About Axis Name and Number

AXIS_NUM is the same number as the one used in the PLCopen Axis Data dialog (see field Number in the PLCopen Axis Data dialog box).

The Copy function block is needed to link the Axis Number defined in the PLCopen Axis Data dialog (1 in the figure above) to the Axis Name (Axis1 in our example)

Then, this Axis Name (Axis1 in our example) is an instance of an AXIS_REF data structure that can be used in your 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 programs.
