vrf Direct IO Input Variables??

Question asked by Dr_joel Employee on Dec 16, 2002
Hello Justin,
     The first two examples won't work, Kathy and Doug have sent examples.  The third choice you gave -should- have worked.  I often use that method to test out a direct IO.  Two thoughts on why it might not work:

Some instruments like to see a terminating semicolen as int ":sour:volt 2;"
Others don't like the EOL.

Other than that, maybe the command is not correct.  As I said above, I would have thought the last choice should work.

Subject: [vrf] Direct IO Input Variables??



Using direct IO, looking to set a power supply based on user input/variable.
Tried using an input pin on the direct IO as a variable but have not been
able to get it to work.  Here are a few of the things I have tried (X is the
input pin on the Direct IO):

     WRITE TEXT ":sour:volt X" EOL          X = 2  (X is int32)
     WRITE TEXT ":sour:volt X" EOL          X = 2  (X istext)
     WRITE TEXT X EOL               X = ":sour:volt 2"  (X is
text)

Tired other combinations - not luck.
Any idea's??

Thanks
Justin
