Post by oymyakon on Modbus Lockup ^{CODESYS Forge talk (Post)}
Hi i have a project where i am communicating with many modbus devices using TCP to serial. This is all working extremely well except when i turn one of the remote devices off. If i leave the auto reconnect on it still doesn't talk to the rmianing devices and if i turn Auto reconnect off it locks up. Any help would be appreciated. Paul.

Post by tk096 on gear over gear (2 masters,1 slave) - how to do it? ^{CODESYS Forge talk (Post)}
Hi, you could calculate the position/dynamics of the slave axis yourself and use one of the function blocks SMC_FollowPosition/SMC_FollowSetValues to move the slave axis. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowPosition.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Movement/Direct/SMC_FollowSetValues.html

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 have a Codesys environment running and would like to inject code into the running environment at the same time using a code generator with Python via the console. So far I can only start a new Codesys instance with Python, but not access an already running one. How can I access the running Codesys instance?

The other one has mysteriously left. the 2nd and 3rd showed up after I restarted the program. I'm not sure how to take care of them. Please help!

I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

it seems that the device you scan, is not the same type which you have added to the project in CODESYS. Virtual Control is Arm 64 SL so please select this type in CODESYS when you generate a new Application..or right click to the device- update device - virtual Control Arm 64 SL

There is an exciting Python library that is also beyond my grasp: https://www.do-mpc.com/en/latest/index.html Step 1, get PhD(s). Step 2, get job in aerospace/robotics. Step 3, return 15 years later to share this knowledge?

Ok, this is a test programme with ADS1115. It is currently configured for the TCA9548 muxboard. If you want to run the ADS1115 single, then change the settings to the default values: ‘Is Multiplex:’ False ‘Stage mux channel numbers:’ [0,0,0,0,0,0,0,0,0] It is also important that the libraries are installed correctly here. But should be in this project

I took a look at your project. First of all, a Raspbery Pi4 is installed. You must use the GPIOs_A_B(GPIOs B+/Pi2). The error ULINT can't be set to IDINT.... with your project as well. If I change your project to ‘CODESYS_Control_for_Raspberry_Pi_SL’ the error is gone.

Post by pruwetbe on Profinet IO-link master - IODD files ^{CODESYS Forge talk (Post)}
Hello, we have the same problem here. Our configuration in the following: Codesys V3.5 SP19 running on Exor Exware700Q Profinet network connected on Eth1 IOLink Master Turck TBEN-S2-4IOL version 3.5.9.0 IOLink sensors E+H & Sick (Pressure, T°) We installed the codesys IO link package and have the codesys IO Link SL licence activated (on a dongle) Our problem is the following: we got the IODD files from E+H & Sick we add the devices in the codesys device repository with success They appear in the devices tree under IODD branch We added the TBEN IOLink master under the Profinet IO . The IO link master are ok and display online. The IO-Link SL package datasheet indicate that there would be a way to scan the IOLink device from the network but we did not find any way to trigger this scan. (we expect to get this from a right click on each IO-Link Master module but the only possibility there is "Plug device") When clicking on Plug Device, we get a browse window with profinet IO modules. The IODD devices are not there so we cannot select them. But other devices for other brands are available and can be plugged. Our question are : 1) how do we update the Profinet IO Module catalogue in order to be able to plug the E+H & Sick Sensors that we have to work with? 2) how do we activate the Scan IOLlink device that is supposed to be included in the Codesys IO-link package? 3) where can we find the manual explaining how to use this package?

Post by danwoodlock on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
Hello all, First post. I recently acquired an RPI zero W from amazon, and have been using it with Codesys v3.5 SP19 patch 2. I first got it working yesterday, and after installing the runtime on the Pi, I was prompted to install the edge gateway. Installation of the edge gateway failed because of unsupported architecture, undeterred I was able to connect to the pi and program as I wanted. The issue I've noticed is that if I do not load anything to the pi overnight, I can then no longer connect to the pi and download, although I can still ping it from my pc. I found that if I power cycle the PI, I am then able to connect again, and it works as normal. I did some googling and found instances where people recommended downloading the newest edge gateway, which brings me here. Wondering if there are any suggestions, or if this is a known issue. I actually tried installing all 3 versions of edge gateway for science, but all fail with the same message. Thanks -Dan

Post by sturmghost on Initialization of visualization variables and cyclic code execution ^{CODESYS Forge talk (Post)}
I'm looking for a smart and short way to implement initialization of visualization variables depending on the visualization input. For an easy example consider a rectangle which rests at XPos := 0 when the input state is false and at XPos := 50 when the input state is true. My visualization variables look like this: VAR_IN_OUT State : BOOL; END_VAR VAR XPos : INT; END_VAR I put this rectangle via a visualization frame element into another visualization and link a frame reference variable with the state to it. If the variable is true, the rectangle should rest at XPos := 50 and false at XPos := 0 at visualization init but how should I assign the 50 or 0 to the internal visualization variable XPos? I would need some init-methode for the visualization but I dont want a global init-method for such tasks. I want to do it inside of the visualization element but I can't see any solution for this? It would be good to be able to define ST-code within the visualization element which runs cyclic at each VISU_TASK task-cycle then I could just check the input state and change the XPos accordingly. Does someone have a solution?
