18.4 Updating the Firmware
18.4.1 Updating Firmware in Modules and Submodules Online
As of STEP 7 V5.1 Service Pack 3, you can update modules or submodules on a station in a
standardized way online. To do so, proceed as described below:
Concept
To update the firmware on a module (CPU, IM, etc.) or a submodule (DI, DO, etc.), you can
download the files (*.UPD) containing the latest firmware on the Internet
("http://www.siemens.com/automation/support").
Select one of these files and download it to the module (PLC Menu).
Prerequisites
The module in the station or module whose firmware is to be updated must be available online.
This means that the programming device (PG) is connected to the same MPI PROFIBUS or
Ethernet as the module whose firmware is to be updated. The firmware can also be updated when
the programming device (PG) is connected to the MPI interface of the DP master CPU and the
module whose firmware is to be updated is connected at the PROFIBUS of the DP interface or the
Ethernet of the PN interface. The CPU must support S7 routing between the MPI interface and the
DP interface or between the MPI interface and the PN interface.
The module or submodule itself must support Firmware updates.
