Interruptable communication between Host<->RT

[DerArbeiter]

Hi,

I would like to run a cRIO as stand-alone system with optional communication to a host (PC).

The host is only used from time to time for the configuration of the cRIO and the displaying of measurement data. Most of the time it should run autark.

For the communication between Host.vi and RT.vi I would like to use shared variables, feeded by frontpanel controls via data binding property. My question is: what happens, if the host is disconnected from cRIO?. Does the cRIO still reads the shared variable (e.g. the last valid value) or is the value taken from the frontpanel control? I have to keep the cRIO running safe in this case and must be sure that there is no error thrown by the RT.vi

Hello "DerArbeiter",

if the host is diconnected from the cRIO the shared variable gives the last valid value you wrote from the host application to the RT application. After you restart the host you will be able to change that value and give it to the RT.vi

There should be no problem in doing this, a lot of our customers choose the same way.
