Post by josephbourgeois on tracking out product ^{CODESYS Forge talk (Post)}
Hi everyone! I synchronize the operation of the tripod and the conveyor. I have a problem with the product tracking algorithm on the conveyor (PCS_1). Sometimes I need to stop tracking a product on command without completing the operation. I do this using MC_GroupStop. But when I need to start moving in WCS again (using fb movelinearabsolute), I get a tripod kinematics error - SMC_CP_INVALID_ORIENTATION (Invalid orientation (non-orthonormal matrix or non-unit quaternion, internal error)). MC_ResetGroup does not help. What could be the problem? Has anyone encountered this?

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 durstloescher on Codesys Input Detector ^{CODESYS Forge talk (Post)}
Good morning, I am currently working on implementing a display dimmer. I want the display to dim after X minutes. This works so far. The implementation is done via the Linux subsystem, to which a command is sent to dim the display. However, my problem is resetting the timer when input is received. I want the dimming timer to be reset with each click/touch. Unfortunately, I can't find a suitable solution for this. Are there any ways to do this? Codesys v3.5 SP19 Patch 2

Post by kleeswi on SysFileOpen does not work after update to V3.5 SP19 Patch 5 ^{CODESYS Forge talk (Post)}
I use the function SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_WRITE, pErrorFileOpen); to open and write a file. Since the update from Codesys V3.5 SP17 to V3.5 SP19 Patch 5 it does not work anymore. I first had SysFile.SysFileOpen(sFileNamePara, SysFile.ACCESS_MODE.AM_APPEND_PLUS, pErrorFileOpen); in both versions. hFile_Test is a pointer to byte. It gives an exceptional error when dereferencing the hFile_Test pointer. Edit: I use Codesys on a Raspberry pi

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by dagsupport on CAA SerialCOM - hCom Reset max value 1023 ^{CODESYS Forge talk (Post)}
Hi everybody We are currently working on a project with an RS232 serial COM interface and using the CAA SerialCOM library. We have it working fine reading and writing data, although we have found an issue we cannot resolve and any suggestions would be helpful. We have noticed that after a while the RS232 stops working. We have tracked this down to the HANDLE hCom keeps increasing and when this reaches 1023 the COM returns an unknown error "5003". Is there a way to reset this hCom reference? Thanks Richard

Post by alex2 on Codesys SVN ^{CODESYS Forge talk (Post)}
Hello Everyone. I have a question about the SVN module on Codesys. I am using Codesys V3.5.10 and installed Codesys SVN 4.2.5.1 but when i try to connect my SVN to codesys i have a message saying that there is no license for accessing the Url. I searched on the codesys store and it seems that "CODESYS Professional Developer Edition" is needed? Am i right? Do i also need to buy a USB key? Is there another edition but only for the SVN? I thank you in advance for your answers.

Don't set on SVN. The service phase has started in March 2024 and will be discontinued in 2027. We actually use SVN and have to switch to GIT in the future. As I informed, there is no way of getting a single SVN or GIT licence. I' dont understand, why Codesys forces us customers to pay for an expensive Professional Edition paket from year to year using only one part of it! If you find a way to buy a single licence, let me know.

Post by gseidel on Discontinuity of A/B/C axis movement. ^{CODESYS Forge talk (Post)}
Hi jonasz, you already solved it, I'm answering here for the sake of others with a similar question. You can provide the slope of the A/B/C axis with the U/V/W word. See example 3 here: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cnc_din66025_additional_axis.html If you don't want to change the G-Code, the function block SMC_RecomputeABCSlopes can compute the slopes automatically. https://content.helpme-codesys.com/en/libs/SM3_CNC/Current/SM_CNC_POUs/SoftMotion-CNC/SoftMotion-Function-Blocks/SMC_RecomputeABCSlopes.html Best regards, Georg

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

Does anyone know how I can select a specific POU in the navigator? Or how I can open a specific POU? I can retreive the guid of the POU. Thx

Good morning, I'm trying to open a project but codesys tells me that there are certain packages that I don't have and that I need to download them. Once the installation of the packages begins, it shows me a error that the signature of certain packages does not correspond to that coming from the accepted installation context. Do you have a solution to my problem please, it is very urgent in my work. Sincerely

Hello, I'm quite new here. I would like to create a new HTML5 visualisation. I have already imported some templates via the visualisation elements repository, this worked fine. However, when I want to open the html5control.html in the editor or create a new project myself, I always get this error: default filesystem storage could not be found. Did you add storages.plugin to the profile? I can't find this plugin. The Package Designer (V4.1.0.0) and Codesys Visualisation (V4.5.0.0) plugins are installed Can anyone help me? Thank you very much!

Post by nano on How to access to variable value through symbolic string name ^{CODESYS Forge talk (Post)}
i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

Post by durallymax on VAR_INFO from inside of a FB to get info on the instance. ^{CODESYS Forge talk (Post)}
The help link appears to be broken. When I implemented something similar I had to add {attribute 'reflection} above the declaration of the FB with {attribute 'instance-path'} above the string VAR that would contain the path. Then wrote a function to trim off however much I wanted removed by searching for periods, then formatting it with spaces at the periods and removing brackets on arrays while also breaking up the PascalCase to present it a bit nicer for the end-users.

I'm building up a 2nd PC to match an existing developer PC. Installed the same SP and Patch levels but when I open a project that was created on the existing PC, Codesys complains that it's not the same version. Attaching a screenshot..... What else is there to match? Also, can all of the libraries that are on the existing machine be copied from it to the new machine and if so, how? (So I get the same versions) Which files/folders do I copy? Thanks! -Farren

Post by timvh on KeyPad Function in Visualization to fill a table ^{CODESYS Forge talk (Post)}
Create an array of STRING and 1 INT variable, e.g.: asMyString : ARRAY[0..9] OF STRING; iIndex : INT; Then place a "Table" object in the visualization: - link this to the string array variable. - Check the option "Use Template" - Then in the Input Configuration - add the "Write Variable" command Somewhere else add a "Combobox, array" - link this to the same array. - And link the index to the INT variable. In the Combobox, you can then select one of the strings from the array. The index variable will indicate which selection has been made.
