Re: [foxboro] HART on I/A -- thoughts?

Dave,

Ed has cleared it up. My bad. Some how I got to thinking that HART was 
bi-directional.

 Terry,
Perhaps this is simply my lack of understanding.  I know you can read HART
values back on a FBM215 (like valve information).  But is the 215 a
substitute for a 214.  The 214 has the following description FBM214, HART
Inputs, 8 Channels (I/A Plant) .  The FBM 215 has the following description
FBM215, HART Output, 8 Channels.   I'm needing a card that can do inputs. 
Some channels will be HART, some will be configured 4-20ma with a non HART
device attached.  Perhaps the 215 can do this.  If so, the description on
thecards needs to change and Matt DeAthos won't have to make a new input
module, but I'm thinking that there's a reason on is called inputs and the
other is called outputs.

Regards,
David
