Copying license files from the dongle to the IPC

See also the notes on the working directory for license files in section Local working copy of license files.

1. Update the dongle status to ensure that TwinCAT Engineering can access the current dongle (see also Determining the current status of a license dongle).
2. To copy the license files on the license dongle into the directory c:\twincat\3.1\target\license on the target system (control computer), click Cache Dongle Licenses in the License Device window.
The license files are copied. The copies of the license files on the hard disk of the control computer have the prefix "cache..." to identify them as "cached" copies.

Make sure the checkbox Update license cache using dongle content on startup is checked so that any new license files on the dongle are automatically copied to the license working directory of the control computer when the TwinCAT Runtime is started and thus made available to the TwinCAT Runtime. When the dongle is exchanged, for example, the corresponding new license files are automatically copied to the license working directory on the control computer.

Creating a local working copy of the license file

TwinCAT 3 does not work directly with the License Response Files on the license dongle, but with a "working copy" of the files on the hard disk of the IPC (directory: c:\twincat\3.1\target\license).
