Here is the help sections for visual elements rectangle. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html Under "Font Variable" there is "Color" which is a Dword, you can make a variable that changes colour within your code to the color needed. Note the format for the Dword variable is: colorVariable := 16#TTRRGGBB Where: TT = Transparency 00-FF RE = Red 00-FF GG = Green 00-FF BB = Blue 00-FF https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_animate_color.html

Hello, I am encountering an interesting problem as below in SP20patch5 variable definition area. I think this is a bug. As can be seen in the attached screenshot, it assigns the same %MW or %QW address to all elements of the array. I hope Codesys team can solve this problem in the next version. Best regards, Imdat

I'm programming an HMI, and on a settings page I have external buttons allow the operator to tab between various elements to select which one they want to adjust. I then use "Input Configuration" > "OnMouseClick" to select which variable to adjust. The problem is, when adjusting the variable the pointer will move to the other elements within the tab order. Is there a way to pause or prevent the pointer to move to the other elements when a variable is TRUE?

I need to be able to update (change) the interface of an IO-Link device at runtime. The reason is the connected sensor can be selected at runtime, and some sensors we use have a 2 byte IN interface, others have a 4 byte IN interface, others 16 byte IN, others 16 byte IN/OUT (see attached screenshot). Is it possible at all? When yes, which function should I use? Thank you!

I need to be able to change (set) the DeviceID of an IO-Link sensor (see DeviceID.png) at runtime. I tried with both ProfinetCommon.PN_PortConfiguration and ProfinetCommon.IOL_PortConfiguration, but I get an error for both when I try to read the port configuration (see PN_PortConfiguration.png). Does one of those FBs is the right one for my purpose? Do I possibly make a mistake when assigning the parameter IOLD_ID/IOLM_ID?

Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Hello @community, i hope i will get a solution for following problem. I am using CODESYS v3.5 SP18. At the visualization i dont see the action for the element which i could set below the InputConfiguration-Section. I found a topic about that, but this could be resolved through activate the Advanced Checkbox. But in my case it did not work. See the screenshots. I hope someone know this problem and have a solution. Thank you in advance.

Hello all, could you tell me whether I need an additional license in order for v3x64 to execute the DLL? Is there some manual on how to proceed? Other than the rather generic message loading Component failed Lib_XMATH.dll I have no further hints. Many thanks for your feed back. PS: I tried a similar experiment (i.e. generating a native dll for windows and having it executed by the Python VM this worked without an issue).

I'm having a serious issue with codesys-pro/git, because everytime I load my project I get around 40 unstaged changes with equal objects. If I only commit everything along with my real changes I strugle to locate them later. I've tried creating a new git repository, it didn't work. I've commited everything, it kept appearing. I've tried rolling back everything but it also didn't work. Does anyone know why this happens and how to manage it?

I have a Codesys-based Eurotherm E+PLC400 connected to Codesys HMI SL for visualization. I am also bringing in several Pressure Indicators via the Ethernet. Everything works; however, the Pressure indicators sometimes read a negative value. When they do, the displayed value on the screen reads "65532." While I know what it represents, the customer freaks out and wants it to read "0" or a negative number. The value comes in as an integer, just in case that matters. Does anyone have any ideas?

Update: I still have no idea what was causing my issues, but it went away as soon as I identified that another device on the CAN was generating a Sync message at 16#7F. Changing this to be on 16#80 made the problem go away. I have no idea why this solves the problem and would love to hear from anyone who knows why these two things might be related.

Thank you for the suggestion. There is a certificate created in the quarantine directory relating to the URL used for the webclient FB. This certificate should have been valid as it was created only the week before this problem was encountered. I investigated a separate location using the same https URL and it has 2 certificates in the same quarantine directory, 1 is created almost 200 days ago, the other over 100 days ago. There have been no similar problems encountered with these certs or https at all.

After updating my Codesys to later versions, it seems my device repository no longer lists the proper runtime devices, nor ethernet adapters, or other previously installed device descriptions. What needs to be done here? Do I need to uninstall and do a clean install? I am now updating to SP21.1 to see if that fixes it. Any tips what I am doing wrong here are much appreciated. I don't see codesys control win, or have the ability to add an ethernet adapter in my project.

Hey tk96 Thank you for your help. I have found the reason why fbreader stuck. It was not the program but it was the gcode itself. G21 command blocks the reader. And multiple G codes in a line also blocks the reader. My code was: N010 G21 G17 G90 -> Blocked the reader When i change it to: N010 G90 N020 G17 Then it worked. The only thing i did not get is why the reader did not thwor error. ErrorId was SMC_NO_ERROR. Anyway, it is now working. Thanks again.

Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic
CODESYS Forge
talk
(Post)
Dear @gseidel, @tk096, I noticed that with SoftMotion V4.18.0.0, if a new axis is added to the project, the ramp type selection defaults to "Quadratic". In all previous versions, the velocity ramp type selection was "Trapezoidal". This causes some unexpected issues in projects with SoftMotion version V4.18.0.0 for newly created or newly added axes to existing projects. Is it possible to reconsider this situation in the next update and set the velocity ramp type to "Trapezoid" by default again? Best Regards, Imdat

I would definitely try using the "Reconfigure" function block from "CAA Device Diagnosis@ library. https://content.helpme-codesys.com/en/libs/CAA%20Device%20Diagnosis/3.5.17.0/CAA-Device-Diagnosis/Function-Blocks/Reconfigure/Reconfigure.html#:~:text=This%20function%20block%20reads%20and,take%20effect. Although I have not tried it with Modbus, I had great success with EtherNet/IP, Profinet and EtherCAT. You can also have a look at the other functions in this library. There are useful functions to help iterate through all the nodes under a master node.
