This tool defines some virtual device entity types with simple single-value read and write functionality. The virtual entities can be used for abstract access to device entities of different device types. The nine available virtual entities are:
- Simple Boolean Data
- Simple Boolean Data Input
- Simple Boolean Output
- Simple Integer Data
- Simple Integer Data Input
- Simple Integer Output
- Simple Decimal Data
- Simple Decimal Data Input
- Simple Decimal Output
When adding entities to a virtual device configuration they are all available from the Add menu in the virtual device setup dialog. Refer to the documentation on the Virtual Device Tool for more information.
Some of the device entities that can be used as source entities for these virtual device entities are:
- Analog input and output (Analog IO Tool)
- Digital input and output ports and channels (Digital IO Tool)
- OPC Client variables (OPC Client Tool)
All decimal data entities can have a Value Converter attached to convert one type of value to another, for example voltage to temperature.
