Post by latassan on RaspberryPi 5 gateway problem ^{CODESYS Forge} ^talk ^(Post)
Hello, I'm trying to use a raspberryPi 5 as a PLC. I fixed its IP address, I can ping it. I've also installed the CODESYS Control for Raspberry Pi 64 SL runtime on it. So I've created a gateway (IP address of the Raspberry, TCP port 1217). I see the green dot next to this gateway. When I do a network scan, I can see my raspberry (see photo). When I try to connect to it, I have to define an administrator profile, which I do. On validation, I see a message: No device is responding to the scan request. I've checked that port 1217 is listening on the raspberry, I've uninstalled the runtime then installed it again, but I can't connect. Also, when I try to configure the user groups before connecting, I see that Offline mode is not supported by the device, even though I'm connected to it in the Deploy Control SL tab. When I try to refresh, I see: Gateway not configured properly. How can I connect to my Raspberry? Have I defined my gateway incorrectly?

Post by sbhaskarla on WebVisu File Transfer Error ^{CODESYS Forge} ^talk ^(Post)
I’m encountering an issue when downloading CSV files via the WebVisu button input config -> file-transfer option: • Custom directory: /plcdata/csv_logs/filename.csv o Error: Error 4 – Error during file transfer • Sandbox directory: /var/opt/codesys/PlcLogic/plcdata/csv_logs/filename.csv o Result: Download succeeds without error. Actions taken so far: 1. Added /plcdata/csv_logs to codesyscontrol.cfg (see attached). 2. Enabled file-transfer services in codesyscontrol_user.cfg (see attached). 3. Confirmed that the PLC writes CSV files correctly to /plcdata/csv_logs/. Despite these settings, WebVisu still returns Error when accessing the custom path 1. Using the placeholder file path '$$CSVLOGS$$/filename.csv' and it returns Error 6. 2. Using the literal path /plcdata/csv_logs/filename.csv and it returns Error 4 Could someone please help me determine what additional configuration or troubleshooting steps are required to serve files from /plcdata/csv_logs/? Please find screenshots attached for better understanding and I have also attached the config files

Post by alexgooi on Licensing info not available. ^{CODESYS Forge} ^talk ^(Post)
Sorry for the question, but I'm not completely getting the idea here, could you be more specific, maybe give an example? I'm now in a state where I don't have a softcontainer on my license server anymore (even after reinstalling from the Codesys-IDE). I tried reaching the webserver of Codemeter but when I do that I get redirected to http://"IP":22352 This is not reachable, afterwards I installed lynx on my Debian machine (command line only). From here I could reach the webserver and toggle the network server setting, but unfortunately this did not help. I also tried to changed the remote read setting to 1 (in the Server.ini file). But after a Codemeter reboot this is overwritten to 0. I have the feeling that it should be much easier to get a license to work, am I missing some checkbox somewhere? Is there a tutorial (or manual) that explains the licensing sequence step by step, because I'm pretty stuck.

Post by tortilla on J1939 connection between two devices ^{CODESYS Forge} ^talk ^(Post)
Hey, I'm pretty new to CoDeSys so I don't know a lot of things yet. I have to create a connection between two devices (CANbus - J1939 connection). The idea for now is to send a message from one to another (one operates on 3.5 SP11 the other one on 2.3) I watched a few videos, worked with the documentation and worked with chatGPT 4o and was able to build the attached file. This part is about the device on 3.5.11: I'm using the J1939LocalECUDiag, TransmitParameterGroup, TransmissionTrigger Function blocks to send the message but my TransmitPG.xBusy / .xDone never turns to True and therefore my message is not sent while TransmitPG.xExcecute is True. I added the two devices in the CANbus in the J1939Manager and addapted the options like I've seen in the documentation. Can anyone explain what's wrong with my code in this casse or give me advices how to properly create a connection between my two devices? Thanks in advance!

Post by caprez95 on Deleting the trend recording history ^{CODESYS Forge} ^talk ^(Post)
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by rk-gaw on Unhandled exception and refactoring error ^{CODESYS Forge} ^talk ^(Post)
Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.

Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge} ^talk ^(Post)
Some new test. Now I cannot connect from Automation server to my gateway in any way also from my office setup with my unit directly connected to my router by dhcp. I can use the IDE and the tool "Connect Edge Gateway" and successfully connect to my server/link to my Automation server account. However no PLC will respond from Automation server "Network scan". I guess the traffic should be initiated by the gateway towards automation server? Any tips on how I can diagnose my problem? Ports to be opened etc? Thing is that this has been working previously but not now (base system has been updated from debian 12 to debian 13, but I dont know at which point it has stopped working). Setup as before. A "Codesys Control for Linux SL" running on a debian 13 installation. Any help/tips appreciated! Per Update. Found the error. Had a wrong gateway-setting. Which meant the PLC could not reach internet. Checked by "ping google.com" from the PLC.

Post by kreisfilho on Stop raspberry from executing a plc program ^{CODESYS Forge} ^talk ^(Post)
Hi guys, Can someone inform where in a raspberry pi are stored the codesys programs? I´ve been training the use of a RPI as PLC, which works pretty well, however while both the RPI and PC (running codesys) remain connected to the same network. The question is: how to run the codesys program downloaded to the RPI as a stand alone device (disconnected from the PC)? Thanks! Kreis
