multiple versions of Shared Variables on same network

[falkpl]

I have 2 seperate reactors working on the same network each deploying ~50 shared variables (different names on each process) communicating with LV 8.5RT running on FP hardware.  One of the reactors is requested for new features and to be upgraded.  Is it possible to heve 2 different shared variable engines (8.5 and 2010) and versions on the same network and client computer, or am I asking for trouble.

I'm 89.3% sure that they have to be the same. I remmber upgrading a computer to a new LabVIEW and when somebody took that computer to use as a host to an RT target, nothing would work until both computers were at the same version. It used shared variables.

Maybe someone else can confirm? Blue people?

I have been able to interoperate with small differences in versions like LV2009 and LV2010 but going back to LV 8.5 might be asking for trouble.  The underlying protocol for the SVE

was changed a few versions ago and that might be a difficult bridge to cross.

Sorry, I have no idea how I managed to post the same message twice at the same time?
