RE: Outputting a constant value

["David Dudley" <DavidDu@cctexas.com>]

Unfortunately, that didn't work.
In vdct, I can set the .VAL field to 1, but when I load the db, the VAL
field is 0.  Setting DOL to 1 causes it to have a 'CONSTANT 1' value
when you do a 'dbpr' on the field, and I have OMSL set to 'closed-loop',
however the .VAL field remains at 0.  If I do a forward link to the
block, it outputs a zero, and the .VAL remains 0.  If a do a 'dbpf' to
set the value to 1, it then works fine.  What I did as a patch around
the questionable action was to use a BI block with its DTYPE set to
'Soft Channel' and an INP of '1' that is linked to the BO, but seems
like a round-about way of doing such a simple thing.

I thought I was probably just missing something on the BO block.

David,
Can you set the DOL to '1' and use closed-loop control, rather than
the
default supervisory.

Subject: Outputting a constant value

I have a BO where every time I trigger it, I want to output a constant
value.  Since the .VAL field can't be set to a constant through vdct,
is
there an easy way to force it to have a '1' value all the time?
