FP-AO-210 cycling

[Mr. Bill]

Hello,

I am trying to get the FP-AO-210 module to cycle an output channel.  I am using Labview version 7.1.  Is it possible to cycle the channel every 30 seconds?  I have tried to find a way to do this but I am just learning how to program with Labview. 

I am also having a problem with the inputs from a potentiometer.  I can not get the FP-AI-110 module to see the input. 

As any you could provide would be greatly appreciated.

Thank you in advance for your help.

Bill

Hi Mr. Bill,

From what I understand, you're trying to output a periodic signal from a channel on the FP-AO-210 module.  What you can do is time a loop such that you output at a certain rate to the channel.  You output whatever you want.  You could set up an array, and when you output everything in the array, you could start over at the beginning again.  In this manner, you would be outputting a periodic signal.  This is just one idea.  The size of the array would depend on how often you updated the signal output.

As far as seeing your potentiometer, your FP-AI-110 will never be able to see it since your module is expecting a voltage signal.  Your potentiometer is a resistor.  If you connect the potentiometer to a voltage source and read the swiper of the potentiometer, then you can detect the voltage difference dependent on what position the potentiometer is in.
