HI i would also like to use labview to control a solenoid valve using a HP data acquistion system (HP 34970A)+ multifunctional module.
Is it possible to do temperature measurement also using multifunctional module?
Are the drivers common for all modules?
Is it possible to read data from one module and set the output of a multifunctional module accordingly?

Hi
I am trying to write a simple code on Having a Loop control on a flowmeter. I wrote 2 codes one involving a P control and one Involving a Differnce in the set Point to the Actual output.
The idea is to control a flowmeter based on the pressure of flow . The Pressure measurement gives a Voltage output and the valve need a Current input so i need to control flow using desired Voltage output. But my code with the P control doesn not function as desired. ANd the code which uses just a differnce in a loop seems to work fine but for the fact that it never touches the desired value . it keeps oscilatting around the desired set point.
Could anyone help me set right the P Control ?

Hi shanky1023 ,
Do you have the PID toolkit? It might make it easier for you to write the code. I don't have your subvi's or DAQmx vi's but the PID toolkit has all the PID subvi's to control a flowmeter. I would look into that. Let me know if you have any questions.
