Field Device Tool

The OPC UA server is a Frame Application. The Frame Application is interacting with the DTMs in order to manage the device-specific information and in order to interact with the devices. Frame Applications may support different use cases, for example: vendor-specific service, process control or asset management. Frame Applications may start and terminate the DTMs on demand (e.g. only if a value is read from the respective device).

Since the contents of the FDT project and the management of multi-client access is specific to the Frame Application, this document focuses on the mapping of the information from the DTM to the ‘Device model’ of OPC UA for Devices. One possible approach for presentation of the project information would be the ‘Device Integration Host Model’ according to OPC UA for Devices.
