Updating the firmware
Information about carrying out the firmware update is provided in the ET 200SP System
Manual.
Note
Firmware update
Note that a firmware update can only be performed in STOP mode. If you initiate the update
via TIA Portal, you have to switch the CPU manually to STOP. No dialog prompting you to
do so appears in this case. If the CPU is not switched to STOP, the update is not executed
and the progress bar remains at "0%" and aborts without additional error messages.
Note
Duration of the firmware update
Note that a firmware update can take up to several hours. During the first 10 minutes of a
firmware update, a progress of "0%" is displayed via TIA Portal. While the update is already
in progress during this time, the progress is less than "4%".
A red flashing DIAG LED indicates that the update is in progress.
At the end of each successful firmware update, the firmware of the TM ECC PL ST runs
internal procedures. At the same time, TIA Portal retrieves the module status to confirm the
successful update. However, the module only answers this query after it has fully processed
its internal procedures. You cannot operate TIA Portal until it has received all the information
it has requested.
NOTICE
Supply voltage during the firmware update
The supply voltage of the ET 200SP station as well as the external voltage supply when the
Base Unit B1 is used, or the voltage supply of the supplying potential module when the
Base Unit B0 is used, must not be switched off during a firmware update.
The flashing "EN-LED" indicates that the firmware update was installed without any errors.
You can now disconnect the device from the supply voltage.
Non-observance results in a functionless state of the TM ECC PL ST module that cannot
be remedied.
