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.
■ process scale:
Small system (<300 i / o points) may have less budget, so plc is more suitable. dcs has a global database, which is easier to manage and upgrade, and can play a more important role in large factory applications.
■ upgrade plan:
PLC system can be selected for small-scale industrial process, but if the process needs to be expanded or upgraded, more PLC hardware and database need to be added, and independent maintenance is needed. This process is time-consuming and laborious, and prone to errors. At this time, DCS is more suitable. As DCS is easier to upgrade, it can also manage users&＃39; trust from the central hub, so it is easier for later maintenance.
Integration requirements:
For stand-alone device, PLC is the ideal choice. When the factory configures multiple PLCs, it will produce the requirement of interconnection. This is generally difficult to implement because it is usually necessary to map data using communication protocols. Especially when the user needs to change, once a PLC system is changed, the two PLCs may not communicate normally. DCS does not need mapping, configuration change is just a simple process, the controller is the system&＃39;s own.
