Fieldbus Communication Fault

What does 53 mean?

The data connection between the fieldbus master and the fieldbus board in the drive is defective. This prevents the drive from receiving or sending data via the fieldbus network, disrupting remote control and monitoring. Prolonged communication loss can lead to process control issues.
