PLC networking and communication capabilities are very strong,and new networking structures are constantly being introduced.

PLC can be connected with a personal computer for communication,and a computer can be used to participate in programming and management of PLC control,making PLC more convenient to use.

In order to give full play to the role of the computer,one computer can control and manage multiple PLCs,up to 32.One PLC can also communicate with two or more computers to exchange information to monitor the PLC control system in multiple places.

PLC and PLC can also communicate.One-to-one PLC communication is possible.Can communicate with several PLCs.Can be as many as tens or hundreds.

PLC and intelligent instruments and intelligent execution devices(such as frequency converters)can also communicate with each other,exchange data and operate each other.It can be connected into a remote control system,and the system range can be as large as 10 kilometers or more.

It can form a local network,not only PLC,but also high-end computers and various intelligent devices can enter the network.The bus network can be used,and the ring network can also be used.The net can also be set.Networks can also be bridged.Networking can organize thousands of PLCs,computers,and intelligent devices in a network.

PLC联网、通讯能力很强，不断有新的联网的结构推出。

PLC可与个人计算机相连接进行通讯，可用计算机参与编程及对PLC进行控制的管理，使PLC用起来更方便。

为了充分发挥计算机的作用，可实行一台计算机控制与管理多台PLC，多的可达32台。也可一台PLC与两台或更多的计算机通讯，交换信息，以实现多地对PLC控制系统的监控。

PLC与PLC也可通讯。可一对一PLC通讯。可几个PLC通讯。可多到几十、几百。

PLC与智能仪表、智能执行装置（如变频器），也可联网通讯，交换数据，相互操作。可联接成远程控制系统，系统范围面可大到10公里或更大。

可组成局部网，不仅PLC，而且高档计算机、各种智能装置也都可进网。可用总线网，也可用环形网。网还可套网。网与网还可桥接。联网可把成千上万的PLC、计算机、智能装置组织在一个网中。
