Post by usacodesysuser on How to connect serial devices ? ^{CODESYS Forge talk (Post)}
@eschwellinger do you have any examples of using a USB barcode scanner? I have read through the forums here and I am unable to find how to get the barcode data to populate in a text field without having to first click into the text field to activate it. Is there a library that allows you to access the barcode data? I am really new to this in general any help is greatly appreciated, hopefully you have a pretty clear example

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

Post by androidzz on Json Builder problem? ^{CODESYS Forge talk (Post)}
Dear reader, I am using the codesys JSON utilities SL, 1.9.0.0 library. And then specifically the FB JSONBuilder. I need to create a main object with at least 2 objects in it. The first object is no problem, but I cannot insert the second object into the main object. See attached my code and the result I get. I am assuming that I am doing something wrong with the parent index but have tried a lot and can't get it done. Kind regards, Rob

Post by k4zz on Continuous Build Server ^{CODESYS Forge talk (Post)}
Hallo Martin, Thank you so much for the Code example. It works really fine for .porject Types. However, I encountered a challenge when attempting to apply it to .library Types. I also tried the option to "Perform static analysis automatically after compilation" # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code() Could you please offer any insights into why this might be occurring?

Post by k4zz on Statisch Code Analyse ausführen via Python ^{CODESYS Forge talk (Post)}
Derzeit arbeite ich daran, statische Codeanalyse in unsere (CI/CD)-Pipeline zu integrieren. Konkret habe ich die statische Codeanalyse erfolgreich für .project-Typen durchgeführt, und sie funktioniert einwandfrei. Allerdings habe ich Schwierigkeiten bei der Ausführung derselben für .library-Typen festgestellt. Hierbei habe ich zwei Methoden ausprobiert: system.commands["staticanalysis", "run"].execute() # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code()

Currently, I am working on integrating static code analysis into our CI/CD pipeline. Specifically, I have successfully performed static code analysis for .project types, and it works flawlessly.

Hello, I'm using CR711S from IFM and I would like to use the CAA Can Low Level in de Safety part. I already use it on the Standard part and it works properly. I would like to know if there is some restriction on using it on the safepart of the PLC (I tried but my PCL put himself in Stop...) ? And if you have some example or even a forum with some types on IFM and CoDeSys, I would Take It. Have a nice Day.

I was looking for a transpiler from some more widely used general programming language into ST. It was not easy but I found this :) https://forge.codesys.com/tol/c2iec/home/Home/ Does anybody use it for a programm/library of a couple of hundred lines or more? How does one go about using the output? Is there a “converter” into the Codesys IDE? PLCOpenXML? Would there be interest in this? tib0r

Post by hoatran on Use third party actuator with IO-Link Master (IFM) ^{CODESYS Forge talk (Post)}
The generic sensor FB is for controlling the sensor via its cyclic input (PDI) and output (PDO). In this case, ifm raw cyclic input and output data are WORDs (16 bits total) The PDO data from the Buerkert unit are SINT (8 bits) In this case, I would use the unpackword fb from the CAA memory library to unpack the valve feed back value into the appropriate location.

Post by yannickasselin on How to sort JSON object in codesys ^{CODESYS Forge talk (Post)}
Just adding: sSubscriberdata := ''; Right before your memcopy should fix the extra characters. It is because your are copying 36 characters into a string which can contain more than 36 characters and there is garbage left in the extra characters. Regarding the parsing of json, I usually build a structure that mirrors the json data and use the available methods in the IIoT library to parse the data and fill the structure.

Post by mira on Bibliotheksentwicklung: Ältere Compiler-Version auswählen ^{CODESYS Forge talk (Post)}
Bisher war ich es gewohnt, dass ich vor dem "als übersetzte Bibliothek speichern" die Compiler-Version eingestellt habe, die mindestens erforderlich ist. In meinem aktuellen SP20-Development-System ist dies aber nicht mehr möglich. Wenn ich das Bibliotheksprojekt unter SP16 öffne, kann ich eine ältere Compiler-Version einstellen, aber ich kann die Bibliothek nicht als ".compiled-library-v3" speichern. Das "CODESYS Compiler Versions Archive" Addon ist installiert. Wie ist aktuell die Vorgehensweise für die Entwicklung von Bibliotheken mit dem Ziel auch ältere Versionen zu unterstützen?

Post by stuartjr on POU Private variables ^{CODESYS Forge talk (Post)}
Pretty sure I know the answer, but thought I would ask just in case. Is there a way to set variables declared in a POU to private so that they can not be accessed from other POUs. I tried using the library pragma, but that just stops the variables being displayed in the selection tree. My compiler version is 2.3.9.62 if that's relevant, and I'm using an ABB AC500 V2 PLC. Cheers

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?

(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?

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

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
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. Thanks for your help!
