SRO attribute inheritance and planning the templates and instances

You can create derived templates and instances in your System Platform IDE equipment model.

When you configure any information in a derived SRO template on the Characteristic tab in the System Platform Object Editor, the configured information is automatically propagated to all the child instances of the SRO template. This saves you time in configuring the same information for different entities to capture the same characteristic results.

Note that inherited attribute values that are locked in the parent template cannot be modified in a child template or instance.

If you modify an SRO instance directly or indirectly through a template, an invalid indicator appears adjacent to the SRO icon in the System Platform IDE, which indicates that the SRO object is not synchronized with the MES database. You must run the Entity Model Builder to update the entity in the MES database as per the changes in the SRO instance.

You must deploy the System Platform IDE equipment model to use the updated entity at run time. You must also deploy the SRO OnScan to use the defined SRO configurations at run time.
