Host (S9)’ event messages.
In the terms of this monitoring strategy, EasyServe is not considered to be a Fieldbus client.
The special settings in the relevant parameter block apply for EasyServe and also the same
rules with regard to logging on and off apply as with a serial coupling.
