Post by pouyavakili on Execute Codesys Tests with python ^{CODESYS Forge talk (Post)}
Thank you for your input! What I'm ultimately trying to achieve is automated test execution as part of a CI/CD pipeline (e.g. in GitLab or Azure DevOps). For this, I need to: Open a CODESYS project via script Build the project Run the Test Manager tests from a .TestRepository.xml Collect test results (e.g., pass/fail + a report) Exit with a proper return code (for pipeline success/failure) To integrate this into automation, I’m using the CODESYS scripting engine via Python (headless), but the issue is that the get_testmanager() function isn't available on the project object — even though Test Manager is installed, licensed, and works interactively in the IDE. Are you suggesting that I should: Use the Test Manager GUI to script the logic with its internal scripting language? Or is there a way to launch the Test Manager in headless/scripted mode, while still being able to control things via Python? If there's a supported way to automate tests with the Test Manager using scripting, especially from pipelines or headless environments, I’d really appreciate any pointers or example workflows. Thanks again!

Post by leandroct on Creating Boot Application not working ^{CODESYS Forge talk (Post)}
I have a Control Win V3.5 SP20 (64-bit) application, and until now, I open the program (with a password) and download it. However, I need to give the client the option to install the program on the Controller, without them having to open it and access the code. So, I followed these steps: 1 – In the Online => Create Boot Application menu, I saved the generated files in a directory: Application.app Application.crc PlcLogic\visu\ directory with several files 2 – In the SysTray, I ran the PLC, and it created a directory. In the root of this directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E84889DB), I pasted Application.app and Application.crc. Since it created a \visu directory, I pasted the PlcLogic\visu\ files generated in Create Boot Application into it. 3 - In the general Codesys directory (C:\ProgramData\CODESYS\CODESYSControlWinV3x64), I edited CodesysControl.cfg, adding: [CmpLog] Application.1=Application 4 - When running the PLC, nothing happens and the TargetVisu screen does not open. What I'm doing wrong?

Post by axilleas on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
dear all I am working on a very generic gantry system (virtual drives + win v3 control) reading gcode from external file. In order to stop the interpolator function from running when gaps are detected, SMC_controlAxisByPos FB has the bStopIpo output which according to the manual is connected to the Interpolator's bEmergencyStop. Lets assume that the axis are parked in position X1000 Y1000 and the initial G code movement is G00 X500 Y500. The normal behavior is to travel from the actual x1000 y1000 to G00 X500 Y500. The SMC_Interpolator always gets the X0 Y0 as the initial position, meaning that the bStopIpo is active until the axis are in X0 Y0 and the release the interpolator to set the new positions to X500 Y500. Is there a suggested method to solve this behavior? bonus question: I get a lot of bStopIpo during standard interpolation movements (not gaps). While working with virtual axis this is not a problem but when real axis are installed this will be an issue. What exactly triggers the bStopIpo output? Slow axis accelerations compare to Gcode defaults? Kind Regards

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 acc00 on Main Task cycle too long leading to PLC Fail ^{CODESYS Forge talk (Post)}
I have 2 Wago PFC200 PLC, running with Runtime SP19 Patch 5, with the Redundant application. The PLC communicates as Modbus Master with at this moment 15 Modbus Slaves -later there will be 28 in total- (Drives, Power management units,...). These devices are connected in 2 rings (1 ring of Drives, 1 ring of Power Management units), with 2 Managed Moxa Switches being part of the ring. Each PLC is connected to one of these switches. The issue I'm encountering is that the Cycle time of the Active PLC goes very high when I'm closing the Drive ring (simulating an issue on one Cabinet supply, resulting in that one Drive shut down, which can happen on field quite often). As a result of this long cycle, the PLC fails and goes to Exception, and the Passive PLC does not take control of the system. A normal cycle is around 30ms for the Main task, and a few ms for the Ethercat task. When I monitor with Profiler, I see that in this Maximum Cycle, the main Task is only taking 13ms, so I'm not sure where the PLC is hanging for so long. Is the remaining cycle time the Redundant management/sync or something else? Thank you in advance.

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?

Post by leafy on Use third party actuator with IO-Link Master (IFM) ^{CODESYS Forge talk (Post)}
Hey there! I am currently doing a little automation project for uni. I am trying to integrate a control-valve-system (Buerkert AirLINE Field) in my IO-Link environment. 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

The code is compiled, but the position has not been changed. Any guidance or suggestions for revising this code would be incredibly valuable. Your insights could be the key to solving this issue.

Hallo, Ich scheine den Grund gefunden zu haben, das Kabel mit dem RJ45 Stecker ist für RS232 verdrahtet (am anderen Ende des Kabels ist ein 9-poliger SUB-D Stecker, nicht wie von mir im Eingangspost behauptet ein USB Stecker). In der Anleitung des Treibers ist immer nur von RS 485 die Rede. Alerdings habe ich es gestern abend noch geschafft eine funktionierende Version der setup-software herunterzuladen, und die verbindet sich offenbar über RS232. Daraufhin habe ich mir in der Anleitung des Treibers das Pinout der RJ45 Buchse nochmal angesehen, und die hat Kontakte für RS232 und für RS485. (Die liegen jeweils ganz am Rand, so ist mir das vorher nicht aufgefallen). Ich muss also als Nächstes ein richtig verdrahtetes Kabel auftreiben, und dann sehen ob das mit dem Adapter den ich habe funktioniert. An einen Abschlusswiderstand habe ich auch schon gedacht, nur weiss ich nicht wo ich den an einem RJ45 Stecker / Buchse - Paar anbringen soll... Ich bitte um Entschuldigung für die Verwirrung, ich mache das alles zum ersten Mal und es ist ganz schön viel auf einmal für mich. Nochmal vielen Dank für die Unterstützung!

Post by mil581 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
Hello everyone! I'm facing a weird issue with CODESYS Control Win V3 x64 on a fresh Windows install. The situation is as follows: CODESYS Modbus TCP Server (Slave) is running and I can see live values in the mapping display of Modbus settings: GVL (e.g., 32, 42, 50). Port 502 is LISTENING according to netstat. When connecting via Modbus Poll or Node-RED, the connection status changes to ESTABLISHED and everything reports as fine. The Problem: Despite the successful connection, all holding registers return 0 no matter what. It's like the OS accepts the TCP handshake, the request counter goes up but the data payload never reaches Modbus Client (in this case Node-RED or Modbus Poll). Quick Stats: Firewall: Completely OFF. Unit ID: Verified & Matching. IP: Tried 127.0.0.1 and 192.168.0.1. Interface: Correctly bound in Ethernet Device settings. I already tried absolutely everything from changing IP address, subnet, port, deleting the project and starting new one and even nuking my old Windows install. Since I am near completion of my bachelor thesis only thing left for me to do is connect SoftPLC to NodeRED via Modbus but this issue is driving me crazy for weeks. I do not know what to do anymore.

Siehe folgendes Problem: CDS-81506 – Sicherheitslücke im Dateizugriffssystem des CODESYS Control SysFile-Systems. Es gibt zwei Lösungen: Ändern Sie den Speicherort der Datei (Sie müssen zu /PlcLogic/ wechseln). Wenn Sie die Datei nicht in PlcLogic speichern möchten, fügen Sie die folgende Zeile in der CODESYSControl.cfg unter [SysFile] hinzu: ForceIecFilePath=0 Hier die offizielle Versionsbeschreibung: [[COMPATIBILITY_INFORMATION]] Durch die Aktivierung von ForceIecFilePath ist der Dateizugriff von IEC nun auf die konfigurierten Pfade beschränkt (Dateisandbox)! [SysFile] ForceIecFilePath=1 (neuer Standardwert) Der Standardpfad ist das aktuelle Verzeichnis, der PlcLogic-Unterordner oder ein konfigurierter Pfad. Jeder Dateizugriff außerhalb dieses Pfades wird über PlaceholderFilePath konfiguriert, beispielsweise der Zugriff auf temporäre Dateien oder Wechseldatenträger: [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ PlaceholderFilePath.2=/media/usb, $USB$ PlaceholderFilePath.2.Volatile=1 Weitere Informationen finden Sie in unserem Tutorial „Dateipfade & Platzhalter“. Um das alte Verhalten wiederherzustellen, kann ForceIecFilePath wie folgt konfiguriert werden: [SysFile] ForceIecFilePath=0 Wir empfehlen jedoch dringend, diese Einstellung auf dem neuen Standardwert zu belassen!

Hi there I am running Codesys ControlWinV3x64 (Patch 4) on my laptop for demonstration purposes but I am unable to get connection to the EtherCAT master and slave device. This is the process that I have followed: * Installed NPCap. * Added the xml file for the SMC slave device to the Device Repository. * Activated Control Win SysTray x64 and selected Start PLC. * Scanned the network for the local device (my laptop). * Added an EtherCAT master to the project and scanned the EtherCAT master for the Network and then selected the correct network. * Selected "Scan for devices" to identify the connected I/O. * Add the SMC EtherCAT slave manually because I was unable to scan it in. * Selected "Scan for devices". I have followed the steps described above but I can't scan in the EtherCAT slave or connect to it. I thought this situation was unique to the EtherCAT slave but I have also tried the same for an EtherNet/IP slave using the Ethernet Adaptor and EtherNet/IP scanner and I am also unable to scan in the device or activate the EtherNet/IP network. Any assistance will be appreciated.

Yep sure, though now that i think of it, its a pi 4. My bad. The whole ordeal was necessary to use the VGA666 adapter. That needs the old graphical system and GPIO directly on the CPU. Edit: Putty on the virtual development machine connects fine. But i did change the login/pw. The account is still a sudo'er so that should be all right. Edit2: Sorry i get a "Comment rate limit exceeded" from the forum. Then i'll add it as edit here. So i have tried the stock raspberry pi image on a different pi5 (truly 5 this time). Packages updated. Standard password. Same symptoms, no runtime deployed and long hang time.

Edit 3 (Comment rate limit, otherwise it would be a new post) Now i have tried booting an older native Windows 10 machine (no virtualization), and it just works as expected. I have now a raspberry pi 4 and raspberry pi 5 with version 4.16.0.0 of the control application. Windows 10 native: build 19045 (same as virtualised Win 10), same .NET version, same CODESYS version. It seems that running CODESYS virtualized somehow messes with the deployment?

Post by alexgooi on Codesys KNX implementation ^{CODESYS Forge talk (Post)}
Dear forum, We are currently doing some research on the Codesys KNX implementation (https://store.codesys.com/en/codesys-knx-sl.html). We almost have it working but we are missing the last part. The setup: We have a Codesys virtual control container running on docker (4.17.0.0), the I/O is running over an Ethernet IP coupler (Weidmüller), and this is running fine. As far as I’m concerned this tells me that the ethernet device is working properly (the container has access to the outside world, including multicast). Underneath this ethernet adapter the KNX module is added (see picture). In the KNX device (Codesys) 2 input variables are added (see picture), and these are exported to ETS (ETS 5). In ETS A Codesys KNX device has been imported and the Codesys export was imported, afterwards the group addresses are attached to the variables (see picture). Afterwards this configuration is downloaded to the Codesys controller (Container) via ETS. ETS asks for the pressing of the programming button, when the virtual programming button is pressed the download starts and finishes without any errors. This tells me that ETS is communicating with the Codesys controller, and that the download process is ok (so far so good). Now the part where we are struggling with, somehow we need to convert the KNX TP to KNX IP. For this we have the following interface: Zenio KIPI SC (https://www.zennio.com/product/kipi-sc/) this is a KNX TP to IP interface. We have the following setup for this device (see picture) (an IP in the same subnet is used). We tried multiple combinations of IP addresses but the TP devices are simply not communicating to the Codesys container. Does anyone has any advice on what to try next. To make the question more explicit how can we link the TP bus to the Codesys device? Kind Regards Alex

Post by drbuzz on Communication Error (#0) for IFM controller ^{CODESYS Forge talk (Post)}
Hi Folks, Every time I use an IFM controller I always seem to run into a problem connecting to it. I get the Communications Error (#0). So I thought I would share some tips and tricks. Once the CANfox Cable (EC2112) cable driver is installed, you can use the yellow app in the sys tray to blink the lights on the cable. Confirm the cable works in the IFM maintenance software by connecting to the controller and reading the information on it. Make sure to download an OS into the controller (the light will go from a fast blink to solid green). In Codesys V2.3, the communication settings for the CR0401 is 250kBaud by default and Node ID 127. What got me, was I needed to reboot the computer after the cable driver install. Also if your application has canbus settings in it which are changed from default, after the controller is power cycled, the new Node ID and Baud will be in effect. I made a handy guide because too much time has been wasted on this. Programming IFM CR0401 Serial/Can Programming Cable • Connect IFM EC2112 CanFox programming cable with connector adapter. • Make sure cable is linked to VM (if using VM). • Install drivers for cable if not installed. o Download from IFM EC2112 site. https://www.ifm.com/ca/en/product/EC2112 • Once Installed, reboot computer. • In system tray, there should be a yellow icon that you can open and check on programming cable. Select the cable in the list and flash the lights to confirm it is working. Maintenance Software • Install IFM Maintenance Tool Software. o Download from IFM Site. https://www.ifm.com/ca/en/download/eco100_MaintenanceTool • Open IFM Maintenance software • Select Basic System • Select CAN cable • It will tell you if you don’t have a cable connected. • Use Wizard if needed. • Read Channel Parameter on the Settings page, or get Identity in the System Information > Identity. • Default Node is 127 on a new unit. Baud is 250kBaud (bits/sec) • Controller information should populate. • Controller green light should be blinking at 5hz (meaning OK but no OS, just bootloader). • Click Software > Load. • Open the OS file. Should match Codesys version selection (for CR0401 this is version 3). o Download OS file from IFM Website. https://www.ifm.com/ca/en/product/CR0401 o It is located at the top of the download under “software for CR0401”. o Select the file and load it… this will take a minute. • Once completed the unit should now have a solid green light o Solid green means the controller has an OS but no application is running. Codesys V2.3 Application • Codesys needs to be downloaded and installed from the IFM website as it has the IFM libraries and license to use the software. o Download from the IFM CR0401 page. o https://www.ifm.com/ca/en/product/CR0401 • Create new application with the correct IFM controller or Open Codesys application. • Keep in mind that the PLC Configuration on the Resources tab can be changed for the CAN communication interface… so changes to node and baud will take effect after the first download and reboot of the controller. • Go to “Online” in the top menu and change “Communication Parameters” o The Local dropdown shows the last configuration used. All other interfaces will show below it and need to be updated when changed or used. o Confirm Node ID is 127 for the first download.  The NodeID will change to whatever the program has after (in my case 125).  Node Send Offset should be default at 1536  Node Recv Offset should be default at 1408  Can bus Baudrate should be 250 kbaud.  Yes to Motorola Byte Order  Block Transfer should be false and note used (60 is default setting).  Can Card Driver should match the systray item which is Sie_USB. • If the system populated the other one, just update and relay the communication parameters. The software will usually bring up the available cable and driver. • Go to “Online” and Login to download. o Press Yes to Download Application. I hope this helps!

Hi dgrard, I had the same issue for a long time, but on a WAGO webvisu. Now I'm glad that I can share my solution. I don't know if you are trying to use the webvisu or the target visu, but this works on webvisu: Get "go2rtc" and set it up according to the documentation. I'm running the Windows binary. Here's my example of the go2rtc.yaml config file (contains working example streams): api: listen: ":1984" # default ":1984", HTTP API port ("" - disabled) origin: "*" # default "", allow CORS requests (only * supported) static_dir: "www" # default "", folder for static files (custom web interface) tls_listen: ":443" # default "", enable HTTPS server tls_cert: "./SSL/fullchain.pem" tls_key: "./SSL/privatekey.pem" streams: # Streams with multiple links will fall back on the next link.

Use the link as for your browser frame in the visualization. Depending on your device, you need to be able to access the file /etc/lighttpd/lighttpd.conf or /etc/lighttpd/webvisu.conf and change the contents similar to this one, otherwise you'll get CORS and CSP errors in the browser and you won't be able to view the stream on the webvisu: # Webvisu specific settings $SERVER["socket"] =~ port_webvisu_used_any { url.redirect += ( "^/webvisu/?$" => "/webvisu/webvisu.htm" ) $HTTP["url"] =~ "^/webvisu/?" { var.response_header_policy_webvisu = ( # CSP for WebVisu, allowing inline sources.

Post by gustavocsw on MQTT memory leak problem ^{CODESYS Forge talk (Post)}
Hello everyone, I'm using the IoT Library to implement the MQTT communication with my local broker server in order to publish and subscribe at specifics topics to share and consume information about my application. But, it seems that are occurring some memory leak problem in a "high" frequency (more than 10 Hz) subscribe process. I follow the same method as in IoT Lib exemples, and at first looks perfect but my PLC was rebooting frequently and when I check its memory usage that was increasing as fast as the subscribe massage was sent. I'm using a WEG PLC410 and a WEG PLC500, and this error occurred in both of them (including in CODESYS Control Win x64). The application sends to the system a message JSON with the float payload Ex. {"data" : 0.8500}, but this happens with a INT, or BOL as well. I use the follow code in my application to find the value: //FindFirstValueByKey VARs PROGRAM JSON_VELO VAR //------Setting the JSON Subscriber to Set the Relay Value jsonDataVelo : JSON.JSONData; jsonByteArrayReaderVelo : JSON.JSONByteArrayReader; xST1okVelo : BOOL; FindFirstValueByKeyVelo : JSON.FindFirstValueByKey; jsonElementVelo : JSON.JSONElement; xDoneReaderVelo : BOOL; xDoneFindVelo : BOOL; //STRING and WSTRING for Subscribe the massage sPayloadJsonVelo : STRING := 'opa'; psPayloadJsonVelo : POINTER TO BYTE := ADR(sPayloadJsonVelo); //wsPayloadJsonRelaySet : WSTRING := "opa"; wsPayloadJsonVelo : WSTRING := STRING_TO_WSTRING('opa'); pwsPayloadJsonVelo : POINTER TO WORD := ADR(wsPayloadJsonVelo); lrVelo : LREAL; xKeepAliveVelo : BOOL; xSetVelo : BOOL; RSSet : RS; LIMPAR : STRING; //Find the msg end sFindVelo : STRING := '}'; psFindVelo : POINTER TO STRING := ADR(sFindVelo); iLenVelo : INT; iSizeVelo : INT := 12; udiContMsg : UDINT; END_VAR // FindFirstValueByKey CODE // Relay Set configuration xSetVelo := MQTT_SUBSCRIBER.RSVelo.Q1; IF xSetVelo THEN xKeepAliveVelo := TRUE; END_IF IF xKeepAliveVelo THEN udiContMsg := udiContMsg + 1; iLenVelo := TO_INT(StrLenA(psPayloadJsonVelo)); iSizeVelo := iLenVelo - TO_INT(MQTT_SUBSCRIBER.udiPayloadSizeVelo); StrDeleteA(psPayloadJsonVelo,iSizeVelo,iLenVelo); wsPayloadJsonVelo := STRING_TO_WSTRING(sPayloadJsonVelo); pwsPayloadJsonVelo := ADR(wsPayloadJsonVelo); //MQTT.ConvertUTF8toUTF16(sourceStart:= ADR(sPayloadJsonVelo), targetStart:= ADR(wsPayloadJsonVelo), dwTargetBufferSize:= TAM, bStrictConversion:= 1); //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := TRUE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := xDoneReaderVelo, wsKey := "data", diStartIndex:= 0, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); IF xDoneFindVelo THEN lrVelo := jsonElementVelo.value.lrValue; //Reset jsonByteArrayReader jsonByteArrayReaderVelo ( xExecute := FALSE, pwData := pwsPayloadJsonVelo, jsonData := jsonDataVelo, xDone => xDoneReaderVelo ); FindFirstValueByKeyVelo( xExecute := FALSE, wsKey := "data", diStartIndex:= 1, jsonData := jsonDataVelo, jsonElement => jsonElementVelo, xDone => xDoneFindVelo ); xKeepAliveVelo := FALSE; GVL.xSetVeloRead := TRUE; END_IF END_IF And this to subscribe at the topic: //SUBSCRIBE VAR: //----------------- Subscribe Velocity ----------------------- MQTTSubscribeVelo : MQTT.MQTTSubscribe;//Variable MQTTSubscriber block -X - function-X wsTopicSubscribeVelo : WSTRING(1024) := "CORE/odometry/GET/data/simp"; // Topic to publish a message sSubscribeMassageVelo : STRING; udiPayloadSizeVelo : UDINT; xSDoneVelo : BOOL; xSErrorVelo : BOOL; xReceiveVelo : BOOL; eSTypeVelo : MQTT.MQTT_ERROR; eSMQTTErrorVelo : MQTT.MQTT_ERROR; RSVelo : RS; udiCont : UDINT; //SUBSCRIBE CODE: MQTTSubscribeVelo( xEnable:= MQTT_CLIENT.xConnection_Broker AND NOT xSErrorVelo AND NOT JSON_VELO.xKeepAliveVelo, pbPayload:= JSON_VELO.psPayloadJsonVelo, udiMaxPayloadSize:= SIZEOF(JSON_VELO.sPayloadJsonVelo), udiPayloadSize => udiPayloadSizeVelo, mqttClient:= MQTT_CLIENT.ClientMQTT, wsTopicFilter:=wsTopicSubscribeVelo, xDone => xSDoneVelo, xError=> xSErrorVelo, xReceived => xReceiveVelo, eMQTTError=> eSMQTTErrorVelo ); RSVelo(SET := xReceiveVelo, RESET1 := JSON_VELO.xKeepAliveVelo);

Post by gmau on Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired ^{CODESYS Forge talk (Post)}
Hello, I am writing to You with the problem of Profinet communication in my Codesys V2.5 SP21 project working on Codesys Control RTE V3 x64 device. I have implemented multiple Profinet devices in the network, the Profinet itself is configured properly, based on the hardware and software parameters of the industrial PC (Windows 10 IoT). My Profinet network contains such Profinet devices as a robot, IO-Link master with some devices on it, IO modules, safety, vision sensor (the configuration is attached to this topic). Once every few hours, sometimes more often, sometimes not even once a day, the error show up at one, two or a few random modules at the same time, every one is the same: "Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired". The communication is then lost with that module, but it is up instantly. It is not such a problem when it comes to regular IOs, but with safety or rotation table, it causes errors and machine stops. I have tried multiple solution based on any forum suggestions, manuals, etc., but it is still happening. Mabye when I turned on the Watchdog for this communication, it is happening less times, but still, I could not turning up the Watchdog parameters at the expense of cycle time of the process. The same is with Send Clock, Reduction and DHT. I have one of the ethernet port on the PC configured with CmpEt1000Drv driver. The card itself is Intel Ethernet Connection I219-LM. These devices are connected to one EKI-2728-NI-A Profinet switch (it was changed from the standard non Profinet one, but still nothing has changed). As I said ealier, I am attaching all the configurations for each device and the communication itself - if any of You had the same problems or have any ideas what could be the cause, I would be much gratefull for any help. For now I am out of ideas, if You have any additional question, please ask. Sincerely, PF

Post by rkohser on Scripted Git clone / checkout being blocked by "Project Environment" popup ^{CODESYS Forge talk (Post)}
Hi, I am trying to build a CI/CD pipeline around our codesys projects. The only entry point if the git url and branch, as we do not put our project file under source control, so we needed to find a way to git clone from the python scripting engine. This is currently how we do this : system.commands["Git", "Clone"].execute( "ProjectLocation=" + project_dir, "ProjectName=" + project_file_name, "RemoteUrl=" + project_git_remote_url, "GitProjectStoragePath=" + project_git_local_dir, ) system.commands["Git", "Checkout", "Branch"].execute( "PrimaryProjectHandle=0", "BranchName=origin/" + project_git_branch ) This works fine, except that, depending on the environment and the project, the "Project Environment" popup gets displayed to suggest for some updates, and waits for a user interaction, even with the "--noUI" flag injected as parameter. I investigated the VersionUpdateFlags, but the problem is that the git clone is an atomic operation that clones and directly opens the generated project without the possibility to inject any updateFlags argument (only used in the ScripProjects.open() function. I also tried to simulate some keyboard events acknowledge the window from script but I did not find the right location for the SendKeys statement, I think before the git clone call is too early and after is too late. So I am wondering if there would be some other way to do that. Is there some more proper scripting api for the git add on ? Is there a global configuration of the VersionUpdateFlags that would allow the popup to be disabled outside from any project context ? Is there some way to automatically acknowledge this kind of messages in a "--noUI" mode ? What do you suggest ? Thanks for your help, Roland Edit : I managed to solve my problem by following these steps in my pipeline : - create a template of a project and opt file preconfigured not to open the popup - open this project - initialize an empty git repo - add the remote, fetch and checkout the needed branch -> no popup is displayed, hourra Edit2 : The initial question was raised on a CODESYS V3.5 SP18 Patch 2 profile. Since CODESYS 3.5.19.30 a scripting API is available for Codesys Git that allows cloning a project with the support of VersionUpdateFlags https://content.helpme-codesys.com/en/CODESYS%20Git/_git_using_scripting.html
