摘要
本文系统以AB SLC500系列PLC为基本控制部件,实现了生产过程中温度、压力、和电流等600多个点的信号采集,同时对输出负载(电磁阀、泵站)进行远程控制,从而达到参数调节的目的。上位机以InTouch为操作平台,通过工业以太网与现场控制器进行通信,使系统的通用性和稳定性大大提高,同时实现了数据的采集显示、超限报警、报表查询和打印输出等功能。
In this paper,the basic control component of system employed AB SLC500 series PLC,the system was successful in acquisition of more than 600 signals,such as temperature,pressure,and current,etc.Signals output impact remote control on the valve and pump station in the purpose of regulating parameters.The system used the software InTouch to make the PC monitor configuration interface,acquisition nodes communicated with the host computer through the industrial Ethernet which is to make the system＇s versatility and stability is greatly increased.Meanwhile the system achieved those functions such as the collection and display of data acquisition,realtime alarming, printout,etc.
