Note – Changes to a role after a configuration object is created do not propagate to
the configuration objects.
For example, if you create a configuration object, CODemo, that instantiates the Demo
role and then later, you add a new filter or connector to the Demo role, the CODemo
does not include this new component. To use the updated Demo role, a new
configuration object needs to be created. You can continue to use the original
CODemo configuration object or it can be deleted.
▼ To Define the RFID System Configuration Object
Configuration objects are the active entities within the RFID system. They represent
the union of the physical hardware and the software components that interact within
an RFID implementation. When you have defined your physical readers as devices
and have created the roles for your RFID system, you are ready to complete the
configuration process by defining the configuration objects.
Each time you change a Configuration Object, the RFID Event Manager must be
restarted in order for the changes to take effect. Wait until the system is completely
started or you may lose tag events. Depending on the components you used in your
role, the RFID Tag Viewer may or may not appear (it depends on the objects in your
role). The delay lets the system come up completely before generating EPC tags.
Note – Configuration objects cannot be reused for roles that have been modified. If
you modify a role, you must define a new configuration object to use that role.
