摘要
越来越多的自动化设备自身配置有串行通信接口(如自动化仪表、变频器、伺服驱动器等),在工业控制现场与可编程逻辑控制(PLC)之间需要进行大量的数据传输,包括现场数据采集、设备的远程控制等。本文以欧姆龙中型CJ2系列PLC协议宏功能为例,比较以往串行通信功能,在可靠性、程序繁琐程度、调试方便性等几方面的优越性。
More and more automation equipment configures serial communication interface, ( Automation, Instrumentation, Frequency, converter, Servo drive ). Between the industrial control field and the programmable logic control ( PLC ) it needs a large number of data transmission, Field data acquisition, remote control equipment. This paper takes the OMRON CJ2series PLC protocol macro function as an example, Compares to previous serial communication function to get the advantages in reliability, cumbersome procedures, debugging convenience and other aspects of.
