Configuration
9.2 Configuring R/H CPUs
S7-1500R/H redundant system
290 System Manual, 01/2024, A5E41814787-AF
Result: STEP 7 automatically creates both 1515R-2 PN CPUs for the redundant system. STEP 7
displays both CPUs in the network view graphically.
Deleting CPUs from the hardware configuration
You can only delete the two CPUs as a pair.
Figure 9-1 Display of CPUs in the network view
1. Open the CPUs in the device view. In the device view, the first CPU and the second CPU are
each in slot 1.
2. Give the CPUs unique names under Properties.
2. Assigning IP addresses (device IP addresses)
STEP 7 automatically assigns an IP address to each PROFINET interface of a CPU. You can also
assign the IP addresses manually.
For PROFINET interface X1 of the CPUs, the IP addresses must be located in the same subnet.
The IP address is displayed in the CPU properties, in the "PROFINET interface [X1]" area of the
"IP protocol" section.
