Product overview
3.3 Firmware update
LED behavior after a successfully completed firmware update
When the TIA Portal is used, an error-free firmware update is indicated by the message that
the firmware was successfully transferred.
Note
Confirming a message after an error-free firmware update
You must confirm the message using the button before you continue. Without confirmation,
the LED status remains unchanged so that the firmware update is incomplete and must be
repeated.
When
changes autonomously.
If the firmware is updated without errors, the LED status is updated:
● DIAG flashes red until the AS-i voltage is switched off and back on again
● PWR is lit green
● Remaining AS-i LEDs are lit
Required intermediate step for firmware update of a CM AS-i Master ST with FW V1.0
using an ET 200SP CPU.
Failure to perform this step causes the CM AS-i Master ST to become permanently
inoperable.
If you want to perform an update to a higher firmware version for a CM AS-i Master ST
module with FW V1.0 and are using an ET 200SP configuration with an ET 200SP CPU in
place of an interface module (IM), you must always perform the following intermediate step:
After the update of the LED status, the CM AS-i master ST module must be removed from
the ET 200SP BaseUnit. Instead of removing the module, it is also sufficient to switch off
the AS-i voltage and the 24 V voltage of the ET 200SP. A TIA Portal error message
appears approximately one minute after the module has been removed indicating that
online access to the module is no longer possible. Confirm the error message. Then plug
the module onto the BaseUnit again or switch the voltages back on.
Now repeat the firmware update. In this case, the intermediate step described here can be
skipped.
The intermediate step is not required for:
• Firmware update of a CM AS-i Master ST module with active FW V1.1 or higher
• Use of an ET 200SP configuration with a PROFINET interface module (IM) and
• Use of an ET 200SP configuration with a PROFIBUS interface module (IM) and
