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.

Step 2: Modify the hardware configuration offline
Starting situation
The fault-tolerant system is operating in redundant system mode.
Procedure
1. Perform all the modifications to the hardware configuration relating to the added hardware
offline. Assign appropriate icons to the new channels to be used.
2. Compile the new hardware configuration, but do
not
load it into the target system just yet.
Result
The modified hardware configuration is in the PG/ES. The target system continues operation
with the old configuration in redundant system mode.
Configuring connections
The interconnections with added CPs must be configured on both connection partners
after
you complete the HW modification.
