DNP General Options
16-bit AI
Scaling Disabled
Enabled Enabled Allows scaling 16-bit analog input
objects (see description below)
16-bit BC
Scaling
x1, x10, x100,
x1000 x1 Allows scaling 16-bit binary counter
objects (see description below)
Re-mapping
Event Points Disabled
Enabled Disabled Allows re-mapping event points starting
with point 0.
SBO Timeout 1 2-30 sec 10 Defines the Select Before Operate
(SBO) timeout when using the Control-
Relay-Output-Block object
Time Sync
Period
2
0-86400 sec 86400 Defines the time interval between
periodic time synchronization requests
Multi Fragment
Interval 5-500 ms 50 Defines the time interval between
segments of the response message
when it is fragmented
1 The Select Before Operate command causes the device to start a timer. The following
Operate command must be sent before the specified timeout value expires.
2 The device requests time synchronization by bit 4 in the first octet of the internal
indication word being set to 1 when the time interval specified by the Time Sync
Period elapses. The master should synchronize the time in the device by sending the
Time and Date object to clear this bit. The device does not send time synchronization
requests if the Time Sync Period is set to 0.
3 The total number of AI, BI and BC change event points may not exceed 64. When
you change the number of the change event points in the device, all event
setpoints are set to defaults (see Configuring DNP Event Classes below).
Scaling 16-bit AI objects
Scaling 16-bit AI objects allows accommodating native 32-bit analog input
readings to 16-bit object format; otherwise it may cause an over-range error
if the full-range value exceeds a 16-bit point limit.
Scaling is enabled by default. It is not applied to points that are read using
32-bit AI objects.
Refer to the PM172 DNP3 Reference Guide for information on the data point
scales and on a reverse conversion that should be applied to the received
scaled values.
Scaling 16-bit Binary Counters
Scaling 16-bit Binary Counters allows changing a counter unit in powers of
10 to accommodate a 32-bit counter value to 16-bit BC object format.
