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 related to points that are read
using 32-bit AI objects.
Refer to the PM130 DNP3 Reference Guide for information on the data
point scales and 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.

The Select Before Operate command causes the meter to start a timer. The
following Operate command must be sent before the specified timeout value
expires.
4 The meter 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 meter
by sending the Time and Date object to clear this bit. The meter does not send
time synchronization requests if the Time Sync Period is set to 0.

Default
Single-bit The default BI object variation for
requests with qualifier code 06 when no
specific variation is requested
16-bit-Flag The default AI object variation for
requests with qualifier code 06 when no
specific variation is requested
32-bit-Flag The default BC object variation for
requests with qualifier code 06 when no
specific variation is requested
Enabled Allows scaling 16-bit analog input
objects (see description below)
x1 Allows scaling 16-bit binary counter
objects (see description below)
10 Defines the Select Before Operate (SBO)
timeout when using the Control-Relay-
Output-Block object
Defines the time interval between
periodic time synchronization requests
50 Defines the time interval between
fragments of the response message
when it is fragmented
