Value Mapping Property Extender
The Value Mapping property extender provides a mechanism that works as a lookup table for converting collected values to a different data type. This lets you do things such as map an enumerated set of string values to a corresponding set of integer values, or the other way around. The resulting values are then persisted as time-series data to track state changes over time.
Configuration
The Value Mapping property extender expects zero or more parameters. There are currently three parameters with fixed names:
| Name | Description | Default Value |

The remaining parameters are named for the input values, and their values represent the output values.
