A slave contains a list for each of the output data types (analog and binary). These lists are to be configured depending on the desired point class and the default value of each point.

The DNP3 master can enable unsolicited responses for a specific class of points (class 1, 2, and 3).

Analog Outputs

Each data has the following parameters:

  • Point class: The point class can be 0, 1, 2 or 3.
  • Default value: The initial value that will be sent to the model until a DNP3 master connects and updates it with a new value.

Binary Outputs

Each data has the following parameters:

  • Point class: The point class can be 0, 1, 2 or 3.
  • Default value: The initial value that will be sent to the model until a DNP3 master connects and updates it with a new value.
  • Operate as trip/close pair (Binary type only): A checkbox that enables or disables the use of the point as a trip/close pair.
    When checked, the binary output will have 2 connection points, one for 'trip' and one for 'close'. The default value dictates how the 'trip or 'close' gets activated:
    • default value OFF = 'trip' or 'close' output will be active for the duration of the 'on time' parameter of the command
    • default value ON = 'trip' or 'close' output will be active for the duration of the 'off time' parameter of the command

The DNP3 master can enable unsolicited responses for a specific class of points (class 1, 2, and 3).

Connections

Once the driver has been configured as desired, the user will have to connect points in the model to points in the driver by using the designated RT-LAB GUI. This connection panel will show all the driver's and model's connectable points, once the model has been compiled. It is also possible to make connections on LabVIEW panels.

  • Only the DNP3 slave endpoint is supported.
  • The indexes of the data points correspond to the order of their definition in the driver configuration, with the first signal starting at index 0.
  • A maximum of 10 analog outputs and 10 binary outputs are supported per slave.
  • RS-232/RS-422/RS-485 and UDP communication links are not supported (TCP/IP only).
  • The supported data types are analog inputs, analog outputs, binary inputs, binary outputs, and double bit binary inputs.
  • Double bit binary input can have a value of 0, 1, 2, and 3, which are the only value that will be reflected on the DNP3 master.
  • CROB command parameters 'clear' and 'queue' are not supported.
