Creating Multiplexer and Demultiplexer

When defining structured flows (in a functional definition), or structured types (in a logical definition), it is necessary to provide constructor and destructor of such flows. The functional/logical MUX (Multiplexer) and DEMUX (Demultiplexer) are used for this purpose.

This task shows you how to create the MUX and DEMUX under a function in the Functional category of RFLP structure. Note that the scenario for a logical MUX/DEMUX creation is identical (using types instead of flows).

Create MUX (Multiplexer)

The MUX considers several flows for its input and emits as output a structured flow composed of all the input flows.

From the Edition section of the action bar, click Insert a new MUX Reference.
Select the flow association you want to create the MUX for.
The Select the Flow to base the MUX/DEMUX on dialog box appears.
Two tabs are available:
- From Search: select from all available types stored in the database.
- From Session: select from available types already loaded in your session.
Browse to display available types, select the flow to base the MUX on and click OK.
The MUX is created and the selected flow is associated in emission with the MUX. Its subflows are associated in consumption with the MUX.
By default, the name of the MUX flow association is composed of the name of the association flow and subflows.
The MUX flow association is displayed in 2D representation and in the structure tree.

Create DEMUX (Demultiplexer)

The DEMUX takes, as input, one structured flow and emits, as its outputs, the subflows of the input flow.

From the Edition section of the action bar, click Insert a new DEMUX Reference.
Select the flow association you want to create the DEMUX for.
The Select the Flow to base the MUX/DEMUX on dialog box appears.
Two tabs are available:
- From Search: select from all available types stored in the database.
- From Session: select from available types already loaded in your session.
Browse to display available types, select the flow to base the DEMUX on and click OK.
The DEMUX is created and the selected flow is associated in consumption with the DEMUX. Its subflows are associated in emission with the DEMUX.
By default, the name of the DEMUX flow association is composed of the name of the association flow and subflows.

The DEMUX flow association is displayed in 2D representation and is displayed in the tree.

After creation, the MUX/DEMUX can be connected to functions.

Rotate MUX/DEMUX

You can change the direction of MUX/DEMUX 2D representation by a 90 degrees rotation either to the left or to the right using the context menu.

The result of the rotation of the MUX/DEMUX is shown in the figure below:
