Needed code for temperature controll

Recommended Posts

Dear colleagues,

I have a trouble with programming JAZZ JZ20-UA24, due to lack of knowledge.

Does anybody have ladder code for simple temeprature operation with thermocouple.

Variables> Set Temperature, Hysteresis, and it should work when actual temo is less then set, to make outup ON, and if not, to OFF.

Next on is when temperature drops below Set-Hys.

I know it is simple, but not for me.

Please find in Unitronics U90 ladder Help sample project:

C:\Program Files\Unitronics\Unitronics U90 Ladder\Examples\PID\On off with hysteresis.U90 and open it.

Please "Save as" this project with New name. In HW Configuration section of project change controller type to JZ20-UA24. Open this controller configuration.

Please configure analog input Type (proper termocoupler type must be used) and select MI0 - destination for Analog input.

Download project to PLC and use O0 to control the heater (you must use properly connected  SSR or contactor for power control).

Read JAZZ JZ20-UA24 hardware configuration manual for connect TC on p.5
