Handling Reference Data
The new PLCS RDL Editor should be used to add or update RDL. Refer to “Reference Manual” for usage of the RDL Editor. The Reference manual can be accessed either through Short cut or through the Help menu in the RDl Editor.
To add an RDL entry:
1. Load plcsrdlptc.stp present in <Windchill>\codebase\registry\stepdex\ap239\rdl using the P21 file import model from Models menu.
2. Select the relevant super type and add a “New child”. Add as many RDL entries as required.
3. Export the model to plcsrdlptc.stp file.

Model can be loaded using OWLs as well.
