This function shows the error status of pulse outputs such as in the output pulse frequency and output pulse shot. If the system variable #L_IOStatus[1] has the error code 101 or 103, you can acknowledge the error status from the system variable #L_ExIOSpParmErr. The watch bit will differ, depending on the CH to which you allocate the pulse output.
When changing Special I/O parameters, and the defined value is outside the valid range, operations continue by using parameters set up to that point.
However, since an invalid value is stored in the system, make sure you change it to a valid value.
If you restart the LT with invalid values (go off-line, reset, or turn the power OFF), operations will use initial parameter values set up in GP-Pro EX.
