DatatypeConversion

This block outputs a signal obtained by converting an input of any data type into another data type. The input and output can be any data type supported by Twin Activate.

Activate/SignalConversions

Description

The DataTypeConversion block outputs a signal obtained by converting an input of any data type into another data type. The input and output can be any data type supported by Twin Activate. In case output is integer, proper actions can be chosen to handle integer overflow and rounding.

The rounding methods "Floor", "Ceil", "Round" call corresponding OML functions, go to OML reference guide for more details.

Rounding method "Int" simply drops the fractional part of double type input.

satur

Do on overflow (for integers)

Defines the action in case of an overflow during the operation. The options are: "Nothing" (gives a normal, non saturated result), "Saturate" (gives a saturated result), "Error" (gives an error message). Default is "Nothing".

externalActivation

External activation

This parameter defines if the block receives or inherits an external activation. When External Activation is used, an additional activation port is added to the block. Default is OFF.
