      The function returns all DPTs and DPs that contain the specified DPT as a reference.
    - dpGetStatusBit()
      Retrieves status bits.

    - dpQuery()
      Retrieves attribute values with the help of SQL statements.
    - dpQueryConnectAll()
      The function dpQueryConnectAll subscribes to attributes of configs from multiple Data Point Elements, which meet a certain query condition. When a subscribed attribute changes, a callback function (“work” function) is executed. The event manager will always send all subscribed elements, even if only one changes. Therefore update messages will always contain all subscribed elements.
    - dpQueryConnectSingle()
      The function dpQueryConnectSingle subscribes to attributes of configs from multiple Datapoint Elements, which meet a certain query condition. When a subscribed attribute changes, a callback function (“work” function) is executed. The Event Manager will send every single change separately, so update messages will normally contain only one element. If however several of the subscribed attributes are changed together within one message (i.e. in one dpSet() function call), then these will be all be forwarded in one message to the subscribing work function. Additionally, the execution of the work function can be delayed with the optional parameter blockingTime to accumulate more changes, increasing performance.
    - dpQueryDisconnect()
      Can be used to unregister work functions registered via dpQueryConnectAll() or dpQueryConnectSingle()
    - dpQuerySplit()
      Retrieves attribute values with the help of SQL statements. Use the function when you query a large amount of data. The function reduces the system load and offers a considerable advantage when dealing with a large amount of data.
