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:
BF Meaning
(Bus error)
red
○ 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
and the outputs are of the slaves are disabled.
○ CPU is in STOP state, the master is in "operate" state. All the slaves are in
DE. The outputs are enabled.
BB CPU is in RUN state, at least 1 slave is missing and at least 1 slave is in DE.
BB 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)
BB At least 1 slave is missing and no slave is in DE.
BB At least 1 slave is not in DE.
BF Meaning
(Bus error)
red
○ Slave has no project.
● There is a bus error.
○ Slave is in state data exchange with master.
Slave CPU is in STOP state.
○ Slave is in state data exchange with master.
Slave CPU is in RUN state.
