费大量时间及人力和物力去改制、安装和调试。 这种电路接线多,只适用于小型的控制电路。 采用 PLC 控制比继电器控制好的多,我们采用 PLC 来控制。 ( 1) 可靠性高,抗干扰能力强 , 高可靠性是电气控制设备的关键性能。 PLC 由于采用现代大规模集成电路技术,采用严格的生产工艺制造,内部电路采取了先进的抗干扰技术,具有 很高的可靠性。 ( 2) 配套齐全,功能完善,适用性强 PLC
的为简易编程器,多只接受助记将编程,个别的也可用图形编程(如日本东芝公司的 EX 型可编程控制器)。 复杂一点的有图形编程器,可用梯形图语编程。 有的还有专用的计算机,可用其它高级语编程。 编程器除了用于编程,还可对系统作一些设定,以确定 PLC 控制 第 13 页共 83 页 方式,或工作方式。 编程器还可监控 PLC 及 PLC 所控制的系统的工作状况,以进行 PLC 用户程序的调试。
