Process Data
The data mapping of the EtherCAT network is a cyclic data exchange between the master and slave through the
CoE-based PDO mapping. The data that a slave sends to the master are packed in TxPDO and the data that the
slave reads from the master are packed in RxPDO. The inputs and outputs on the pages of Select the Outputs and
Select the Inputs contain the lists of PDOs which are available for data exchange and can be edited. For ESI file of
a device, the PDOs and PDO contents for option have been defined and some PDO contents are allowed to be
edited by users themselves as defined in ESI.
If outputs of the device are activated here (for writing), these outputs can be assigned to project variables in
the EtherCAT I/O Mapping window. And if inputs of the device are activated here (for reading), these inputs can be
assigned to project variables in the EtherCAT I/O Mapping window. It takes more PLC system resources, if you use
more PDOs.
