Description

Special block similar to If-Then-Else. Input and output are synchronized. The incoming event is directed to one of the output event ports depending on the value of the regular input.

For example, when the input value is less then 2, the control input is redirected to the first command output; when the input value is between 2 and 3, the control input is redirected to the second command output; et cætera...

Arguments

• Number of output event ports

  A scalar. Number of output event ports.

  Properties : Type 'vec' of size 1

• Inherit

  If no, then it inherits the event from event input port, elseif yes, then event is activated by regular input port.

  Properties : Type 'vec' of size 1

• Zero-crossing

  Select to enable zero crossing detection.

  Properties : Type 'vec' of size 1

Default properties

• always active: no

• direct-feedthrough: yes

• zero-crossing: no

• mode: no

• regular inputs:

  - port 1 : size [1,1] / type -1

• number/sizes of activation inputs: 1

• number/sizes of activation outputs: 2

• continuous-time state: no

• discrete-time state: no

• object discrete-time state: no

• name of computational function: eselect

Interfacing function

• SCI/modules/scicos_blocks/macros/Branching/ESELECT_f.sci

Examples

Example 1

The first event port outputs when the input value is less than 2.

Example 2

Input values can be categorized using event outputs. This trigger independent data-flow with synchronous execution.
