The firmware of the ASM 456 can be updated via PROFIBUS. You have several options for
updating the firmware:
● With STEP 7 Classic
● With STEP 7 Basic / Professional (TIA Portal)
Firmware update with connected RF680R/RF685R readers
Note that when the RF680R/RF685R are connected to the ASM 456, the firmware update of
the readers must be performed via the WBM of the readers. You can start the WBM from the
The ASM is connected to PROFIBUS with functional DP communication (basic
communication only, no application required). The firmware update can be made regardless
of whether an application is running.
If the firmware update is performed while an application is running, this can slow down the
update and command execution.
Make sure that the required update files (*.upd) are stored locally.
