在全世界上百个PLC制造厂中，有几家举足轻重的公司。它们是美国Rockwell自动化公司所属的A．B(AllenBradly)公司、GE-Fanuc公司，德国的西门子(Siemens)公司和法国的施耐德(Schneider)自动化公司，日本的三菱公司和欧姆龙(OMRON)公司。这几家公司控制着全世界80%以上的PLC市场，它们的系列产品有其技术广度和深度，从微型PLC到有上万个I／O(输入，输出)点的大型PLC应有尽有。
系统管理程序主要控制PLC的运行，使PLC按正确的次序工作；用户指令解释程序将PLC的用户指令转换为机器语言指令，传输到CPU内执行；功能程序与系统程序调用则负责调用不同的功能子程序及其管理程序。
１、顺序控制
系统中采用ifix软件作为上位机的监控软件。Ifix作为一种多方面的监控软件，提供了与多种PLC通讯的I/O驱动程序，可方便的与PLC连接，在工业控制领域有着广泛的应用。监控系统包括SCADA系统和HMI图形系统。SCADA系统通过与PLC建立通讯关系通过软件接口I/O驱动程序与PLC直接建立通讯来读取数据，并形成实时数据库。HMI图形系统显示实时数据和报警信息，记录历史数据，打印报表，修改设定参数以及实现软手动控制等。
利用该软件的变量存档编辑器和水晶报表设计器，可以很方便地为运行用户过程数据生成用户档案并生成报表。利用ODBC功能，把所有设备的报警和人员的操作都记录下来，通过声音通知操作人员，以便使操作人员能够立即进行处理，并给日后事故原因的分析创造有利条件。
②由程序控制，工作可靠……PLC平均无故障工作时间长，长达3万小时以上
