Use Internal Signals for Debugging in RSLogix 5000 IDE

For debugging, you can generate code for test point outputs from the top-level subsystem of your model. The coder generates code that maps the test pointed output to optional AOI output parameters for RSLogix™ 5000 IDEs. In the generated code, the variable tags that correspond to the test points have the property Required=false. This example assumes that you have a model appropriately configured for the coder, such as plcdemo_simple_subsystem.

1. Open the plcdemo_simple_subsystem model.

   openExample('plcdemo_simple_subsystem');

2. In the Configuration Parameters dialog box, set Target IDE to Rockwell RSLogix 5000: AOI.

3. In the top-level subsystem of the model, right-click the output signal of SimpleSubsystem and select Properties.

   The Signal Properties dialog box is displayed.

4. On the Logging and accessibility tab, click the Test point check box.

   

5. Click OK.

6. Generate code for the top-level subsystem.

7. Inspect the generated code for the string Required=false.
