PLC具有通信联网的功能，它使PLC与PLC之间、PLC与上位计算机以及其他智能设备之间能够交换信息，形成一个统一的整体，实现分散集中控制。现在几乎所有的PLC新产品都有通信联网功能，它和计算机一样具有RS-232接口，通过双绞线、同轴电缆或光缆，可以在几公里甚至几十公里的范围内交换信息。


PLC之间的通讯网络是各厂家的，PLC与计算机之间的通讯，一些生产厂家采用工业标准总线，并向标准通讯协议靠拢，这将使不同机型的PLC之间、PLC与计算机之间可以方便地进行通讯与联网。


了解了PLC的基本结构，我们在购买程控器时就有了一个基本配置的概念，做到既经济又合理，尽可能发挥PLC所提供的佳功能。


基本指令系统特点


PLC的编程语言与一般计算机语言相比，具有明显的特点，它既不同于语言，也不同与一般的汇编语言，它既要满足易于编写，又要满足易于调试的要求。目前，还没有一种对各厂家产品都能兼容的编程语言。如三菱公司的产品有它自己的编程语言，OMRON公司的产品也有它自己的语言。但不管什么型号的PLC，其编程语言都具有以下特点：
