Chapter 10 CANopen Function and Operation
PDO Mapping and Properties
Sets the mapping parameter and transmission type for the PDO.
For more details on the function of these buttons, refer to Section 11.1.1 in the CANopen Builder
software help file.
PDO Mapping:
RxPDO1: mapping parameter P1-09; transmission type 255.
RxPDO2: mapping parameter P3-06, P4-07; transmission type 255.
TxPDO1: mapping parameter P0-09; transmission type 1.
PDO transmission type :
PDOs can be classified into RxPDO or TxPDO. RxPDO data are sent from master to slave and
TxPDO data are sent from slave to master.
The PDO transmission types can be synchronous or asynchronous. In synchronous transmission, the
master sends out the SYNC message in a fixed cycle. You set the length of the cycle in the Master
Properties dialog box (default is 50ms). In asynchronous transmission, the message is sent out when
the PDO mapping parameter changes.
The following table describes the PDO Transmission types.
