6.8 Assigning IO device to the redundant S7-1500R/H system
Requirements
• Redundant S7-1500R/H system
• IO device:
– As of firmware version V2.8, the redundant S7-1500R/H system supports IO devices
with system redundancy S2 and standard IO devices.
– The redundant S7-1500R/H system with firmware version before V2.8 only supports
IO devices with system redundancy S2, e.g. IM 155-6 PN HF as of firmware version
V4.2.
Procedure
To assign an IO device to the redundant S7-1500R/H system, follow these steps:
1.
In the network view of STEP 7, select the PROFINET interface of the IO device.
2. Using drag-and-drop, draw a line between the PROFINET interface of the IO device and the
PROFINET interface X1 of the left CPU.
Figure 6-10 Assigning IO device to the left CPU
The IO device is assigned to the left CPU.
3. Using drag-and-drop, draw a line between the PROFINET interface of the IO device and the
PROFINET interface X1 of the right CPU.
