DIAGNOSIS/BEHAVIOR ON ERROR
If the master fails or the bus connection
is interupted (communication error) the
last setpoint remains active and the
KS 94 works independently. If the mas-
ter PLC is switched in stop-mode the
Clear Data Signal will be suppressed and
the last setpoint remains active, too! In
case of a fault on the bus, the KS 94 can
activate an alarm relay.
