Create PLCopen Axis

To create a new PLCopenClosedA vendor -and product- independent worldwide association active in Industrial Control and aiming at standardizing PLC file formats based on XML axis, follow these steps:

  1. In the Project Explorer, right-click on the Axes folder under PLCopen and select the New Axis command in the menu

  2. Give the new axis a name the Create PLCopen Axis dialog.

  3. Fill in the axis properties by right-clicking on the new axis. See Modify PLCopen Axis for details.
  4. Compile the project to generate the code for the PLCopen axis reference(s).

    Each axis will show in the variable type PLCopenCode, which is used by the PLCopen Global variable.


  5. The PLCopen.XXXXXX_ref (MyAxis1 in the example below) is an instance of an AXIS_REF Structure that can be used in your PLCClosed"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.


  • The PLCopen axis Name and Number in the PLCopen Axis Data dialog, are automatically applied to the PLCopen instance under Global variables in the Dictionary when the project is compiled.
