The main functions of 3008 include executing control logic, data processing and communication, online diagnosis and fault detection, etc. It can receive signals from sensors and other input devices, calculate and judge based on preset control logic, and then send control instructions to the executing mechanism to achieve precise control of industrial processes. At the same time, it can also process a large amount of data and support multiple communication protocols to ensure accurate transmission and real-time performance of data.

The main processor of 3008 can transmit data to communication modules through the communication bus, supporting up to 118 I/O modules (analog and digital) and optional communication modules. These communication modules can be connected to various devices and systems, including Modbus master and slave stations, Foxboro and Honeywell distributed control systems (DCS), etc.

In addition, 3008 also utilizes programming software based on the WINDOWS system to develop and debug control programs, further improving its programming and configuration flexibility.

Each I/O module of 3008 is equipped with intelligent functions to reduce the workload of the main processor. The input module filters and repairs the input, and diagnoses hardware faults on the module; The output module provides information for the voting of the output data, checks the effectiveness of the output status through the feedback loop voltage at the output end, and can diagnose problems with the on-site circuit.

The application field of 3008 is very extensive. In the field of industrial automation, it can be used to monitor and control various parameters in the production process, such as temperature, pressure, flow rate, etc. In the field of process control, such as chemical, petroleum, natural gas and other industries, it can monitor and collect data related to production processes to ensure process stability and safety.
