ABB PFSK142 3BSE006505R1 Bus Adaptation Board

ABB PFSK142 3BSE006505R1 To achieve resource sharing through the bus network, in addition to the perfect hardware environment, it is also necessary to develop the corresponding communication programme to match. Communication programme design is divided into two parts: one is the communication programme design of the microcontroller, and the other is the communication programme design of the PC. The microcontroller communication programme is a source programme written in assembly language.

The main function of ABB PFSK142 3BSE006505R1 is to poll each PC in order to receive the on-line application from the PC and to send the on-line permission signal according to the content of the application.The PC communication program is designed by applying the ready-made programming software, and its main function is to send the on-line application and to receive the on-line permission signal.

The hardware design of the ABB PFSK142 3BSE006505R1 bus network is to design bus adaptation circuits capable of resource sharing and allocation management. The bus adapter circuit consists of two parts of the circuit, one is the microcontroller polling circuit and the other is the resource sharing circuit. The main work to be done by the bus adapter circuit is: the polling method is used by the AT89C51 microcontroller as the control station.
