I have installed: SM_Drive_PosControl 4.18.0.0 and SM_Drive_RaspiStepper_Direct 0.0.0.7 and SM_Drive_RaspiStepper_PulsDir 0.0.0.7 And when I "Generate Code" I immediately get 6 errors (see attached file) What can I do?????

Is there perhaps a place where I can see examples of programming with different instructions? This would be a great help. Maybe there are some places where ready-made programs are posted that can be downloaded and tested? /Klaus

.. try to use this projectarchive for the Stepper. In case you search for SoftMotion Examples: "c:\Program Files\CODESYS 3.5.21.X\CODESYS\CODESYS SoftMotion\Examples\Tutorial\"

After carefully studying the documentation, I have a question: is a second hardware-independent time source required for the correct operation of the VirtualSafety system?

Thank you for your response. Is there documentation for the commands? I spent a lot of time trying to figure this out. I have a potato computer at home, so I'll have to test this later.

To simplify your problem you shall not select dongle and get dongle errors. Do as shown In some cases you need 2 different licenses depending on the metrics. And yes the system gives not always give proper error messages when you try to reinstall a license

Are you sure you need to read holding registers? Have you tried reading input registers?

Kurtk, I am working through a very similar scenario. I am curious if you have had any success since your post in implementing dynamic modbus configurations? Thx!

...hört sich für mich eher nach Hardware problemen an, kann mich auch teuschen. Würde immer ins "SPSLog" schauen - vielleicht gibt da noch mehr info auch für den Fall das die Runtime nicht hochläuft.

ich hab da noch eine Frage zu diesem Thema, wenn in [SysFile] PlaceholderFilePath.1=/tmp, $TMP$ z.B /home/pi angegeben wird gilt das dann auch für die darunterliegenden Unterverzeichnisse z.B. /home/pi/MSG oder müssen diese immer separat angegeben werden? und was bedeutet das , $TMP$

Did you check the communication with a sniffer ? (ex. Wireshark) to check if the holding get to zero by a wrong writing (client initialization?) o something else?

Hi. What type of PLC do you have? What activation method do you use? What license ticket did you purchase and want to activate? Can you describe the process you followed step by step?

Downloaded and installed edge gateway 4.19.0.0. Unfortunately same behavior: "Control for Linux SL" NOT shown in drop lists on either "Deployment" Tab of tool "Deploy Control SL", or as "installed packages" on "Operation" tab (only "CODESYS Edge Gateway for linux" is shown).

Am I alone in this? Is this a known fault? Should I look for the reason of the lacking update option for "Control for linux SL" in my system or is it a potential fault in the codesys system?

Hi could you check if this really exists in 4.19.0.0 deploy tool? In your case architecture is missing- see my configuration

I need the same issue. In my application TCP server on raspberry (codesys) should have UnitID 1. But it only works when I am requesting with UnitID 255. And my application can't work with this parameters...
