Description
~~~~~~~~~~~

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

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



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
+ **number/sizes of activation inputs:** 0
+ **number/sizes of activation outputs:** 1
+ **continuous-time state:** no
+ **discrete-time state:** no
+ **object discrete-time state:** no
+ **name of computational function:** input




Example
~~~~~~~

In this example, we create a square wave generator with two inverted
outputs by using a SUPER_f block with the contents shown in the
following figure, where you can see the use of the CLKINV_f block as
event input of the internal square wave generator. `Open this example
in Xcos`_ .





The following figure shows the output of the bloc :
