DNP3 EIE – Point Types

Point Types

A device that supports DNP3 protocol has independently addressable data items, identified by point type and index. The point type and index are represented in a DNP3 device template file (.dtf) in the ptId element. The index within each point type can have a range from 0 – n.

The following table lists the point types used in devices that support DNP3 protocol.

For more specific information about point types, see the appropriate manufacturer-provided documentation.

Example

ptId ="AI.42" (Analog Input Index #42)

Note: The same index number can be used with different point types, so there can be an "AI.12" ptId and a "CT.12" ptId, but point IDs must be unique within a data group (case insensitive).
