DNP3 Point Address

Introduction

Data in a DNP3 Outstation is stored in different locations depending on the intended use of the data. For example, there are separate locations for Binary Inputs, Binary Outputs, Analog Inputs and so on.

The DNP3 Point Address is a string that defines the location of data in a DNP3 Outstation. It consists of device type letters, followed by a numeric offset:

Device Type	Format
Binary Input	BI n
Binary Output	BO n
Double Bit Binary Input	DBI n
Analog Input	AI n
Analog Output	AO n
Counter	CTR n
String	STR n

Note: The numbers in DNP3 Point Addresses are zero-based.

Where Used

The DNP3 Point Address is used in these contexts:

The IOItemName property of an I/O Analog Data Point Tag when the tag is associated with a DNP3 Outstation.
The IOItemName property of a I/O Digital Data Point Tag when the tag is associated with a DNP3 Outstation.
The IOItemName property of a I/O Double Word Data Point Tag when the tag is associated with a DNP3 Outstation.
The IOItemName property of a I/O Long Word Data Point Tag when the tag is associated with a DNP3 Outstation.
The IOItemName property of a I/O String Data Point Tag when the tag is associated with a DNP3 Outstation.
The IOItemName property of a I/O Word Data Point Tag when the tag is associated with a DNP3 Outstation.
The Data-Address reference in DNP3 Data Bindings.

Data Address Editor

The Point Address Editor provides a convenient tool to build DNP3 Point Address strings.

To open the Point Address Editor, click the Browse button of the IOItemName property:

If you select the point type and enter the point number, the dialog will construct the DNP3 Point Address string.
