2.8.3 Process data object (PDO) protocol
The process data object (PDO) communication allows cyclic sending and receiving of parameters in real time.
Different transmission modes are available: synchronous, event or timer driven transmission.
Four TxPDOs and four RxPDOs are implemented:
• Receive process data object (RxPDO)
Chapter "2.8.3.1 RxPDO protocol configuration (COB-ID: 0x200, 0x300, 0x400, 0x500)", page 18
• Transmit process data object (TxPDO)
Chapter "2.8.3.4 TxPDO protocol configuration (COB-ID: 0x180, 0x280, 0x380, 0x480)", page 24

To enable receive process data object (RxPDO) transmission, the local application parameters must be
mapped to the RxPDO and a transmission type must be selected for each RxPDO channel. Four RxPDO
channels are available.
