摘要
在工业控制中,可编程控制器PLC得到了广泛的应用。目前PLC与仪表的通信方式有很多种,如RS232通信、RS422/485通信、Profibus通信等。详细介绍了三菱Q系列PLC与固伟GPI-735A安规测试仪通过RS232协议通讯的方法。
Programmable logic controller （PLC） has been widely used in industrial control. At present, a PLC can communicate with an instruments in many ways, such as RS232 communication, RS422/485 communication, Profibus communication. This paper introduces the communication of an Mitsubishi Q series PLC and a Gowel GP1-735 which is a safety tester through RS232 protocol.
