Post by aseitzinger on CODESYS Control for Linux SL on virtual machine? ^{CODESYS Forge talk (Post)}
Hello, there in different information available regarding the possibility to run CODESYS Control for Linux SL on a virtual machine. https://forge.codesys.com/trg/linux-sl/home/Home/ says CODESYS Control for Linux SL is a runtime system, which can run on any Debian based X86 PC, VM or Cloud container... https://store.codesys.com/media/n98_media_assets/files/2302000005/3/CODESYS%20Control%20for%20Linux%20SL_de.pdf says CODESYS Control for Linux SL can not be used on virtual hardware Currently I run the package mentioned on a virtualized debian machine running in PROXMOX Virtual Environment 7.4-17 and apart from huge jitter it runs without problems. The CODESYS key is passed as a USB defice to the VM. I wonder why there are different statements regarding the suitability in virtual machines and if the jitter would be reduced by installing CODESYS runtime on the host installing CDS runtime on the host and using a preemptive kernel (if available for the PROXMOX installation leaving CDS runtime where it is (on the virtualized debian machine) and install a preemptive kernel on the host and on the guest... Any advice is appreciated. Greets Arno

Post by anlebr on Codesys Communication Manger - Required information model version exists in the model repository but is not found ^{CODESYS Forge talk (Post)}
Hi I am trying use the Codesys Communication Manager to set up an Opc ua server with a custom information model. As a start I am using the Boiler model available on Opc foundations github page. I am testing with a Wago CC100 and using Codesys V3.5 SP19 Patch 6. I get the following error: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://opcfoundation.org/UA/Boiler/ with a minimal publication date from 15/12/2023 but the device has only a model from 15/09/2021 installed. Probably the information model from 15/09/2021 is missing in the information model repository. The error message does not make sense to me. Should it not be “Probably the information model from 15/12/2023 is missing in the information model repository”? Anyway, both versions are available in the repository. How can I solve this?

Post by william-blandon on RecipeManCommands.ReloadRecipes ^{CODESYS Forge talk (Post)}
Hi Dave. Thanks for your answer. I still struggling with this. I have done everything according with the Codesys help even I have looked in detail at the example. I have double checked the recipe manager configuration and the use of all the methods. There are two methods that do not work as expected. I'm using Codesys 3.5.19.20 and recipe management 4.4.0.0 .CreateRecipe just create a recipe in the recipe definition but do not create the file. This have a walk around just giving a .ReadAndSaveRecipe afterwards. .ReloadRecipes do nothing but do not generate any error as well. After calling it I call the .GetRecipeCount and the number is always 0. When I create a new recipe (using the function block methods) then the number changes. Looks like this method is looking to the wrong directory finding nothing. I don't know if there is a missing configuration in the CODESYSControl.cfg file. I'm thinking in a walk around for this but I need to create a strings array with the recipe names as retentive and making all the management when deleting and adding recipes. Have had some one the same problem?

Hello everyone. I've been struggling with the problem for a long time that I can't reset (restart) a trend (visual element). With the example I have now managed to control the trace recording via the CmpTraceMgr library. But how do I get this trace recording into a visual element? The code looks like this: // Configure trace IF xInit THEN // Create a trace packet PacketConfig.pszName := ADR('IECTraceConfiguration.Trace1'); // Name of trace PacketConfig.pszApplicationName := ADR('IECTraceConfiguration'); // Name of the application PacketConfig.pszIecTaskName := ADR('Task'); // Name of the task PacketConfig.pszComment := ADR('Demo packet'); PacketConfig.ulEveryNCycles := 1; PacketConfig.ulBufferEntries := 1000; PacketConfig.ulFlags := TRACE_PACKET_FLAGS.TRACE_PACKET_FLAGS_TIMESTAMP_MS AND TRACE_PACKET_FLAGS.TRACE_PACKET_FLAGS_AUTOSTART; IF (NOT fbTraceManager.CreatePacket(PacketConfig := PacketConfig, hPacket=>hPacket1)) THEN xError := TRUE; END_IF // Create a trace record RecordConfig.pszVariable := ADR('iSignal'); // This is the name of variable to record RecordConfig.tcClass := INT_TO_UDINT(TypeClass.TYPE_INT); // Type of the recording variable RecordConfig.ulSize := SIZEOF(iSignal); // Size of the recording variable pApp := AppFindApplicationByName('IECTraceConfiguration', 0); AppGetAreaOffsetByAddress(pApp, ADR(iSignal), ADR(RecordConfig.tvaAddress.taAddress.Area.usArea), ADR(RecordConfig.tvaAddress.taAddress.Area.ulOffset)); // Get and set area offsets RecordConfig.tvaAddress.ulAddressFlags := TRACE_VAR_ADDRESS_FLAGS_IEC OR TRACE_VAR_ADDRESS_FLAGS_AREA_OFFSET; RecordConfig.ulGraphColor := 16#FF00FF00; // green RecordConfig.ulGraphType := 1; // Line with points IF (NOT fbTraceManager.AddRecord(RecordConfig := RecordConfig, hPacket := hPacket1, hRecord => hRecord1)) THEN xError := TRUE; END_IF xInit := FALSE; END_IF // Starts the recording IF xStart THEN IF (NOT fbTraceManager.StartPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xStart := FALSE; END_IF // Stop the recording IF xStop THEN IF (NOT fbTraceManager.StopPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xStop := FALSE; END_IF // Reset the recording IF xReset THEN IF (NOT fbTraceManager.ResetPacket(hPacket := hPacket1)) THEN xError := TRUE; END_IF xReset := FALSE; END_IF

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 aris on Modbus write via FB failure ^{CODESYS Forge talk (Post)}
Hi all, I am using CoDeSys V3.5 and a soft controller Win V3x64. I am trying to read a modbus slave via Function Blocks and not via the channels of the hardware tree for the Slave. I created some requests of type ModbusRequest and I notice that I can read Input Registers and Coils but I can not write Holding Registers and Coils. I am using the library IoDrvModbusTCP 4.1.0.0. When i just use a single modbus request with FC06 (or FC16), there is no request sent to the slave and although the xExecute takes its true value from a pulse of 2 seconds duration, I take almost every 3 minutes an error "TCP_COMMUNICATION_ERROR - 16#A5 - TCP Port. error. Request was not sent". My code is ok because if i change the function code for reading registers, everything works fine. Did anyone have this issue in the past? Thank you in advance.

Post by valenting on License problem with Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I have a raspberry pi with a license installed, but Codesys stops after 2 hours, and when I start it manually I have the following message: pszInfo=!!!! no runtime license - running in demo mode(~2 hours) I tried using License Manager, and got the following message: Licensing info not available. There is no dongle attached to the device. I have this message frequently, and usually removing the content of /var/opt/codesys/.cmact_license makes it work. After doing it and restarting Codesys, I have an empty Softcontainer without my License. I tried using "Install license" using the .WibuCmRau file for the corresponding license and got the following message: Licensing info not available. The device does not support this service. I also tried using Additional Functions > Restore Licenses with the Ticket ID and got the following message: This device does not support automatic license backup. How can I reinstall the license to this Raspberry Pi?

Post by salvatorethomas on Port instantiation of serial interface in WAGO PLC using Modb_L05.lib in CoDeSys v2.3 ^{CODESYS Forge talk (Post)}
Hi — good description of the problem. A few suggestions / questions that might help narrow this down: Since your first serial port (COM2) works fine but the second (COM4 + MODBUS_EXT_MASTER) never opens, check whether the two ports are truly independent — some WAGO modules share internal resources, so COM4 might conflict with other functions or modules. Make sure that the physical wiring and module configuration for the second port (baud rate, flow control, RS-485 vs RS-422, etc.) exactly match what the library expects — a mismatch in flow control or wiring could prevent port opening even if the LED signals seem OK. Try using a plain SERIAL_INTERFACE on COM4 first (like you did for COM2) without Modbus logic — if that opens, you know the hardware + port config is fine, so the issue is more likely with modb_L05.lib. If the port opens but Modbus still fails, enable debug/logging (if available) to inspect whether the port opening fails or the subsequent Modbus negotiation fails. If you like — I can share a minimal example project I used with WAGO + COM4 + Modbus that worked; you could adapt that to test your setup. Wacky Flip

Post by madskaizer on Task Priority Documentation? ^{CODESYS Forge talk (Post)}
Hi All I was watching the Wago PFC300 webinar ( https://www.wago.com/global/lp-thank-you-onlineseminar-pfc-300 ), and the presenters comment about priority 1 being way above the Ethernet task priority, so that a priority 1 PLC program can actually loose SCADA connection, made me try to round up some hard evidence on Codesys Priorities. I find there is very little information on "correct" task priority configuration. There is a lot of different hardware manufacturers, using Codesys Runtime, that has different descriptions in their manuals on how to set up priority. https://doku.amk-motion.com/en/Subsystems/PDK_202975_A-Serie_en/Content/Projekt/AMKAMAC/PDK_202975_A4-A5_Produktbeschreibung/Funktionalitaet/PLC-Programming/PLC%20Tasks.htm?TocPath=PLC-Programming%7C_____7 https://product-help.schneider-electric.com/Machine%20Expert/V1.1/en/SoMProg/index.htm?#t=SoMProg%2FTask_Editor%2FTask_Editor-7.htm&rhsearch=priority&rhhlterm=priority&rhsyns=%20&SUBSTRSRCH=1 https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_f_task_configuration.html So my questions :) 1) If there is only 1 PLC_PRG task, does priority matter? 2) What is the priority of Ethernet / communication, if nothing is entered? 3) What is the priority of Codesys OPC UA server? 4) Some users here on forge mentions that Wago PLC programs should run as priority 11, but where does this recommendation origin from? 5) What are you recommendations for a relatively slow process, like building automation? It uses OPC UA for communication to SCADA, maybe some MODBUS-RTU and MODBUS-TCP, usually around 100 I/O, been running with everything in a single task at priority 1, 50-100ms cycle time. Some controllers have separate MODBUS tasks, but doesn't seem like a big difference. How would you recommend splitting up communication, IO fieldbus and programs into differently prioritized tasks? I know its a complex matter and all about my application, but I really miss there was just some kind of guidance in the documentations and with all new standard Codesys programs having priority 1 as default, makes it seem less important, than it really is.

Post by smartcoco on The text list provided outside the library is not available for visualization controls within the library. ^{CODESYS Forge talk (Post)}
I have a project called 'DemoProject' and a library called 'DemoLib'. Create a visual control named "DemoVisu" in the library, with a selection box of type "ComboBoxInteger" in the space. Now 'ComboBoxInteger' requires a 'Text list'. This "Text list" is provided when I call the "DemoVisu" control of the "DemoLib" library in "DemoProject". And this text list is in 'DemoProject'. I found that 'ComboBoxInteger' no longer works at this time. Other visual controls that use text lists also have this issue. I hope there is a good solution to this problem.

Post by grant32 on Codesys ARTI .XML file not creating but working. ^{CODESYS Forge talk (Post)}
Hello, I am working on a project with a Beijer Nexto Xpress. I have done this a few times with no issues but for some reason this time when creating a Symbol Configuration the ARTI .xml file is not being created in the Project Folder. However when manually putting the ARTI tags in the HMI program they are connected and work. So I am just not getting the file to import all the tags. I can do it manually which is fine but no matter where the project folder is saved this occurs. Anyone experienced this? Did not see another forum on it.

Post by dhumphries on install codesys runtime on linux ^{CODESYS Forge talk (Post)}
I'm running the 3.5.18.20 IDE, installed the control for linux SL package from the installer. Following the directions here: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_install_runtime_on_controller.html it says: Installing the runtime package with CODESYS on the Linux device Click Tools → Update CODESYS Control for <device> SL.</device> I don't have the update option in my tools menu. I've tried it without opening a project, as well as with a project open that uses the control for linux SL as a device. I have found the update device option by right clicking on the device in the device tree, but this only lets me change the device the project is using not load the runtime on the linux computer. Is there an updated instruction somewhere, or do I need to do some further preparation like install additional packages?

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I'm getting closer to the error. The combination of STRUCT and ARRAY probably causes the strange behavior. As soon as the ARRAY is followed by a variable, the problem arises. Examples: X: ARRAY[1..2] OF INT; // okay Y: ARRAY[1..2] OF STRUCT; // problem Z: STRUCT; Z.ArrayOfInt[1]; // okay Z.ArrayOfStruct[1].Variable // problem // *update - array of array also causes the error A: ARRAY[1..2] OF ARRAY[1..4] OF BOOL; // problem I can't be the only one who has this problem. Or? Maybe there is a solution. Anyone? Or is it a bug after all?

Post by appling on License status of Linux 64Bit runtime via CLI ^{CODESYS Forge talk (Post)}
Hi, I have a Linux 64Bit system with a Codesys application running on it. It stops after 2hours and a few minutes, which makes me think something is wrong with the installed license. (in my last timing it stopped after 2h4min, on the codesys website it is stated that runtimes without a license stop after 2h) I installed the license via a USB license dongle that I activated on my workstation with the Codesys IDE a while ago. Now the system is shipped at not accessible physically, only remotely via SSH. So is there a way to check the status of the License of the Codesys runtime when it is running on the system? Running the codesyscontrol script with "status" just tells me that it is running, but does not provide any license information. Best regards

It could be a problem with the cable pinout on either side: 9 pin D-SUB connector (male) - PC side Pin Potential: 1 n.c. 2 RxD 3 TxD 4 n.c. 5 n.c. 6 GND 7 n.c. 8 n.c. 9 n.c.

Post by wbj0t on Raspberry Pi CM4. CoDeSyS files corrupted after hard reset. ^{CODESYS Forge talk (Post)}
Hello everyone. Raspberry Pi CM4 after some 1 week of work was hard reset mannualy several times and after these hard resets User Management file was missed (when click login button, enter login/password, error: User Management File missed). Also programm can not open file via SysFile library, but this file exists and size of him is 0 bytes, but must be more any way (I keep some kind of archive via this lib). What happens, how files corrupted? Where do I need try to find this error of the codesys or system whole? In the log files of codesys nothing interesting about this happens. Thanks for reading Is this enough hold PlcLogic and SysFileMap.cfg as reserve copy in another place for restoring the programm? And how automate restoring actions if programm files corrupted?

Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!
