AP239 / PLCS Configuration
This section describes how to configure AP239/PLCS based data exchange in Windchill.
1. Load Windchill Express schema.
2. PLCS schema-specific files can be found from the <Windchill>/codebase/registry/stepdex/ap239 folder. This is the <PLCS_HOME> folder.
3. Load the PLCS schema AP239E2_ARM_ASD_DEX_1_3_EXTENSION_lf.exp schema from the <PLCS_HOME>/schema directory. While loading the schema ensure that you have selected the “edm express extension” option.
4. Load the RDL schema, ISO_12006_3_VERSION_14.exp from the <PLCS_HOME>/rdl directory.
5. Load the following query schemas located in the <PLCS_HOME>/rdl/qex directory.
a. ifd_adapter.qex
b. ifd_wsdl_express_plcs.qex
c. define_hash_tables.qex
6. Create permanent hash tables by executing a query.
a. Navigate to Data > Query > Execute Query section in the EDMSuperviser.
b. Specify SystemRepository, DummyModel, define_hash_table, define_hash_tables as entries specific to the Repository, Model, Query Schema, and Query fields.
c. Select Ok.
7. Import the plcsrdl model from the plcsrdl.stp file located in the <PLCS_HOME>/rdl directory
8. Load import/export specific xpx files located in import/export specific folders in the <PLCS_HOME> location.
