The LinearConverter component provides a linear conversion and its inverse, and also (optionally) allows output value clamping. The linear conversion is useful for proper scaling of values when the underlying OPC source does not directly have the desired value.

You configure the parameters of the linear conversion so that the X1 value converts to Y1, and the X2 value converts to Y2. Other values are interpolated or extrapolated according to these settings.

For values that fall outside the given limits, you can choose one of the following behaviors:

• Normal. The off-limit condition is ignored, the value is converted as usual (i.e. extrapolated, in this case).
• Error. An exception is thrown.
• Clamp. The output value is clamped at the limit.
