While industrial controllers and central controllers are very similar, there are some differences:
Different uses: industrial controllers are usually used for automation control and data acquisition and processing of industrial control systems; central controllers are usually used for central control systems in large buildings or smart homes, and are responsible for controlling the operation of the entire device or system.
Differences in processing power: Since industrial controllers have to handle real-time data, they require higher processing power and faster response speed; while central controllers usually do not need to handle large amounts of data and real-time control, and have relatively low processing power.
Differences in expandability: Industrial controllers are usually more expandable, and more slots, interfaces, and modules can be added as needed; while central controllers are usually more fixed, less expandable, and rarely have the opportunity to be upgraded.
Different working environments: Industrial controllers are usually used in harsh industrial environments and need to have higher durability and reliability, while central controllers are more often used in stable environments such as homes or offices.
Different hardware configurations: Industrial controllers usually have more stringent hardware configuration requirements, and need to have features such as anti-electromagnetic interference, dustproof, waterproof, and shockproof; while central controllers usually do not need these features.
