An introduction was made on the technical application of communication between GE90-30PLC and 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. Hardware physical connection combined with programming by VersaPro software will permit the communication.
