In most applications the above procedure allows the
Device Object Instance (DE) to be established. Some
applications may request that the Device Object In-
stance (DE) be set to a given value. This can be done
through the User Interface. To do this you would use
the “DE MODIFIER ADDRESS” in conjunction with
the “DE MODIFIER OFFSET.” Using this feature
the Device Object Instance (DE) would be the (“DE
MODIFIER ADDRESS” times 100) plus “DE MODI
-
FIER OFFSET.” For example, if you wanted a DE ad-
dress of 2010 the “DE MODIFIER ADDRESS” to 20
and the “DE MODIFIER OFFSET” to 10, the Device
Object Instance (DE) is limited to a value between 0
and 4,194,303.
The “DE MODIFIER ADDRESS” and the “DE MOD-
IFIER OFFSET” are both set using the SERVICE key
of the User Interface. Go to parameter “DE MODI-
FIER ADDRESS,” press the
key to enter the DE
Modifier Address number using the numeric keypad,
and press the
key again. Navigate to parameter “DE
MODIFIER OFFSET.” Press the
key to enter the
DE Modifier Offset number using the numeric keypad
and press the
key again.
