This paper mainly introduces the experimental furnace of PLC control design, asked to complete test furnace PLC control system design, software design, ladder diagram design, electrical diagram design and commissioning. This design mainly PLC programmable controller for the core, with the programming sensor detection technique, A/D and D/A conversion technologies, PID regulation technology, configuration software monitoring technology, make electric furnace temperature can set temperature curve changes in accordance with.
The focal point of design for the formation of PLC temperature curve 4DA FX2N - FX2N - 4AD module and the application of application, PID adjustment, MCGS software to monitor realization. One of the whole system of PLC control FX2N motion process, 4DA, FX2N - - to collect 4AD will temperature of the A/D and D/A transformation, PLC will be collected to temperature and internal set good temperature compare, MCGS software will real-time temperature curve shown to users, increase
