PLC的通讯包含主机与长途I/O接口之间的通讯、多台PLC之间的通讯、PLC与其它智能操控设备之间的通讯。PLC与其它智能操控设备一同，能够构成“集中办理、涣散操控”的分布式操控体系。有必要指出，并不是一切的PLC都有上述悉数功用，有些小型PLC只要上述的有些功用，可是报价较低。
如图5-10所示为定时时间为1h的梯形图及时序图，辅助继电器M1用于定时启停控制，采用两个0.1s定时器T14和T15串级使用。当T14开始定时后，经1800s延时，T14的常开触点闭合，使T15再开始定时，又经1800s的延时，T15的常开触点闭合，Y4线圈接通。从X14接通，到Y4输出，其延时时间为1800s+1800s=3600s=1h
