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 50-500 ms 50 Defines the time interval between
fragments 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.
