Invalid CRC

Hva betyr xxxx 0100 ?

A Cyclic Redundancy Check (CRC) error was detected in an FSoE telegram. This indicates data corruption during transmission, usually due to noise, damaged cabling, or faulty network components. It compromises safety integrity and prevents reliable communication, forcing a safe state.

• Cyclic Redundancy Check (CRC) error detected.
• Data corruption during transmission.
• Faulty communication cable or connector.
• Electromagnetic interference corrupting data.
• Incorrect CRC calculation on sender or receiver side.

1. 1

   Inspect all Ethernet cabling and connectors between FSoE devices for damage, proper shielding, and secure connections.

2. 2

   Check for strong electromagnetic interference (EMI) sources near the communication cables.

3. 3

   Verify network switches or couplers in the FSoE path are suitable for industrial Ethernet and functioning correctly.

4. 4

   Perform a cable test to measure signal integrity and identify faulty segments.
