Preparations for starting the sample programs (tnzip file / TwinCAT 3)

Click on the download button to save the Zip archive locally on your hard disk, then unzip the *.tnzip archive file in a temporary folder.

Select the .tnzip file (sample program).
A further selection window opens. Select the destination directory for storing the project.
For a description of the general PLC commissioning procedure and starting the program please refer to the terminal documentation or the EtherCAT system documentation.

The EtherCAT device of the example should usually be declared your present system. After selection of the EtherCAT device in the “Solutionexplorer” select the “Adapter” tab and click on “Search...”:

Checking NetId: the “EtherCAT” tab of the EtherCAT device shows the configured NetId:.
The first four numbers must be identical with the project NetId of the target system. The project NetId can be viewed within the TwinCAT environment above, where a pull down menu can be opened to choose a target system (by clicking right in the text field). The number blocks are placed in brackets there next to each computer name of a target system.
Modify the NetId: By right clicking on “EtherCAT device” within the solution explorer a context menu opens where “Change NetId...” have to be selected. The first four numbers of the NetId of the target computer must be entered; both last values are 4.1 usually.
Example:

After clicking the Download button, save the zip file locally on your hard disk, and unzip the *.tpzip -archive file into a temporary working folder.
