摘　　要：介绍了GE90-30PLC与监控计算机无法建立联系时,以CPU364型组态的PLC,利用CPU364的RS-422串口与监控计算机的RS-232串口用硬件物理连接,结合Versa Pro编程软件实现通信的技术方法。An introduction was made on the technical application of communication between GE90-30PLC anti su- pervision/control computer. When a GE90-30PLC equipped with CPU364 fails to communicate with the supervi- sion/control computer, the RS-422 serial port of CPU364 may be connected with the RS-232 port of computer. Hanlware physical connection combined with programming by VersaPro software will permit the communication.
