Parameter F_CRC_Length Does Not Match Generated Values (V2 CPU)

Was bedeutet 42 ?

Parameter "F_CRC_Length" does not match the generated values in an AC500 V2 non-safety CPU PM5xx system. This indicates a misconfiguration in the CRC length parameter for PROFIsafe communication, leading to data integrity errors.

• The CRC length value in parameter F_CRC_Length does not match the actual data length being transmitted.
• Data corruption during transmission.
• Incorrect calculation of Cyclic Redundancy Check (CRC).
• Configuration mismatch between sender and receiver for CRC calculation.
