VISA close takes few seconds when using HiSLIP

[munaleipä]

Hi,

Using VISA close on HiSLIP session takes 2-3 seconds to complete. VISA close returns VI_SUCCESS so everything seems normal except for the execution time. Also communication using reads and writes is executed fast and nothing weird is going on. When using VXI-11, VISA close executes in less than a millisecond.

Is this normal or do I have something weird going on in my configuration?

Instruments are in a dedicated network with static IPs. There is only a L2 switch between the controlling computer and the instruments.

Hi munaleipä,

This is a bug in NI-VISA that happens on some HiSLIP sessions. This will be fixed in the next version.

Thanks,
