    Anybody was able to solve this problem yet? I'm stuck with a similar issue and find no solution as --noUI is not supported for Test Manager.

    I have a project using 2 Eurotherm E+PLC controllers. They are configured using Codesys V3.5 SP17 Patch 2. For visualization I am using Codesys HMI SL V3.5.18.0. System runs great, however I found that if the E+PLC400 communications fail HMI SL does not react to it. The variables on the screen just freeze and the operator does not know it. Is there a parameter inside Codesys HMI SL I can use or create to monitor the communications between my PLC's and HMI SL so that I can create a warning message...

    Hello, I am having some troubles connecting my opc ua client to CodeSys Server with Sign or Sign & Encrypt (Basic256Sha256). If I connect with None and None it works correctly. When I first execute it shows an error BadSecurityChecksFailed, so I go to the CodeSys Server and trust my certificate. After that, when I try to connect again the servers return an BadInvalidArgument. Using WireShark I can see that I am saying something null where CodeSys does not accept, but I can find what I am sending...

    Hallo Leute, ich hätte mal eine Frage zur Verwendung des Operators NEW für die Speicherreservierung. Mit dem Operator möchte ich z.B. acht String-Speicherstellen reservieren. Die Syntax sieht dann folgendermaßen aus: psPtrToString:= NEW(STRING, 8). Der Operator erzeugt ja dann zur Laufzeit ein Array des Typs STRING. Auf die einzelnen Array-Elemente möchte ich zugreifen und Werte hineinschreiben. Wie greift man darauf zu? psPtrToString[i]:= sText scheint nicht zu funktionieren.

    You can start CODESYS and automatically run a script through the command line. See: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_starting_script_via_command_line.html Here you can find some examples, which don't answer your question, but hopefully give you more information to get started: https://content.helpme-codesys.com/en/CODESYS%20Scripting/_cds_access_cds_func_in_python_scripts.html

    Hi community, I want to open different visualizations from multiple CODESYS webservers using a reverse-proxy. Each visualization should work with the webserver's primary IP-address and a location path of the proxy. The visualization includes URL jumps to other CODESYS webservers that are accessible in the same local network. This requires replacing the content site's URL when it's opened through the proxy, as it's not possible to change the URL addresses in the PLC program. Description and Overview...
