Read/write
0x0258 (600 decimal)
This is the maximum number of milliseconds the fieldbus coupler will allow a
MODBUS/TCP connection to stay open without receiving a MODBUS request.
Upon time-out, idle connection will be closed. Outputs remain in last state.
Default value is 600 ms (60 seconds), the time base is 100 ms, the minimal value
is 100 ms. If the value is set to '0', the timeout is disabled. On this connection, the
watchdog is triggered with a request.
