Tree view

The Tree View chapter can be used as an example for creating a project without actual hardware. All devices and components of an embedded PC must be added manually in TwinCAT 3.

The smallest possible configuration of the CX52x0 Embedded PC is created as follows in the tree view under TwinCAT 3:

Tree view 1: — CX52x0 Embedded PC in the tree view of TwinCAT 3, with attached EtherCAT Terminals (left) or Bus Terminals (right).

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

No.	Description
1	The CX52x0 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	If Bus Terminals (K-bus) are used together with a CX52x0 Embedded PC, the Bus Coupler (CX-BK) is added together with the Bus Terminals.
