MLAddInit

 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 Adder Pipe Block for use in a PLC Programmable Logic Controller - A digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events. Program The act of performing a sequence of instructions or commands. with user-defined settings.

Inputs

Input	Data Type	Range	Unit	Default	Description
BlockID	DINT	-2147483648 to 2147483647	N/A	No default	ID number of a created Pipe Block.
Offset1	LREAL	No range	N/A	No default	Sets the Offset value of the first entry of an Adder object.
Offset2	LREAL	No range	N/A	No default	Sets the Offset value of the second entry of an Adder object.
Ratio1	LREAL	No range	N/A	No default	Sets the Ratio value of the first entry of an Adder object.
Ratio2	LREAL	No range	N/A	No default	Sets the Ratio value of the second entry of an Adder object.

Outputs

Adder Block Output = Ratio1*Input1 + Offset1 + Ratio2*Input2 + Offset2

Output	Data Type	Range	Unit	Description
Default (.Q)	BOOL			Returns TRUE if the Adder Pipe Block is initialized. See Pipe Network - General Rules.

Remarks

• 
  

• Adder objects are normally created in the Pipe Network using the graphical engine.
  You do not have to add MLAddInit function blocks A function block groups an algorithm and a set of private data. It has inputs and outputs. to their programs.
  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.

• Function block is automatically called if an Adder Block is added to the Pipe Network.
  • User-defined settings are entered in the Pipe Blocks Properties screen.
• The Pipe Block is assigned ratios and offsets for both inputs.
  • After an Adder block is initialized, the inputs need to be selected using the MLAddWriteInput function block or graphically using the Pipe Network.
