Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by andrebrandt on FB string and naming ^{CODESYS Forge talk (Post)}
Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?

Post by ivanj on Codesys V3 + Rpi + PCA9685 + two robot arms ^{CODESYS Forge talk (Post)}
greetings to everyone I have a system consisting of rpi3 computer with codesys v3 installed connected to one pca9685 through which the servo motors of the two robotic arms are connected (each robot arm has 6 motors) I managed to get that the pca9685 can only drive 4 servos on the first arm the other 2 on the same robot arm do not respond, nor do the remaining 6 they do not react on the other robotic arm. Power is connected to the pca9685 for motors of sufficient power or amperage. I tried to put another pca9685 but the same thing happens again. What is the possible problem?

Post by dsa28 on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
Hello All, Hopefully I can get some help configuring an OPC UA subscriber in a CODESYS runtime in a Raspberry Pi 5 that tries to retrieve data from an OPC UA publisher (in this case running in a TwinCAT system). I tried to follow the steps described in the page to implement the OPC UA subscriber: https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_opcua_pubsub.html Seems that the example provided was created with version 3.5.16.0. Now with version 3.5.20.20 is not possible to open the complete project neither convert it. Anyway, after configuring all IPs and ports used in the OPC UA connection function block but the connection state always shows DISABLED. Can someone help me to do the proper configuration of the OPC UA subscriber? Many thanks in advance.

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hello guys, I have the following problem with the Codesys visualization (4.6.0) and Codesys V3.5.20.20. I would like to use my own HTML5 elements for my visualization. To do this, I have to select the option “Support client animations and overlay of native elements” in the visualization manager. But with the selection of this option, the visu has a massive loading delay when changing frame content. This happens even if I have not even added HTML5 elements. However, if this option is deactivated, then changing the content of the frames works without any problems, it loads instantly. I have already tried to change various refresh rates but without success. Have any of you experienced this and been able to fix it?

Post by pistola on Case Function - Multiple Conditions, Is it possible? ^{CODESYS Forge talk (Post)}
Looking at the help (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_st_instruction_case.html). I don't think it is possible but I figured I'd ask. I'm looking at have a case that evaluates two variables, instead of having multiple If Else statements I was hoping I could just use a case. Example * Case Var1 & Var 2 of 10 & 10: Instruction Code 10 & 20: Instruction Code 20 & 20: Instruction Code End_Case Obviously I tried typing as noted above and Codesys threw an error. But I was wondering if there was a different way of programming to make something like this work? If not I'll just use a bunch of If Else Statements, Thanks.

Post by sigurdrb on Codesys and error messages, warnings exceptions etc. ^{CODESYS Forge talk (Post)}
Hi, I tried some different libraries (CmpApp etc.) to find some global variables that I could read out as a variable in the codesys environment. Do any one of you know which libraries are best suited for this, and how I can read it out? My goal is to send messages, warnings etc. to the system that communicates to the PLC. Currently if something goes wrong I need to see the logfiles, or go online with the controller. I think I could save a lot of time if I could read the errors from our user interface that is connected to the PLC by TCP/IP.

Post by gatto on Undertanding Application Based Licenses ^{CODESYS Forge talk (Post)}
Hi, i think you are right. Did you press the key shopping cart? Codesys tells you the license. What I don't appreciate is that i need an additional license for communication. The system reports opc ua but this cheats you. This is communication that also concerns the tag symbols that codesys eth v3 exchanges with an operator panel. Attached is a screenshot of my case where you can see that communication opc ua is cheating you. 512 tags included in the program license are few. So, I had to buy 2 licenses. one for the program and one for communication. I don't like this policy.

Post by ellocco on Kann mich nicht am Gerät anmelden ^{CODESYS Forge talk (Post)}
CODESYS V3.5 SP18: Mit Hilfe eines anderen Forumsbeitrags von @automa konnte ich ein Problem lösen: Ich kann mich wieder beim (virtuellen) Gerät anmelden. :-) Die Lösung ist das Löschen bestimmter Dateien oder eines ganzen Ordners: Ich habe den ganzen Ordner (nachdem ich eine Sicherheitskopie angefertigt hatte) gelöscht. Es ist ein Ordner unterhalb von: c:\Users\All Users\CODESYS\CODESYSControlWinV3x64\ Es ist für mich ein wenig überraschend, den Ordner "c:\Users\All Users" kann ich bei mir gar nicht sehen und wenn ich ihn öffne, werde ich umgeleitet auf: "C:\ProgramData". Aber die andere Frage bleibt offen, wie kann ich die Sicherheitsverwaltung aktivieren?

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
Hi, When trying to activate a control Basic L license on a Wago PFC200 750-8203 the error The selected container ... does not fit your ticket comes up and won't allow licensing. I have deleted the /var/opt/codesys/cmact_license/ content 3 times and the container number changed each time after a reboot, but the problem persists. Not a happy first time experience with those weird application based licenses. IDE is 19.20. This was a e!Cockpit FW22 PLC and I used Deploy Control SL to make the green web interface red. WBM shows Codesys 2 and e!Runtime active which is a bit weird. What do I do now? Regards Heinz

Post by srouse on Adding a Softmotion License to a Weintek HMI ^{CODESYS Forge talk (Post)}
I am trying to add a Softmotion license to my Weintek HMI. The HMI is already licensed for Codesys and I have already purchased a Softmotion license as well. When using the License Manager I get an error saying the licensing info is not available. I am fairly new to working with Codesys so I am at a bit of a loss and there seems very little information online about troubleshooting this specific issue. I have attached the error message below. If there are any ideas of how to troubleshoot this better I would be happy to hear them.

Hi, ich möchte ein kleine Testaufbau viualisieren und hätte mich für den Stil "White" entschieden. nun ist es allerdings so daß dieser Stiel einige fehler beim übersetzen erzeugt. Ich habe dann versicht auf den Basic-Style zurückzugehen -- dann sind auch die Fehler weg. Leider wird dann aus der WebVisu (nur am Gerät) kein Druckknopf mehr angezeigt. Ich habe die gleichen Fehler auf 2 Codesys-Installationen (Gleicher Software Stand, 2 PCs) Kann mir da jemand weiterhelfen? ... ich Konnte den Fehler zwar nicht finden aber durch eine Komplette Deinstallation von Codesys und Übertragung der Projektdaten in ein neues Projekt ist der Fehler verschwunden. danke

Post by struccc on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hi, Might be a good idea first to try out the connection and the device with some handy software, like Modbus Poll. There you can see better, what's really going on... - Is it really connected? - What error code does it return? - Can it read from the register address? - Maybe try Input registers and Holding Registers - can make a difference - Sometimes register addresses are messed up: shifted +-1 (mixing of 2 standards) - Sometimes register addresses start with offset 30000, 40000 ... - Are you using the right protocol? - Is it RTU or TCP? Maybe ASCII? - Can even have a look at the data packets, etc... All this is easier to figure out first with some modbus utility... and then to set it up in CODESYS should not be an issue. P.

Post by milosfejgl on Codesys Licenses - How to reload them after updating the Raspberry Pi OS ^{CODESYS Forge talk (Post)}
We use several control units running on Raspberry Pi, programmed using Codesys software, with multiple licenses stored as soft containers. We are planning to update the SD card image of the Raspberry Pi to a newer OS version. However, we are concerned that this process might result in the loss of our soft container licenses. Is there a way to temporarily deactivate the license so that it can be reactivated on the updated system? Alternatively, what would be the best method to preserve the licenses during the update? Thank you in advance for any responses!

Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

I have a customer that types in machine programs in a text file for machines and lets the machine execute it. In the old situation they can open and edit these files in a winform application. Now I want to move this to codesys. What I need is a simple way to open, close, save, edit the machine file in codesys visualisation. I want to use the fileOpenSave dialog. But don't understand how it works. I have the file transfer example and some other examples. But it is hard to figure out how the part with the file dialog works so that you can select a folder or file. Does someone know how that works?

Post by eaglealex on Length of string and Array of bytes ^{CODESYS Forge talk (Post)}
Hello! I have tried read a file to the string variable. But I faced a problem - there is about 2800 bytes of information in file, but string have a limit 2393 bytes. I made two variables with same address (for automatic convertion) - string[3000] and array of bytes[1..3000]. And I noticed that array of bytes contains all information from file, but string shows only first 2393 bytes. So I have lost information. Is there really such a limitation? Or I have an error in my program and Codesys 2.3 have no limit for such kind of conversation between string and array of bytes? Thank you very much!

Liebe Forumsteilnehmer, hat jemand schon die Beckhoff-Multi-Klemme EL8601-8411 am EK1100 zusammen mit dem Raspberry Pi verwendet? Ich bin gerade am Testen und habe festgestellt - dass das mit dem Einstecken der Geräte nur teilweise funktioniert. - DI/DO und AI(U) lässt sich benutzen. - Den Zähler kann ich nicht testen, weil das Gerät nicht einsteckbar ist. Ich kann es zwar einstecken, aber dann läuft der Bus nicht. - Beim Encodereingang fehlt mir vermutlich ein geeigneter Funktionsbaustein um den zu betreiben. Gibts da evtl. irgendwo eine Bibliothek? Ich benutze CODESYS V3.5.19.70, habe die neuesten Gerätedateien (XML) von Beckhoff eingespielt und für den Raspberry Pi benutze ich die Version Codesys Control for Raspberry Pi 4.14. Für Antworten bedanke ich mich schon mal herzlich VG A. Hofer

Post by pernockham on How to manage soft container licenses for (remote) multi units? ^{CODESYS Forge talk (Post)}
Using Codesys runtime for Linux and thinking of the process of preparing multiple such systems for my customer. I don't necessarily have physical access to these units, they can be (very) remote. The idea so far is to use an image to install the Linux OS and codesys runtime. Application updates can be done by distribution of the PlcLogic/Application/application.app and application.crc files. But whats the most practical way of managing the license for these units? Do each controller need to be physically connected to a License Manager instance or can licenses be distributed by means of a license file for each unit? I believe that the license should be stored in soft containers for each unit. Help and insights appreciated! Per
