Post by phoward131 on Text List Fallback Value ^{CODESYS Forge talk (Post)}
I am relatively new to Codesys and I'm trying to develop an HMI that displays what mode a particular device is in based on an integer value. I am currently using dynamic texts with a text list which works fine but I am looking for a way to display a particular string (ie 'Unknown') when the index doesn't match any of of the indices in the text list. I can enter 'Unknown' in the text property of the text field element which works as expected but it displays the single quotes on the visualization. How can I escape these quotes to simply display the word Unknown? Thanks!

You should use this method: VAR NULL:REFERENCE TO FB_MSG END_VAR Add_EVT_OUT REF= NULL;

as a workaround just plug your USB key to the CODESYS PC - and activate the ticket by the browser license.codesys.com

Post by fless on Warning C0564 when compiling CNC project with variables program ^{CODESYS Forge talk (Post)}
Update: We managed to avoid the warnings by changing the order of initialization by adding an attribute to the GVL with the variables. {attribute 'global_init_slot' := '49989'} The variables are initialized right before the regular GVLs (default GVL slot 49990). Note to Codesys: I see the problem, Codesys needs to initialize the CNC objects before the GVLs so they can be used in the GVL. But then you can't use variables from GVLs in CNC programs. Maybe you could disable the warning in your generated CNC objects? At least a note for a workaround would have been nice.

Post by dkugler on build (F11) / generate code using a python script file ^{CODESYS Forge talk (Post)}
thank you very much! I found the generate_code methode, but struggled with the primary and active_application. With this expample I will be able to play around. If the code generation takes a minute or more I often switch to other programs and don't notify the process is finished. So now I'll get an alert and will switch back immediately. My next little project will be, to beep different if there are errors and a seperate script to do the download incl. the user management data base without stopping at the dialogs asking for onlinechange/complete download and overwriting an existing database and as goody, play a beep/sound again.

Post by esave on OPC UA Server with on Codesys + OPC UA Client on Labview ^{CODESYS Forge talk (Post)}
Hello everyone I want a communication between my PLC as an OPC UA Server and Labview on my PC as the OPC UA Client. I have an Festo CPX-E-CEC-C1-PN PLC and I have the OPC UA Toolkit from Labview. I created some Variables for testing (see picture 1) on Codesys. I tried to use this Labview block diagram (see picture 2) but I cant connect the PLC to it. What do I have to type in the Server Endpoint URL and what in the Node ID? Is this a good way for communication with a PLC to a PC? If not is there another way?

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?
