MLDerInit

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Initializes an derivator object.

Inputs

Input	Data Type	Range	Unit	Default	Description
BlockID	DINT	-2147483648 to 2147483647	N/A	No default	ID number of a created Pipe Block.
ModuloPosition	LREAL	No range	User units	360.0	Input ModuloPosition of Derivator object.

Outputs

Input	Data Type	Range	Unit	Description
Default (.Q)	BOOL			Returns TRUE if the Derivator object is initialized. See Pipe Network - General Rules.

Remarks

• Function block A function block groups an algorithm and a set of private data. It has inputs and outputs. 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 Motor systems having a reciprocating or oscillating motor that operates synchronously with the periodicity of the source which supplies the electrical energy. The period of execution of a pipe is the time spent between two successive computations of set values for the same pipe. The period of execution of a pipe is specified by the PERIOD parameter of the input pipe block. (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 The act of performing a sequence of instructions or commands..
  Parameters are entered directly The orientation components of a vector in space. in pop-up windows and the code is automatically added to the current project.
