3.2 OPC UA for Pumps and Vacuum Pumps terms

3.2.1 PumpClass

Specific type of a Pump and value of the PumpClass Variable of an instance of the FunctionalGroup Design of a Pump.

EXAMPLE 1The pump P1 is of the PumpClass positive displacement pump.
EXAMPLE 2The pump P2 is of the PumpClass turbo vacuum pump.

3.2.2 FunctionalGroup

Instance of the 2:FunctionalGroupType or one of its subtypes.

Note 1 to entry: In this specification, FunctionalGroup usually refers to an instance of a Pump specific ObjectType like OperationalGroupType, ActuationType, or DesignType.

EXAMPLE 1The pump P1 has the FunctionalGroups Identification, Design, and Operational.

3.2.3 KindOfQuantity

aspect common to mutually comparable quantities

Note 1 to entry: The division of the concept of quantity into several kinds of quantity is to some extent arbitrary. Examples:

The quantities diameter, circumference, and wavelength, are generally considered to be quantities of the same kind, namely of the kind of quantity called length.

The quantities heat, kinetic energy, and potential energy, are generally considered to be quantities of the same kind, namely of the kind of quantity called energy.

Note 2 to entry: Quantities of the same kind within a given system of quantities have the same dimension of a quantity. However, quantities of the same dimension are not necessarily of the same kind.

Examples: The quantities moment of force and energy are not of the same kind, although they have the same dimension. Similarly for heat capacity and entropy, as well as for relative permeability and mass fraction.

Note 3 to entry: The term "kind" is mainly used in expressions such as "quantities of the same kind." Two quantities of the same kind are mutually comparable, so that they can be placed in order of magnitude. Length and mass are quantities of different kinds because they are not mutually comparable.

3.2.4 Port

Connection point to a Pump used for fluids or auxiliary devices.

Note 1 to entry: Ports are described in chapter 6.2.

EXAMPLE 1The pump P1 has its process fluid inlet connected at the Port InletConnectionPort.
EXAMPLE 2The pump P1 has its drive connected at the Port DrivePort.

3.2.5 Pump

Asset of the DeviceClass Pump and representation of a pump or vacuum pump.

Note 1 to entry: This term includes all described pump types defined in this specification.

EXAMPLE 1The pump P1 has the FunctionalGroups Identification, Design, and Operational.
