Why does my CAN safety sensor stop sending SRDO messages after restoring default parameters using Object 1011?
Last Updated 5 months ago
Object 1011 is used to restore a CAN safety sensor's parameters to their factory defaults. After performing this reset, you may notice that the sensor stops sending SRDO (Safety-Related Data Object) messages and appears unresponsive. This behavior occurs because the restoration process resets essential parameters such as the zero offset, Node ID, and SRDO communication parameters to factory default settings.
Once these parameters are restored, the CRC (Cyclic Redundancy Check) for both SRDO communication and the zero offset must be recalculated and validated. Without recalculating these CRCs, the sensor will not resume normal operation, as it cannot verify the restored settings.
To restore functionality, please follow these steps to update the CRC:
Recalculate the CRC for the SRDO communication parameters.
Recalculate the CRC for the zero offset.
Validate the new CRCs to ensure the sensor operates correctly with the restored settings.
After completing these steps, the sensor should resume normal SRDO communication.
