通讯及联网
PLC通讯含PLC间的通讯及PLC与其它智能设备间的通讯。随着计算机操控的开展，工厂自动化网络开展得很快，各PLC厂商都十分重视PLC的通讯功用，纷繁推出各自的网络体系。新近出产的PLC都具有通讯接口，通讯十分便利。
PLC常用程序规划言语: 
在可编程操控器中有多种程序规划言语,它们是梯形图言语、布尔助记符言语、功用表图言语、功用模块图言语及结构化句子描绘言语等。梯形图言语和布尔助记符言语是根本程序规划言语，它通常由一系列指令构成，用这些指令能够完结大多数简略的操控功用，例如，替代继电器、计数器、计时器完结次第操控和逻辑操控等，经过拓展或增强指令集，它们也能履行其它的根本操作。功用表图言语和句子描绘言语是高档的程序规划言语，它可依据需求去履行更有用的操作，例如，模拟量的操控，数据的操作，报表的报印和别的根本程序规划言语无法完结的功用。功用模块图言语选用功用模块图的办法，经过软衔接的办法完结所请求的操控功用，它不仅在可编程序操控器中得到了广泛的运用，在集散操控体系的编程和组态时也常常被选用，因为它具有衔接便利、操作简略、易于把握等特色，为广阔工程规划和运用人员所喜欢。 
依据可编程器运用规划，程序规划言语能够组合运用，常用的程序规划言语是：梯形图程序规划言语 、 布尔助记符程序规划言语（句子表）、功用表图程序规划言语 、功用模块图程序规划言语、 结构化句子描绘程序规划言语、 梯形图与结构化句子描绘程序规划言语、 布尔助记符与功用表图程序规划言语、 布尔助记符与结构化句子描绘程序规划言语。
