RS Checksum Error

Was bedeutet RS 04 ?

This serial communication error occurs when the checksum calculated by the CLM01.3-M from received data does not match the checksum transmitted by the sending device. This indicates data corruption during transmission, if checksum is enabled.

• Data corruption or loss during serial transmission between the sending device and the CLM01.3-M.
• Checksum calculation error on the sending device, resulting in an incorrect transmitted checksum.
• Parameter 81 (Serial Interface Functions) is configured incorrectly for checksum (e.g., checksum enabled on one side, disabled on the other).
• Noise or interference on the serial communication line.

1. 1

   Verify that the checksum being transmitted by the sending device is calculated correctly as per Chapter 7 (Serial Interface).

2. 2

   Ensure that Parameter 81 (Serial Interface Functions) on the CLM01.3-M is configured to match the checksum setting (enabled/disabled) of the sending device.

3. 3

   Re-transmit the information after confirming checksum calculation and settings.

4. 4

   Inspect the serial communication cable for damage, proper shielding, and correct connections.

5. 5

   If possible, use diagnostic tools to monitor the serial data stream and verify checksum integrity at different points in the communication path.
