RS Format Error

Was bedeutet RS 02 ?

This serial communication error indicates that the transmitted information contains more characters than allowed, or a Carriage Return/Line Feed (CR/LF) sequence is missing at the end of the transmission. This signifies an incorrect overall message structure.

• The serial command string exceeds the maximum allowed character length.
• Missing or incorrectly placed Carriage Return (CR) and Line Feed (LF) characters at the end of the transmitted message.
• Mismatch between the sending device's and CLM01.3-M's serial communication protocol expectations.
• Corrupted data during transmission, leading to an apparent format error.

1. 1

   Verify that the transmitted information adheres to the specified format, including character count and the mandatory CR/LF sequence, as detailed in Chapter 7 (Serial Interface).

2. 2

   Ensure the serial communication settings (baud rate, parity, word length, stop bits) on both the sending device and CLM01.3-M (Parameters 80 and 81) are identical.

3. 3

   Check the serial cable for proper wiring (e.g., RX/TX, ground, handshaking if used) and adequate shielding.

4. 4

   Re-transmit the command after confirming the message structure and termination characters.

5. 5

   Use a serial terminal program to monitor the exact byte sequence being sent to the CLM01.3-M for debugging.
