Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
Hello, I have a new project and I need to connect to a TCP socket using the URL instead of an explicit IP address, myendpoint@mydomain.com Which library is best suited for this? This is for a new enterprise project, the endpoint is a server in a datacenter running some real time application. We have big IP, it will automatically reassign the IP address to the backup server if a crash occurs so an explicit IP won't work for me. I've done this in RS logix, working now to migrate that code over to codesys. Thanks in advance!

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

Post by rafael on Wbm/runtime and visualization login ^{CODESYS Forge talk (Post)}
Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks

Post by adaml on ScriptEngine - execute "Export -> Bootproject and firmware (SD Card)" from python ^{CODESYS Forge talk (Post)}
Hi everybody, recently I was checking how many time consuming manual tasks I can perform with python scripts through ScriptEngine. I have in the project many devices and currently I export bootprojects for them by right clicking on Application, then go Export -> Bootproject and firmware (SD Card) and then point folder where files should be exported. It's fine if project has few devices, but I have some of them with over 30 devices and manual clicking like that is very time consuming. How can I do it with python script? So far I found "create_boot_application" method from Application object (taken by projects.primary.find('Application', True)) but it only generates .app and .crc file instead of full structure to store on SD card (FIRMWARE, USERDATA, SDCARD.INI, Version, Version.txt.sig). Should I use some method to control user interface? Best regards, Adam

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!

Post by abrarsk on SysCom Library Usage ^{CODESYS Forge talk (Post)}
Hello all, I am facing issues with using SysCom library. With SysCom23 library things were simple but since we are migrating to 64bit systems, I am writing a Porting program. With SysCom23, opening the comport was as simple as providing the ComPort no. which returns the Handle as a DWORD. dwHandle:=SysComOpen(Port); But the new library is a bit different. It is asking for 2 input parameters to open the Com Port - Port Number and POINTER to RTS_IEC_RESULT IF hCom = 0 THEN hCom := SysComOpen(ComSettings.sPort, ADR(pResult)); How should I use the RTS_IEC_Result? I can find RTS_IEC-REUSLT under SysType2Interfaces of SysCom library. Also, can someone give me a general understanding of this RTS_IEC_REULT and RTS_IEC_HANDLE, etc.?

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 installwhat on IDialogOpenedListener ^{CODESYS Forge talk (Post)}
Why do you develop things like this? The workflow should be highly dependent on autocomplete, then if that's not super obvious browse to definition and everything is made clear possibly with the checking of a few types. The nature of how things are done makes me think these libraries aren't developed for general use and are actually internal or for partners. The example projects include objects that don't appear in autocomplete and then lead nowhere obvious when browsing. Do you consider developer workflow when creating these libraries? Are some libraries really for public use such as Visu Utils and others not? If so which? It's really hard to tell.

Post by lukebouchard on NVL generating ADwin packets instead of UDP? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5 SP11 32bit to program a pair of IFM CR711S controllers. They each have an NVL sender and are set up to receive each others messages. One is transmitting properly but not receiving, the other is receiving the first's messages just fine. When I look at the traffic in wireshark, I can see the one transmitting properly as UDP packets on the subnet and port I had specified. The Second is transmitting on the right subnet and port, but is sending 'ADwin Config' packets. Has anyone run into anything simmilar? From some reading on ADwin from google, nothing is enlightening. Both are set up in the same way, have their own ports and List Identifiers. I have deleted the NVL files and regenerated them, cycled power, and even deleted and remade the NVL's so many times.

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hi, I am looking for exactly the same thing. I would think that using a layer 2/3 managed switch should work but I am not convinced. I would like to test it in order to see if it would be possible to run many Codesys Docker instances on a server and run only 1 ethernet cable from the server to a managed switch closer to the machines beeing controlled instead of having to run multiple long ethernet cables. I was going to buy a managed switch in order to test it but I want to first make sure it is possible and I want to figure out exactly what kind of switch I would need. Is this even possible? I think this is a feature that would be very useful paired with "Codesys Virtual Control SL". Thank you

Post by dkugler on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
you can give this code snippet a try. It's extracted and simplyfied from my code: Install VisuElemBase lib if not installed yet. Execute in visu task: VAR pClientData : ARRAY [-1..100] OF POINTER TO VisuElemBase.VisuStructClientData; END_VAR VisuElemBase.g_ClientManager.BeginIteration(); pClientData := VisuElemBase.g_ClientManager.GetNextClient(); WHILE pClientData <> 0 DO pClientData[pClientData^.GlobalData.GlobalClientID] := pClientData; END_WHILE You have to make shure every no longer updated pointers in the array have to be deleted and no longer used by your code! Usage of this pointer access at your own risk :-) Works with SP16. From SP17 and newer there will be warnigs etc. using this solution as I remember. It will be great, if Codesys publishes a example or give a hint how to accesse this client values with the VisuUtil lib or other future-proof way!

Post by pierre on difference between stub file and source file in scriptengine ^{CODESYS Forge talk (Post)}
I included the stub files of scriptengine (codesys python api) in a directory scriptengine of a project. I tried to include librarymanager like that: from scriptengine import librarymanager visual studio code detected an error. It said librarmanager could not be found. Indeed in the stub file, this was library_manager. But if I change it in my code, the plugin doesn t work anymore. I found an easy solution to this problem. I ve just changed the copied stub files.(library_manager -> librarymanager) But I think it would be better if you update it yourself in the future.

Post by davidbo on RPI can system operation like rm in a shell have an impact on a Task cycle time ^{CODESYS Forge talk (Post)}
I have noticed that a rm file1.txt command on a shell has an impact on the cycle time for a TASK writing to file2.txt. Seen in the Monitor fane of the Task configuration Furthermore if a TASK makes a system call like rm, its cycle time increases of course but it seems to have an invisible impact on other TASKs too. I have a TASK for handling communication over the CANbus (SPI) where it stops sending "Heartbeats" for many seconds when another TASK does a system rm. Why is that not seen on the Monitor fane? Is even codesyscontrol paused when system calls are made? The CPU load is about 30-40%

Post by timvh on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
If you are not using any specific Raspberry Pi functionality, then probably the "universal" Control Linux ARM SL is the approriate runtime to run on the Pi. For the license it doesn't matter which runtime version you choose, because this is not hardware based anymore, but application based. Best is to use the latest version of CODESYS. To determine which license you need, double click on your device, go to the tab License metrics.... Generate the code for your application and see which license you need based on the metrics of your application.

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.

Hello, I have experienced the same issue as described above but for the Modbus Serial configurator. Looking for a solution. In v3.5 SP19 Patch 7 the Modbus Serial Master Slave configurator has a "virtual" limit of 10 channels. In v3.5 SP18 Patch 5 this virtual limit does not exist. I can successfully copy back and forth from 18 to 19 with out any build error. However, this is not a good solution for our customers. What is even more confusing is that the IoDrvModbus library is the same version (4.3.0.0) for both SP18 and SP19. Please help in providing a fix to the virtual channel limit of 10 in SP19. Thanks,

Post by robinluckey on IDE window handling bugs, windows diasppear, multi monitor setups ^{CODESYS Forge talk (Post)}
Codesys Windows (Main window as well as pop-ups) often appear outside of the viewable are in Windows when using multiple Monitors. This is exacerbated (happens more very often), when working on a notebook with different Monitor setups at different locations (which kind of is standard nowadays). The windows (not even the main Window) can not be recovered using standard short cuts like WIN + Arrow keys, alt + tab etc. The only way we found to recover the windows is by changing the Monitor positions in thew Windows Display Settings and than changing them back EVERY TIME a pop us is displayed. This makes using Codesys close to unbearable. All my colleagues face the same problem and do not have this problem with any other IDE. Please help.

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.

Post by struccc on Problem Update new version Master ethercat ^{CODESYS Forge talk (Post)}
Hi, I had some issues as well migrating to the new version. What I have learnt: - Have to check all the libraries in the library manager, if they are the proper versions. - Some other parts of the application, maybe an old library referenced by another one can keep the old Ethercat libraries.... Use the "Placeholders" function on the library manager - See if there is a new version available of the slave "devices". Might just have to update them ... I had problems moving from 4.7 to with 4.8, especially with the 2nd adapter for redundancy - some devices failed to initialize properly.... So I have just downgraded those libraries now. P.

Post by ben1 on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
If I am understanding what you are saying, then yes that would be your problem. I would create an array of bools on the client side for the transfer and try that. Or if client can't be changed then use words on server and unpack. But I am not sure if you or I are mis interpreting but it sounds a bit jumbled. I don't know what you have control of, but, if you are turning on BITS in the server, you should write to BITS in the client with a Function 15. If you are writing to WORDS in the server, you should write to WORDS in the client with a Function 16.

I have a WAGO PLC, to which I am establishing a connection. Here I use the autodiscover to register the connected modules. Now, I have tested the in-/outputs of the different modules, to verify they are consistent with how they are physically connected to the PLC in regards to how CODESYS has numbered them. Will CODESYS always number the modules closest to the PLC itself lowest, and the one furthest away, the highest? I am rather new to the program, so I both hope my question makes sense, as well as not being completely obvious. Thanks!
