AH500 Quick Start After the system is tested, users have to cancel the setting so that the CPU module can return to normal. Monitoring the device When the logical control is tested, the devices which have to be modified may be used in different programs. It is not convenient to find these devices in the programs and monitor them. Besides, users sometimes do not alter the value in a device for debugging. They alter the value for testing the external device. If users want to alter the value in a device by means of monitoring the program, they will have difficulty in finding the device, and the program has to be uploaded from the CPU module to the computer.
