Data flow

The dataflow will be realized to the flow port on the receiving instance. The name of the dataflow is the name of its realized flow port and the data that has been received. For example, for the dataflow y = 1, flow port y has received the data 1.

Note that the dataflow arrow can be created through the following ways:

You can double-click the dataflow arrow to open its Features window, as shown in the following figure, from which you can, for example, choose which flow port to connect to and change the value to send.
