Internal Data Points of the DNP3 Driver

Direction

(seen from driver)

Configuration string for the outstation. The original value can be either

IP:<IP address>:<port number>:<link address>

for TCP/IP connections or

SI:<COM port>:<link address>

for serial connections.

Examples:

“IP:192.168.1.1:3333:10” or

“SI:COM1:10”

Allows to assign an address to a class.

<group>.<index>-<class mask>

Following options are available for the class mask parameter:

• 1 => Class 1

• 2 => Class 2

• 4 => Class 3

Example

"1.10-4" indicates: Add the Binary Input Index 10 address to the class 3.

Bit mask for execution of a general query to the corresponding device.

Bit 0 -> class 0

Bit 1 -> class 1

Bit 2 -> class 2

Bit 3 -> class 3

The value "5" means for instance that for class 2 and class 0 data a general query is executed.

With this data point element a query to a specific group can be carried out. With the variation it can be specified in which format the data should be received.

Syntax:

group:variation

Example:

To query all counter with flags (variation 1) in 32 bit modem, the entry 20:1 has to be written to the data point element.

For the group and variation numbers see Compatibility of the DNP3 Driver (Interoperability).

Executes a clear of internal indication bits in the device. The value written on the DPE is a bit mask with the following meaning:

Bit 0 -> reset “Restart” bit

Bit 1 -> reset “Need Time” bit

Bit mask to enable/disable unsolicited response.

Bit 0 -> class 1

Bit 1 -> class 2

Bit 2 -> class 3

A value "5" means for instance, that class 3 and class 1 are enabled and class 2 is disabled.

Reads out the bits of the internal indication and writes them to the data point element State.IIN, if TRUE.

The bits are updated in WinCC OA, if the value has changed (old/new comparison).

Enthält verschiedene boolesche Einstellungen. Es wird verwendet, um einige Einstellungen im Zusammenhang mit der sicheren Authentifizierung zu konfigurieren. In Zukunft kann es auch für andere boolesche Einstellungen verwendet werden.

Bit0 -> sichere Authentifizierung aktiviert(1)/deaktiviert(0)

Bit1 -> aggressiver Modus aktiviert(1)/deaktiviert(0)

Bit2 -> SHA1 erlaubt (1)/nicht erlaubt (0)

Dieses Datenpunktelement enthält die Liste der Benutzerkonfigurationen für das Gerät. In jeder Zeichenfolge werden Benutzernummer, Benutzername, Rolle und der vorinstallierte Schlüssel durch Semikolon getrennt gespeichert. Die Schlüssellänge kann entweder 16 oder 32 Byte betragen. Im Hex-Modus sind dies 32 oder 64 Zeichen.
