VISA Enable Event : Error -1073807339

[sumit04]

Hi,

Whenever device driver tries to execute "VISA Enable Event" function with event type "Service Request" It gives an error "Error -1073807339 occurred at VISA Enable Event in Agilent 3352X Series.lvlib"

I am successfully executing *IDN?\n command and reset command using VISA.

HI,

I didn't get any solution for the same problem, but I have a work-around to avoid that problem.

The Reset.vi causing an issue so disabled it for now

Hi,

finally I solved the problem for me. I had to adjust the Windows firewall settings. The Enable Event Message uses additional resources than the other messages.

Hi,

Can you post some screenshot what exactly you changed in Firewall

[PowerStation]

There's a NI-page for this topic: https://www.ni.com/de-de/support/documentation/supplemental/10/configuring-software-and-hardware-fir...

I think for our problem it's important to allow access  for the NIvisaic

In fact I opened the firewall for all NI applications and for those needed for VISA (searched for VISA in the firewall settings).

So I can't say which setting it was exactly that leaded to success.

In my driver package there is an "Initialize_LAN.vi" and a "Reset_LAN.vi".

There is a bug in the "Initialize_LAN.vi", the "Reset.vi" in ​​the Reset (Enable) case has to be replaced by the "Reset_LAN.vi".

Apparently the problem was already recognized by the creator of the driver, but these vi's are not displayed in the function palette.
