Licensing

The following information applies to the OPC server running on a PC platform. This information is not relevant when running on a CE platform.

TwinCAT OPC can be used free of charge as an evaluation version without a registration key for 30 days. Registration is necessary for general use. A licence for use of the software is obtained with this registration.

During the installation

When installing TwinCAT OPC, the registration key (e.g. K123-4567-8901) can be entered into the appropriate field in the setup program. This removes the time restrictions placed on the evaluation version.

If no key is available at the time of installation, please enter "DEMO" as the key. The time-limited (30 days) evaluation version of the TwinCAT OPC will be installed.

Subsequent registration of an evaluation version

Start the program TwinCAT OPC Configurator TcOpcCfg.exe and select tab "Registration".
Please enter a valid registration number into the appropriate field and pree "Register". The time limit is removed from the evaluation version.
