Hi, Recently, I purchased a license for PubSub communication from the CODESYS store. Unfortunately, after installation, I couldn't find any example code in the files. Is there anyone who can share such an example/send links or help with writing such communication in ST language?"

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.

Hello everyone, I have a problem. Codesys 3.5 P19 works without any problems. However, P20 is not usable, after starting it hangs "no response". A new installation didn't help either, unfortunately I can't find a more precise error. BR

Thanks for your quick help. It's working until I do a reboot of the raspberry PI. After that it goes back to 2024-04-20. How's that possible?

Additionally the license is loaded on the soft storage for my device but it shows up as invalid. I just activated it today.

Hi, I tried posting in the discussion for the HTTP Client example but perhaps that is not monitored? I have been using http client successfully for approximately 12 months, however in recent weeks I have begun to get TCP_INIT_ERROR when attempting to communicate. The only resolution seems to be power cycling and then the connection begins to work again for a time. I am not aware of any changes to code or libraries between working ok and now. Cold reset does not resolve, only power cycle. It seems the error from NBS.TCP_Client is 6002 which I think is invalid_addr However the address is the same when working and not working?

Thank you so much. This worked. Waht im trying to do here is to automatically tag each sensors, valves and so on. There is a preatty nasty tag system i working on. "_320" is not alloved. I can have a tag "+4f=320.004-RT001V" In codesys I want to build the FB in folders. -4f | --320 | --001 This is the system structure. Inside here is all of the sensors and so on. But with Codesys, I cannot tag this like this. So what I'm trying to do now is to Make a folder for the building "4f" and one for the system "320", and a POU _001. Is there a way in init to get folder names?

Post by e13740e on Сalling the context menu from the keyboard
CODESYS Forge
talk
(Post)
Hello. I have a question for you, perhaps you have an answer to it. Regarding calling the Context menu from the keyboard in Devices, specifically calling the context menu window from the keyboard via an assigned combination. Goal: to have the ability to navigationally add internal Objects (Methods, Properties) to Function Blocks from the keyboard without using the mouse. The Codesys environment interface does not allow Windows access to this via Shift+F10. Externally (outside the Codesys environment), the hotkey call for the context menu (Shift+F10) from the keyboard works in various environments, but at the same time, in Codesys it does not (it doesn't work). I have already tried various options on my own to achieve this (but unsuccessfully): Tools\Customize\Keyboard\Objects (the set combination does not give the desired result) Tools\Customize\Keyboard\Objects... (the set combination is extremely useful as it provides access to adding objects directly to Devices but does not provide the ability to add an internal object (Method/Property) to a Function Block). Thank you in advance for your help!!! P.S. I have already started trying to implement a script-based solution to call the context menu via AutoHotkey - by relocating the mouse cursor to the area of the navigational selection with a subsequent call of the context menu on it and relocating the mouse cursor back to its initial position. And in order not to "reinvent the wheel," I am writing this request to you!!!

Hi, does anyone has a solution for this issue. I've the same problem. I've implemented a very simple client based on the Modbus Examples and connected the soft PLC to a Modbus Simulator.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
