Post by timvh on Troubles with using CAN API ^{CODESYS Forge talk (Post)}
In the example project, you can see that a CAN.CANAreaReceiver is used which has an VAR_IN_OUT reference to a RECEIVER_AREA structure. This structure has a dwIdStart and dwIdEnd to filter a range of ID's and process them through the referenced msgProcessor.

Post by climblinne on Calling OPC UA Methods from UaExpert ^{CODESYS Forge talk (Post)}
So I found the mistakes. First I forget to deactivate "Use access rights defined in the user management". And also I used in "UaModeler" a project name with whitespaces, which lead to a wrong namespace name.

to fix this I used a sp17 codesys and changed the project setting softmotion version to 4.6.2.0. I'm not sure if I should have had such difficulties but it works now.

Post by faceplant on Comparison via CLI is broken ^{CODESYS Forge talk (Post)}
Hello! I am trying to compare 2 projects via the --compare CLI option. In the docs for the --compare option, it describes the usage as .\CODESYS.exe --compare "project path 1" "project path 2". I store my projects in WSL2 on my windows machine. Since CODESYS is happy to open those projects via a path like \\wsl.localhost\home\project.project. So, to compare, I use the command .\CODESYS.exe --compare "\\wsl.localhost\home\prog1.project" "\\wsl.localhost\home\prog2.project". This results in CODESYS just opening the project and starting, not comparing the two projects. No errors are thrown, and I know the paths are correct since I can open both independently in CODESYS, and I can compare them manually through the CODESYS UI. I have also tried moving my projects to the Windows 11 OS and still have the same issue. CODESYS opens the project and does not actually compare them. I am using CODESYS profile v3.5 sp20 patch 1. What is the correct way to compare 2 projects using the --compare CLI option?

Post by andre-luis on Check if Codesys runtime is on 'Running' or 'Stopped' state? ^{CODESYS Forge talk (Post)}
Hi there, I'm running the Codesys runtime on Windows 64 and I need to know if it is on "Running" or "Stopped" state just after a system crash. The following commands works perfectly well to (re)start it... net stop “CODESYS Control Win V3 - x64" net start “CODESYS Control Win V3 - x64" ...however I'm unable to determine when it is required to be call; I mean, by checking the System Tray icon, it is possible to know if it is on "Stopped" state, but I wanted to run a .BAT command to retrieve it. How can we do that?

Post by yoeri on Refresh visulization realtime ^{CODESYS Forge talk (Post)}
Hi everyone, I need some help with displaying an image (test.png) on my device. Initially, showing the image is straightforward. However, I want to be able to update the image dynamically. My goal is to send updated files via FTP to the device, and have the display automatically show the latest version of the image. All images will be sent with the same name (e.g., test.png). Currently, I can see the updated image after sending it via FTP and performing a warm restart, but I'd like to achieve this in runtime, without having to restart the display or application. Does anyone have suggestions on how to implement this? Thanks in advance!

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks

Post by bruceae on Special Characters ^{CODESYS Forge talk (Post)}
Hello, I am fairly new to the codesys environment. Is there a reference chart that I can look at in order to write special character in a string? The Special characters that I need to inclue inside the string are as follows; Null Bell Carriage Return I have a TCP_Write command that I am sending to an external device. In order for that device to function properly it needs to see the string with the null and bell characters as the header, followed by the desired command, terminated with the carriage return. Any reference sheet or how to write this in the actual string would be greatly appreciated.

Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?
