Post by patliby on Cannot Find "Automatically Generate POUs" Option ^{CODESYS Forge talk (Post)}
I would like to enable the feature to automatically generate POUs for Project/Library properties in some of my library/project files. The Codesys help pages indicate it should be on the bottom of the Project Information Summary tab, but mine has no such options (see screenshot). Is there somewhere I have to enable this overall feature or any other prerequisite I am missing? I am using Codesys 3.5.19.20 Reference https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_obj_project_information.html#UUID-9ddc3572-a024-5a49-c0c1-31677991a419_id_c95bfe46c6c18a67c0a8640e01715107_id_0a188ec6fa561b9fc0a8640e0019d8bf

Post by janp on IFM Controller Connection Issue ^{CODESYS Forge talk (Post)}
Hi everyone, I’m using an IFM ecomatBasic CR413S controller and having trouble connecting it to CODESYS 3.5. I have CODESYS SP18 installed, as recommended in the manual, and I’ve tried different patches. I’ve also installed all the packages provided on the IFM website for this controller. I can successfully connect to the ecomatBasic template, but I’m unable to connect when using the CR413S-specific template that includes all the inputs and outputs. Has anyone encountered this issue or knows a solution? Best regards, Jan

Post by ggis on Manage Gateways between different CODESYS IDE versions ^{CODESYS Forge talk (Post)}
Hi, I'd like to share the list of gateways between different versions (and sandboxes) of Codesys IDE. I refer to the list that is managed in Device > Communication Settings (as described in https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_edt_device_communication_settings.html ) Can I export/import that list? Or is there a file that I can copy from one installation to another one? Thank you GG

Post by eschwellinger on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
I would recommend to ask Moxa for a newer version of Debian. Debian 9 ("Stretch") has reached its end of life and is no longer receiving security updates from the official Debian Security Team as of June 30, 2022. This means any systems still running Debian 9 are vulnerable to security risks and should be upgraded to a newer, supported version of Debian like Debian 10 ("Buster") or Debian 11 ("Bullseye").

Post by arwie on Working on exporting/importing projects to PlainText. ^{CODESYS Forge talk (Post)}
To better track project changes in git I created a script that exports the project structure as text files. Textual POUs are stored as text, everything else as XML (with timestamps removed). The file structure is stored under path/to/your.project.txt Git merge will not work, but at least tracking changes is much easier. Script: https://github.com/arwie/controlOS_demo/blob/main/codesys/txtfy.py Example output: https://github.com/arwie/controlOS_demo/tree/main/codesys/controlOS_demo.project.txt

Post by ivan-g on MODBUS ^{CODESYS Forge talk (Post)}
Hi There, I took over a project from a colleague (in GTB) who left the company. When I took over his project, it wouldn't compile because some libraries were missing. I managed to recover quite a few libraries, but I can't find the library that contains the block functions shown in the image. Here are a few examples: Fb_RegMel_ISO Fb_DefModbus FbDecalConsSalSO Fb_Autor_FreeCool_CTA_C I'm a little stuck at the moment, so if you see a Facebook post that speaks to you, don't hesitate to get in touch! Thank you in advance for your help.

Post by timvh on I want to show the current recipe name in the visualization screen ^{CODESYS Forge talk (Post)}
Maybe the easiest solution for you is to add one STRING variable to your recipe and enter the name of the recipe in variable value. This is little bit double the work (naming the recipe and entering the value of the STRING variable), but in that case you always have the current value of the variable which you can read from the application and show in the visualization.

Post by nathant on Some visualization objects disappear when user is logged in? ^{CODESYS Forge talk (Post)}
I am deploying a webvisu on Codesys 3.5 SP 19.2 with legacy user management. I noticed that when a user logs in, some text and a rectangle I have (for aesthetics) both disappear. I made sure that none of the objects in question are linked to a state variable. Anyone know the cause/solution to this? Nothing crucial to the machine's function is lost, but it is a little annoying.

Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

Hi Edwin, Thanks for the message. My apologies I should have researched this more thoroughly before posting on here. I found a solution to my issue on this post: https://forge.codesys.com/forge/talk/Runtime/thread/6455efaa17/ I needed to run the 'CODESYS Installer' as an Admin, then install the RPi package v4.10.0 in to my package (v3.5 SP19 Patch 5). Thanks, hope you have a good day. Toby

Post by rpostwvu on Shared Memory Access Issues ^{CODESYS Forge talk (Post)}
I got the shared memory example. I'm pretty sure I'm successfully created a memory space, CreateResult returns 18. szName:='CodesysDataShare'; hShm := SysSharedMemoryCreate(szName, 0, ADR(uxiSize), ADR(CreateResult)); I'm trying to access this memory with a C# application, but I get "Unable to Find Specified File". I suspect that Codesys and/or Visual Studio code alters the name I choose? Being in Windows, I cant find a way to see the mapped memory list. ~~~ using (var mmfRead = MemoryMappedFile.OpenExisting("CodesysDataShare",MemoryMappedFileRights.ReadWrite)) ~~~

Post by ofey on two different OPC clients with different privileges ^{CODESYS Forge talk (Post)}
Hi! I have usually only connected one OPC client (our system) to an OPC server created in the codesys environment on a PLC. This OPC client has a lot of write privileges. A customer also want OPC access, but I want to restrict his access to only read certain values. Do you know if this is possible inside the single codesys runtime running on a controller?

Post by jinlee on Multiple WebVisu ^{CODESYS Forge talk (Post)}
Hi, thank you for replying. Basically, I have a main visu with frame selection. So, under some condition the frame will switch to a specific frame. It used to be controlled by variable using "Switch frame variable". However, I realise it will change all the HMI screen at one time. So I removed the variable, and still looking for a solution to do that. Do you have any idea?

Post by amy123 on CSV Utility CANNOT_OPEN_DIRECTORY ^{CODESYS Forge talk (Post)}
Hello, I tried using the CSV Utility SL Example from the CODESYS IIoT Libraries SL. No matter what path I try, I can not get the InitSave to work from CSVWRitersSTExample, line 2. It always gives the error 'CANNOT_OPEN_DIRECTORY'. I am running this on an Windows Azure VM, with Codesys Control Win V3 x64. I added a folder called 'temp' to my C: so that the default 'C:/temp' would work. However it gives CANNOT_OPEN_DIRECTORY. I tried updating to 'C:\temp' with the same result. Any help would be greatly appreciated!

Hello there, I have an eip adapter running (remotely) that is sending data back to eip scanner (running on codesys). I can send data from scanner (codesys) to the adapter but not getting the data back from the adapter. I have verified the incoming data on wireshark but I don't see this data in the codesys. I have tried local variable mapping and global variable mapping not variable values just stays at 0. Please guide.

Post by timvh on IFM CR711S Version Mismatch ^{CODESYS Forge talk (Post)}
You should ask IFM to provide you with the correct version of their controller packages. Then after you have installed this, you can select the correct version of the controller by right clicking on it in the device tree, update device, enable the option "Display all versions" and then select the version which matches your controller. Alternatively you can ask IFM to provide an update package which can update the runtime version on your controller to 3.2.0.0.

I also tried the option to "Perform static analysis automatically after compilation" # get Project values myProject = projects.primary # Creates an active application app = myProject.active_application # build Application and run static code analysis app.generate_code() Could you please offer any insights into why this might be occurring?

My problem now is that I get this message when attempting to logon to the device: invalid user authentication on the target dev5, the new user created is pretty much a copy of the user 'Owner' except for the password. Any idea as to why I am always getting this "invalid user authetication on the target" message ? Using Codesys V3.5 SP19 Patch 6 + (64 bit) Regards

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Okey, thank you! Do you think it is something in this library, that makes it possible to do the configuration in a PRG? https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/IoDrvEtherCAT.html#id1 I think the codesys modbus libraries support configuration and connection to modbus slaves without having to add the slave devices in the device tree. Just do it from function blocks inside the program. I was hoping for something similar with EtherCAT.

I would like to save the current value as a recipe or load the recipe's value as the current value. And I want to save the recipe as a file or load the recipe saved as a file. somebody help me. (TT)
