User Program Execution Error
This error indicates that invalid data is found during execution of a user program. When this error occurs, the ERR LED
and special internal relay M8004 (user program execution error) are also turned on. The detailed information of this error
can be viewed from the error code stored in special data register D8006 (user program execution error code).
