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 This could be due to outdated firmware or an unsuitable hardware version that does not support the required safety features. While this fault does not immediately trigger a safety stop, it prevents the safe motion monitoring features from functioning correctly, potentially compromising machine safety if not upgraded.

• Sensor Module firmware version is older than required by the safe motion control unit's (CU) minimum version (e.g., incompatible with CU firmware V5.2).
• Incorrect hardware variant of the Sensor Module installed (e.g., 6SL3055-0AA00-5BA0 instead of 6SL3055-0AA00-5CA0) not supported by the safety configuration.
• Configuration data loaded into the Sensor Module does not match the higher-level safe motion project, indicating a mismatch in parameters.
• Communication profile mismatch between the Sensor Module and the Safety Control Unit (e.g., PROFIsafe version incompatibility or address conflict).
• Hardware defect within the Sensor Module preventing proper identification or communication with the safety system.

Click steps to track your progress.

1. 1

   Connect to the drive system via STARTER/Tia Portal and read out the firmware version of the Sensor Module (r0018[x]).

2. 2

   Compare the Sensor Module's reported firmware version to the compatibility matrix in the system's function manual for the Safety CU.

3. 3

   Update the Sensor Module firmware to the compatible version using the engineering software (e.g., 'Firmware update' function in STARTER).

4. 4

   Verify the Sensor Module part number (e.g., 6SL3XXX-XXXXX-XXXX) matches the bill of materials for the safe motion system.

5. 5

   Upload the current safe motion project configuration from the Safety CU and re-download it to the Sensor Module after a device reset (e.g., p0970=1).
