MLIntInit

Description

Initializes an integrator object. FunctionA 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. block is automatically called if an Integrator Block is added to the Pipe Network, with user-defined settings entered in the Pipe Blocks Properties screen.

Integrator object can operate in Modulo or not modulo mode. While in Modulo mode, the output values are adapted according to the entered ModuloPosition value.

• 
  

• Integrator objects are normally created in the Pipe Network using the graphical engine. Then you do not have to add MLIntInit function blocks to their programs. Parameters are entered directly in pop-up windows, and the code is then automatically added to the current project.

MLIntWriteOutVal

Description

Sets the output value of an integrator object. This function can force the output to an entered value not dependent on the input value from the Pipe Network.

• 
  

• Output value can jump to another value instantly after the function is executed if the Pipe Network is running.

• 
  

• This function or function block returns cached data. See Programming a Dual Core Controller for more information.

Arguments

Input

BlockID	Description	ID number of an initiated Integrator object
	Data type	DINT
	Range	[-2147483648, 2147483648]
	Unit	N/A
	Default	—
Value	Description	Desired new output value of the selected Integrator object
	Data type	LREAL
	Range	—
	Unit	User unit
	Default	—

Output

Default (.Q)	Description	Returns TRUE if the output value if the Integrator object is changed See more details here.
	Data type	BOOL
	Unit	N/A

Return Type

BOOL
