Thanks for your reply Keith,
These informations will help me for this application. I am writing the program and it will be possible to test it this week I hope.
In fact we used the V130 for a analogic duplicator for the 2 The analogics outputs.
We read the 2 Ana Inputs and them send the value to the 2 Outputs for 2 machines that used it.
And this use, as analogic signal duplicator, is cheaper than other way.
