Solution

Multiplexed Process Data Objects (MPDO) provide direct access to the objects of an application within a CANopen device. They are used to perform real-time transfers of small blocks of high priority data


Each MPDO message must contain one Communication Object-Identifier (COB-ID), index and subindex and two bytes of data. 

National Instruments currently does not support this feature.
