The GMSType provides information about the Geometric Measurement System itself. It is the entry point to the OPC UA interface of a Geometric Measurement System. There is a basic structure to the interface. An instance of this type aggregates all information related to one system.
All instances of GMSType have to be referenced from the 3:Machines node defined in OPC 40001-1. At least one instance of GMSType shall be present to qualify for any profile of OPC UA for GMS.
The GMSType is formally defined in Table 12.

AbsoluteProbe indicates if the sensor provides an absolute position directly after switching on. The sensor does not need a referencing or zeroing after the start up.
Axes describes the number of available axes. The names of the axes should be descripted according to ISO 841 / ISO 10791.
Alignment describes if a sensor is fixed or flexible.
Capabilities is defined as an array of tool capabilities (e.g., single point measurement, scanning measurement, contact measurement). This value must not be changed.
The Class indicates in which mode a sensor is operated. This value must not be changed (see Table 17)
For each quantity, an EngineeringUnit is defined as reference value. A measured value is a multiple of this unit.
IsQualifiedStatus is defined as the status of the tool qualification.
The MeasuringRange defines the part of the working range for which the errors do not exceed the specified error limits. This is also called as "used range".
The Resolution indicates the smallest perceptible difference.
WorkingRange is the maximum range in which a probe can deliver values. It is normally larger than measuring range.

SensorType and MultiSensorType define a two-level structure to inform about the abilities of the available sensors on a GMS. The MultiSensorType offers the possibility of combining technically connected sensors (e.g. different sensors on a flexible carrier like an articulating carrier [ISO 10360-1]). It is not intended to provide complete information about the technical structure of all sensor components (e.g. information about each stylus of a tactile probe [ISO 10360-1]). Nevertheless it is possible to do so by defining each stylus as a sensor.
Figure 23 – Examples of sensor equipment and their representation in the OPC UA for GMS information model
Figure 23 shows two examples for GMSs with typical sensor equipment. The GMS on the left has a tactile sensor (e.g. fixed scanning sensor) and an articulating carrier described by the MultiSensorType with three further sensors, that are changeably connected to the same mount. The tactile sensor is modelled as SensorType; the MultiSensorType describing the articulating carrier combines three instances of SensorType. The GMS on the right has two sensors mounted in parallel, both are modelled as SensorTypes.

The CalibrationPrognosisType provides information about the GMS status regarding its performance. During the calibration the GMS’s errors are determined. The GMS performance is verified if the error is not greater than the specification. The information about the error is not used for correction. The GMS is not considered as a calibration target according to OPC 10000-200. Therefore a separate specification is defined here. The CalibrationPrognosisType is formally defined in Table 28.

Calibrated indicates whether the machine is calibrated or not.
CalibrationInterval is defined as the interval of time in which the machine needs a new calibration. The exact interval depends on the measuring principle and the machine utilization and is provided by the customer.
CalibrationPreptime is defined as the additional time needed to prepare a calibration considering the calibration interval to assure that the calibration expired (see Figure 24 for reference).
Figure 24 – Explanation for the difference between the calibration interval and the calibration preparation time.
DateOfCalibration is defined as the date and time when the last calibration was carried out.
CalibrationCertificate contains a reference to all available calibration certificates.
The GMSResultManagementType provides mechanisms to access results generated by the underlying GMS. Results can be managed in a local result store of the Server. Methods and Objects with Variables as well as Events and external file stores can be used to provide the results for the Client.

The CorrectionType provides information about a correction value the GMS has calculated. It is formally defined in Table 31. The value is the deviation of a characteristic value from a target value. The target value is a value the manufacturing should achieve. The correction can be used by a (tool) machine to adjust the production process. This can be, for example, the correction of a tool. Either the correction value relative or the correction value absolute must be implemented.

CorrectionValueRelative indicates how much the characteristic deviates and gives an indication to the upstream system how much the processing needs to be adjusted. The value is relative to the target value.
CorrectionValueAbsolute indicates how much the characteristic deviates and gives an indication to the upstream system how much the processing needs to be adjusted. The value is absolute to the target value.
The UpperControlLimit is the upper limit from which on a correction should be applied.
The LowerControlLimit is the lower limit from which on a correction should be applied.
Description is a human-readable description of the correction of the correction value.
ProgramName contains the name of the program.

CharacteristicIdentifier is a unique identifier of the measured characteristic.
ResultValue is the actual measurement result value.
ResultEvaluation indicates whether the result was in tolerance.
UpperToleranceLimit is the absolute upper limit where the part is still in its specification.
LowerToleranceLimit is the absolute lower limit where the part is still in its specification.
Nominal is the value given in the Geometrical Product Specification. This value indicates which theoretical value the component or the distance between two construction reference points must have (e.g., how large the bore hole must be).
CharacteristicsClass is a hint of the importance of the characteristic. The least important class is 0. Higher classes are more important. An example based on Q-DAS for the value description is given here [AQDEF 5]:
- 0 unimportant
- 1 little important
- 2 important
- 3 significant
- 4 critical
IsValid is used to mark the measured value as valid or invalid. A measurement run can be invalid within the scope of the current measurement for some reason (e.g., a hole missing in the current part). The result file could contain more information.
The Formula describes how the measurement is performed (e.g., T1-((T20-21)*0.41 + (T22-T23)*0.7))
CharacteristicType components have additional subcomponents which are defined inTable 36.
