我们提供更多知识
（1）控制逻辑——继电器控制逻辑采用硬接线逻辑，利用继电器机械触点的串联或并联，及时间继电器等组合成控制逻辑，其接线多而复杂、体积大、功耗大、故障率高，灵活性和扩展性很差。而PLC采用存储器逻辑，其控制逻辑以程序方式存储在内存中，灵活性和扩展性都很好。
（2）工作方式——继电器控制线路中各继电器同时都处于受控状态，属于并行工作方式。而PLC的控制逻辑中，各内部器件都处于周期性循环扫描过程中，各种逻辑、数值输出的结果都是按照在程序中的前后顺序计算得出的，所以属于串行工作方式。
（3）可靠性和可维护性——继电器控制逻辑使用了大量的机械触点，连线也多，可靠性和可维护性差。而PLC采用微电子技术，大量的开关动作由无触点的半导体电路来完成，PLC还配有自检和功能，可靠性和可维护性好。
