Hello
This is the first time i am even doing PLC programming.
I am basically trying to ocntrol a proportional valve whihc takes in a continuous input of 4-20 mAmp. Thus at 4 mAmp it is completely closed and at 20mAmp it is fully open.
For the input i have a temperature sensor, downstream of the valve where the stream is mixing with a hot water stream. now i need the valve to close or open to change th emixing temperature according to a curve i have.
Well i just need to know how to begin. i have an idea however i do not know how to get the results in a aprticular amount of time since the curve is strictly time dependant.
Any help would be highly appreciated.
Thank you
