Data binding LN - Linear function calculation binding

The data binding LN ensures the value change of the required configurator by the control variable. The control variable is in fact the x-coordinate of the point of the specified row (see the configurator "Limit 1" and "Limit 2") and the resulting value is the y-coordinate of this point.

This data binding is obsolete (but functional) and it is better to use the E - Binding to the general expression data binding (see Example6).

Data binding configurators:
Control variableIn this field a control variable has to be defined that is usually linked to the next data binding (it can even be a constant).
Limit 1X-coordinate of the 1st point of the linear function.
Limit 2X-coordinate of the 2nd point of the linear function.
This data binding is also functional for Web panels. The evaluation of the data binding does not need to communicate with the Web server (with PROMOTIC application) - the evaluation is done on the client side (i.e. on the Web browser).
