Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Hello, I'm asking for help with installing the license server for Linux SL 4.18.0.0. When I try to install it, I get a message that the WIBUCodeMeter package is missing. I checked the package manager tab to see if the package is installed, and it is - Codemeter 8.40.7120.501. I've checked the CodeMeter Runtime on the target machine, and everything seems to be working fine. One thing caught my eye: the Device Architecture tab says "None" Please help me solve this problem.

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?

I have Already the same problem when i'm trying to write data more than 10 times in the same file. In fact, i send my data periodicaly to a file that i configured to have permission of W/R in my CodesysContol.cfg. When the Error occurs, i must reboot my machine to success. It means that the problem isn't realted to a limitation of size, but a problem in the function supposed to handle the file. totorovic : allow me to know if you've found a solution to your problem.

Post by imdatatas on SMC_ERROR.SMC_AXIS_NOT_READY_FOR_MOTION when using Drive Virtual ^{CODESYS Forge talk (Post)}
@ducng, Another possible situation could be that normally there are 3 inputs for MC_Power. In your above images, I can't see the "bDriveStart" input activated. As Mr. @gseidel mentioned, you need to make sure MC_Power.Status output should be TRUE. Issuing any movement command without activating the axis would naturally result in an error. For MC_Power; You can set the Enable and bDriveStart inputs to TRUE and try turning the axis activation on and off using only the bRegulatorOn input. Regards, Imdat

Post by gseidel on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
Hi kenth1973, MC_Phasing has been improved in recent versions. I would recommend to install the latest version of SoftMotion (4.20.1.0) and test whether the problem still exists, and if so, what the error identifier is. (Also check the PLC log in this case, it might contain additional information.) Setting the internal state of the FB is not recommended, it could lead to malfunction of the FB and unintended movements of the drive. Best regards, Georg

Just to clarify. Output for lamp will have two inputs: from plc IN (wall switch) and from visu button. Until now I had separate object for visu button and separate for visu lamp. Now I want it to be one object, bulb icone which will change color on lamp status and yet by touching it will change visu button state. Tried "Switch Image" object but there is no way to assign switch var.

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Didn't help. I'm just trying to understand why the errors occur. Are they from the poor driver or from the Linux network stack. That's why I wanted to know how the rxerros and lostframes are counted. Because in other places (like ethtool info) there are no any issues. And the Ethercat device works fine. And it also strange that on the second ethernet port with a different HW and driver Ethercat works better, but still time to time gets such errors.

Post by adamrobotic on llcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008 ^{CODESYS Forge talk (Post)}
Hi All, Recently I have been experiencing a issue in CodeSys SP16 Patch 3, with a exception which comes up after I have made several online changes. callcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008, after I experience this fault then I receive a error message for any subsequent online change "online change failed, no task gap within 10000ms". To recover either the controller needs a orgin reset, which will allow online edits thereafter until falling back into the loop. I am using a TURCK TX707 product which is controlling robot trajectory, We have hard coded the coordinate data rather than using persistence variables so hence the need to do online changes consistently. I have read on the forum other people have experienced similar issue with the online task gap, but I have no task which have same priority and also monitored the CPU usage and have not seen it go above 13%. Anyones help would be much appreciated, thankyou.

Post by ryandmg on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
Thanks So Much for the reply! Were using the Weidmuller UV66-ADV-10-CAP-W The HMI is pointed to the URL which is assigned through u-OS. Basically when you log into the controller's webserver via browser you can view the installed apps. One of which is the Codesys runtime. When you click on that it takes you to the visualization. That corresponding url is what the HMI is looking for. I apologize I don't have that on hand as I'm in the office right now. I don't think I tried connecting using the port you mentioned and https in lieu of the u_OS URL. I can certainly try. Out of the box the u-OS is set for HTTP. Since we're isolated I havent changed that yet. When this has happened while logged on via chrome on my laptop, simply refreshing brings the visualization right back. In the case of the HMI in kiosk mode, we power cycle the HMI to force a reconnect, log back in u-OS and the visualization is back.

Post by danwoodlock on RPI Zero w - Edge gateway cant install ^{CODESYS Forge talk (Post)}
Hello all, First post. I recently acquired an RPI zero W from amazon, and have been using it with Codesys v3.5 SP19 patch 2. I first got it working yesterday, and after installing the runtime on the Pi, I was prompted to install the edge gateway. Installation of the edge gateway failed because of unsupported architecture, undeterred I was able to connect to the pi and program as I wanted. The issue I've noticed is that if I do not load anything to the pi overnight, I can then no longer connect to the pi and download, although I can still ping it from my pc. I found that if I power cycle the PI, I am then able to connect again, and it works as normal. I did some googling and found instances where people recommended downloading the newest edge gateway, which brings me here. Wondering if there are any suggestions, or if this is a known issue. I actually tried installing all 3 versions of edge gateway for science, but all fail with the same message. Thanks -Dan

Post by toby on Ethercat Servo Setup ^{CODESYS Forge talk (Post)}
Hi Everyone, I have a simple project with a single servo, but its my first time using Codesys and motion, so I'm a little confused and lost, I've tried to read the tutorial online, but I'm not having much luck sorry. Can I please ask for some pointers. I have a ComfilePi HMI (Raspberry Pi) communicating to a Omron R88D-1SN08H-ECT amplifier. Please see the attached project file (which is better for sharing, the project file, or a archive?). This file was simply for testing the motion of the servo before anything else is tested with it. The project simply rotates the servo 1 rotation when called for, but the speed can vary based on user input. Nothing much fancy. As yet, I haven't had any servo movement, no errors on the amplifier display. How do I link the motion FBs to the physical drive? Thank you very much for any help you can offer. I'm sorry if I'm doing something very stupid or basic and getting it wrong. Have a good day. Toby

Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by moksan on Unconnected_Send Explicit message with Route Path ^{CODESYS Forge talk (Post)}
I have been trying out Unconnected_Send Explicit Message with route path.(The Unconnected_Send service shall use the Connection Manager object in each router to forward the message and to remember the return path. Vol 1.3 / 3-5.6.7) However, I could not see the correct path on Wireshark. I want to see the Unconnected_Send Message Service Code as 0x52 and also the last of the message should have the route path. I want to ask some questions about this topic. The IIoDrvEIPAcylicServices Interface has the IoDrvSendUnconnectedMessage Method. And there is a struct (EIP_SendUnconnectedMessage) for this service. But there is no information about how to implement to project, and if it is successful, does it send a message with 0x52 Unconnected_Send Service Code or not? If that is not a solution, how can I set the Unconnected_Send Explicit Message struct on Codesys? Also how can I send explicit message with route path?

Post by markusef3 on Verhalten bei zu kurz gesetzter Task-Zyklus-Zeit ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich habe eine Frage bezüglich dem Verhalten der Tasks. In der Hilfe und hier im Forum sowei im Internet konnte ich diesbezüglich leider nichts finden. Wie genau verhält sich Codesys wenn mehrere zyklische Task eingestellt sind und bei einem ab und zu die Abarbeitung des angehängten Programmes länger dauert als das Aufrufintervall eingestellt ist. D.H. der nächste Aufruf würde "theoretisch" erfolgen bevor alles im Program abgearbeitet ist. Z.B. Intervall ist 1ms, Abarbeitung dauert manchmel 1,1ms oder länger. (Watchdog ist zwar eingeschaltet, aber größer gewählt als das Zyklische Intervall zum Aufruf. Watchdog soll jetzt auch nicht das Thema sein). Was passiert in so einem Fall? - Wird das Programm zuerst zu Ende abgearbeitet und dann der nächste Aufruf gestartet? - Wird das Programm "mittendrin" unterbrochen und dann neu gestartet? - wie genau muss ich mir das vorstellen wenn dem so ist? - ...... - ...... Ich konnte überall nur Anleitungen finden wie die Tasks zu konfigurieren sind, jedoch nichts dazu was im oben genannten Fall genau passieren wird. Gruss Markus

Post by martinlithlith on Mux I2C ^{CODESYS Forge talk (Post)}
Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

Post by mm-sceg on Runtime geht sporadisch in Störung -> RaspiPi4 reagiert nicht mehr ^{CODESYS Forge talk (Post)}
Guten Tag, ich hab seit längerem das Problem, dass mein Raspberry Pi4 durch die PLC in Störung geht. Auf dem Raspi läuft eine einfache Software mit OPC UA server, InfluxDB und ein NodeRed-Server. (Und MQTT-Server) Daten werden von der PLC über OPC-UA an NodeRed übergeben. Es kann sein, dass der Raspi 2 Wochen läuft, dann geht die PLC in Stopp. Manchmal nur 2-3 Tage. Ein Neustart über Spannung aus & wieder an schafft Abhilfe. NodeRed wirft extrem viele Fehlermeldungen in kurzer Zeit. Wenn die PLC in Störung ist, kann man sich nicht mal mehr über SSH beim Raspi einloggen. Der Raspi ist aktiv gekühlt und im Normalbetrieb nicht überlastet. Ich hab einige logfiles mit vielen Einträgen die mir nichts sagen, eventuell hat hier jemand eine Idee wie ich dem Problem Herr werden kann :) Der letzte Datenbankeintrag von der SPS war am 11.11.2023 um 5:55:50 Uhr. D.h. danach muss die SPS gestorben sein. Siehe Raspi-Log im Anhang. Das LogFile von Codesys startet leider erst um 11 Uhr, weshalb weiß ich leider nicht. Vielen Dank schonmal

Post by timvh on VisuElems.CurrentUserGroupId is not stable ^{CODESYS Forge talk (Post)}
I'm not sure what you are trying to do, but getting the CurrentUserGroupID like this will not work, because there could be multiple Visualization Clients and each can have a different user that is logged in. Also when you go online with CODESYS and open an Visualization, this is counted as a client. Probably this is the reason you see it changing. What you can to is "iterate" over all clients and then see which user is logged in on which visualization Client. For this you need to add the Visu Utils library to the project and call the FbIterateClients. See https://content.helpme-codesys.com/en/libs/Visu%20Utils/4.4.0.0/VisuUtils/VisuActionUtilities/Function-Blocks/FbIterateClients.html fbClientIteration( xExecute := x_Execute, itfClientFilter := VU.Globals.AllClients, itfIterationCallback := fbIterator, xDone => x_Done, xBusy => x_Busy, xError => x_Error, eError => e_Error); The fbIterator, in the example above, should be an instance of an FB which you have created yourself and this must implement VU.IVisualizationClientIteration. For example: FUNCTION_BLOCK FB_ITERATOR IMPLEMENTS VU.IVisualizationClientIteration Then automatically the corresponding methods will be called. In the HandleClient Method, you will get an interface to the client(s) and then you can get the current user through this interface: itfClient.UserGroupId You can also get the UserName: itfClient.UserName

Post by nizrahel on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hi all! I'm working on an home project using a Raspberry Pi 3 device with Codesys for Raspberry Pi 64 SL runtime. I would like to create the HMI interface with Siemens WinCC Unified (or Advanced) configuring the Raspberry as OPC UA server. I tryed everything, but I didn't find the way to let the OPC UA connection works using UaExpert. I tryed to use anonymous connection, authenticated connection and the ip address instead of the server name in the path connection. There is no way to connect to the OPC UA server and I was asking myself if this feature is really supported for the runtime version used. Another strange thing I noted, is that is not possible to quickly create an OPC UA certificate in the Security Screen, as show in any tutorials. I have correctly created the Symbol Configuration enabling the OPC UA feature. I attach to this topic some printscreen of the actual configuration (sorry for the italian language interface, but I didn't find the way to switch to english). Thank you very much in advance for your support and advices!

Post by ofey on Testing of Codesys program ^{CODESYS Forge talk (Post)}
Hi! I thought to hear what you guys think is the best way to test the program in my scenario. I have some PLC programs that have been made and deployed on different PLC's. The program has added the specific devices and IO that is applicable. I have made a test environment for everything outside of the PLC, ie. the same SCADA system that is talking to the PLC, and a program running locally is simulating the plant (level regulation of different tanks). Pr. now I have had to manually change the variables that are reading/writing values from the IO so they read/write via OPC instead. I also have to change the device tree from the specific PLC rack, to the soft PLC. So I kind of end up with two different programs that I have to maintain. I was just wondering if you believe there is an easier way to do this. So I can have the exactly same program and kind of switch between the soft mode, and the "real" mode.

After returning to version 1.5.3.0, the problems disappeared. Probably the version number of this library is responsible for supporting the appropriate Firmware Revision. Can anyone confirm or deny my suspicions?

Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.

I am setting the web browser URL as: 'http://127.0.0.1:8080/sample.pdf' but I get 'refused connection'. I got a similar error trying to open https sites and I discovered that I can only open http websites. Opening 'http://de.wikipedia.org' everything works fine. I also tried to check using code whether the sample.pdf is present in the directory. Unfortunately, when I try to read directories of 'PlcLogic' I get file FILE_OPERATION_DENIED (I am using File.DirList). I would like to be able to open PDF files in web browser. Possibly to move new PDF files in the folder as my customer wants to display different pdf manuals on the hmi. Here you find some screenshots and my .project. I am using Codesys 3.5.19.70.
