Description

This block represent a regular input port. It must only be used inside a Xcos Super Block and be connected to a regular input in the subsystem.

This block is a signal link from outside of a system into a sub- system. In a Super Block, the regular’s input ports must be numbered from 1 to the total number of regular’s input ports. You can set it with the Port number parameter.

Data types

• Output : same type that the input connected to it in the sub-system.

Dialog box

• Port number An integer defining the port number. Properties : Type ‘vec’ of size 1.

Default properties

• always active: no
• direct-feedthrough: no
• zero-crossing: no
• mode: no
• regular outputs: - port 1 : size [-1,-2] / type -1
• number/sizes of activation inputs: 0
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: no
• object discrete-time state: no
• name of computational function: input

Example

In the following example the Super block is an amplitude modulator. The IN_f block is used as a modulation signal input. Its data type is defined by the input type of the gain block that is a scalar double data type. Open this example in Xcos .
