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。   Telemecanique XBT-F034310, , XBTF034310, Fast ShippTelemecanique XBT-F024310, , XBTF024310, Fast ShippSiemens 6AV3627-1JK00-0AX0 OP27, , 6AV36271JK000A...Siemens 6ES5 945-7UA21, , 6ES59457UA21, Fast ShippiMitsubishi A3UCPU, , A3UCPU, Fast ShippingTelemecanique XBT-F023310, , XBTF023310, Fast ShippTelemecanique XBT-F034510, , XBTF034510, Fast ShippBeijer E900VT, , E900VT, Fast ShippingSiemens 6SC6130-0FE00, , 6SC61300FE00, Fast ShippingSiemens 6ES7 621-1AD01-0AE3, , 6ES76211AD010AE3, FasBeijer Cimrex 91D, , CIMREX91D, Fast ShippingSiemens 6FM1723-3BA00, , 6FM17233BA00, Fast ShippinBeijer E900T, , E900TBeijer, Fast ShippingSiemens 6ES5 308-3UC21, , 6ES53083UC21, Fast ShippinSiemens 6ES7 623-1AE00-0AE3, , 6ES76231AE000AE3, FaSiemens 6ES7 623-1AE01-0AE3, , 6ES76231AE010AE3, FaBeijer Cimrex 90, , CIMREX90, Fast ShippingKollmorgen AKI-CDF-MOD-10T-000, , AKICDFMOD10T000, FBeijer E1100, , E1100Beijer, Fast ShippingSiemens 6AV7671-2AA00-0AA0, , 6AV76712AA000AA0, FastSiemens 6ES5 955-3NC41, , 6ES59553NC41, Fast ShippiSiemens 6ES5 241-3CA11, , 6ES52413CA11, Fast ShippiSiemens 6ES5 242-1AA41, , 6ES52421AA41, Fast ShippinSiemens 6ES5 526-3LA11, , 6ES55263LA11, Fast ShippinSiemens 6ES5 955-3LC14, , 6ES59553LC14, Fast ShippinSiemens 6ES5 955-3LC42, , 6ES59553LC42, Fast ShippiSiemens 6ES5 955-3NF11, , 6ES59553NF11, Fast ShippiSiemens 6ES7 315-2AF83-0AB0, , 6ES73152AF830AB0, FasMitsubishi A3ECPU-R21, , A3ECPUR21, Fast Shipping
