Overview

Timeout
monitoring

Timeout monitoring can be activated in the event that recorder is run as slave
via Ethernet.

If active monitoring is the case then the communication between the slave (pa-
perless recorder) and the master with regard to the external analog and binary
inputs is monitored. If no communication takes place within the configured
time then an alarm message is displayed and entered into the alarm and event
list.

Timeout monitoring remains inactive after the recorder has been switched on
until the master sends the first query. That way, different switch-on and start-
ing times from the master and slave are compensated.
