    Nothing wrong with ladder, in a lot of applications it is simpler than ST or CFC, you're a lot less likely to have syntax issues in a ladder diagram than in structured text as long as you stick with traditional ladder elements. Your attempt was almost valid, but you tried to change the currentvisu variable using a blend of structured text and ladder, which isn't allowed. You need to use the MOVE operator and define the visualization name as a string on the input side and the visuelems.currentvisu...

    When you create a new POU be sure to choose "Ladder Logic Diagram" instead of "Ladder Logic" and you'll get all the additional toolbox items.

    Try using a password instead of a public key to log into the controller. I have a video showing how to do this on a default installation of Ubuntu server, it should work the same for Ubuntu Core. https://youtu.be/rj0dOhgnGjs?si=352PmveEP7JXZnO- I sign in to the controller at about 6:40 in the video. I have never tried to remove the public key and revert to signing in using a password, but it looks pretty straightforward https://askubuntu.com/questions/745423/how-to-turn-off-password-less-login-f...

    make sure the PLC and the programming PC have IP addresses that are on the same subnet, you'll have to know the default address of the PLC or you may need to connect to it with a special cable and use a software tool to set the IP address.

    Try using an Ethernet/IP scanner instead of an adapter, I'm guessing the 2 devices you're trying to communicate with are adapters, you have to have a scanner somewhere and Codesys should be a scanner. I don't know why you're getting the error, you should be able to use your Ethernet port as an EthernetIP adapter (although I've never had a reason to try,) but it's probably not what you wanted to do, unless you're connecting to another PLC that is a scanner. Good luck configuring the devices you're...

    Make sure the O->T and T->O bytes required by the remote device match the configuration in Codesys. Most of the EDS files I've imported have not worked by default. See the attached images for the connections and assemblies tabs. Note that the connections are in Bytes and the assemblies are in bits, you have to have enough bits to equal the bytes. Either mismatch will give a red/orange triangle. Page 343 of the manual (assuming the STF10-IP is an applied motion microstep driver) has some recommended...
