SM_SUPPORT Bits
Any bit (of the object SM_SUPPORT) will be set that corresponds to a supported feature listed in
Table 8.23.
The resulting value in the object SM_SUPPORT is 1C1F (hex).
SM Agent Objects
Four SM agent objects are contained in the SMIB object dictionary. One object, SM_SUPPORT, was
described previously. The three other objects are timers associated with SM operations. Table 8.24
identifies the SM Agent objects with their object directory index and default values.

Object Description
SM_SUPPORT Variable that indicates the features supported by SM
in this device. See Table 8.22, Logix 3400IQ Digital
Positioner SMIB Object Dictionary
T1 Value of the SMstep timer in 1/32 of a millisecond
ticks.
T2 Value of the SM set address sequence timer in 1/32 of
a millisecond ticks.
T3 Value of the SM set address wait timer in 1/32 of a
millisecond ticks.
* The default value is specified by the communications profile for the application area
System Application Clock Time Synchronization
Each link in a fieldbus network contains an application clock time publisher responsible for distrib-
uting application time on the link.
A clock synchronization message is periodically sent by the time publisher to all fieldus devices. The
application clock time is independently maintained in each device based on its own nternal crystal clock.
Clock synchronization provides the capability for devices to time stamp data (events and alarms when
they occur).
