In the earliest days, automatic control could only achieve simple on/off functions, such as DI and DO—essentially mechanical start/stop operations. Later, these controlled elements were centralized in control rooms, enabling batch control operations. However, centralized control systems were vulnerable to single points of failure; a critical path error could paralyze the entire controlled area. This led to the gradual adoption of Distributed Control Systems (DCS).

A DCS is a distributed control system commonly used in industrial settings. It incorporates multiple operator stations to enhance system redundancy, allowing personnel to view configuration monitoring and perform operations on various equipment from the central control room. For example, in industrial boiler production, the water level in a tank must be maintained within a certain range. Operators can either manually adjust the water level control valve on-site or issue commands through the DCS to make adjustments.

The DCS acts as the "brain"—it responds to what the "eyes" see (i.e., signals transmitted from field instruments, such as a drop in water level) by issuing commands (e.g., increasing the opening of the inlet valve). The field actuators then receive and execute these commands (e.g., opening the inlet valve wider to keep the water level within range).

The DCS data acquisition gateway launched by WideIOT enables data collection from the DCS and converts it into standard formats for upload to monitoring platforms. It supports various communication methods, including 5G, 4G, Wi-Fi, and Ethernet. Through mobile terminals such as smartphones and computers, users can monitor data such as temperature, pressure, liquid level, and flow, as well as perform configuration monitoring and control of equipment like motors and pumps—delivering efficient and convenient workflows and user experiences for enterprises.
