Interface Channel

  • All Superinterfaces:
    ChannelRuntime, ChannelSettings
    public interface Channel
extends ChannelRuntime, ChannelSettings
    The Channel class is used to access a single data field of a communication device. A desired channel can be obtained using the DataAccessService. A channel instance can be used to
    • Access the latest record. That is the latest data record that the framework either sampled or received by listening or an application set using setLatestRecord.
    • Directly read/write data from/to the corresponding communication device.
    • Access historical data that was stored by a data logger such as SlotsDB.
    • Get configuration information about this channel such as its unit.

    Note that only the call of the read or write functions will actually result in a corresponding read or write request being sent to the communication device.
