Object 1C13h: TxPDO assign (DS301)
This object is used to define the mapping for transmit direction of EtherCAT
EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs data. Either one of the fixed TxPDO mappings 1B01h to 1B26h is chosen or 1 to 4 of the free mappings 1A00h to 1A03h.
