Fault codes are alphanumeric codes displayed on the PLC's screen or transmitted to a monitoring system when a fault occurs. These codes serve as a diagnostic tool, allowing users to quickly identify the source of the problem and take corrective action. The Rexroth PPCR221 fault codes are categorized into several groups, each corresponding to a specific type of error or fault.
