he CPU memoryA system power supply PS or load power supply PM has failed.
The R/H redundant system is in the RUN-Solo system state.
Requirement
Read the information in the section Checking before replacing components (Page 257).
Procedure
Proceed as follows to replace a defective system power supply PS or load power supply PM:
1. Switch off the mains supply (24 V DC or 230 V AC).
2. Replace the defective system power supply PS or load power supply PM.
3. Switch the mains supply back on.
4. Switch on the replaced system power supply PS or load power supply PM.
Result
1. The CPU with the replaced system power supply PS or load power supply PM runs
SYNCUP. Requirement: The CPU mode selector is in RUN.
2. The CPU switches to the RUN-Redundant operating state and operates as backup CPU.
The redundant system is in the RUN-Redundant system state againA PROFINET device (IO device/switch) in the PROFINET ring has failed, for example
because of a defect in the IO device or failure of the power supply. The PROFINET ring has
been interrupted. The MAINT LEDs on both CPUs are yellow. The ERROR LEDs on both
CPUs are flashing red.
The R/H redundant system is in the RUN-Redundant system state.
Note
If a switch/IO device fails, the R/H redundant system has no access to the
downstream devices in the connected line topology.
Procedure
Proceed as follows to replace a defective PROFINET device:
1. Locate the faulty PROFINET device.
2. Switch off the supply voltage for the PROFINET device.
3. Disconnect the supply voltage.
4. Disconnect the PROFINET cables from the ports of the PROFINET device.
5. Replace the PROFINET device.
6. Connect the PROFINET cables to the ports of the PROFINET device.
7. Connect the supply voltage to the PROFINET device.
8. Switch the supply voltage back on.
Note
Setting the media redundancy role Client for the PROFINET devices
If you replace a PROFINET device in the PROFINET ring, you need to assign the media
redundancy role "Client" to the PROFINET device in STEP 7. The Client media redundancy
role setting is important for devices that are not IO devices with system redundancy S2 (for
example CPUs and switches). PROFINET devices without system redundancy S2
are not assigned parameters by the R/H-CPUs.
Replaced IO devices with system redundancy S2 are automatically configured by the R/H
system and are reset to the correct settings.
Result
The PROFINET ring has been closed again. The PROFINET device can be accessed again
in the R/H redundant system. The MAINT and ERROR LEDs on both CPUs are off
