CAN-IN1 Sync Communication Error

What does ce1 mean?

A communication error has occurred on CAN-IN1 during synchronous control, indicating that faulty data is being received or the communication itself is interrupted. This can be caused by loose bus module connections or issues with the transmitting device. Loss of synchronous communication can lead to unsynchronized operation or system shutdown.
