With IM 153-2 firmware as of V4.x, it is possible to update the firmware of both IMs during
ongoing operation in redundant mode. The update is supported by STEP 7 and has no effect
on the running application. The firmware in a redundant system is updated (directly) from the
programming device / PC via PROFIBUS DP.

● Programming device / PC is connected directly with PROFIBUS DP
● STEP 7 version on the programming device / PC: as of STEP 7 V5.4
● The update file for the firmware update is available on the programming device / PC.
● The H system is error-free and in redundant mode.
