Chapter 12 Error Code List and Special Internal Outputs

12.3 Operation Error Codes

If an error occurs when a control instruction is executed, “1” is set in the operation error (ERR) special internal output “R7F3” and an error code (hexadecimal) indicating the description of the error is set in WRF015.

To clear the operation errors to zeros, execute “R7F3=0” using a forced setting from a program or peripheral unit. To clear the error codes to zeros, execute “WRF015=0” using a forced setting from a program or peripheral unit.
