The main functions of PLC in the electric order picker stacker:
①Switch logic control: Use PLC to replace the traditional relay contactor of electric order picker for logic control.
② Timing/counting control: It is realized by the timing/counting instruction of PLC.
③Step control: realized by step command.
④Data processing: The electric order picker reclaimer is controlled by PLC, which can carry out data transmission, comparison, shift, numerical conversion, arithmetic operation and logic operation.
⑤Process control: It can realize automatic adjustment of non-electrical parameters such as temperature, pressure, speed and flow of electric forklift equipment.
⑥ Motion control: single-axis or multi-axis control through high-speed counting module and position control module.
⑦ Communication network: Through the networking between PLCs and the connection with the computer, the remote control or intelligent control of the electric order picker is realized.
⑧Monitoring: It can monitor the operation of each part of the system, and can modify the control program and set value online.
⑨ Digital and analog conversion: A/D and D/A conversion can be performed to apply to analog control.
(2) Main features:
①High reliability and strong anti-interference ability.
②Complete functions, simple programming, flexible combination and convenient expansion.
③Small size, light weight and low power consumption.
