9.4.1 Operation Errors
If an operation error occurs, one of the following may be the cause.
• An incorrect operation was executed in a ladder program.
• An incorrect operation was executed in a motion program.
• An incorrect operation was executed in a sequence program.
If an operation error occurs, use the following procedure to identify the instruction that caused the operation error.
1.
Identifying the drawing type and error details by checking SW00080 to SW00089.
The operation error details are stored in the following system registers according to the type of drawing in which
the operation error occurred. For motion programs, the details are stored in the system registers for DWG.H.
Example: SW00085 is a Value Other Than 0000H
This indicates that an operation error occurred in the high-speed scan. In that case, if SW00084 is continuously
incremented, it means that the instruction with the operation error has been executed continuously.
2. Identifying the drawing number by checking SW00122, SW00138, SW00154, and SW00186
3. Identifying the instruction causing the error in the drawing
There are different methods to identify operation errors for integer operations and real-number operations. To
identify operation errors using integer operations, refer to Troubleshooting Procedure Example 1.
To identify operation errors using real-number operations, refer to Troubleshooting Procedure Example 2.
