Post by schnepper on Minor UI bug: cannot create SFC POU after creating a Function POU ^{CODESYS Forge talk (Post)}
After creating a Function POU, it is not possible to then create an SFC POU. Steps to recreate: * Create a new Function POU. SFC is not allowed for Functions, so SFC does not show in the Implementation language dropdown. * Click Add Object -> POU... Function is selected for Type. * Select Program * SFC is not present in the Implementation language dropdown

Post by steven-schalm on Github Actions CI/CD tasks - development topic ^{CODESYS Forge talk (Post)}
hello kevinrn, I've been looking for a solution to the CI/CD issue for a long time. Briefly about me... I am 32 and software architect for Codesys V3 and fullstack dev for web (VueJS, NestJS) in a small company in Erfurt (Germany). https://www.rex-at.de/. Through my web part, we already have CI/CD running well via GitLab (YAML-based configuration file (.gitlab-ci.yml), which defines which pipelines and jobs are executed when certain events occur) with everything you know. Stages for npm packages - prepare (GitVersion, npm install or whatever) - build (vite, tsc or whatever) - testing (vitest, jest or whatever) - deploy (npm packages) And similar for monorepo's or backend services (in NestJS) as DockerImages. For Codesys we have been building an OOP framework for years (~50 libraries now), which is currently managed via SVN and a specially written Svn-Watcher (in Python) gets commits and runs and builds everything together and deploys it to an FTP server and network drive. Why do we still have SVN? Because we are unfortunately still tied to the safety integration of Codesys and can therefore only go to SP15 at most with our controller/Eckelmann. But soon there will be an update and there will be no more obstacles to using Git. Hence my questions: 1. the basic idea is to run a local Windows Runner on some machine? 2. install Codesys on the machine where the runner is running? 3. powershell & python scripts are then used to execute builds (compile, build, sign libraries) & deploys? 4. can the Github action also be used in GitLab? ChatGPT has already told me that it's not the same, but it doesn't hurt to ask. Do you have any ideas on this? Greetings :D

I think you want to implement client side scripting? Maybe creating HTML5 objects is an option, because the JavaScript is executed on the client side. See html5

Post by captaincookie on increase default string length in queue ^{CODESYS Forge talk (Post)}
I solved it by creating a new element of IElement according to the ElementExample (MyElement) in the ElementCollectionsExamples project. The variables in this element can then be defined in any properties as needed.

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

Post by tk096 on Creating Custom Kinematics ^{CODESYS Forge talk (Post)}
Hi, a few questions that you can check regarding your kinematics: * Does your kinematics FB implement the interface ISMKinematicWithInfo2? * Does AxesToCartesian(a, out f) -> CartesianToAxes(f, out aCompare) result in a=aCompare for random positions a? * Do you return a valid rotation matrix f.mR (SMC_Matrix3) in AxesToCartesian()?

Post by jeffgamsby on Accessing ModbusTCP addresses from python ^{CODESYS Forge talk (Post)}
Hi, I am new to modbusTCP and I am trying to access Input registers from codesys (3.5.SP13). The offset is 16#0000 and I am trying to access Channel 1[24] %IW24 to pull analog values. I am using pyModbusTCP and I need to supply a modbus address and the number of registers to read. What does 16#0000 mean in terms of the actual offset, how do I translate this number plus the channel to access this info via python? Any help would be appreciated, thank you.

Post by egau on Mutate Hash table value ^{CODESYS Forge talk (Post)}
Hi, using the ElementCollections Library, why isn't it possible to mutate a value found within a HashTable? From what I understand, the only way to change a value would be to use the RemoveByKey(), followed by AddKeyValuePair(). My goal is to use a Data Structure that works like a Dictionary in Python. The HashTable seems to come close to this, except that the values themselves seem to be immutable... In python, we can mutate a dict easily (see attached picture).

Post by bzzz on Connect WS2812B Light Strip to CodeSys via RasPi ^{CODESYS Forge talk (Post)}
Hey guys, I have a RasPi and can control my WS2812B (addressable light strip) via Python. The lightstrip is this one: https://core-electronics.com.au/1m-rgb-led-strip-ws2812b-144-per-meter-white-strip-weatherproof.html What I would like to do is to control it directly via CodeSys through the plc on my RasPi. I know I can run a python script on CodeSys, but I'd like to avoid doing that. Is it possible, and how do I do it? Is there a library that does this?

Post by xnoop on MBTCP Slave configuration ^{CODESYS Forge talk (Post)}
Hello, I use Codesys 3.5 SP18 Patch 4 (64 bit) My Codesys project is composed of several dozen of Modbus TCP Slaves. I want to configure each of them by define : - Modbus TCP Slave Configuration : Name, IPAddress, port - Channels - Mapping I can't afford to configure manually and I need to find automatic way What possibilities does the Codesys offer? 1. I know it possible to use python script to create Modbus TCP Master and Slave. But I don't find anyway to create Channels and Mapping through the API 2. I 've tested to set mapping with file.csv on a Modbus Tcp Slave, but no way to import channels definition from file 3. I 've tried to use PLCOpenXml file. For example I 've create a project with an Ethernet device. I've exported it in PlcOpenXml file. After delete the Ethernet device, I've imported the PlcOpenXml file without success. I've tried the same by creating Modbus TCP Slave. Could you help me to find to good way ? Thanks

Post by sangeetnenwani on Test Driver Availability in CODESYS 64-bit and Test Manager 5.1.0.0 ^{CODESYS Forge talk (Post)}
I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.
