Labview Error 56 occurred at TCP Read

Hi, I'm just trying to run the simple "On trigger signal acquisition.vi" from the examples. I can communicate with the Red Pitaya fine by other methods, including a python script which reads data on triggers (but has other problems). The SCPI server is definitely running.

I have read this thread

viewtopic.php?f=14&t=1072&p=3742&hilit= ... read#p3742

and others, but no answers have helped. There is a waveform produced by the Read Waveform vi, which is rendered on the graph, but the error occurs regardless. If I try and run acquisition in a triggered loop, it is disrupted by the error.

Hi
Faced the same problem. I started looking at the labview sources, it's good that they are open source. So, inside the Read Waveform.vi component, there was some strange request - ACQ:SRA:HZ? (there is no description in the documentation for it, and I think that this structure does nothing useful), it is on it that error 56 occurs. If you delete everything related to this, then the error disappears.
Maybe someone from the developers will comment on this.
