9 OPC UA DataTypes

9.1 WSOperatingModeEnumerationType

This enumeration WSOperationModeEnumerationType combines machine states and operating modes of a machine. Thus, in the Weihenstephan Standards, the machine state Off is understood as an operation mode. The operating modes automatic, semi-automatic and manual are defined according to DIN IEC 60050-351. The enumeration is defined in Table 24.

The WS DataPoint WS_Cur_Mode uses the WSOperatingModeEnumerationType as data type and is defined as follows: The operating mode provides information about the way and extent of the intervention on the control equipment by the human operator. In the Weihenstephan Standards, the machine state Off is understood as an operating mode in addition to automatic, semi-automatic and manual.

Table 24 – WSOperatingModeEnumerationType Items
Name Value Description
Off1The machine is in machine state Off.
Manual2All functions of the control system are performed by humans. In connection with the Weihenstephan Standards, the step-setting mode and tipping mode are also included.
Semi-automatic4Only some of the functions of the control system are executed without human intervention. In the context of the Weihenstephan Standards, this term means that the machines of a production plant are not integrated into a control concept for the entire system and the set output is manually controlled on site.
Automatic8All functions of the control system are executed without human intervention. In the context of the Weihenstephan Standards, this term means that the machines of a production plant are integrated into a control concept for the entire plant and the set output is automatically regulated.

Its representation in the AddressSpace is defined in Table 25.

9.2 WSProgramEnumerationType

This enumeration WSProgramEnumerationType defines programs according to the Weihenstephan Standards. The WS DataPoint WS_Cur_Prog uses the WSProgramEnumerationType as data type and is defined as follows: Machine programs according to the Weihenstephan Standards.

The enumeration is defined in Table 26.

Table 26 – WSProgramEnumerationType Items
Name Value Description
Undefined (No Program)0The machine is switched on, but no program for a special application function has been selected yet or this machine is not needed.
Production1The machine functioning according to its specification.
Start Up2The machine is in the production start-up phase. This includes for example heating up or waiting for products.
Run Down4The machine is at the end of production and runs the machine empty.
Clean8A cleaning program is executed in the machine.
Changeover16The machine is changed over manually or automatically for the next product depending on parameters.
Maintenance32Maintenance and service work is performed on the machine.
Break64The machine is in a planned break.

Its representation in the AddressSpace is defined in Table 27.
