Change model parameters at runtime

Can I change model parameters during runtime in TwinCAT?

Yes, please note the following settings:

• Optimization > Default parameter behavior: Tunable
  If the parameter is set in this way, model parameters can be set at runtime. See also Parameter illustration in XAE.
• Interface > Code interface packaging
  You have the options "Nonreusable function", "Reusable function" and "C++ Class" here. The settings affect whether you can instantiate multiple instances of a TcCOM in TwinCAT and whether you can then also set their model parameters individually or dependent on each other. See also Parameterization of several module instances.
