# Importing a Source Batch or a Source Tightening

A Source batch or Source tightening can be exported from one controller and imported to another.

Export and Import are only possible if they are performed on the same controller, or different controllers of the same type and running the same software version.

When you import an existing Source batch or a Source tightening, any programs and modes associated with the tightening or batch sequence are also imported. These configurations are only copies and can be changed as per requirements.

1. In the Plant structure , select a controller from the list.

2. On the menu bar, select the Sources tab . The workspace area shows a list of all the current Source batches and Source tightenings.

3. Select the Add command button and select Import.

4. Select Open File and browse to select the relevant .json file.

5. Select Add.

   The new Source batch or Source Tightening will be issued the first free position in the sequence list. If there are no free slots it will be placed at the bottom of the list and assigned the lowest available index number. It is not possible to change the index number.
