TargetLink Stand-Alone Blockset

In TargetLink’s Stand-Alone Blockset, the blocks are basically just

masked Simulink blocks. Thus, their data type behavior generally

corresponds to Simulink. There are some details to note:

■ The TargetLink data type (output.type property) has no impact on

the signal type during MIL simulations. The

Cast output signal to

TargetLink type

feature is not supported.

■ Custom Code blocks behave identically in full-featured and stand-

alone mode (except that signal logging is generally not possible in

stand-alone mode).

■ TargetLink Inport and Outport blocks are always virtual. Their input

signals are simply fed through the output.

• The signal data type behavior of Index Search and Pre Look-up

Interpolation blocks is the same in full-featured and stand-

alone mode, except that in stand-alone mode, the

Cast output

signal to TargetLink type

feature is not supported.

Thus, the signal data type behavior in TargetLink stand-alone

mode does not exactly correspond to the signal data type

behavior in full-featured mode. It also does not correspond to

Simulink’s behavior , either. This might result in invalid models

after the mode has been switched.
