Timeout monitoring, timeout
This function monitors the communication between the Modbus master and Modbus slave from the per-
spective of the Modbus slave. After enabling timeout monitoring, a timer starts when the first request is
received (the timer time is the time set as the "Timeout"). The timer starts to run again after each new
request. If the request does not appear, an internal digital signal is activated after the timer has elapsed
and an entry is made in the alarm and event list. The signal is reset with the next request.
