    Hi,
    I need a help, 
    I made PID temperature regulator in GX Works3 FBD/LD program.
    I don't know  how to write my paramerers. Amount of  Proportional gain and Integral time are  P= 0.072 and  Ti=144.82s, dont use KD. ) In manual for Kp writes setting range is 1 to 32767 (%) and I dont' know how ti write my value. What meant this precentage. For Ti Setting range is 0 to 32767 (x100 ms), here I need writes my time in ms?

    please help !!!

    Hi,
    I realy need a help, I am stuck.
    I need  to make PID temperature regulation for Mitsubishi plc fx5u in GX Works3 FBD/LD program. I don't have any modul fo temperature sensor. I use NTC resistor connected to AD. I use PID function block. I made almost all program but I don't understand two things:
    1. How to input my paramerers ( Before I made matlab simulatiom of proces and I got the paramerers, Proportional gain and Integral time. problem is my P= 0.072 and ma Ti=144.82s, dont use KD. ) In manual writes;s etting range is 1 to 32767 (%) and I dont now how ti writ my value. What meant this precentage. For Ti Setting range is 0 to 32767 (x100 ms), here I need writes my time in ms?
    2. I don't now how to connected my output of PID (MV) to turn on and off heater. Can I use PWM function? Or i need to use high speed timer? 

    Can it make like I started or need to change all conncept?

    please help me!!!!

    Hi,
    I'm new here realy need a help, I am stuck.
    I need  to make PID temperature regulation of heat chamber ( for my school work), using Mitsubishi plc fx5u in GX Works3 FBD/LD program. I don't have any modul of temperature sensor.
