9.2 Firmware update
Introduction
During operation, it can become necessary to update the firmware (e.g. for function
extensions).
Firmware updates are used to update the firmware of the interface module and I/O modules.
Note
Temporary bus interruption
When you perform a firmware update of an ET 200AL I/O module, then the ET-Connection is
temporarily interrupted due to the restart of I/O module. All downstream ET 200AL I/O
modules report a pull/plug interrupt.
Options for the firmware update
You have the following options to running a firmware update:
• Online via STEP 7, as of V5.5
• Online with STEP 7, TIA Portal V13 or higher
• Embedded web server running on a SIMATIC CPU or a SIMATIC F-CPU with fail-safe
modules.
• SIMATIC Automation Tool (SAT)
Not for use with fail-safe ET 200AL I/O modules
