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?

Hallo Zusammen, ich versuche die Bibliothek FloatingPointUtils.compiled-library-v3 zu benutzen. leider kommt dabei folgende Fehlermeldung: Kein Quellcode für dieses Objekt... (siehe Anhang) Wie kann ich diese Bib einbinden? Kann ich diese irgendwo herunterladen? Mein Ziel ist es ein DWORD (float) in ein REAL umzuwandeln. ICh hoffe, dass ich dies mit der Funktion HexStrToReal machen kann. So wie hier: https://gregstoll.com/~gregstoll/floattohex/ convert to float... Oder gibt es bei Codesys einen anderen Weg? Ich verwende v3.5 SP20 Patch 1 + (32Bit) Grüße Sebastian

I succeed to change the device to PI_SL but still the same problem of the I2C device switching between running and not running. the only difference with your project is that yo use I2C_master device version 4.7.0 and i 4.7.13, for GPIO i also use the 4.7.13 version and you the 4.7.0. Can you send me the older version of the Raspberry PI pheripals library, because i cannot choose lower version then 4.7.10 for the GPIO and I2C_master device

Finnaly i get it working. There was a line in the file that set the ADS1015 chip in /boot/firmware/config.txt which i removed and after that the ADS1115 has a green turning circle and i got values. i created a new component so it fits our ADS1015. see screenshot. It works also with Codesys Control for Raspberry Pi 64 SL after adding the ULINT_TO_UDINT conversion in the library. i think the chip was all the time in use by the Raspberry pi itself.

Post by annd on Migration von "CODESYS Control for PFC200 SL" zu WAGO FW26 "CODESYS V3.5.19.2" ^{CODESYS Forge talk (Post)}
Hallo, da Wago nun von eCockpit zum offenen "CODESYS Development System V3" wechselt, möchte ich meinen bestehenden 750-8212 von der PFC200 SL auf die Wago Firmware umstellen. Welche Schritte sind dabei notwendig? Den Controller würde ich auf die aktuelle FW 26 updaten und die 3.5.19.2 von Wago mit den Descriptions verwenden. Reicht es im Codesys Projektbaum mit "Gerät aktualisieren" auf den Wago Controller zu wechseln? Es wird dann statt dem "Pfc200Bus"ein leerer K-Bus und ein leerer Com-Port angezeigt. Müssen die einzelnen Module dann darunter neu angelegt und alle E/A Variablen manuell neu eingetragen werden? Das exportieren und danach wieder importieren funktioniert nicht, weil die Namen bzw. Adressen unterschiedlich sind. Ist das so richtig? Kann der Block "Modbus_COM_Port - Modbus_Master_COM_Port - Modbus_Slave" so bleiben wie bisher oder muss das auch unter dem neuen COM-Port neu angelegt werden? Für ein paar Hinweise wäre ich dankbar. Schöne Grüße, annD

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
I have a Raspberry Pi 4 we have been using for years to run CODESYS for development purposes. I recently have had to re-install the OS (Raspberry OS lite). The only change to the default configuration is not creating the "pi" user during install. I (apparently successfully) installed the 4.10.0.0 control on the Raspberry Pi. We have licences on a dongle. I am able to start the control. systemctl status shows it as running for a little while (exactly, precisely 30 seconds as per my tests, every time), then it becomes exited. I can restart the control, and the same thing happens again. Every time. In the brief moments it is running, I can log in to the PLC. Working fast and restarting the control many times, I have been able to configure users. I have been able to download my application. I have been able to run the application, and stop on a breakpoint. I have been able to connect with the licence manager and confirm the dongle is detected and licences are listed as OK. I see nothing wrong until the service just exits. I have found nothing in the logs. It is like the runtime just terminates with no error code or message after exactly 30 seconds. Any help would be appreciated.

Post by fizzy-bubblech on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Colleagues, i have the same problems. At the current time, I have to use the new version of the Codesys (3.5.20.10) + Control for Linux SL 4.11.0.0, but it works unstable : theree are a lot of freezes and not-respondings. I tested this on different projects: those that were created in the current version of the project, and those that were migrated from other versions of the development environment. Compiling a project without connecting to a controller is fast enough. The first downloading of the code into the controller, too. But as soon as you need to make edits and download a new code problems begin. Codesys "freezes" at the "Generation code" stage for 15-20 minutes. And only after that time loads the code into the controller. Previously, we used version 3.5.17.60 + Control for Linux SL 4.7.0.0. The process took 1-2 minutes. Do you have any ideas how can i fix it? I will be grateful for your answers.

Post by mikek10 on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
Hi, I have a project currently in development, it has a number of Ethernet/IP devices (18 adapter devices with Codesys as scanner, another scanner device with codesys as adapter). This has been stable whilst on factory floor for several months (though prior to that I did have some Ethernet/IP issues which were resolved by adjusting RPI rates). Today I tried updating to Ethernet /IP 4.6.0 from 4.5.1, subsequent to this I had 2 exceptions in a 2 hour period, I reverted to 4.5.1 and have had no further exceptions. Note I do have a device (Zebra printer) that frequently times out and reconnects, this does not seem to cause any issues in operation and does not cause any exceptions with 4.5.1. I believe the root cause of this is on the Zebra side, however there does not seem to be any adjustment I can make to prevent the time outs. Information from device log is in screenshot attached.

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

Post by mondinmr on First IO address of a CAADiagDeviceDefault. ^{CODESYS Forge talk (Post)}
I have a device CAADiagDeviceDefault: IoConfig_Globals.Axis_A In our library, we perform introspection of the Etc_SlaveDiag. In that case, we have connectors, and by searching for them by address, I can find them in the IO mapping using the offset and size provided by EtherCAT. However, a Lenze i700 drive, instead of placing the IO mapping in the Etc_SlaveDiag device, places it in a sub-device CAADiagDeviceDefault. So, when I perform introspection, I cannot find the IO correspondences. Yet, in the CAADiagDeviceDefault, I do not find the connectors and cannot do the matching. Is there a way with a pointer or reference to a CAADiagDeviceDefault to obtain the address of the first input and the address of the first output? This is because we have our own motion library with many EtherCAT devices that automatically configure the mappings, but I can't manage to do so with the Lenze i700.

Post by maldus512 on How to adapt Codesys Control SL to custom board ^{CODESYS Forge talk (Post)}
Hello everyone, I have been given the task to develop I/O drivers for a custom made, Linux based board to allow for Codesys applications to run and control the hardware. I have successfully installed Codesys Control SL for ARM/Linux and tested it with a simple demo application. Now I should start interfacing the runtime to the actual hardware; I should be able to interact with 2 RS485 serial ports, a few GPIOs and an I2C port, all of which already have the corresponding /dev/ interface in the Linux system. I am having trouble understanding how it should be approached. I have found sporadic references that fail to lead to a really comprehensive documentation. For example: The store page (https://store.codesys.com/en/codesys-control-for-linux-arm-sl-1.html#options) mentions a "runtime package" that should allow "Integration of existing C code" and "Usage of local I/Os", which seems exactly what I need to interact with custom peripherals. I have found no further reference to Codesys-C interpop. The Codesys Help page for the runtime package has a page on the "Development of Drivers" (https://content.helpme-codesys.com/en/CODESYS%20Control/rtsllinuxrbpdriverdevelopment.html) that suggests to either "Implement a function block" or "Implement I/O drivers". Those in turn lead to this page (https://forge.codesys.com/drv/io-drivers/doc/Generic/) which describes briefly an XML schema to describe new devices; unfortunately, it doesn't mention what to do with such a description (i.e. how does the runtime know about it) or how it is in any way connected to the actual hardware. Could anyone give me some pointers? I should also mention I have no prior experience with Codesys, so maybe I'm missing an obvious answer.

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

Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?
