Hello all,
I am very new to LabVIEW programming.I've an application where it's required to acquire temprature data at a perticular duration from a heater.Depending upon the differance between current temp (process varible)and set temprature,heater has to make ON and OFF in a controlled way to reach the set value.
I have made a loop where i am acquireing temp data at every 30 sec interval and depending upon temprature diff between set value and present value ,am genarting a pulse (for eg. 22 sec on period and 8 sec off period).Inside that loop I am driving the "True" value to DIO of CompactRIO for ON period to make the heater ON .Problem what I am facing is the heater is not gaetting ON at Exact 0 to 22 sec and not OFF from 22 sec to 30 sec.
i have tried to use separate loop for acustion ,analysis and control but not able to synchonise all.Heater is getting ON and OFF randomly.Please help.
thanks
