The corresponding Ethernet PG/OP channel is physically connected to the Ethernet.
The corresponding Ethernet PG/OP channel is not physically connected to the Ethernet.
The corresponding Ethernet PG/OP channel indicates Ethernet activity, here the LED flickers.

Dependent on the mode of operation the LEDs show information about the state of oper-
ation of the PROFIBUS part according to the following pattern:
Description
Master has no project, this means the interface is deactivated respectively the master configured without
slaves with no errors.
CPU is in STOP state, the master is in "clear" state. All the slaves are in DE (data exchange) and the
outputs of the slaves are disabled.
CPU is in RUN state, the master is in "operate" state. All the slaves are in DE. The outputs are enabled.
CPU is in RUN state, at least 1 slave is missing and at least 1 slave is in DE.
CPU is in STOP state, the master is in "clear" state. At least 1 slave is missing and at least 1 slave is in
DE.
PROFIBUS is interrupted (no communication possible).
At least 1 slave is missing and no slave is in DE.
At least 1 slave is not in DE.
Slave has no configuration.
There is a bus error.
Slave exchanges data with the master.
Slave CPU is in state STOP.
Slave exchanges data with the master.
Slave CPU is in state RUN.
