PSR-SPP-24UC/ESA4/2X1/1X2为了让大家更好的理解，我们举个简单的例子。比如说现在有一台空调，它是通过PLC控制的。这台PLC的程序是外界温度低于20摄氏度时空调制冷关闭，超过20摄氏度时打开。既然涉及温度了，肯定PLC需要采集温度信号，一般都是b接口连接一个温度传感器什么的。随着外界温度的不断上升，从5度10度一直提升到20摄氏度，相应的信号传达到PLC里，根据程序发出打开空调的指令，指令通过OUTput接口到底空调开个那里，这个开关应该是个模拟量开关，会持续的打开。当空调不断制冷，室内气温逐步下降，气温降到20摄氏度以下后，PLC根据新的采集到的信息，发出关闭空调的指令，空调关闭，气温再次逐步上升，由此循环往复，从而实现空调的智能化降温。
不管是哪种型号的PLC，它们都会集成通讯模块进行IO扩展或者是与上位机连接，从而实现更多的操作。老式的PLC一般只有以太网接口以及串口接口，CAN接口的很少，想要扩展需要花费大笔银子，尤其是西门子这样的国外厂家，做好挨宰的准备就对了。而广成科技开发自带CAN总线的PLC，完美满足您的需要，如果想要的话，欢迎加微信183-0981-5706进行咨询。
