Fig. 29: Typical configuration page of an EtherCAT Terminal
Legend:
1. The EtherCAT Terminal is inserted in the TwinCAT tree and has process data that can be linked to the PLC program.
2. View of the existing process data in bytes (exactly this number and size can be seen with PROFINET and the Siemens controller,
Siemens does not display the process data in more detail although they are described in the GSDML)
3. Display which PDOs are active in the process data
4. View of all PDOs
5. Detailed single PDOs which can be selected in "4”
6. Predefined PDOs
In the GSDML, only the predefined PDOs can be selected (6). If a different combination of PDOs is required,
this can only be done via a Beckhoff controller, such as the CX8093, which has a default PROFINET
interface and can be programmed with TwinCAT 2 (TwinCAT 3 requires a CX9020 with B930 interface, or
any Beckhoff controller with an EL6631-0010).
