| Abstract: | Macroscopic function of protocol is a kind of serial communication mode of OMRON PLC. macroscopic function of protocol can be used in the communication between PLC and the equipments that have RS232C or RS422/485 serial port. Principles of macroscopic function of protocol communication were introduced briefly in this paper. Macroscopic function of protocol communication mode and programmer between a PLC and two frequency converters are given. |
