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.
Note
With switched I/O: Always complete all changes on one segment of the redundant DP
master system before you modify the next segment.
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.
