EMERSON Emerson VE4022 controller, Ltd. is engaged in technology development, consultation, transfer, and sales of electrical equipment, automation equipment, electronic products, communication products, and electromechanical products in the fields of intelligent technology, information technology, and automation technology. Industrial automation products: PLC, DCS, sensors, frequency converters, encoders, relays, servo drives, soft starters, touch screens. The brands involved in the product include: Continental, Schneider, Siemens, ABB, SICK, P+F, E+H, FANUC, GE, Eaton Electric, CT, EMERSON. The Emerson VE4022 controller control station uses PLX system to complete thermal control and process parameter detection of the heating furnace. The processor 1757pl52a of this system is a Rockwell specific processor with 8mRAM. The high-speed motherboard is integrated with the network, and the I/O modules can be plugged in and out with power, and can be arranged arbitrarily. In this system, the control station is equipped with one main frame and two expansion frames, completing the 6-stage temperature control of the entire heating furnace, more than 60 points of analog quantity detection, and more than 20 switch quantity inputs and outputs.

The system template adopts the following: 4 756 of 6ci/a modules, 9 1756ib16d/a modules, 2 1756ow16i modules, 4 1756if6i/a modules, 5 1756ir6i/a modules, and 4 1756it6i/a modules. In order to improve the reliability of this system, all AI, DI, and DO have been isolated from the site, and the AI template also uses a dual isolation template with isolation between channels. Program according to the determined control rules and choose to use according to the working conditions of the heating furnace. The field signal sampling, gas flow fuzzy control loop, air flow fuzzy control loop, and temperature fuzzy control loop are programmed into subprograms, modularized, and called in the main program to facilitate debugging and control function configuration. This network belongs to a passive high-performance multi bus with a transmission speed of 5m. The data transmission adopts a deterministic transmission method, greatly reducing the amount of data transmission. The on-site instrument control valve adopts a high-temperature resistant control valve, the actuator adopts a pneumatic actuator, and the pressure and differential pressure transmitters use Fisher 3051 transmitters.
