Why calling initDIO after every read or write

[Schicki]

I wish to know why my LW-CVI program with NI-DAQ works perfectly using
the Dig_Block_In function on an DIO-32HS only once. I mean, if the program
restarts, I read perfectly data from the peripheral device connected to the
board, but if I push again my "acquire" button, which indeed starts DIg_block_in,
the program does not acquire anymore. I do not want to use Init_DA_Brds every
time I wish to perform a Dig_Block_In ...
Thanks !

Hi,

Normally you do not need to initialize with Init_DA_Brds for each Dig_Blick_In.

I think there is anything else wrong.

If you get an error message, you should follow its way.

Maybe you compare your program with one of our examples.
