Post by bryandimino on OPC Da Server Code Meter Issues after Enabling License ^{CODESYS Forge talk (Post)}
I'm trying to get the OPC server setup on my machine and currently I'm not having luck. I went ahead and got my license setup. However when I go to run WinCoDeSysOPC.exe I get an error message that I don't have the code meter licenses installed. Does anyone have any ideas on how I can fix this issue?

Hello. I am using TI AM64x evaluation board TMDS64EVM. It has 8 leds connected via I2C to SoC.I wanna control them via codesys GPIO device. Is that possible? If so how I can do it. I had no problem installing codesys runtime, and running program on device. But when it comes to GPIO access, It couldn’t make it.

I am using MemCopy Function for this example: https://www.youtube.com/watch?v=DeTCT5Vyn28&t=482s It is from library WagoSysPlainMem. I want to use this for an MQTT example. However, Codesys is complaining the block does not have outputs. How to fix this?

Hi, Im struggle with making custom button. The idea is simple grey light bulb after touch (input var) it changes to yellow but shows output var status not switch status. So if light is physically on, switched by physical switch, bulb is also yellow. How to do it?

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.

I also had this problem connected CODESYS to UAExpert for the first time. In the device, I need to allow anonyomous log in. Follow steps 14 - 17 of the following tutorial: https://docs.factoryio.com/tutorials/codesys/setting-up/codesys-opc-ua-sp17/#creating-the-project

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 ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

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?
