SI Motion: Sensor Module software/hardware incompatible

What does 201673 mean?

The Sensor Module's existing software and/or hardware is not compatible with the higher-level control's safe motion monitoring function. This prevents the safe motion monitoring features from functioning correctly, potentially impacting safety-critical operations. Note that this specific fault does not immediately result in a safety stop response.

• Firmware version of the Sensor Module is incompatible with the safety firmware of the higher-level control unit (e.g., CU320-2, SIMOTION D).
• Hardware revision mismatch between the Sensor Module and the safety control, requiring an upgrade or downgrade.
• Incorrect order number for the Sensor Module for the specific safety application (e.g., safe encoder type).
• Project configuration in TIA Portal or STARTER specifies an incompatible Sensor Module version.

Click steps to track your progress.

1. 1

   Compare the installed firmware version of the Sensor Module with the required version for the safety control unit.

2. 2

   Update the Sensor Module firmware to a compatible version using STARTER or TIA Portal software.

3. 3

   Verify the hardware revision number of the Sensor Module and confirm its compatibility with the overall safety system documentation.

4. 4

   Check the order number (MLFB) of the Sensor Module against the project design specifications.

5. 5

   Re-compile and download the safety program to the control unit after ensuring compatible module versions are configured.
