The upward connection of the network is an Internet problem,and the downward connection is a field bus problem.In addition,whether the existing network can use the Ethernet”e network to the end”method,the network adopts the client/server method,the browser/server method,the producer/consumer The method,the interface software adopts the OPC method and other issues need to be further implemented.PLC and intelligent MCC motor control center,NC/CNC numerical control equipment supporting numerical control machine tools,and other operation control systems,electronic control equipment,frequency converters and soft starters are connected to form a system;PLC should cooperate with DCS division of labor and act as DCS Remote I/O station,etc.;PLC should cooperate with IPC,in addition to using IPC as human-machine interface,it is also feasible to use I/O components of software PLC;in addition,there are PLC and emergency shutdown safety system(ESD,EmergencyShutDownSystems)The relationship with the three-dimensional warehouse,robot,CAD/CAM,etc.must be handled well.In short,PLC should be compatible with various new technologies,making PLC a”computer”in the true sense.

网络向上连是互联网问题，向下连是现场总线问题，另外现有网络能否用以太网“e网到底”方式、网络采用客户器/服务器方式、浏览器/服务器方式、生产者/消费者方式、接口软件采用OPC方式等问题都有待进一步落实。PLC与智能MCC马达控制中心、与数控机床配套的NC/CNC数控设备，以及与其它运行控制系统、电控设备、变频器和软起动器等连成系统;PLC要与DCS分工合作，充当DCS的远程I/O站等;PLC要与IPC分工合作，除用IPC作人机界面外，作软件PLC的I/O部件也是可行的;此外还有PLC与紧急停车安全系统(ESD，EmergencyShutDownSystems)的关系、与立体仓库、机器人、CAD/CAM等等都要处理好关系。总之，PLC要兼容各种新技术，使PLC成为真正意义上的“电脑”。
