Non-standard engineering units
HMI Process Library components can present non-standard engineering units. The table below lists such components:
Element | Name of Property/Parameter |
|---|---|
Function MTPUnitValueFormatter | customUnits |
Controls inherited from ProcessObject | Custom Units |
Service control | Custom Units |
Faceplates which present engineering units | CustomUnits |
It’s possible to set the Custom Units properties and parameters for every element individually but the most convenient way is to create, for example, an internal symbol in the HMI project, which defines all the required non-standard units, and then bind it to the corresponding properties/parameters of the elements. An example of an internal symbol and its initialization is shown below:
