SIGMA CONTROL 2 monitors the bus communication at log level (Modbus TCP). If there is a
check box behind Communication error , this monitoring in the Send mode can be switched off by
deactivating the check box.
In Send/Receive or Master modes, SIGMA CONTROL 2 can monitor: Com-Module the bus com‐
munication at user level. For this purpose, the bus master reads a value ("toggle bit") that changes
with every bus cycle and returns it without change. SIGMA CONTROL 2 returns a bus alarm if the
bit does not change for a time longer than set ( Timeout ). Activate the check box to enable monitor‐
ing.
