4.16.1.2.3 Data Point Index manual default assignment rules
The DNP data point index is a sequential number assigned to a data point of a particular Object
Type. Each data point within an Object Type has a unique data point index.
•
Index rules apply to each object type independently.
•
Each physical slot has 100 points reserved in the index space.
•
Index ranges for each slot are as follows:
o
Slot 1 = 200-299
o
Slot 2 = 300-399
o
Slot 3 = 400-499
o
Slot 4 = 500-599
o
Slot 5 = 600-699
o
Slot 6 = 700-799
o
Slot 7 = 800-899
o
Slot 8 = 900-999
o
Slot 9 = 1000-1099
o
Slot 10 = 1100-1199
•
Default index ranges by slot are divided by front, rear top/right and rear bottom/left. The
divided ranges are as follows:
o
Front: n*100 + 0…63 (64 total)
o
Rear: n*100 + 64…99
Within the rear: Top/Right: 64-81 (18 total), Bottom/Left: 72-99 (18 total)
4.16.1.2.4 Data Point Index auto-assign rules
In auto implementation the data point index is assigned when the points are enabled in the point
list settings. This means that the data point indexes will change as points are enabled or disabled.
Example of auto-index numbering
: If data point 1, 3 and 5 are enabled the device will assign
these with an index of 0, 1 and 2. If data point 2 is added data point 3 and 5 will become index
2 and 3.
When using auto index assignments, a priority rule is used to sequential assign index numbers
within a point type. Priority is determined by the source of the point and the slot number and
location. The priority rules are as follows:
•
System Logic Points (SOE triggers, HMI bits)
•
Lowest Slot Number
•
Front Slot Position
•
Rear top/right to Rear bottom/left
Caution
:
Switching to manual retains the existing the auto-index assignments.
If you switch back to auto this will renumber all index assignments according to the auto-assign
rules.
