Many auxiliary chemical facilities in large chemical bases are far away from the operating room, some as far as several kilometers or tens of kilometers, but considering the need for centralized monitoring and control, another set of facilities will be built dcs the system cost is too high，Remote I/O it has its unique advantages and can communicate with DCS, saving a lot of costs. Generally, DCS and PLC cannot achieve centralized control over long distances, so remote I/O is the development trend for remote control. At the same time, in highly automated and intelligent industrial environments, industrial buses play a crucial role as the nerve center connecting various devices, sensors, and actuators. The IO (Input/Output) module, as a key component of industrial bus systems, not only realizes data acquisition and transmission, but also promotes seamless collaboration between devices, greatly improving the efficiency and flexibility of industrial production. Beijing Mingda Intelligent Control Technology Co., Ltd. has developed and produced remote IO modules based on this actual production situation, which have played a huge advantage in the application of petrochemical industry production. With independent key technologies, they are both innovative and practical.     

The Mingda Intelligent Control MR30 Remote I/O Series adopts a lightweight and compact module design in the application of cabinets and equipment, and reduces the use of power supply modules to save cabinet space to the greatest extent. During system or equipment maintenance, the MR30 series distributed IO modules can be freely hot swappable to replace I/O modules without changing the wiring, plug and play, greatly improving system utilization and saving valuable time. With its medium redundancy technology, the system operation process is further optimized, greatly reducing or even eliminating the impact of single module failures on data monitoring and acquisition in petrochemical production processes, achieving uninterrupted production and more convenient operation and maintenance.

Application Cases

We have installed the MR30 distributed remote IO system developed and produced by Beijing Mingda Intelligent Control Technology Company at the petrochemical production and transportation site control station. The main task is to collect various signals such as temperature inside the storage tank, temperature at the outlet of the loading platform pipeline, combustible gas alarm, grounding alarm, flow meter, liquid level meter, etc., and monitor and manage various process equipment and intelligent instruments on site. At the same time, it communicates directly with the monitoring station through Modbus TCP protocol to remotely monitor the working status of the instruments inside the tank. When the instruments fail, the system will automatically alarm, display the oil delivery process and the status of related equipment (analog information such as liquid level, temperature, flow rate, etc.) in real time, upload them to the control center, and accept instructions and data from the control center to complete functions such as printing alarm information and reports. Ensure the system operates safely, reliably, smoothly, efficiently, and economically. Mingda Intelligent Control MR30 remote I/O, through the LED on its device and the status displayed on each module, can easily see the clear layout of the system's operating status and make quick and timely diagnosis.
