介绍了一个使用VisualC++的Socket与OMRONPLC之间的通信程序,并成功地应用在自动控制系统中,主要实现上位机与OMRONPLC之间的以太网通信,并对它们之间的通信协议作了描述,文中所介绍的通信程序的设计方法具有一定参考价值。
A communication program between Socket and OMRONPLC using Visual C ++ is introduced and successfully applied in the automatic control system. Ethernet communication between the host computer and OMRON PLC is mainly realized and the communication protocol between them is described. The communication method introduced in this paper has certain reference value.
