DCS安全性：为保证DCS控制的设备的安全可靠，DCS采用了双冗余的控制单元，当重要控制单元出现故障时，都会有相关的冗余单元实时无扰的切换为工作单元，保证整个系统的安全可靠。PLC所搭接的系统基本没有冗余的概念，就更谈不上冗余控制策略。特别是当其某个PLC单元发生故障时，不得不将整个系统停下来，才能进行更换维护并需重新编程。所以DCS系统要比其安全可靠性上高一个等级。Siemens 6ES7 321-1BL00-0AA0, 6ES73211BL000AA0, FaSiemens 6ES7 421-1BL00-0AA0, 6ES74211BL000AA0, FaSiemens 6GK1500-0AB0, New, 6GK15000AB0Mitsubishi A1S-58B-S1, A1S58BS1Mitsubishi A1S-61PEU, A1S61PEUMitsubishi A1S-62PN, A1S62PNMitsubishi A1S-63P, A1S63PMitsubishi A1S-65B-S1, A1S65BS1Mitsubishi A1S-D61, A1SD61Mitsubishi A1S-NMCA-8KE, A1SNMCA8KEippinMitsubishi A1S-X20, New, A1SX20Mitsubishi A1S-Y50, New, A1SY50Mitsubishi A35B, A35BMitsubishiMitsubishi A38B, A38BMitsubishiMitsubishi A55B, A55BMitsubishiMitsubishi A58B, A58BMitsubishiMitsubishi A62P, A62PMitsubishiMitsubishi A68B, A68BMitsubishiTelemecanique ABE-6SD2520, ABE6SD2520ippMitsubishi AC12B, AC12BMitsubishiMitsubishi AL6-MR-A Complete, New, AL6MRAPAKETMitsubishi AX42, AX42MitsubishiMitsubishi AY41-UL, AY41ULYaskawa Beijer ST1, New, BEIJERST1Omron C200H-IA122, C200HIA122Omron C200H-IA222, C200HIA222Omron C200H-ID212, New, C200HID212Omron C200H-ME831, C200HME831
