SCADAPack x70 Driver Guide - Specify the DNP3 Static Group and Variation (Points and Configuration Items Supported by the Driver)

Specify the DNP3 Static Group and Variation

The DNP3 tab on the Forms of SCADAPack x70 Analog, Digital, and Counter Configuration items contains a DNP3 Static Group and Variation field. You use the field to specify the type of data that the SCADAPack x70 device sends in response to a DNP3 Class 0 (Static) data poll request from a DNP3 master. The field's options vary, depending on the point type:

Analog:

Option	Description
32-bit Analog Input (g30v1)	Sends the current value of an analog input point as a signed, 32-bit integer, in the range -2147483648 to +2147483647 where the DNP3 Master can process additional point status flags, such as overrange or underrange.
16-bit Analog Input (g30v2)	Sends the current value of an analog input point as a signed, 16-bit integer, in the range -32768 to +32767 where the DNP3 Master can process additional point status flags, such as overrange or underrange.
32-bit Analog Input No Flag (g30v3)	Sends the current value of an analog input point as a signed, 32-bit integer without status (quality) flags, in the range -2147483648 to +2147483647. Where the point does not have good quality, a group 30, variation 1 object is automatically reported for the point. This is a DNP3 protocol requirement.
16-bit Analog Input No Flag (g30v4)	Sends the current value of an analog input point as a signed, 16-bit integer without status (quality) flags, in the range -32768 to +32767. Where the point does not have good quality, a group 30, variation 2 object is automatically reported for the point. This is a DNP3 protocol requirement.
Short Float Analog Input (g30v5)	Sends the current value of an analog input point as a signed, IEEE single-precision (32-bit) floating point number with status (quality) flags.
32-bit Analog Output Status (g40v1)	Sends the current value of an analog output point as a signed, 32-bit integer with status (quality) flags. You can also use this object to notify the DNP3 Master if the point value is modified elsewhere, for example due to internal state validation and point quality.
16-bit Analog Output Status (g40v2)	Sends the current value of an analog output point as a signed, 16-bit integer with status (quality) flags. You can also use this object to notify the DNP3 Master if the point value is modified elsewhere, for example due to internal state validation and point quality.
Short Floating Point Analog Output Status (g40v3)	Sends the current value of an analog output point as a signed, IEEE single-precision (32-bit) floating point number with status (quality) flags. You can also use this object to notify the DNP3 Master if the point value is modified elsewhere, for example due to internal state validation and point quality.

Binary:

Option	Description
Binary Input (g1v1)	Sends the current state of a binary input without status (quality) flags. The minimum transmitted data size for this object is 8 bits. Eight consecutive binary input objects are the same data length as a single binary input object. To improve transmission efficiency, group binary objects together in consecutive addresses. If the point quality is not indicated as good quality, a group 1, variation 2 object is automatically reported for the point. This is a DNP3 protocol requirement.
Binary Input Status (g1v2)	Sends the current state of a binary input with status (quality) flags, when the DNP3 Master can process point status flags, for example, online, offline or downstream device communications lost.
Binary Output Status (g10v2)	Sends the current state of a binary output with status (quality) flags. You can also use this to notify the DNP3 Master if the point value is modified elsewhere, for example due to internal state validation and point quality.

Option

Description

Binary Input (g1v1)

Sends the current state of a binary input without status (quality) flags. The minimum transmitted data size for this object is 8 bits. Eight consecutive binary input objects are the same data length as a single binary input object. To improve transmission efficiency, group binary objects together in consecutive addresses.

If the point quality is not indicated as good quality, a group 1, variation 2 object is automatically reported for the point. This is a DNP3 protocol requirement.

Binary Input Status (g1v2)

Sends the current state of a binary input with status (quality) flags, when the DNP3 Master can process point status flags, for example, online, offline or downstream device communications lost.

Binary Output Status (g10v2)

Sends the current state of a binary output with status (quality) flags. You can also use this to notify the DNP3 Master if the point value is modified elsewhere, for example due to internal state validation and point quality.

Counter:

Option	Description
32-bit Binary Counter (g20v1)	Sends the current value of a counter point as an unsigned, 32-bit integer with status (quality) flags, in the range 0 to 4294967295 where the DNP3 Master can process additional point status flags, such as counter offline.
16-bit Binary Counter (g20v2)	Sends the current value of a counter point as an unsigned, 16-bit integer with status (quality) flags, in the range 0 to 65535 where the DNP3 Master can process additional point status flags, such as counter offline.
32-bit Counter No Flag (g20v5	Sends the current value of a counter point as an unsigned, 32-bit integer without status (quality) flags, in the range 0 to 4294967295. When the point does not have good quality, a group 20, variation 1 object type is automatically reported for the point. This is a DNP3 protocol requirement.
16-bit Counter No Flag (g20v6)	Sends the current value of a counter point as an unsigned, 16-bit integer without status (quality) flags, in the range 0 to 65535. When the point does not have good quality, a group 20, variation 2 object is automatically reported for the point. This is a DNP3 protocol requirement.
