Process data transfer

[11-5] PDO data transfer from / to the higher-level host system

For transmitting process data, up to four separated process data channels (PDO1 ... PDO4) are

available depending on the device version and software version.

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"!
