Loading TDK (TDK)
Before you can use TDK with a TDK model, you must load TDK:
• When TDK is loaded, the Load or Unload ACS button is depressed, the ACS/TDK Control toolbar displays Connected, and the ACS/TDK Log pane appears in Modeler.
• When ACS is not loaded, the Load or Unload ACS button is not depressed, the ACS/TDK Control toolbar displays Not Connected, and the ACS/TDK Log pane does not appear in Modeler.
To load TDK:
• On the ACS/TDK Control toolbar, click the Load or Unload ACS button, and wait for TDK to load.
When TDK is loaded, the ACS/TDK Control toolbar displays Connected.
After you have loaded TDK, you can create or select a Generation Settings Scheme to use to generate an ACS Code Generator DLL. How?
To unload ACS:
1. On the ACS/TDK Control toolbar, click the Load or Unload ACS button.
2. From the confirmation dialog, click Yes.
When TDK is unloaded, the ACS/TDK Control toolbar displays Not Connected.
