Panel & PLC Error Codes
The C-more Micro-Graphic panel includes built-in PLC communication protocol diagnostics
that monitor the exchange of data between the panel and the PLC. The diagnostics look for the
proper exchange of data, correct handshaking signals, addressing errors, incorrect data bytes,
wrong packet format, etc. The diagnostics also monitor and display any of the errors that the
designated PLC generates if there is a problem with the PLC’s communications. The PLC
generated errors are interpreted by the C-more Micro-Graphic programming software and are
displayed across the top of the panel’s display embedded as a hexadecimal value in error code
P499.
If a C-more Micro-Graphic communication error does occur, the error message will be displayed
in the upper left of the panel’s display screen along with the error code number. The error code
with error message will blink off and on.
NOTE: See Appendix A: Panel & PLC Error Code Tables for a complete list of all error codes.
