This function shows the PWM output state. The PWM output flag shows the output status under the CH special I/O state under the system variable (#L_ExIOSpCtrl). If the flag is ON, the output is ON. The watch bit will differ, depending on the CH to which you allocate the PWM output.
#L_ExIOSpCtrl
If the start bit of the CH (0 bit) is 1, the output is ON. If it is 0, the output is OFF.
