ABB PFEA113-65 Computer Monitoring System

ABB PFEA113-65 will be connected to the PLC and touch screen with RS232C data signal line, after debugging checks, display the current screen is normal, display the set screen is normal, the PLC program is running normally, the only thing is the touch screen GOT930-BWD-C screen for a long time the background light does not go out, in the DU how to adjust the time to turn off the light is also useless, the auxiliary relays M +0 to M +7 has a special purpose, of which M +2, ON, can make the display screen background lights in the specified time after the lights off; and M +6, 0N, said the DU battery is insufficient, in order to make the design more perfect, so in the PLC sequential control ladder licked plus two lines of the program.

ABB PFEA113-65 is widely used to exchange data with PLC devices in the field using a computerized monitoring system. This type of data exchange is often characterized by the following, a large amount of data, scattered collection points, narrow bandwidth. As different manufacturers provide PLC field device communication mechanism is not the same, the computer monitoring system software needs to develop more and more device communication drivers.
