Converter | Signal Type | Value Type | Size Min [bit] | Size Max [bit]
--- | --- | --- | --- | ---
Standard | State | Boolean | 1 | 1
Invert | State | Boolean | 1 | 1

To avoid duplicating signals, it is possible to define Value Converters.

Converters are used to support more than one representation of the same signal (for example Angle/Torque Status can both be represented bitwise or as a status character).
