Definitions for the properties of the DeviceType – OPC UA for Commercial Kitchen Equipment

5.1 Definitions for the properties of the DeviceType

Figure 6 shows an overview of the DeviceType with its Properties.

5.1.1 General

The general DeviceType from the OPC UA information model for the device configuration is taken as the basis in this specification. This information model is defined in IEC62541-100:2015.

All sub types derived from CommercialKitchenDevice can be supplemented by vendor-specific types.

5.1.2 DeviceClass property

The DeviceType defines the DeviceClass property. The classification is industry-specific and is defined for commercial kitchen devices in Table 9.

5.1.3 Manufacturer property

The manufacturer of the device is provided as freely definable text in the Manufacturer property.

5.1.4 Model property

The device designation is provided as freely definable text in the Model property.

5.1.5 SerialNumber property

The identification number, e.g. the serial number of the device, is provided as freely definable text in the SerialNumber property.

5.1.6 HardwareRevision property

The hardware version of the device is provided as freely definable text in the HardwareRevision property.

5.1.7 SoftwareRevision property

The software version of the device is provided as freely definable text in the SoftwareRevision property.

5.1.8 DeviceHealth property

The status of the device is provided as DeviceHealth enumeration in the DeviceHealth property. The possible values are NORMAL_0, FAILURE_1, CHECK_FUNCTION_2, OFF_SPEC_3 and MAINTENANCE_REQUIRED_4.

NORMAL_0	The device functions normally.
FAILURE_1	Malfunction of the device or any of its peripherals. Typically caused device-internal or process related.
CHECK_FUNCTION_2	Functional checks are currently performed. Examples: Change of configuration, local operation, substitute value entered.
OFF_SPEC_3	Off-spec means that the device is operating outside its specified range (e.g. measuring or temperature range) or that internal diagnoses indicate deviations from measured or set values due to internal problems in the device or process characteristics.
MAINTENANCE_REQUIRED_4	Although the output signal is valid, the wear reserve is nearly exhausted or a function will soon be restricted due to operational conditions e.g. build-up of deposits.
