Ethernet PG/OP channel
L/A
(Link/Activity)
green
S
(Speed)
green
Meaning
X
The Ethernet PG/OP channel is physically connected to Ethernet.
X
There is no physical connection.
flickers
X
Shows Ethernet activity.
The Ethernet interface of the Ethernet PG/OP channel has a transfer rate
of 100Mbit.
The Ethernet interface of the Ethernet PG/OP channel has a transfer rate
of 10Mbit.

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:
Master operation
RN
(RUN)
green
ER
(ERR)
red
DE
green
IF
red
Meaning
Master has no project, this means the interface is deactivated
respectively PtP is active.
Master has bus parameters and is in RUN without slaves.
2Hz
Master is in "clear" state (safety state). The inputs of the slaves
may be read. The outputs are disabled.
Master is in "operate" state, this means data exchange between
master and slaves. The outputs may be accessed.
CPU is in RUN state, at least 1 slave is missing.
2Hz
CPU is in STOP, at least 1 slave is missing.
Initialization error at faulty parametrization.
Wait state for start command from CPU.
Slave operation
RN
(RUN)
green
ER
(ERR)
red
DE
green
IF
red
Meaning
Slave has no configuration respectively PtP is active.
2Hz
Slave is without master.
