PLC and SLC Error Codes (.ERR)

Logix firmware revision 10.x and later provides new error codes for errors that are associated with PLC and SLC™ message types (PCCC messages).

This change lets RSLogix 5000 software display a more meaningful description for many of the errors. Previously the software did not give a description for any of the errors associated with the 00F0 error code.

The change also makes the error codes more consistent with errors returned by other controllers, such as PLC-5® controllers.

The table shows the change in the error codes from R9.x and earlier to R10.x and later. As a result of the change, the .ERR member returns a unique value for each PCCC error. The .EXERR is no longer required for these errors.
