PLC is one of the three pillars of modern industry and is a highly reliable and widely used industrial control product. In medium and large modular PLC products, the CPU module (* processor) is the center of the PLC. Some major industrial production lines often require continuous operation can not stop, and no matter how high the reliability of the PLC can not guarantee zero failure, therefore, dual CPU redundancy control is an effective means to meet the requirements of continuous production and improve the availability of the system. The following takes the automatic control system of molten salt furnace as an example to describe the implementation method of double CPU redundancy control.

I. Overview of automatic system of molten salt furnace

The automatic control system of molten salt furnace is an important link in the dissolution production line of duralumin pipe, which controls the heating and circulation of molten salt, and uses the heat of molten salt to heat the aluminum ore pulp. The heating of aluminum ore pulp is very important, which affects the quality and output of the final product – alumina, so the temperature control and circulation control of molten salt are very important.

Due to the importance of molten salt furnace system in pipeline engineering, and considering that molten salt is an active chemical with different forms at different temperatures, solidification at low temperatures, unstable chemical reactions will occur at high temperatures, thereby corroding pipe walls and even exploding, safety, reliability, easy operation and automated management are the keys to system design. Therefore, consider using a set of double CPU redundant PLC, two sets of industrial computers, high-quality sensors, transmitters and actuators to control two 12 million calories of molten salt furnace, a salt pump, a group of salt valves, a molten salt tank and other related equipment, to achieve the automatic control of molten salt heating and circulation process, computer operation, monitoring and management.

The important components in the system, such as controller PLC, industrial computer (including display), communication network, power supply and key test points, all adopt redundant structure, and two sets of monitoring and operation management stations composed of two sets of industrial computer and large screen display run in parallel; Two redundant ControlNet high-speed communication networks transmit data simultaneously; Two sets of DC power supplies simultaneously supply power to the controller PLC, transmitter and switch input module, and the key test point sets two sensor test data at the same time.

The redundancy design doubles the reliability of the key components of the system and greatly improves the overall reliability of the system.
