Configuration
The figure below shows a sample structure of a system-redundant controller with
3 converters.
Figure 6-41 System redundancy with converters
Configuring
Configuring the redundancy takes place in STEP 7. In the converter, you only have to
configure the communication via PROFINET.
System redundancy does not depend on the topology of the system.
Diagnostics LEDs
Diagnostics states are shown as follows using LEDs with PROFINET system redundancy:
Color State Significance
Green Continuous light 2 redundancy connections available and setpoints are OK.
Green Flashing light Only one redundancy connection is available or setpoints are missing.
Red Flashing light 2 Hz No connection or setpoint failure (F01910).
