具体成交价以合同协议为准（4）维修方便：这是因为：
①PLC工作可靠，出现故障的情况不多，这大大减轻了维修的工作量。这在讲述PLC的第三个特点时，还将进一步介绍。
②即使PLC出现故障，维修也很方便。这是因为PLC都设有很多故障提示信

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
集成电路是采用半导体制作工艺，在一块较小的单晶硅片上制作上许多晶体管及电阻器、电容器等元器件，并按照多层布线或遂道布线的方法将元器件组合成完整的电子电路。它在电路中用字母"IC"(也有用文字符号"N"等)表示。
技术，采用严格的生产工艺制造，内部电路采取了*的抗干扰技术，具有很高的可靠性。使用PLC构成控制系统，和同等规模的继电接触器
接触器是一种应用广泛的开关电器。接触器主要用于频繁接通或分断交、直流主电路和大容量的控制电路，可远距离操作，配合继电器可以实现定时操作，联锁控制及各种定量控制和失压及欠压保护，广泛应用于自动控制电路，其主要控制对象是电动机，也可用于控制其它电力负载，如电热器、照明、电焊机、电容器组等。 [全文]
系统相比，电气接线及开关接点已减少到数百甚至数千分之一，故障也就大大降低。此外，PLC带有硬件故障自我检测功能，出现故障时可及时发出警报信息。在应用软件中，应用者还可以编入外围器件的故障自诊断程序，使系统中除PLC以外的电路及设备也获得故障自诊断保护。这样，整个系统的可靠性*。
