Composite Function Block
The CompositeBlock makes it possible to build new Sequencer blocks from other existing Sequencer blocks like Basic Blocks, Service Blocks and Composite Blocks.
To understand Sequencer base consepts, read also the Introduction page.
Use the MessageArgument object to forward events from/to the new CompositeBlock API. All Arguments added to the CompositeBlock API, are synchronized with each event message handled by the block.
Note: When some of the child blocks make use of cyclic processing the CompositeBlock will also use cyclic processing and synchronize the API Arguments each cycle.
Note: It is only possible to add Sequencer blocks to the CompositeBlock. When CDPOperators must be on the data path, use OperatorContainer from CDPCore instead.
