6.2 PDO Transmission Types

See the following table for the explanation of PDO transmission types.
Transmission type Description Remark
0
RxPDO
The master transmits a SYNCH message to the slave every
SYNCH cycle. When there is change for RxPDO data and RxPDO
data is transmitted to the slave, the data that the slave receives is
valid after receiving the next SYNCH message. When there is no
change for RxPDO data, the master does not transmit RxPDO
data to the slave.
SYNCH
non-cyclical
TxPDO
The master transmits a SYNCH message to the slave every
SYNCH cycle. When TxPDO data changes and the slave sends
the TxPDO data to the master after receiving SYNCH message,
TxPDO data that the master receives is valid immediately.
When there is no change for TxPDO data, the slave does not
transmit TxPDO data to the master.
1~253
RxPDO
The master transmits a SYNCH message to the slave every
SYNCH cycle. The master sends out RxPDO data to the slave
once every 1~253 SYNCH cycle(s). The RxPDO data that the
slave receives from the master is valid after it receives the next
SYNCH message.
SYNCH
Cyclical
TxPDO
The master transmits a SYNCH message to the slave every
SYNCH cycle. The slave sends out TXPDO data to the master
once every time it receives 1~253 SYNCH message (s). And the
TxPDO data the master receives is valid immediately.
254
RxPDO Same as transmission type 255
ASYNCH
TxPDO Same as transmission type 255
255 RxPDO
When there is a change for RxPDO, the RxPDO data is
transmitted to the slave and the data that the slave receives is
valid immediately.
When there is no change for RxPDO, the master does not send
RxPDO data to the slave.
