Step 1: Modify hardware

Starting situation
The fault-tolerant system is operating in redundant system mode.
Procedure
1. Add the new components to the system.
– Plug new central modules into the racks.
– Plug new module into existing modular DP stations
– Add new DP stations to existing DP master systems.
2. Connect the required sensors and actuators to the new components.
Result
The insertion of non-configured modules will have no effect on the user program. The same
applies to adding DP stations.
The fault-tolerant system continues to operate in redundant system mode.
New components are not yet addressed.
