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 a previously created CAM Profile object 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 or Pipe Network CAM block.

Remarks
This function block is automatically called if a Profile is created in the Project Explorer with user-defined settings entered in the CAM Profile Properties screen.
- Profiles are created and initiated separately.
- The shape is modified with the CAM Editor.
- With the Editor, profiles can be changed graphically or by manually changing values in a numeric table relating input and output values with specific slopes.
- The Cam Editor software tool provides the capability to visualize, analyze, edit, and smooth profiles.
- Profile switching can be done on the fly without losing synchronization and without dead time.
- Offsets and ratios of CAM Profiles can be changed on the fly.
-
-
Profile objects are normally created in the Project Explorer.
You do not have to add MLCamInit function blocks to their programs.
Right click the Profiles folder under PLC->Motion and click Add to create a new profile.
Parameters are entered directly in a window and the code is automatically added to the current project.
-
-
Loading a Profile Editor-generated profile into a ProfileID released by MLProfileRelease should be done with care.
The MLProfileInit () function call can take in excess of 4 milliseconds to execute.
Application execution is suspended during this time until the function call is completed.
