Sample program TwinCAT 3

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.

Fig.153: Opening the *. tnzip archive

• 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:
• NetId of project:       myComputer (123.45.67.89.1.1)
• Entry via „Change NetId...“:     123.45.67.89.4.1
