Configurating the 1757-FIM 4-31
This is the preset value for the System Management set address
wait timer in 1/32 millisecond increments.
12. In the Local Clock Time Offset (LOCTIMDIFF) field, either leave
the default value of 0, or enter a new value.
This value is used to calculate the local time from the Curr App
Clock Time (CURTIME) in the number of +/- 1/32 millisecond
increments to add to the clock to obtain local time.
13. In the App Clk Sync Interval (ACSYNCINTR) field, either leave
the default value of 5, or enter a new value. See page 4-8 for
more information.
This value is the interval in seconds between time messages on
the link. System management sets it during node address
assignment.
14. In the Addr of Lnk Primary Time Pub (PTIMEPUB) field, either
leave the default value of 20, or enter a new value.
This value is the node address of the primary time publisher for
the local link. System Management sets it during node address
assignment. It is a configuration error if the SM Support
(SM_SUPPORT) parameter of the device specified by this node
address does not have the Application Clock Synchronization
feature bit set.
15. To enable the SMK (System Management Kernal) Operational
Power Up state (OPERPWRUP), click the check box next to the
field.
If the device is in the SM_OPERATIONAL state or fully
commissioned and operating when power is lost, this parameter
controls which state the SMK will enter after powerup. If
OPERPWRUP is enabled, the SMK will enter the
SM_OPERATIONAL state on powerup. If OPERPWRUP is
disabled, the SMK will enter the INITIALIZED state.
