Distributed IO
Distributed IO is an application that can be used for data collection and various controls. With the characteristics of high reliability, favorable price, easy setup, convenient network cabling, etc., it is suitable for applications in scattered areas, which can save time and cost of system integration. In the past, control cables and PLC connections were used. Now the distributed I/O module is used, which can be connected to the PLC through a communication line, which greatly saves the wiring and the number of I/O points of the PLC itself.
Industry pain points
Low level of automation: For now, many chemical tank farms have a low level of automation and still rely on a large number of manual operations, resulting in low efficiency, high costs, and human error is difficult to avoid.
Old equipment: Some chemical tank farms have outdated equipment, backward technology, and lack of necessary maintenance and upgrades, resulting in low production efficiency, large safety hazards, and difficulty in meeting modern production needs.
Difficult safety management: chemical tank farms involve a large number of flammable, explosive and toxic substances, and there are many potential safety hazards.
High pressure on environmental protection: With increasingly stringent environmental regulations, chemical tank farms need to adopt more environmentally friendly materials and processes to control pollution emissions and reduce environmental impact.
Application examples
A large-scale chemical factory mainly produces and develops special chemicals based on long-chain fatty acids and their derivatives, and the products are mainly made of natural oils and fats. After the introduction of zero-point distributed IO, it participates in the automatic control of the centralized storage and recall of raw materials and finished chemical products. The plant has improved the level of automation, and at the same time, it has also improved the safety supervision system, which has achieved cost reduction and efficiency increase for the enterprise.
The original tank farm system uses Siemens 200smart as the master station, which has few IO points and a low degree of automation, which involves a lot of manpower control. This upgrade mainly upgrades the CPU, and uses zero-point distributed IO to centrally control the valves and motors of the entire tank farm, and monitor the temperature and liquid level of each tank in real time to ensure the safe storage of materials, as well as real-time deployment to improve the degree of automation.
