在60年代，汽车生产流水线的自动控制系统基本上都是由继电器控制装置构成的。当时汽车的每一次改型都直接导致继电器控制装置的重新设计和安装。随着生产的发展，汽车型号更新的周期愈来愈短，这样，继电器控制装置就需要经常地重新设计和安装，十分费时，费工，费料，甚至阻碍了更新周期的缩短。为了改变这一现状，美国通用汽车公司在1969年公开招标，要求用新的控制装置取代继电器控制装置，并提出了十项招标指标，即：
(1）编程方便，现场可修改程序；
(2）维修方便，采用模块化结构；
(3）可靠性高于继电器控制装置；
(4）体积小于继电器控制装置；
(5）数据可直接送入管理计算机；
(6）成本可与继电器控制装置竞争；
(7）输入可以是交流115V；
(8）输出为交流115V，2A以上，能直接驱动电磁阀，接触器等；
(9）在扩展时，原系统只要很小变更；
(10）用户程序存储器容量至少能扩展到4K。
