Starting up INTERBUS with logical addressing
Available on AXC F 2152 and AXC F 3152 from firmware 2019.3, and PLCnext Engineer from 2022.0 LTS
Requirements
- The AXC F XT IB is installed and the supply voltage is connected (see AXC F XT IB data sheet).
- In PLCnext Engineer:
      - A project has been created
- The IP settings have been configured
- A connection to the controller has been established
 
Adding the AXC F XT IB to your bus configuration
Selecting the AXC F XT IB
- Double-click the controller node in the PLANT area.
 ↪ The controller editor group opens.
- Select the Settings editor.
- Select the Hardware extensions view.
- From the Interbus drop-down list, select AXC F XT IB  logical addressing (2403018).
  
 ↪ The AXC F XT IB node is now displayed in the PLANT area.
   
Adding necessary libraries
- In the COMPONENTS area, open the Libraries (x) section.
- Right-click Libraries (x).
- From the context menu, select Add Library....
   
- In the file explorer that opens, select the Inline library and the PLCnext Controller library (by pressing Ctrl).
 Note: If you have created the project with a project template, the PLCnext Controller library is already added by default.
- Click the Open button.
 ↪ The two libraries are now displayed in the Libraries (x) section in the COMPONENTS area.
Adding a bus coupler
- In the PLANT area, double-click the AXC F XT IB node.
 ↪ The AXC F XT IB editor group opens.
- Select the Device List editor.
- Click Select type here in the first row of the Device List editor.
 ↪ The Role Picker opens.
  
 Note: Only those elements from the COMPONENTS area that you can actually use are displayed in the Role Picker.
- Select the relevant bus coupler in the Role Picker.
 ↪ The bus coupler is added and mapped under the AXC F XT IB (X) node in the PLANT area.
   
- To add more bus couplers, proceed as described above.
Adding I/O modules
Once you have added all the bus couplers from your bus configuration to the project, you can add the I/O modules connected to each bus coupler.
- In the PLANT area, double-click the bus coupler to which you want to add I/O modules.
 ↪ The editor group for the selected bus coupler opens (in the example: il‑bk‑1).
- Select the Module List editor.
- Click Select type here in the first row of the Module List editor.
 ↪ The Role Picker opens. Only those elements from the COMPONENTS area that you can actually use are displayed in the Role Picker.
   
- Select the relevant I/O module in the Role Picker.
 ↪ The I/O module is added and shown in the PLANT area under the AXC F XT IB (X) node for the respective bus coupler.
   
- To add more I/O modules, proceed as described above.
Completing the setup
To complete the setup of the AXC F XT IB, proceed with the instructions in the following topics:
- Programming in accordance with IEC 61131-3
- Instantiating a program
- Assigning process data
- Transferring a project to the controller
