The ToolMeasuringMachineType represents the measuring machine interface of the information model. It is the entry point to the OPC UA interface of a Tool Measuring Machine. It gives a basic structure to the interface. An instance of this type aggregates all information related to one system.

All instances of ToolMeasuringMachineType have to be referenced from the 3:Machines node defined in OPC 40001-1. At least one ToolMeasuringMachineType instance shall be present to qualify for any measuring machine profile of OPC 40504.

The ToolMeasuringMachineType is formally defined in Table 17.

The components of the ToolMeasuringMachineType have additional subcomponents which are defined in Table 18.

The 0:FileSystem is the root of all file directories of the OPC UA and the underlying machine.

Note: While a direct coupling is not essential, aligning the file paths in both OPC UA 0:FileSystem and actual file systems is recommended (e.g. "/Directory1/FileA" in Unix and "ns=1;i=1001 Directory1/FileA" in OPC UA BrowsePath). Harmonizing OPC UA 0:FileSystem with actual file systems is advised for a more intuitive and efficient work environment.
