Create TWINCAT data sources

The data source input screen opens, in which you can select the TWINCAT data source as “Type” as the first step.

However, if you first assign a name to the data source and this contains the word “twin“, “TWINCAT” is already preselected as the data source type. (This works with all data source types)

Once this has been done, the data source-specific settings of the TWINCAT data source are automatically adjusted.

TWINCAT specific

  • Connection type:
    Here you have the option of choosing between “TWINCAT2” and “TWINCAT3“. The only difference is the “port” to be used.

(TWINCAT2 = port 801 / TWINCAT3 = port 851)

  • AMS address:
    The AMS address is usually the address of the server or the address of the TWINCAT device.
  • Port:
    The port depends on the “Connection type“.

After entering the relevant information for the connection, click on “Add” or “Save” after editing a data source that has already been created.

The TWINCAT data source is created and subsequently displayed in the data source overview.

Created data sources can be edited or deleted again. You can do this using the corresponding buttons.

You also have the option of displaying all internal data sources. This works by activating the “Show internal data sources” checkbox.


In the following you can variables for the TWINCAT data source data source.
