[Dsg-hallbgas] [Dsg-mvt] MVT mass flow controller set points

[Marc McMullen]

Maxime,

I am passing this information to the Hall B Gas community. Some work was 
done to some of the mass flow controllers which are on the same cRIO as 
the MVT. The gas system has been designed with a fix for mfc related 
issues, so during some circumstances someone who is on-call may be 
required to reboot one of the cRIOs, to reset the mfc software.

Additional training needs to be conducted if this is a potential problem 
for the MVT. I will bring this up during our meeting, please talk with 
Bob and Stepan so this information is known to all.

-Marc
