Hi, I have already found the solution and would like to share here and get some feedback. I downloaded and installed StartupPlusSetup_v2_70.exe (447 MB) from Phoenix Contact website. Then, I created a new project and followed the steps: 1. select device type (here: AXL F BK ETH because my bus coupler is a S20-ETH-BK), 2. choose connection type (select “Ethernet TCP/IP”), 3. select an already configured device via IP (the IP address of my bus coupler is 192.168.0.5), 4. Scan Topology > AXIOChannel > Select Generic Axioline Device Next, I added the Device "AXL F AI2 AO2 1H" from the DTM-Catalog (because my bus coupler is connected to S20-AIAO-2) and insert it under the AXIOChannel. For the next steps: Right-clicked on AXL F BK ETH --> Connect All Right-clicked on AXL F AI2 AO2 1H --> OnlineCompareAll (then i closed the message popup) Double-clicked on AXL F AI2 AO2 1H which opens up the Offline Parameter Menu Select IN2 (in my case I want to change to 4-20mA) and change the measuring range to 4 mA ... 20 mA Select OUT2 and change the Output range to 4 mA ... 20 mA Click on Apply Popup message: Do you want to write the parameter set to the device --> Select Yes Now both IN2 and OUT2 have been changed to 4-20mA!
