Post by cvrettacos-dse on How to reset scroll of a table element ^{CODESYS Forge talk (Post)}
Hello, I would like to use swipe/pan gestures to scroll a table visualization element (CODESYS 3.5.21.10) ona DSE M810 display. The swipe / pan gesture control works fine, however, I cannot figure out how to reset / navigate to the top of the table again with code. I have tried the Scrolling begin variable, and the visu manager is setting it to FALSE right away but the table doesn't actually scroll back to top. If I check the “Scroll elements with scrollbar” box, then the Scrolling begin variable works perfectly, but now the swipe/pan scrolling no longer works and you have to use the scrollbar. Any assitence you can provide is appreciated. Thanks.

Post by vstrom on Codesys v3.5.22.10 - Fail to create a project Archive ^{CODESYS Forge talk (Post)}
Hi to all, I've created a project using the File->New Project-> Standard Project command. Then I've add the object "Visualization Manager" and then tried to create a project archive (File->Project Archive->Save Archive), but it fails with the error "Access to the path 'C:\Program Files\CODESYS 3.5.22.10\CODESYS\Common\3hxi4iod.put' is denied". The idicated file don't exist. First time of use of the new Codesys versionù, I've reinstalled the developement software but nothing change. If I don't add the Visualization part, the archive is created, it's seems to be a problem with the HMI part. Any ideas? Thanks

Post by brouwyka on JSONByteArrayWriter problem? ^{CODESYS Forge talk (Post)}
Hey there! I am currently running into the exact same issue. The JsonData object has all inexes & parent indexes in the way I expect, everything is correctly "linked". It purely seems that the writer is incorrectly parsing said JsonData, not based on parent & child index, but on something else that breaks it and puts things at the root, instead of the specified parent index. Did you ever manage to find a solution, or another way of achieving your JSON composing? I'm currently working on Codesys V3.5 SP19 Patch 7 with IIOT Libraries SL 1.13.0.0, specifically JSON Utilities SL 1.13.0.0 (to send requests to APIs with JSON bodies using Web Client SL 1.13.0.0).

Post by williamcorlin on The future and proper use of CAA.BOLT, CAA.SEMA,.. ^{CODESYS Forge talk (Post)}
I've been moving in the same direction. For new libraries, I'm trying to minimize dependencies on APIs that look like they're being phased out unless the documentation explicitly recommends them. For synchronization primitives like CAA.BOLT and CAA.SEMA, I'd love to see an official replacement or abstraction layer that's guaranteed to remain stable across runtimes. That would make library development much cleaner than relying on platform-specific SysLib* implementations or conditional compilation everywhere. Until there's clearer guidance, my approach has been to isolate the locking mechanism behind a small wrapper interface. If CODESYS changes the recommended API in the future, only that wrapper needs to be updated instead of every library that uses it. It isn't perfect, but it's made maintenance much easier. https://forge.codesys.com/forge/talk/Engineering/thread/e6c20a740e/ https://zapgames.io/

Post by paulpotat on Project size increasing continuously ^{CODESYS Forge talk (Post)}
I still have the same problem with Codesys 3.5 SP18. Initially, my project is ~5 Mo. I work on it for like 3-4 days and it goes up to ~10Mo. If I make an export of the project and import it in a new empty project, it goes back to approximately 5 Mo. Why is it doing this ?

Post by rossanoparis on Upgrading CODESYS runtime from v4.7 to v4.9 using a bash script leads to lose the licences stored in the soft container ^{CODESYS Forge talk (Post)}
System information - Controller: KUNBUS RevPi CONNECT-S - OS: Linux buster 32bit 5.10.103-rt62-v7l #1 SMP PREEMPT_RT armv7l GNU/Linux - CODESYS v3.5 SP19 Patch 2 I'm facing a problem related to codesys licences using a procedure based on a bash script. Such bash script detect the presence of new .deb files and install them on system. My automation solution don't allow to be maintained by dedicated personal, thus even the CODESYS runtime SW must be installed using an "automatic" procedure instead of using the CODESYS tool. remark I've been using the following procedure since the runtime v4.5 without any issue. Before installing the new runtime packages, I need to copy the file CODESYSControl_User.cfg (here attached) because of new section which is necessary to add in order to allow some folders to be written by CODESYS runtime v4.9 Up to now, this has been unnecessary, this is the main difference between my previos bash file and the new one. remark If I skip this action, everythings goes fine, but my CODESYS application can't work as it needs to access some folders on controller's file system. Process - Before the procedure: the licenses are OK (see attached file lic-01.png) - After the procedure: the new CODESYS runtime version is correctly installed, but the software container with v1.19 and all licences disappear (see attached file lic-02.png) This is the synthetic content of bash script I'm using. # Stop runtime sudo service codesyscontrol stop sudo service codesysedge stop # Move the new CODESYSControl_User.cfg file # New configuraton with folders declared sudo mv -f CODESYSControl_User.cfg /etc # Install runtime package echo N | sudo apt-get install -y --allow-downgrades codesyscontrol_raspberry_4.9.0.0_armhf.deb # Install edge gateway package echo N | sudo apt-get install -y --allow-downgrades codesysedge_edgearmhf_4.9.0.0_armhf.deb # Reboot controller sudo reboot Thanks in advance

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

When trying to connect to a Github repository in the Git remotes windows of Codesys, the user can be the account username or the account email, while the password is the Github token. (I know this is an old topic, but I lost some time figuring it out from the guides.)

Post by simotion on Variable indicating axis pending gearing or camming ^{CODESYS Forge talk (Post)}
Is there a variable indicating that a gearing or camming operation is pending? For instance MC_Gearin has beeen triggered, but starting point of master axis to start the sychronisation movement is not reached yet, so the slave axis is just waiting for this. I should be able to differ between a pending and active gearing or camming
