The PPCR221 runs CoDeSys 2.3. Any "Fault Code" shown on an HMI is almost certainly a custom variable (e.g., fault_code := 1234 ). You need the PLC project source code or a fault list exported from the program . These are the most severe faults, often requiring
| Hex Code | Description (System) | Action | | :--- | :--- | :--- | | 16#0001 | Watchdog overflow | Increase task cycle time or optimize code. | | 16#2001 | No user program | Download project. | | 16#3002 | I/O bus failure (K-Bus/E-Bus) | Check terminal bus coupler, power supply. | | 16#4003 | Retain data corrupted | Clear retain memory and reload defaults. | | 16#5005 | Sercos ring error | Check fiber optic cables, ring configuration. | | 16#6xxx (e.g., 0x6A01) | PROFIBUS DP: Station not found | Check address switch, cable termination. | Any "Fault Code" shown on an HMI is
If a critical internal fault occurs, you may need to power down the 24V supply to the module, wait 10 seconds, and power it back up.
