Post by elsmart on Sequential read and triggering of Modbs RTU channels in application ^{CODESYS Forge talk (Post)}
Hello I need some help understanding how to use Modbus RTU (COM port) in Codesys enviroment. I defined a Modbus Server device (slave) in device tree and added some channels to read from (function 3). Also I set trigering mode to Application. I have a POU in which I want to trigger each channel one after the other something like this (C code for better visualisation): for (int i = 0; i < channelsCount; i++) { triggerChannel(channelsArray[i]); // Start transmission while(channel.xBusy); // Wait for transmission to complete } I have found ModbusChannel function block documentation but examples are scarce. I don't understand how rising edge triggering works. What would be the best solution for achieving sequntial channel triggering? What is the common way to read multiple Modbus channels once every time a specified POU is executed?

Post by dkugler on Webvisu Combined Authentication ^{CODESYS Forge talk (Post)}
you are able to do this all in one screen. It is possible to set the rights of every element to visible but not editable for the user "none". so everyone is able to see this elements, but can't do any changes. At the login button you set the rights to editable for the user "none" to be able to go to the login. Every element that should be hidden before logging in, set the rights visible and editable only for "higher" users. Hint: to change rights you are able to select more then one element and edit rights for all at the same time. Saves a lot of time! Good luck!

Post by voffi on projects.open not working for file based storage project ^{CODESYS Forge talk (Post)}
Hello! Opening a project from a python script given at the CODESYS command line does not work for me with a file based storage project. Example: Running projects.open("test.project", primary = True) works but converting the project to a file based storage project and then give the folder name as an argument to project.open Running projects.open("test.fbsproj", primary = True) does not work. We decided to work with file based storage for the project. Is there a scripting API for file-based storage to e.g. convert it while running the script back or how to open file based storage project with projects.open? Thank you! voffi

Post by pernockham on Control for linux SL, 4.14.0.0 -> 4.15.0.0 breaks web page access. URL requires authentication ^{CODESYS Forge talk (Post)}
I have a problem which I have identified with a device-update from 4.14.0.0 to (4.15.0.0-4.17.0.0) where the newer versions will stop any local access to the internal web page with the browser responding "The requested URL requires authentication". Setting the device back to 4.14.0.0. the web page will respond. Access to web page through Automation server is possible also for the newer version, but not "local" access. Runtime (Codesys control for linux SL) is on 4.17.0.0. I have tried to manipulate settings for 'Access-Control-Allow-Origin' '*' always; through nginx (normally a proxy_pass to localhost:8080). Also tested bypassing nginx by accessing 8080 directly with the same result.

Post by arjunk on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
I’m trying to integrate a custom PLC into CODESYS so that it appears under the Device section. From what I understand, this requires a .devdesc.xml device descriptor file. I attempted to create the XML manually, but whenever I try to install it in order to generate a .package file, CODESYS crashes. CODESYS version: 3.5.21.20 Target PLC: Linux ARM64–based My questions are: Is there an official or easier way to generate a valid .devdesc.xml file for a custom PLC? Are there tools, templates, or examples that can help ensure the XML is structured correctly and won’t cause crashes? For Linux ARM64 targets specifically, is there a recommended starting point (e.g., modifying an existing device descriptor)? Any guidance or best practices for creating and packaging custom device descriptors would be greatly appreciated.

Post by sean-barton on Function block method default arguments ^{CODESYS Forge talk (Post)}
I have default arguments specified for function block methods but when calling a method, an error is produced requiring me to supply all the arguments despite there being default values. According to the online documentation, under section "Calling a Method" and subsection "argument passing" of the following link: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_method.html "Passing an argument for an input ... can be omitted ... for which a default or initial value was specified in the declaration..." I have found this to be the case for all Codesys IDEs I've used, 3.5.11, 3.5.16, 3.5.17, 3.5.19. Am I missing something?
