C-more panel Communication Error Codes
Below are a list of C-more panel error codes. If a C-more communications error occurs, the error message displays at the top of the screen.
| Note: | The PLC generates the following errors, the C-more panel monitors them, and the panel screen displays them as a four-digit hexadecimal value in a Panel Error Code PLC-499 message. Refer to the PLC manufacturer documentation for additional information. |
For PLC-specific error codes, use this table or use the C-More5 Error Code Lookup Tool.
