Re marks
An e ditable de s cription of the obje ct's location or
function.
If the obje ct doe s not s upport intrins ic re porting, the
value will be NORMAL.
This prope rty cons is ts of the obje ct-type prope rty and the
obje ct ins tance , which is a nume ric code that ide ntifie s
the obje ct of inte re s t.
The Obje ct Name prope rty is writable whe n us ing it in
the ACM-VLX only and not in the VLX/VLX-Platinum.
TRUE de couple s the pre s e nt-value prope rty from the
phys ical output. While TRUE, the pre s e nt-value can be
change d to any value to s imulate conditions for te s ting
without affe cting the actual phys ical output.
Eithe r ACTIVE or INACTIVE. Note that a NULL value
can be writte n to the pre s e nt-value on data dis plays , but
the value is actually writte n to a priority-array prope rty.
The pre s e nt-value is the re s ult of the priority array.
Enable s you to s e t anti-cycle limits for a BO in s e conds .
This is carrie d out through priority-array inde x 6. For
e xample , by writing a value of 60 to the minimum-on-
time prope rty of a BO, you s e t a minimum ON time of 60
s e conds .
Enable s you to s e t anti-cycle limits for a BO in s e conds .
This is carrie d out through priority-array inde x 6. For
e xample , by writing a value of 60 to the minimum-off-
time prope rty of a BO, you s e t a minimum OFF time of
60 s e conds .
A re ad-only array of prioritize d value s (1-16) controlling
the pre s e nt-value , priority 1 having the highe s t priority.
The value with the highe s t priority controls the pre s e nt-
value . Pos s ible value s for priority-array inde xe s are
ACTIVE, INACTIVE, or NULL. A NULL value indicate s
no command is is s ue d at that priority le ve l.
Othe r pos s ibility is UNRELIABLE_OTHER.
De fault value us e d for pre s e nt-value prope rty whe n all
priority array value s are NULL.
A four-pos ition bit s tring that indicate s the s tatus of the
obje ct. If a s tatus bit =1, that s tatus is TRUE.
Prope rty is writable whe n us ing the ACM-VLX only and
not in the VLX/VLX-Platinum.
