The Tree View chapter can be used as an example for creating a project without actual hardware. All
devices and components of an Embedded PCs must be added manually in TwinCAT 3.
The smallest possible configuration of the CX9020 Embedded PC is created as follows in the tree view
under TwinCAT 3:

Bus Terminals (right).
The configuration in the tree view differs depending on whether EtherCAT Terminals or Bus Terminals are
connected to the Embedded PC.

Description
1
The CX9020 Embedded PC with EtherCAT Terminals is added as
EtherCAT master. Variables for diagnostic purposes are listed under inputs
or outputs.
2
EtherCAT Terminals (E-bus) are displayed under the EK1200 Bus Coupler
in the tree view.
3
The CX9020 features NOVRAM for storing up to 128 kB of data securely. At
this point the NOVRAM handler is created, followed by configuration of the
retain variables.
