SIGMA CONTROL 2 monitors the bus communication at log level (SIGMA CONTROL 2). 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.
