[Marcusius]

Hello.

During communication with my serial device I sometimes get the error code –1073807232 which is VI_ERROR_WINDOW_MAPPED.
I have no idea how to eliminate it.
Anybody of you?

Please help.

PS: I am using LabView 7.0.

Can you post your code or a screen shot of your block diagram?

Hello Marcusius

I suspect that this error comes due to not opening or closing the VISA Session with [VISA open] and [VISA close].

For further Investigation i can only assent to muks and ask you to post a screenshot of your blockdiagram.

R u ensuring you are closing the sessions properly?
