Updating models to work with the latest version of ACS (ACS)
The Modeler installation provides new ACS Code Generator DLLs for each language. For more information about the new ACS Code Generator DLLs and how to update any customized ACS Code Generator DLLs you are using, see the appropriate code generation section of the Modeler Help.
If you are using ACS to generate code from any of your models, upgrade the ACS profile in those models.
To update the ACS profile in a model:
1. In Modeler, open the model that contains the ACS Profile that requires updating.
2. Right-click the ACS Profile, and then click Update All Profiles.
