[lovexf]

Hi，friends

    Now I have a problem about cFP-PWM-520, I'd like to change the period of the pluse in labview program ,not in the channel configuration dialog box, is that possible? I have a step motor, it controled by the numbers of the pulse,so in my project, I need to change the speed of the motor by change the period of the pluse, if that possible, how can I do? or what instrument should I need to buy?or something else?

   thank you

Bluse,

You should be able to change this from your program using the Fieldpoint>Advanced>Ethernet Advanced>configure atttribute.vi.

Try using the search feature on the functions pallette.

    I need your help again,now I am trying with that vi you mentioned last time,but when I run this VI,error comes,and I don't know what's wrong with it,here are VI and picture~~the duty can run with no problem，but。。。

I don't have one of these modules here to test.  Suggest that you contact NI directly to verify proper use of this vi for this particular module and attribute.

Double check your Fieldpoint path in the purple constant.  In the background of your screenshot, you have a weird W character with a horizontal strikethrough rather than a normal backslash.

no，it‘s OK，you didn't see the program clearly,now I make a new one ,I don't know how to use that Configure Attribute.VI,there is no example about that part,so could you like to find a example for me or help me to solve this problem? It troubles me so much~~
