Signs of life of the individual stations and diagnostics
The inputs and outputs message type is used as a “sign of
life” recognition to ensure that the state of a station can be
recognised by other stations. The states of the inputs and
outputs are sent cyclically and at the set baud rate,
irrespective of the SEND IO setting. If the inputs and outputs
of a station are not recognised by other stations after a time
determined by the baud rate, the station is deemed to be
disconnected until the next “sign of life” is recognised.
Evaluation occurs at the following intervals:
