How to choose DCS and PLC?
How to choose between PLC and DCS depends on the specific project and plant type. Because of different applications, the requirements of the control system are also different.
In addition to some basic criteria, we must also consider the installation, scalability, maintenance and other factors. Sometimes, one choice is very suitable for a factory, and in another case it may not be. Therefore, the more factors considered in the selection of control system, the more conducive to the realization of short-term and long-term goals.
At present, although PLC system may be the most cost-effective for small equipment, DCS system provides more economical scalability and is more likely to obtain higher initial return on investment.
PLC is suitable for discrete production, generally composed of separate production devices, mainly used to complete the assembly of components, such as labeling, filling or grinding. DCS is suitable for process manufacturing. Automated systems are often used to produce by recipe rather than by piece in a continuous and batch manner. Large scale continuous processing equipment, such as refineries and chemical plants, all use DCS system. Mixed application usually uses PLC and DCS at the same time.
