2. Creating R1 devices
In the example, you add two R1 devices with system redundancy R1 to the H-CPUs. To do so,
proceed as follows:
1. Switch to the network view.
2. Drag an ET 200SP IM 155-6 PN R1 from the hardware catalog into the working window.
3. Switch to the device view of the ET 200SP IM 155-6 PN R1.
4. Drag the desired I/O modules and the server module to the respective slots of the ET 200SP
IM 155-6 PN R1.
5. Repeat steps 1 to 4 for the second ET 200SP IM 155-6 PN R1.
Result: The R1 devices are created and the modules are assigned.
