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 Programmable Logic Controller, PLC, or Programmable Controller is 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.

Returns TRUE if the Adder Pipe Block is initialized. See Function - General Rules for more information. |
Remarks
-
-
Adder objects are normally created in the Pipe Network using the graphical engine.
You do not have to add MLAddInit function blocks to their programs.
Parameters are entered directly 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.
