9.6 Process data transfer

[9-6] PDO data transfer from / to the higher-level host system

For the transfer of process data, four separated process data channels (PDO1 ... PDO4) are available.

Definitions

• Process data telegrams between the host system and the devices 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"!
