9.1 WSOperatingModeEnumerationType ToC Previous Next

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
Off 1 The machine is in machine state Off.
Manual 2 All 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-automatic 4 Only 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.
Automatic 8 All 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.
