DCS is a system including the upper software, network and controller, while PLC is only a controller. To form the system, the upper SCADA system and the network connected with it are also required.

For PID loop control, Mitsubishi process controller can also realize FBD programming like SAMA configuration; The DCS system is larger, the number of control loops is more, and there are more controls and algorithms, which can complete the control between more complex loops. Hardware reliability is similar. DCS can achieve I/O redundancy, but PLC cannot. Relatively speaking, the system composed of PLC has lower cost.

——Manager of Mitsubishi Electric Automation Precision Control Department

DCS is a kind of "distributed control system". The hardware includes field controller, operator station computer, engineer station computer, and network system to contact them; DCS software is an overall scheme, which solves all technical problems of a system, and all parts of the system are closely combined.

PLC is a device, and its hardware is equivalent to the field controller in DCS; The software is a local scheme, and the organization between stations is loose.

——Technical Manager in charge of APROL product application development in Baikale

To analyze the difference between DCS and PLC, two key points are: first, DCS is a distributed control system with a global database; Second, PLC is a sequential scanning mechanism, and DCS is a time based control. Our system conforms to the first point. For example, the modification of an I/O tag can also be synchronously reflected in the HMI.
