Trying to undestando the OutstationStackConfig

[ejs94]

I am developing a project that will need to use DNP3 and experimenting with the library on a raspberry pi. After mixing a little bit of what exists in the https://github.com/dnp3/rpi-dnp3-gpio repository with the demo outstation example. I'm using a master scada, and several extra points are consuming tags. So, how to create only binary or analog points and not all of each type? I know that the library version of the rpi repository is older, but I would like to know how to make a configuration in the current version of opendnp3.

In the main.cpp from rpi-dnp3-gpio

OutstationStackConfig stack(
        DatabaseSizes(
            config.inputs.size(), 0, 0, 0, 0,
            config.outputs.size(), 0, 0
        )
    );

In the main.cpp from outstation example

DatabaseConfig ConfigureDatabase()
{
    DatabaseConfig config(10); // 10 of each type with default settings

    config.analog_input[0].clazz = PointClass::Class2;
    config.analog_input[0].svariation = StaticAnalogVariation::Group30Var5;
    config.analog_input[0].evariation = EventAnalogVariation::Group32Var7;

    return config;
}

To create an outstation with only binary and analog points, simply call the default constructor of DatabaseConfig then fill the maps with only the points you want. Something like that:

DatabaseConfig ConfigureDatabase()
{
    DatabaseConfig config();

    config.binary_input[0] = {};
    config.binary_input[1] = {};
    config.binary_input[2] = {};

    config.analog_input[0] = {};
    config.analog_input[1] = {};
    config.analog_input[2] = {};

    return config;
}

You can of course customize the point configuration. I went with the default constructor for simplicity.
