Class AbstractOpenemsModbusComponent

    • Constructor Detail

      • AbstractOpenemsModbusComponent

        protected AbstractOpenemsModbusComponent​(ChannelId[] firstInitialChannelIds,
                                         ChannelId[]... furtherInitialChannelIds)
        Default constructor for AbstractOpenemsModbusComponent.

        Automatically initializes (i.e. creates Channel instances for each given OpenemsComponent.ChannelId using the Channel-Doc.

        It is important to list all Channel-ID enums of all inherited OpenEMS-Natures, i.e. for every OpenEMS Java interface you are implementing, you need to list the interface' ChannelID-enum here like Interface.ChannelId.values().

        Use as follows: 

         public YourPhantasticOpenemsComponent() {
        super(//
                        OpenemsComponent.ChannelId.values(), //
                        YourPhantasticOpenemsComponent.ChannelId.values());
 }

        Note: the separation in firstInitialChannelIds and furtherInitialChannelIds is only there to enforce that calling the constructor cannot be forgotten. This way it needs to be called with at least one parameter - which is always at least "OpenemsComponent.ChannelId.values()". Just use it as if it was: 

         AbstractOpenemsComponent(ChannelId[]... channelIds)
        Parameters:
        firstInitialChannelIds - the Channel-IDs to initialize.
        furtherInitialChannelIds - the Channel-IDs to initialize.

                           java.lang.String modbusId)
                    throws OpenemsException
        Call this method from Component implementations activate().
        Parameters:
        context - ComponentContext of this component. Receive it from parameter for @Activate
        id - ID of this component. Typically 'config.id()'
        alias - Human-readable name of this Component. Typically 'config.alias()'. Defaults to 'id' if empty
        enabled - Whether the component should be enabled. Typically 'config.enabled()'
        unitId - Unit-ID of the Modbus target
        cm - An instance of ConfigurationAdmin. Receive it using @Reference
        modbusReference - The name of the @Reference setter method for the Modbus bridge - e.g. 'Modbus' if you have a setModbus()-method
        modbusId - The ID of the Modbus bridge. Typically 'config.modbus_id()'
        Returns:
        true if the target filter was updated. You may use it to abort the activate() method.
        Throws:
        OpenemsException - on error
