'PDO Data' Editor (EtherCAT Slave Device)
The following information refers to a specific, typical device type. Your screen may differ.
This help topic describes the 'PDO Data' editor of an EtherCAT slave device in the PLANT. EtherCAT slave devices are child elements of the 'EtherCAT' node (which represents the EtherCAT Master).
The 'PDO Data' editor provides the process data objects specified in the EtherCAT slave information (ESI) file.
You can edit the PDO list by selecting/deselecting the 'Active' checkbox of particular items. (Some basic and required PDOs, however, are activated by default and cannot be deactivated.)
PDOs with a marked 'Active' checkbox are automatically inserted into the 'Data List' of the respective EtherCAT slave. In the Data List, they can be assigned to global IEC variables in your project and further processed in your application.
| Note
If the slave device is an EtherCAT bus coupler, its PDO list contains the process data of the connected I/O modules. |
