Some of the objects in the POWERLINK Object Dictionary are not defined in the OPC UA Information Model of the current version of this document. However most of this objects can be accessed by the SDO Services (like ReadByIndex or WriteByIndex) provided by the PowerlinkConnectionPointType defined in 6.2.

The current specification does not allow access to DOMAIN objects that are so large that standard stack implementations cannot handle it in one single service.


-1F50h / PDL_DownloadProgData_ADOM (Firmware download)

-1F22h / CFM_ConciseDcfList_ADOM

The access to these objects will be defined in future versions of this specification. The definition should be done in alignment with future developments in the DI Working Group (OPC 10000-100).
