Thank you Alessio!
The PXI is running in RT mode.
The problem with having a Data Socket server on a single PC-host, and the other hosts
that Read/Write to it, is that if the PC-server crashes also the other hosts lose their
connection with the PXI... that is, the hosts are not indipendent...
if DataSocket server could be in the PXI, it would be all right,... but unfortunately this is not possible.
