| Abstract: | For the problems of data communication in the system of Access Gates, a new multi-host communication system based on CANopen protocol is designed.Firstly, the composition of Access Gates control system based on PIC18F4680 single-chip microcontroller is presented.Secondly,communication ob-ject PDO,SDO and NMT in CANopen protocol are used,so a series of operations including data transmit-ting,instruction sending and value modifying are realized.The experimental result shows the system′s relia-ble stability and rapid information transfer in course of data communication. |
