Defines the Select Before Operate
(SBO) timeout when using the Control-
Relay-Output-Block object
Time Sync

0-86400 sec
86400
Defines the time interval between
periodic time synchronization requests

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 PM175 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.
If the scaling unit is greater than 1, the counter value is
reported being divided by the selected scaling unit from 10 to
1000. To get the actual value, multiply the counter reading by
the scaling unit.
Configuring DNP Class 0
The most common method of getting static object information
from the meter via DNP is to issue a read Class 0 request.
The PM175 allows you to configure the Class 0 response by
assigning ranges of points to be polled via Class 0 requests.
