Step 7: Modify hardware
Starting situation
The fault-tolerant system is operating with the new hardware configuration in redundant
system mode.
Procedure
1. Disconnect all the sensors and actuators from the components you want to remove.
2. Unplug modules of the one-sided I/Os that are no longer required from the racks.
3. Unplug components that are no longer required from the modular DP stations.
4. Remove DP stations that are no longer required from the DP master systems.
Note
With switched I/O: Always complete all changes on one
segment of the redundant DP
master system before you modify the next segment.
Result
The removal of non-configured modules does not influence the user program. The same
applies to removing DP stations.
The fault-tolerant system continues to operate in redundant system mode.
