To use the OPC UA Server feature on a cMT model, you must purchase a license from Maple Systems for every cMT model that you plan to use. Select cMT models do come with an OPC UA license already included.
This is a one-time purchase that is valid for the life of the product. After you have purchased an OPC UA license, you will receive an email from Maple Systems that contains the license serial number and activation code. You must activate the feature on the target cMT.
Refer to Tech Note 5120, "Activate an OPC-UA license on a cMT-SVR"
or the OPC-UA Set-up Overview manual for more information.
