Supported MTConnect Standard

This version of the MTConnect OPC UA Server supports the MTConnect Standard 1.4.0.

The following tables list all Sample, Event and Condition data items supported by this version of the driver:

Sample Types

The sample types are subdivided into four groups, depending on the data type of the sample's value:

  • Numeric Sample Types

    Most of the MTConnect sample items expose a numeric value. This value either is a floating point value (of data type Float or Double) or an integer value (data type Int32 or UInt32).

  • Numeric 3D Sample Types

    The MTConnect sample data item PATH_POSITION represents a X/Y/Z coordinate, means this data item exposes three position values of type Double.

    Type Sub Type Data Type
    PATH_POSITION Double
    PATH_POSITION ACTUAL Double
    PATH_POSITION COMMANDED Double
    PATH_POSITION TARGET Double
    PATH_POSITION PROBE Double
  • String Sample Types

    If a sample data item exposes a value which can't be coded as numeric value the String sample type can be used. Even though the current MTConnect Standard 1.4.0 doesn't specify any string sample types, the MTConnect driver is already prepared to support this sample data type

  • DateTime Sample Types

    A few sample data items expose date, time, date and time or even time span values.

    Type Sub Type Data Type
    CLOCK_TIME DateTim

Event Types

The complete list of all supported event data items are documented in MTConnect Part 3.0 Streams Information Model Version 1.4.0, chapter 6.2 Event Element Names.

The event types are subdivided into three groups, depending on the data type of the event's value.

  • Enumeration Event Types

    All events with a limited/defined range of data values are listed in the following table. The link in the right most column (Enum type) leads to the list of valid values and their semantic.

Enumeration Types

The following tables list all enumeration types which are used for enumeration event data items. The assignment of the enumeration name to its numeric value is inspired by the OPC UA / MTConnect Companion Specification 2.0 but some of the enumeration types use deviating (more meaningful) name-value relations. All type definitions which deviate from the Companion Specification are marked with a remark 1.
