3HAC020988-008 Distributed control system

The 3HAC020988-008 is ABB’s high-performance, modular distributed control system (DCS) for a wide range of industrial automation applications.
It has the following basic functions:
Control logic execution: This component is a key part for executing control logic, monitoring and controlling industrial processes according to predefined procedures or algorithms.
Data processing: It is responsible for receiving analog and digital signals from field devices (such as sensors, actuators, etc.), processing these signals, and sending the processed data to other system components or host computers for display and analysis.
Communication function: It has the ability to communicate with other system components, devices or host computers, and realizes the exchange and sharing of data through standard communication protocols (such as Modbus, Profibus, Ethernet, etc.).
Fault diagnosis and alarm: The component has fault diagnosis and alarm functions, which can detect abnormal situations in the system and generate corresponding alarm information for operators or maintenance personnel to deal with in time.
System Configuration and Diagnostics: It also supports system configuration and diagnostics, allowing users to configure, debug, and diagnose the system through specific software tools.
