Returns TRUE if the Derivator object is initialized. See Function - General Rules for more information. |
Remarks
Function block is automatically called if a Derivator Block is added to the Pipe Network, with user-defined settings entered in the Pipe Blocks Properties screen. Input ModuloPosition is defined to manage the periodicity (modulo) of the input values.

Derivator objects are normally created in the Pipe Network using the graphical engine.
You do not have to add MLDerInit function blocks to their programs.
Parameters are entered directly in pop-up windows and the code is automatically added to the current project.
