The redundancy of T9402  devices ensures that when one of the sites fails, the PLC can read the correct process data from the backup I/O device site, which means that the I/O site needs to be configured twice on the hardware.

T9402  simultaneously reads input process data from two I/O device stations, which are called PRIMARY-I/O-Station and BackUP-I/O – Station, respectively. In the control program, a selection function is used to determine which sub station’s input data is selected based on the connection status of the logical communication. For outputting process data, it is relatively simple as the output T9402  is always written to two I/O sub stations simultaneously. The status variables of the PROFINET IO device are periodically sent to the PLC, and the PLC can know the working status of the IO device through the status variables.
