Assigning process data

For programs in accordance with IEC 61131-3 without IN and OUT ports

There are two ways to assign process data:

  • You can assign a process data item to a variable.
  • You can assign a variable to a process data item.

Process data is assigned in the Data List editor.

Assigning a process data item to a variable

To assign a process data item to a variable, proceed as follows:

  • Double-click the PLC node in the PLANT area.

The / PLC controller editor group opens.

  • Select the Data List editor.

You can see an overview of all available variables in the Data List editor.

You can also see an overview of all the available variables when you click on the node for the controller in the PLANT area and also open the Data List editor there. You can also assign the process data at this point.

  • To assign a process data item to a variable, click Select Process Data Item here in the Process Data Item column.

The role picker opens. Only the process data items that you can actually assign to the respective variable are displayed in the role picker.

  • In the role picker, select the process data item that you want to assign to the respective variable.

The process data item is assigned to the variable.

  • Proceed as described above to add more variables.

Assigning a variable to a process data item

To assign a variable to a process data item, proceed as follows:

  • Double-click the Axioline F (x) node in the PLANT area (for Axioline F modules).

or

  • Double-click the Profinet (x) node in the PLANT area (for PROFINET® devices).

The / Axioline F controller editor group (for PROFINET® devices: / Profinet) opens.

  • Select the Data List editor.

You can see an overview of all available process data items in the Data List editor.

The variable is assigned to the process data item.

  • Proceed as described above to add more process data items.

For programs in accordance with IEC 61131-3 with IN and OUT ports

If you have created variables as IN and/or OUT ports in your program, the process data is assigned in the Port List editor of the PLCnext node.

There are two ways to assign process data:

  • You can assign an IN port to an OUT port.
  • You can assign an OUT port to an IN port.

Opening the “Port List” editor

  • Double-click the PLCnext node in the PLANT area.

The / PLCnext editor group opens.

  • Select the Port List editor.

You can see an overview of all available IN and OUT ports in the Port List editor.

IN and OUT ports are only displayed in the Port List editor of the PLCnext node.
