Post by sanacfu on looking for v2.3 libraries on v3.5.19 ^{CODESYS Forge talk (Post)}
Hi all, I'm new to Codesys and Wago but well versed in Rockwell. I've been tasked with upgrading old Wago 750-880 PLCs that run Codesys v2.3. All I was giving is the original PLC program in v2.3 and the currently running machine. I've spec out to what I believe is a suitable upgrade, the PFC100 2ndGen, 750-8111. As I'm rewriting this code on the Codesys I can't find the same library functions blocks for ethernet settings PLC functions. Currently I'm working on code to get/set the PLC ethernet IP address and HMI IP addresses from the HMI screen. One other function I'm looking for is a warm reset function to the PLC. When googling for this stuff I see a lot of code not in ladder logic. Are these functions now not available to implement in ladder logic? Where can I get more information on finding and implementing this functions? Do I have to buy a license from Codesys to use these functions? The PLC I ordered should be arriving in 2-3 weeks.

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Hello mates, I'm working with CODESYS V3.5 SP20 on a Raspberry Pi and I use "Raspberry Pi MC SL" as device on the project. I've installed the Control Standard L (multicore) license on a Wibu System usb-Dongle (cmStick/4.50) that already had another license from another vendor. I follow the online activation procedure from CODESYS documentation. Raspberry Pi has already CodeMeter installed for the other license. When I plugin the dongle on Raspberry and start the Runtime from Raspberry Pi Update in CODESYS I receive the message that I'm on Demo mode because the license is missing. I double checked that the license is activated in the dongle, through the WebAdmin of CodeMeter and the second license runs properly without any issue. I have already try to change the dongle from HID to MSD device and backward but the the Runtime cannot recognize the Dongle. I have also try to stop and start the Runtime through CODESYS without success. Is there anything else I can do to fix this issue?

Post by timvh on License problem gateway ^{CODESYS Forge talk (Post)}
What we are trying to explain is that, yes CODESYS creates the software, but Epis decides how they implement it on their hardware, which runtime version they use and they decide which functionality they support. So it is always a combination of the two. What CODESYS provides is a runtime with options for e.g. visualization or softmotion. Epis could add this softmotion license as default to their controller, but if they don't then CODESYS provides another option with a single license in a "Wibu CodeMeter" container. Eventhough the feature exists, Epis has to add this "CodeMeter" software on their controller to be able to access the licenses in the container. We don't know if they did this. Then finally it depends on what type of runtime is on this controller and which license Epis is using. So if they have an OEM license (not an application based license), then most likely you will need the Softmotion license (not a number of axis). See https://store.codesys.com/en/codesys-softmotion-sl-bundle.html. But to be sure if this is supported by the Epis controller, you must ask Epis.

Post by rabaggett on Reading Named Pipes in Linux Is there a better way? ^{CODESYS Forge talk (Post)}
I have a Python program that will handle things in my application such as VISA over IP and Telnet control of instruments. I want the main control and HMI in Codesys. My problem is communication between the two. I have looked at several ways to accomplish this, and settled on having the Python program create two named pipes, one to send information to Codesys, and one for Codesys to send information to Python. The information would be packetized with \n for end of packet.. Seems simple. I think the named pipes method should work, but file reading in Codesys using the CAA file library starts to get difficult when the file is never ending, as in this case. Before I spend too much time making something that may be fundamentally flawed I want to ask. Is there a better way? Is there a way to read the file 'one line at a time' which might solve my never ending file problem? Thanks!

Post by dogulas on OPC UA C# client connecting to OPC UA CODESYS server ^{CODESYS Forge talk (Post)}
Noob alert! I’m just getting my feet wet with CODESYS. I have a “Hello World” project in the CODESYS IDE. I’m using the Win SoftPLC on the same computer. I’ve added a Communication Manager under the Application node. Under that is “OPC UA Server -> IEC Symbol Publishing 01”. I also added “OPC_UA_Symbols -> Information Model”. I’m not sure I need the second thing. I was grasping at straws. I also set up several dummy symbols in the IEC Symbol Publishing 01 node. In my C# application, I am trying to get an instance of EndpointDescription from CoreClientUtils.SelectEndpoint(“opc.tcp://localhost:1217/Gateway-1”, useSecurity: false, 15000). I wasn’t sure about the “Gateway-1”. I found that in the CODESYS IDE under the project -> Communication Settings. When I execute the previous method call in C#, I get: “BadSecureChannelClosed”. I have no idea what that means. Any pointers to documentation are welcome.

Post by karel-bas on Loosing connection to emulation running on Linux ^{CODESYS Forge talk (Post)}
Hello, I am trying to emulate my code but for some reason my Codesys IDE keeps loosing connection to the emulator. I am constantly pinging virtual machine on which its running and its running fine, but codesys refuses to reconect to it, and is not able to rediscover it. Codesys 3.5 SP20 Patch 1 I have linux installed like image in attachment.(using version 4.12) Linux VM is set up to use up to 4 cores and 8gb of ram, with nothing else runing on it. I dont have a license so I am aware that the emulation shouldnt run for more then 120 minutes I am able to, login, get sysinfo, reboot etc from codesys IDE for certain period of time (5minutes) then my connection gets lost, sometimes I can login again, but sometimes i have to reboot the VM. Any suggestions what might be the issue ?

Post by elektron785 on Dongle von Linux-Modul (ARM64) nicht erkannt ^{CODESYS Forge talk (Post)}
Ich hatte noch einmal Zeit das mit der Lizenz zu probieren und habe dazu über den Codesys Installer das Virtual Control SL runtergeladen und ausprobiert, aber leider ohne Erfolg. Zunächst habe ich "Docker_codesyscontrol_virtuallinuxarm64_4.13.0.0_arm64.tar.gz" aufs Board geladen und das Image mit docker load geladen. Mit dem Befehl docker run --rm -dt --name codesys --network host -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ --device-cgroup-rule='c 13: rmw' --privileged 470a708f17a2 hab ich dies dann ausgeführt, aber das Problem, dass ich das Board im Netzwerk dann nicht finden konnte. Damit ich die Verbindung herstellen konnte, habe ich die Datei "DockerRuntimeStart.sh" so verändert, dass ich den Teil: -p 11740:11740/tcp \ -p 443:443/tcp \ -p 8080:8080/tcp \ -p 4840:4840/tcp \ gegen --net host \ ersetzt habe. Das Skript habe ich dann aufs Board geladen und bash DockerRuntimeStart.sh -i codesyscontrolvirtuallinuxarm64:4.13.0.0 -c codesys -H verdin-imx8mp- ausgeführt. Nun konnte ich in Codesys wieder eine Verbindung zu dem Board aufbauen, aber der Dongle wird leider immer noch nicht im Lizenz-Manager erkannt. Wie kann ich denn prüfen, dass auf den USB-Stick vom Container aus zugegriffen werden kann?

Post by mozed on Connection to device closed ^{CODESYS Forge talk (Post)}
Hello I am using an OpusA3 with version 3.5 SP17 Patch 3 as part of a project. I had no real problem before I encountered a problem that blocked me. The detection of the OpusA3 from Codesys is done correctly. The gateway is well configured and if I ping the gateway or the OpusA3 I receive the response correctly. The problem is that when I try to connect, the Opus screen freezes and a few moments later Codesys displays an error message ("connection to device closed"). I tried to change PC, to update the runtime, to change OpusA3 but the problem remains the same. I'm a little lost knowing that before it worked without problem. I went back to a previous version of the project (where it worked correctly) but the message still appears. Do you have any clues to solve the problem? Sincerely,

Hi, I am quite new to Codesys and I try to do a Profinet connection to an Siemens PLC (315-2DP) with CP343-1 Lean Modul. I already configured the Siemens PLC, exported the GSDML. Then I added a new project in Codesys, added following moduls: - Ethernet - PN_Controller - Imported Profinet Device via GSDML importer When I start the programm everything looks fine but I always get the message "Stopped Profinet" and no data is available This is only for a small test. Therefore I start to do that on a Windows 10 with Development System. Later I will try to realize this on Raspberry.

Post by tanman19 on How to Use Personal Access Tokens from GitHub with Codesys Git ^{CODESYS Forge talk (Post)}
I am trying to push changes to a GitHub repository. I set up the Git Remote with the correct URL and committed the change. When I push the change it asks for my GitHub credentials which I know are correct, when I type in my username and password it gives me an error: "The provided credentials seem incorrect." So I tried putting in my Person Access token and when I put that in with my username I get this error: "The server request failed and returned a HTTP error code 403: Forbidden". Does anyone know how to correctly use Personal Access Tokens from GitHub with Codesys Git? Does it have to do something with the remote url or my username? Any help or guidance would be appreciated.

Hello, I program a function for an Ethernet/IP controller. I made a structure with input and output corresponding with the map of my controller for the function block. My problem is that I don't know how to do the link between the controller and my PLC (CC 100 from Wago). The addresses declare in Codesys are illogic, The first addresses are 12 and 13 then 7 then 4. How to do corresponding the addresses of the controller and the input / output structure ? IP adress ? Does I must create the all variables of controller with the controller adresses to use with the function block ? Thanks for your help. (I hope I'm clear, I'm not english)

Hi guys I am trying to run on my laptop Codesys 3.5.19 Control Win x64 where I created a EtherCAT master. I have defined the controler, specified network adapter (my docking station) and everything worked as expected. Later I needed to test it on site (without docking station) so I changed the network adapter by EC master to my laptop network card. After that it shows "Network adapter opened" but no device can be found by scanning and in LOG is saying "SysEthernet: packet could not be sent, error code: -1". Same error with USB network card, but if I switch back to docking station, all is working again... Any idea what I'm doing wrong?

Hallo everyone, I am working on new PLC of Weidmueller that uses Codesys SP19. I made the upgrade at the Patch 4 coming from patch 0. Unce made the upgrade everything is working well in the progect except the web visu user menagent. In the new version, when I perfom the login, I cannot use the keyboard of the device; the window where to digit the user name and password opens, the buttons "OK" and "Cancel" work but the system doesn't allow to put input from the device keybord, the mouse behaves as it is an image. If I active the virtual keypad or numpad it works otherwise nothing. I am wondering if it is a bug of the new package or if I must set something else. Thanks in advance, Riccardo.

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

I have default arguments specified for function block methods but when calling a method, an error is produced requiring me to supply all the arguments despite there being default values. According to the online documentation, under section "Calling a Method" and subsection "argument passing" of the following link: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_method.html "Passing an argument for an input ... can be omitted ... for which a default or initial value was specified in the declaration..." I have found this to be the case for all Codesys IDEs I've used, 3.5.11, 3.5.16, 3.5.17, 3.5.19. Am I missing something?

Post by andrax on Save Recipe on Paspberry ^{CODESYS Forge talk (Post)}
Unfortunately not. The folder does not work. There are neither error messages nor any other indication that this may be due to missing rights. I have searched the entire forum and also tested the Codesys example. The simple recipe management generally does not work! The Raspi crashes with the extended recipe management from the example. I have now found another sample that works. https://forge.codesys.com/forge/talk/Engineering/thread/61c6a04b79/ Many thanks to mcodem. After some trial and error I have found out: xcreate must be called at least once at runtime. After that xload_write and xread_save work All other functions do not work. It is also possible to save to the /home/Documents folder. So it is not due to the rights. It would be nice if Codesys would check where the problem really lies.

The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

We have several old project written with 3.5.17 and 3.5.18 and also some older Until now when a customer ordered a product from us. We just installed (we have a tested image) and added a license Now the license policy has changed and we have to buy a License Control Basic S or M However it only works with CODESYS Development System Version 3.5.19.10 or higher Does that mean we have to upgrade all our old products? That is not a simple task as a previous post has explained with weird error messages from CODESYS V3.5. Next we have to do rigorous testing of our applications afterwards. It is very expensive

Hi, I am looking for a good way to update a decice remotely. The devices are distributed worldwide and have normally no connection to the internet. The CODESYS Automation Server can't help here. So I want to update the decices via USB stick. I have written my own code* to update the files that are created with ‘Create boot application’. But sometimes strange things happen: visu elements are present, but are not found the application is no longer registered and therefore no longer starts I have not yet found out why these errors occur. Has anyone had similar problems or found a better way? Is there perhaps a CODESYS library or something else? Many thanks! *the code deletes the directories on the device and copies the new directories from the USB stick while the system is running (goes without saying)
