and if you copy or transfer a project to another place, copy not only the .project, copy .compileinfo .bootinfo and .bootinfo_guids then we figured out it is more often possible to go online without full download. If you build an archiv and extract it, some of this files are missing and login isn't possible without download. I work with V3.5 SP16 Patch 4. I don't know if this problem of the archiv is solved in newer Versions/SP's and I don't know what the problem of Codesys is to help out a lot of programers of this very annoying problem or at least help with a workaround

Hello all, there is my problem. i have a project on a PC A who work properly, I aim to take this project and place it on a Pc B with a blank Codesys installed. All seemd to work, the project is created on the PC B, i create my with with online.create_online_application(project.project.active_application) recover my onlineDevice and try onlinedevice.connect() so that i can use create_live_user_management() but then a problem occure on my connect() saying gateway not configured properly. I have setted my set_credentials_for_initial_user(). when i use the Ui, there is absolutely no problem. an other question, is it possible to use the Start and Stop PLC of codesys Control Systray directly in my python script? So that if it detect that it's stopped, then he automatically start it?

Iv been working with a Deep Sea Electronics DSE840 for about 6 months. I have a development version of my program working with a state machine and a basic gui interface. I went to implement CAN and suddenly the text on the gui on the controller is much larger than before. I could flash old versions of my project and the text was the correct size, but if i renamed the project file, the text displayed would be large. The visualization in CODESYS always shows the expected size, but not the controller. I did a fresh install of CODESYS and even a new project with only one text box, I cant get the text size on the controller to match what is displayed in codesys to match. Any advice?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
