【英文介绍】

EMERSON Emerson VE4022 Controller, automation technology in the field of technology development, technical consulting, technology transfer, electrical equipment, automation equipment, electronic products, communications products, electromechanical products sales. Industrial automation products: PLC,DCS, sensor, inverter, encoder, relay, servo drive, soft starter, touch screen. Products involved in the brands are: Continental, Schneider, Siemens,ABB,SICK,P+F,E+H,FANUC,GE, Eaton Electric,CT,EMERSON Emerson VE4022 controller control station uses plx system for the thermal control of the heating furnace and process parameter detection. The system's processor, the 1757pl52a, is a Rockwell-specific processor with 8mram, a high-speed backboard integrated into the network, and i/o modules can be plugged in and out of the box. In this system, the control station is equipped with one main frame and two extension frames, which can control the temperature of the whole heating furnace in 6 stages, detect the analog quantity of more than 60 points and input and output of more than 20 switching quantities.

The system template consists of four 756 of6ci/a modules, nine 1756ib16d/a modules, two 1756ow16i modules, four 1756if6i/a modules, five 1756ir6i/a modules, and four 1756it6i/a modules. In order to improve the reliability of the system, all ai, di and do are isolated from the field, and the ai template also uses a dual isolation template with isolation between channels and channels. According to the established control rules of programming, according to the condition of the heating furnace to choose the use. The sampling of field signal, fuzzy control loop of gas flow, fuzzy control loop of air flow and fuzzy control loop of temperature are modularized and called in the main program to facilitate debugging and control function configuration. The network is a passive high performance multi-component bus with a transmission speed of 5m. Data transmission adopts deterministic transmission mode, which greatly reduces the amount of data transmission. The field instrument control valve adopts high-temperature control valve, the actuator adopts pneumatic actuator, and the pressure and differential pressure transmitter adopts fisher 3051 transmitter.
