Abstract
A method performed by an OPC UA client includes importing a node set file pertaining to an OPC UA-enabled automation device, the nodeset file defining validation logic used to validate data to be written to the automation device; preparing data to be written to the automation device; and using the validation logic to validate the prepared data. An alternative method includes importing a nodeset file pertaining to an automation device in which a OPC UA server is embedded, the nodeset file defining validation logic used to validate data to be written to the automation device; receiving data to be written to the automation device; and using the validation logic to validate the received data.

A method performed by an OPC UA client, the method comprising:
- importing a nodeset file pertaining to an OPC UA-enabled automation device, the nodeset file defining validation logic used to validate data to be written to the automation device;
- preparing data to be written to the automation device;
- and
- using the validation logic to validate the prepared data.
A method performed by an OPC UA server, the method comprising:
- importing a nodeset file pertaining to an automation device in which the OPC UA server is embedded, the nodeset file defining validation logic used to validate data to be written to the automation device;
- receiving data to be written to the automation device;
- and
- using the validation logic to validate the received data.
A method comprising using a control device to create a nodeset file pertaining to an OPC UA-enabled automation device, the nodeset file defining validation logic used to validate data to be written to the OPC UA-enabled automation device.
