Post by shubadubalu on OP UA Client - Variablen zeigen alle 0 ^{CODESYS Forge talk (Post)}
Hallo liebe Codesys Community :) Momentan versuche ich eine OPC-UA Verbindung aufzubauen, dabei habe ich ein komisches Verhalten festgestellt. Man sucht sich ja die Variablen indem man auf "Variablen aktualisieren" in Datasource klickt. Diese werden dann auch in der enstprechenden Variablenliste automatisch deklariert. Wird das Programm übertragen und die CPU (PFC200) gestartet, aktualisieren sich die Werte entsprechend. Mittels UA Expert passen die Werte aller Variablen. Starte ich jetzt die CPU neu (OPCUA Client), werden alle Variablen mit dem Wert 0 angezeigt. Unter "Allgemein und Diagnose" wird verbunden angezeigt. Auch UA Expert zeigt weiterhin die aktuellen Server Werte. Klicke ich erneut auf "Variablen aktualisieren" und übertrage das Programm funktioniert wieder alles. Ein Kalt / Warmstart hat leider keine Auswirkung. Auch den Server Neustarten bringt kein Erfolg. Wie schaffe ich es, dass die Variablen nach CPU Neustart auch die Werte des Servers annehmen? Ich freue mich über Tipps und Ideen. :) Weitere Informationen: CODESYS 64 3.5.20.50 CPU: WAGO PFC 200 750-8216 OPC UA Kommunikation Anonym und ohne Security-Strategie

Post by amani on PN Controller auf Raspberry Pi 4 ^{CODESYS Forge talk (Post)}
Hallo zusammen, Ich mache +/- erste Schritte mit RaspberryPi und Codesys: tolle Sache! Ich habe Codesys V3.5 auf einem Raspberry Pi 4 am laufen. Ich würde damit gerne einen Profinet-Slave bedienen. Die Kommunikation läuft, nun habe ich das Problem dass ich nicht verstehe wie ich den PN-Task mit dem PLC task synchron halte: Ich muss dem Slave eine Parameter-ID übergeben und beim nächsten Zyklus die Antwort auslesen. Da es dann mehrere Parameter gibt die ich nur sequentiell auslesen kann benutze ich also einen Zähler der mir die ID's durchstept. Aktuell sieht es aus als ob dieser Zähler schneller inkrementiert als der Slave antwortet (ich habe z.Bsp. 5 Parameter, diese zeigen dann alle das gleiche oder springen zwischen den Parametern). Also kurz gesagt ich muss sicherstellen dass die Datenbytes vom Slave zur gesetzten Parameter-ID passen... Ich wäre froh um ein paar Tipps! Herzlichen Dank! Grüsse, Stephan A. Wicki

Post by struccc on The future and proper use of CAA.BOLT, CAA.SEMA,.. ^{CODESYS Forge talk (Post)}
Dear All, Dear CODESYS, I'm curiously following CODESYS transitioning away from the CAA libraries, and I'm mostly in favor of these major changes. Naturally, I'd like to align my current (not end-user) developments accordingly. I'm tracking , reading release notes, ... And want to figure out the future :) Is it possible to hear / read more about the reasons, objectives and scope of these changes? One important element is CAA Types - CAA Types Extern. What is the plan with that? What's the future of CAA.SEMA, CAA.BOLT ? I have never used them (always relied on SysLib*), but they are tempting... Would be useful to have a platform independent "Macro" for this functionality... Is there something in existing or planned ? Are they suitable to be used in low level libraries... For Example IO-Drivers, Components, "to-become system libraries"? CAA.TaskLock, CAA.TaskUnlock ? Well, they don't claim platform independency, so I can't rely on those.... Any up-to-date advise, standard, pattern to follow in new libraries for task and resource locking? Practical set of conditional defines to be used? If this information is not publicly available, can you please send a private message about the proper way to achieve this? I have support agreement, just couldn't get trough with these questions... P.

Post by abuckie on i2c master not running ^{CODESYS Forge talk (Post)}
Hello, I am trying to create an Ethernet/IP device that can read analog signals, do some basic logic on it and then hand communicate the results to an Ethernet/IP master. I am using the Raspberry Pi to experiment with this as I would ultimately like to drive a display as well. I have loaded up the runtime on the Pi and got the digital I/O working. I have an ADS1115 ADC to I2C board and I can't get it to work, I get a message telling me the i2c master is not running and I am not sure where to start with this. Is there a manual for running CODESYS on the Pi or something like that I am missing? I found this post and opening the project in CODESYS V3.5 SP21 it seems like tons of this wouldn't convert properly https://forge.codesys.com/forge/talk/Runtime/thread/f1400b71b6/ I have added in the library and device manually and copied the structured text program but lost at what to do if the core functionality of the master is not running. I appreciate any help, thanks.

Post by bmatlove on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?

Hallo, Wir würden Ihre Unterstützung bei der Überprüfung der Kompatibilität der folgenden Konfiguration sehr schätzen: • PSTR-LO-16/400FEV ELMO • SCALANCE XC208 • WAGO PFC200 750-8213/40-010 • Die SPS (WAGO) wird gleichzeitig eingesetzt als: o EtherCAT-Master zur Kommunikation mit einem Elmo-Servoantrieb (EtherCAT-Slave, 4 Achsen – generisches CiA 402-Profil), und o Modbus-TCP-Server zur Kommunikation mit einem Siemens Modbus-TCP-Client, welcher zur Fernsteuerung des Elmo-Servoantriebs über die SPS dient. Bitte bestätigen Sie, ob die SPS in der Lage ist, diese Dualfunktion — als EtherCAT-Master und gleichzeitig als Modbus-TCP-Server — ohne Konflikte oder Performanceprobleme zu unterstützen. Insbesondere interessiert uns, ob die CODESYS SoftMotion SL Basislizenz (2305000000-F) notwendig ist, um 4 Servoachsen zu steuern, und ob diese Lizenz auf einer WAGO PFC200 SPS mit CODESYS Version 3.5 Service Pack 19 Patch 40 oder höher unterstützt wird. Alle Achsen im Servoantrieb werden unabhängig voneinander gesteuert. Mit freundlichen Grüßen. ILIYA

Most configurations I have come across impose static MB configs in which all configured devices MUST be present and functional... I have monkeyed around with MB enough to know that herding a half dozen MB cats into a working config can be tricky. I just do them one at a time and dynamically turn them on/off in whatever combination is convenient with ID, IP, baud, parity etc being runtime tweakable. I am totally curious whether this is possible with codesys, or whether its device configuration corrals one into a static cage which requires re-building the code to support flexible variations.

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
Looking for thoughts on creating libraries that can be used on both 32-bit and 64-bit controllers. We are currently writing software in CoDeSys for both target types and will continu to do so for the near future. Projects are always unique, no straight forward copy/paste, yet there is enough similarity between them to use libraries for recurring logic. I do not want to create and maintain twice for both platforms if this is not absolutely necessary. I am aware of useful datatypes like __XWORD, __XINT, __UXINT. Still looking for more information and/or sample code for portable pointer arithmetic. In addition to that: how should one go about when creating and working with compiled libraries? Would I need to compile the same lib twice, once for 32-bit targets once for 64-bit targets? I would end up with two different libs with the same namespace, which does not sound elegant to me. Note: I did not intentionally make the previous paragraph bold. The forge forum software seems to do this automatically upon insertion of a word which starts with two underscores, e.g. __XWORD (yeah, here we go again :) )

Post by marsmaennchen on MQTT,mehrere Topics publish/subscribe ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe im Grunde dieselbe Frage wie in diesem Thread: https://forge.codesys.com/forge/talk/Deutsch/thread/85372a6daf/ Leider hat der Threadersteller das Problem selbst gelöst, ohne seine Lösung zu teilen. Mein Setup: Ich möchte von einer WAGO PFC200 Daten per MQTT an HomeAssistant übertragen. Die Grundkommunikation steht bereits. Angenommen, man hat 50 Lichtschalter und 50 Lampen. Wie ist das übliche Vorgehen, um 50 einzelne Bool-Werte (Lichtschalter ein/aus) effizient zu übertragen? Ich finde einfach kein Beispiel, das ich als Vorlage nutzen könnte. Muss wirklich für jeden Lichtschalter ein eigenes MQTT-Topic und somit ein eigener Baustein in CODESYS angelegt werden? Also z. B. Topic/LS1/state, Topic/LS2/state usw.? Oder gibt es eine gängige, professionellere Methode, mehrere Schalter effizient zu übertragen? Zur Eingrenzung: Ich nutze die CODESYS IIoT Libraries, da die Janz Tec MQTT Library für mich bisher zu komplex ist. Kann mir jemand bitte erklären, wie Profis so etwas lösen? Vielen Dank schon mal für eure Tipps! Gruß Patrick

Hello, I've been trying to use EoE for communication between a Windows PC and an M753 drive from Control Technique. Despite following some online guides (https://content.helpme-codesys.com/en/libs/EtherCATStack/4.3.0.0/Ethernet_over_EtherCAT/fld-Ethernet_over_EtherCAT.html) I haven’t had any success. Both are connected to a Debian device where RTE is running: The PC is connected via the Ethernet port. The drive is connected via the EtherCAT port. I'm unable to ping the drive from my Windows PC. Here is my configuration: On Debian: (See attachments 1, 2, 3) enp1s0 = Ethernet port enp2s0 = EtherCAT port tap2 = TAP device IP forwarding and routes are both configured. On Windows: (See attachments 4, 5) On Codesys: (See attachments 6, 7) Version: Windows 11 Debian GNU/Linux 11 Codesys 3.5.17 Control for Linux SL 4.7.0 EtherCAT 4.4.0 With this configuration, I can ping the TAP device, but not the drive (See attachment 8). Could someone explain how to properly configure all these settings? Thank you, GA

Post by levih on DocScripting ^{CODESYS Forge talk (Post)}
Hello I'm trying to use the DocScripting collection in Codesys. I've made it work on one PC(1) for the 3.5.16.4 version of the script collection. But when I try the same setup on another PC(2), I get an error message: Error loading Python DLL: D:\SCRIPTING\3.5.16.40\python27.dll (error code 14001) My setup on both PC's is thus: 1. Downloaded and installed Python 2. Copied the folder with the scripting collection to C: (because of admin rights) 3. Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4. I also can't seem to find any scripting collections on newer versions of Codesys? (e.g. 3.5.19.10) Thanks in advance!

Hi everyone. My question about: where I can learn (read or watch) an info about codesys workflow through the system IO libs? I want to know how to implement I/O drivers by my self. In the system libs I see many interfaces, methods etc... But there is no explanation about them, just names of methods and fields of the FBs. I know about this page: https://forge.codesys.com/drv/io-drivers/doc/Generic/ There is so BIG the device description file and not so clear explaining of the attributes and elements, also some elements or attributes missed at it all. Yes, there are code examples on this page, but, so shortly and, for example, code about Modbus drivers is absent. And even if I try to add the IoDrvFB with lib, I get and error, something like: "failed to load IoDrvFB driver". And what about the book of codesys that written by Gary Pratt? Is there information about system libs and drivers in this book more clearly? Thank you :)

I’ve added the EtherNetIP Adapter configured the network setting and added some modules to the pi but when I download the project it generates the following error: “There is no source code available for the object because it is in the compiled library ‘cip object, 4.5.1.0 (3s – smart software solution gmbh)’. Do you want to browse for the original library in order to display the source code?

I can’t find the source code anywhere or any information regarding this error. I’m using Codesys V3.5 SP19 Patch 3, the version of the Ethernet adapter is 4.5.1.0 and the version of the modules is 4.1.0.0. Any help on this will be greatly appreciated. Thanks

Post by yannickasselin on Connect to remote PLC via local pc and teamviewer ^{CODESYS Forge talk (Post)}
Yes it is possible. I did it a lot of times using TeamViewer VPN. Unfortunately, TeamViewer VPN only works on Windows. If the remote PLC is a Codesys runtime running on Windows, you should be able to login directly using TeamViewer VPN if it is installed on the PC/PLC. If it is not Windows based, you can still do it but you need to have a Windows based PC acting as a gateway in the middle. In this case you need to enable IP Forwarding on the Windows remote PC (the gateway) and you need to setup the gateway IP address on the PLC to be the address of the Windows PC. Then you need to add a route on your local PC to point to the gateway PC for Codesys communication. I know it may not be detailed enough but I did not want to make a whole tutorial on how to do it. Bottom line, it is possible. I do it all the time.

Post by fredsta on Unable to load dynamic modules (Download failed: Application=Application) ^{CODESYS Forge talk (Post)}
Hey there, I am currently trying to find a good solution for the communication between CODESYS Control on Raspberry Pi and "the rest of the world", i. e. the things apart from CODESYS on my linux. My first approach was to use the c-integration. So I created a lib, defined extern fbs, compiled the code on my Pi using the SDK and put the .so into my lib project. When I try to log into the Pi and load the program, I get the error message which you can see in the attached picture. "Die dynamischen Module der C-Integration konnten nicht auf das Laufzeitsystem geladen werden" is german and means roughly "the modules from the c-integration could not be loaded onto the runtime system." Is this normal? Am I doing something wrong? I will have a look at the unix domain socket thing next, as I am still in the process of finding the best solution for the communication.

Post by tim-roelant on Problem mit control runtime V3 und profinet ^{CODESYS Forge talk (Post)}
Ich habe einen brandneuen Beckhoff-Panel-PC mit einer Codesys Control Runtime V3 eingerichtet. Ich habe es zusammen mit 2 Profinet-Feldgeräten konfiguriert: einem 16in/16out IO-Modul von Turck und einem MTS-Linearencoder. Die Maschine funktioniert einwandfrei, bis plötzlich die Kommunikation abbricht und die Profinet-Teilnehmer nicht mehr erreichbar sind. Zu diesem Zeitpunkt kann ich das Gerät noch anpingen, aber der Profinet-Master findet sie nicht mehr: Wenn ich einen Scan durchführe, werden sie nicht gefunden. Wenn ich einen Kaltstart durchführe, wird der Profinet-Master wieder aktiv und die Geräte werden wieder gefunden. Im Protokoll erhalte ich den Ethercat-Paketempfangsfehler: sysethernet. Ich bin etwas verwirrt, es gibt kein Ethercat-Gerät im Gerätebaum. Ich habe den Sendetakt und das Untersetzungsverhältnis bereits auf höhere Werte eingestellt, jedoch ohne Ergebnis. Kann Codesys so konfiguriert werden, dass die Kommunikation ohne Kalt-Reset wiederhergestellt wird? Das ist sehr ärgerlich und verursacht viele Produktionsausfälle. Grüße Tim

With IFM sensors, I used their pre-built function blocks, but with this third-party device, i need to write my own function block. Thankfully, IFM provides a generic sensor-fb so I can write my own FB with "extends" and "super". So far, so good. I found the IODD and some other documentation and I thought I get how it works, but somehow can't really get it to work at all. From my understanding, i need to write data into the PDO-Array. But i get confused with the indices and subindices of IO-Link. I'll append the IODD and some screenshots of my project. There is an AOI for LogicXDesigner, but I can't use that in Codesys. I hope someone has integrated a IOL-device in Codesys before and can help me with this. Cheers leafy

An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Hello everyone, I have a working SPI connection (with transferExt) between a Raspberry master with Codesys and an ESP32 slave. I would also like to use a few GPIO pins. Is there a problem with using SPI AND GPIOs? Environment: Raspberry Pi 4+ with Raspian from Oct 23 Codesys V3.4 SP19 Patch 5 with Runtime Version 4.10.0.0 Device: GPIOs B+/Pi2 My problem: The status is displayed as “GPIOs : not running”. And also during mapping the message “The bus is not running. The values shown are perhaps not actual”. However, the variable changes that I make in my program are displayed under “Current Value”. In the Logic Analyzer, the pin toggles during transmission with small intervals of +-4us (seems to be a cyclical disorder, but I don't know where exactly it could be coming from). This applies to pins that I actually use (output) but also to the other GPIOs (not used). With GPIO 4, the line remains permanently high. Attached is a screenshot from the Logic Analyzer. Channel 1,3,5 were GPIO pin 26, 22, 17 Would be very grateful for help. Best regards
