Yes, it makes sense. To be honest for those types of things I use AMX 
control systems, and their own programming language. I use Revolution 
as a device on my control network, but it isn't doing any of the "heavy 
lifting", it is more a data I/O system which the AMX controller 
resources for various types of data. I suppose I could send control 
commands through Rev to the AMX controller... but the native stuff does 
such a good job (and it is what my clients are actually buying) that I 
have never bothered to try. AMX stuff is also about the farthest thing 
from a low cost solution, if that is a concern – but it DOES qualify as 
a programmable logic controller.  ;-)
