Post by adaffern on Runtime on Raspberry pi5 stops after 15 seconds ^{CODESYS Forge talk (Post)}
Hi Guys, I'm new to CODESYS on the pi and I'm struggling to get it working. My issue is that the runtime keeps stopping after approximately 15 seconds. I have installed the runtime package 4.11.0.0 on the pi, trying on both a 64 bit and 32 bit OS. Looking at old forums it all references the 4B and the fact they used 32 bit Debian bullseye (the last version of raspberry pi os) however the pi 5 doesn't offer this version when I try select it in the imager. Has anyone managed to get running using the pi 5? Any help would be greatly appreciated. Thanks, Adam

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
I have a version of codesys 3.5.16 on my local machine and a vm. The local machine has loads of codesys versions and libraries installed etc. I can open the FPosCR_Example_Project_SP16_patch1 project on my vm without any errors. On the local machine I get the error C0077: unknown type IoDrvEthercatLib.ETC_CO_SdoWrite. I can, on the local machine, declare a var of type IoDrvEthercatLib.ETC_CO_SdoWrite and include it in the code without adding an extra error. The problem only seems to affect the library. This is seems more an issue with my codesys set up rather than something with festo. I would like to know the possible causes. I understand most of the library manager features but it's not clear how to find the cause. Thanks

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge talk (Post)}
For anyone confused with the process visit this link (the bottom section about creating a .pfx file) https://content.helpme-codesys.com/en/LibDevSummary/certificate.html#import-of-client-certificates-with-private-key. I solved this problem by creating a .pfx file and importing it into the security store under 'Own Certificates'(must have SP18 or newer to import .pfx). I used a gitbash shell to enter the openssl command that created the .pfx file. Once you import the file, in your TLS context, set your 'sUseCaseName' to be the same as the name listed in the 'Information' column of your imported certificate. This did it for me

Hello, I'm trying to connect with a Wago TP600 HMI but without success. I'm using codysis 3.5 SP19 patch 7 (SP20 block all the time) and the official wago package is installed. However, when I scan and select my device, I get a message saying that the device doesn't match the project's device object with the possibility to update the device (as shown in the attached picture). however, after choosing to update i got a message that the device is not found. I've tried with a new empty project but the same results. do you have any ideas? Thanks.

Hi, I'm working with wago 750-8212 controller. I want to change the IP address of the Ethernet adapter from webvisu. I have read some other threads in this forum and I have tried the following: Added the following text to the config file CODESYSControl.cfg: [SysSocket] Adapter.0.Name="br1" Adapter.0.EnableSetIpAndMask=1 Used the below code : IF xUpdateEthernet THEN Ethernet.Enable := FALSE; Reconfig ( xExecute := TRUE, itfNode := Ethernet, eError => ErrorReconfig, xBusy => xBusy, xDone => xDone, xError => xErrorReconfigure); IF Reconfig.xDone THEN ErrorCode := Ethernet.UpdateConfiguredIPSettings(IpAddress := NewIp, gateway := newGateway, subnetmask := newSubnetmask); END_IF IF Reconfig.xDone OR Reconfig.xError THEN reconfig(xExecute := FALSE); END_IF Ethernet.Enable := TRUE; Reconfig(xExecute := TRUE, itfNode := Ethernet ); END_IF I could change the IP address but when i restart my Controller then the IP address resets to the original, Is there anything I have missed, what else can i try ? Thank you in advance.

Post by pazderai on CanOpen write issue ^{CODESYS Forge talk (Post)}
Thank you for an answer. Unfortunatelly, it doesn't work. The slave needs command byte as follows 0x22. It means expedited transfer where s-bit is not set, therefore data length is not specified. If I use segmented mode by CiA405.SDO_WRITE_DATA it produce command byte as follows 0x21 which is unfortunately supported by the slave and it returns with error 0x05040001 - SDO Abort Code -Client/server command specifier not valid or unknown. I can use CAN API low level to overcome this problem where it is possible to set 0x22 as a command byte, but than I can use user interface to set the communication probably, because I thing that machine expert uses library CiA405.SDO_WRITE for setting the slave. Or am I wrong?

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Post by askic on Generate FBs from source ^{CODESYS Forge talk (Post)}
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

Post by jnoyau on Visualisaion while in simulation ^{CODESYS Forge talk (Post)}
Hi all, Im new to Codesys 3.5, and am in the process fo making a visualisation i'd eventually export towards a Wago device. The issue I'm having currently is that when I compile and connect to the simulated program, my simulation won't launch. On the Visualisation tab, all I get is a text message (where previously there was my prepared visualisation) that says "The visualisation awaits a connection. Start the application" One thing to note: I work with Codesys 3.5 in french, so this is a rough translation. And a second: I'm not getting any errors nor warnings about the visualisation tab itself upon compiling Is there a step i'm missing after launching my simulation? Or would it be some really specific issue caused by the way I've set up my program? Thanks, J

Post by eguerra on Error in ScriptingEngine Docs - create_pou() ^{CODESYS Forge talk (Post)}
In the ScriptingEngine documentation there seems to be an error (or missing information) in the ScriptIecLanguageObjectContainer part ( https://content.helpme-codesys.com/en/ScriptingEngine/ScriptIecLanguageObjectContainer.html#ScriptIecLanguageObjectContainer.ScriptIecLanguageObjectContainer ). The description of the function create_pou() doesn't specify the correct arguments requested, it only says create_pou(type: SpecialPouType) and a script using the documentation definition of the function will raise an error. I tried passing the function arguments similar to the ones specified for the create_dut() function and it seems to work fine: create_pou(name, PouType) , name : str UPDATE: The offline help has the correct definition IExtendedObject<IScriptObject> create_pou( string name, PouType type = PouType.FunctionBlock, Nullable<Guid> language = null, string return_type = null, string base_type = null, string interfaces = null )

Post by sangeetnenwani on Test Driver Availability in CODESYS 64-bit and Test Manager 5.1.0.0 ^{CODESYS Forge talk (Post)}
I’m operating with CODESYS in a 64-bit configuration and the Test Manager at version 5.1.0.0, where I’m attempting to use project scripts from an earlier version. These scripts call for certain test drivers that are not present in my installation. It’s unclear whether the absence is due to the 64-bit system, an update in the test drivers, or if I need to enable or install additional elements. For instance, the loadproject(Codesys.Base) command is missing, but loadproject(testmanager.project) is available. The FileIO command for CODESYS isn’t accessible, yet the testmanager’s driver for it exists, as does the execuptscript command.

Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap. Please, if applicable, update these instructions.

Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by damian177 on Problem with downloading OPC UA tags by Data Source Manager ^{CODESYS Forge talk (Post)}
Hi, In Codesys V3.5 SP20, using Data Source Manager I am trying to connect to the OPC UA server and receive tags from it. The connection is ok, but the Codesys have a problem with downloading Tags group. The window (downloadingTags.jpg in attachement) never stop. After waiting for a while, I disconnect the connection and only the Server group remains downloaded, with OPC UA server diagnostic data (and this is read in Codesys). Of course, I tried connected via another OPC UA client : UaExpert , and everything works as it should, all tags are downloaded (Uaexpert.jpg screen). Has anyone on the forum encountered the OPC UA client configuration in Codesys? Is it possible to manually request the appropriate tags from the OPC server for reading in Codesys?

I ordered a cheap managed switch and tested it as soon as I received the switch. It works great! I even went a bit further. As you can see in the screenshot, I created 2 Codesys containers. Each one having 2 fieldbuses. The first one has EtherCAT and EtherNet/IP and the second one has EtherCAT and Modbus/TCP. All going through the same ethernet port from the PC to the switch. The switch splits it up into 4 different networks. The hardest part was to figure out how to configure the switch. @eschwellinger, thank you very much.

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
If you have a Windows system (RTE), then why not run the CODESYS HMI as separate controller. This could easily be moved to another PC if required. In the HMI you could also still use the Symbolic Var access as part of the Data Source Manager, although maybe OPC is the preferred way to make it more future proof. Or what about the Remote Target Visu. Then you can reduce the load of the main controller, while still only having to create one application including Visualization. This is now also supported for Linux systems. See: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_target_visu_for_linux.html https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_execute_remote_target_visu.html

Hi Tim. Not quite correct. What i'd like, is when you place the FB in prog, i choose a block NTC10k, and name this RT401. What i'm trying to do, is to get the name RT401 automaticly into the FB, so i can put this into the string i pass in a struct. So in var in POU, i saw this a place i could do this, RT401: NTC10k(Tag:='RT401'), but i can't get this to work. I shurly must have had something like this in FB: FUNCTION_BLOCK NTC10k String TAG But it's here where I'm stuck...

Post by pernockham on Linking to IO during runtime with hot swap? ^{CODESYS Forge talk (Post)}
I have a project where a single PLC shall control multiple nodes (up to 10 units?) with IO connected through profinet. Ideally each node should be identical however with time I see situations were different setups/configurations will be used. Codesys PLC (GVLs) |Profinet | |--PNIO-node-1--| | | AIO, | | DIO, | | CNT etc. | |--PNIO-node-2--| | | AIO, | | DIO, | | CNT etc. Ideally I think of a configuration through yaml/xml-files (the assignment/linking of the profinet nodes towards GVL-variables in the PLC as well as scaling, channel configration etc.). Would be grateful if someone could suggest library/-ies that can handle the following: - Verify what IO is connected to a device/node. - Hot-swap/assign link for IO towards GVLs, either automatically or through a HMI.
