By using the system protocol and network adapter provided by the PLC developer,the interconnection and communication between the PLC and the PC are realized.However,because its communication protocol is not public,the interconnection communication must use the upper computer configuration software provided by the PLC developer,and use peripherals that support the corresponding protocol.It can be said that this method is tailor-made by PLC developers for their own products,so it is difficult to meet the needs of different users.

通过使用PLC开发商提供的系统协议和网络适配器，来实现PLC与PC机的互联通信。但是由于其通信协议是不公开的，因此互联通信必须使用PLC开发商提供的上位机组态软件，并采用支持相应协议的外设。可以说这种方式是PLC开发商为自己的产品量身定作的，因此难以满足不同用户的需求。
