Agreements
• The following distinction for process data telegrams between the host (master) and the invertes
(slaves) is made with regard to their direction:
• Process data telegrams to
the device (RPDO)
• Process data telegrams from
the device (TPDO)
• The CANopen process data objects are designated as seen from the node's view:
• Receive PDOs (RPDOx): Process data object received by a node
• Transmit PDOs (TPDOx): Process data object sent by a node
Note!
Data can only be exchanged via process data objects if the status is "Operational"!
