9.4 Troubleshooting Details
9.4.1 Operation Errors
9-8
Troubleshooting Procedure Example 2
This section describes the procedures for troubleshooting if an operation error (0030H: Real-number opera-
tion - invalid operation (non-numeric)) has occurred in DWG.H.
1. Identify the error DWG number from the system register (SW00154), and then open that drawing.
2. Check the value for the real-number operation in the online monitor.
In this example, MF000000 for the DIV instruction is ************.
************ Indicates an incorrect (i.e., non-numeric) value for a real-number value. Executing a real-number
operation using this value will generate an operation error (0030H: Real number operation - invalid operation
(non-numeric)) from the system.
Complement
If an operation error occurs, one of the following may be the cause.
The value has not been set in the registers (undefined data value).
Bit, integer, and double-length integer operations are executed for a register that has overlapping addresses.
If a real number operation is executed, the real-number value must always be set in advance.
3. Repeat step 2 to identify the register that is causing the operation error.
