Process Data Length Mismatch

Was bedeutet 7 pulses (arg 0) ?

The K-bus ERR LED flashes 7 times, with '0' in the argument sequence, indicating a discrepancy where the process data lengths of the set configuration and the actual configuration do not correspond. This means the TwinCAT configuration does not match the physical Bus Terminal setup.

• Process data input/output length mismatch between controller and bus terminals.
• Configuration error in the size of process data.
• Faulty bus terminal sending incorrect data length.
• Mismatch in the defined PDO (Process Data Object) configuration.

   Check the TwinCAT configuration of the K-bus, verifying that the configured types and number of Bus Terminals are consistent with the physically installed hardware. Pay attention to process data sizes defined for each terminal.
