Device Object Instance (DE)
The unit is shipped to automatically establish the DE
address after the MAC address is established using
the MAC address switches ON the IPU or through the
User Interface. The default Device Object Instance
(DE) would be 23000 plus the MAC address. For ex-
ample, If you had a MAC address of 10 the default
Object Instance (DE) would be 23010.
The MAC address can be set in two ways using the
MAC Address Switches ON the IPU or though the
SERVICE key of the User Interface. The 8-way bi-
nary switch uses seven of the rockers to set the MAC
address. The network address must be between 1 and
127. To determine the node address, add the value of
each DIP switch in the ON position as shown in Figure
60 on page 142. Switch 8 must always be in the ON
position to allow terminal operation.

As stated above the MAC address can also be set us-
ing the SERVICE key. Go to parameter “PI MANU-
AL MAC ACCESS.” Press the  key and enter the
MAC address number using the numeric keypad and
then press the  key again. The MAC address can be
a number from 0 to 127. If the MAC address is en-
tered using the User Interface the control will ignore
any values entered through the MAC Address Switch-
es. In order to make the MAC Address switches active
again a value of –1 would need to be entered for the “PI
MANUAL MAC ACCESS.” In order to use the above
procedure to establish the Device Object Instance (DE)
the value for “DE MODIFIER OFFSET” MUST BE
SET TO –1.”
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” X 100) plus “DE MODIFI-
ER 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 then press the  key again. Then go to parameter
“DE MODIFIER OFFSET.” Press the  key to enter
the DE Modifier Offset number using the numeric key-
pad and then press the  key again.
