Process data transfer
Definitions
Process data telegrams between the host (master) and the controllers (slaves) are
distinguished in terms of direction as follows:
– 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"!
