MasterChannelConfig

The MasterChannelConfig struct contains the following generic settings that are common to all communication channels:

• Master station address (different addresses may be used for different channels)
• Initial decoding level
• Transmit and receive buffer sizes

note

The timeout for responses is configured for each association individually. This is useful if the outstation is a gateway services with varying latency.

The constructor takes the master address and has reasonable defaults for all other settings. The default response timeout is 5 seconds; you may need to increase it for high-latency communication links. You should only need to adjust the default buffer size of 2,048 bytes if an outstation has a non-standard configuration.

Rust

fn get_master_channel_config() -> Result<MasterChannelConfig, Box<dyn std::error::Error>> {
    let mut config = MasterChannelConfig::new(EndpointAddress::try_new(1)?);
    config.decode_level = AppDecodeLevel::ObjectValues.into();
    Ok(config)
}

C

dnp3_master_channel_config_t get_master_channel_config()
{
    dnp3_master_channel_config_t config = dnp3_master_channel_config_init(1);
    config.decode_level.application = DNP3_APP_DECODE_LEVEL_OBJECT_VALUES;
    return config;
}

C++

dnp3::MasterChannelConfig config(1);
config.decode_level.application = dnp3::AppDecodeLevel::object_values;
return config;

Java

private static MasterChannelConfig getMasterChannelConfig() {
  MasterChannelConfig config = new MasterChannelConfig(ushort(1));
  config.decodeLevel.application = AppDecodeLevel.OBJECT_VALUES;
  return config;
}

C#

private static MasterChannelConfig GetMasterChannelConfig()
{
    return new MasterChannelConfig(1)
        .WithDecodeLevel(DecodeLevel.Nothing().WithApplication(AppDecodeLevel.ObjectValues));
