Instead of complete VM's, you could also create a sandbox installation using the CODESYS installer.

Hello, I'm doing some tests with TCP communication using Reader, Writer and TCP_Process components from NBS 4.0. I'm having a really hard time finding documentation and examples on these components. I found a very simple and incomplete example here: https://forge.codesys.com/prj/codesys-example/nbs/home/Home/. The documentation is also insufficient: it only provides the names of the FBs, Methods and their parameters, but no descriptions about how to use them. Do you have any suggestions on where to find more support? More generally, why is the free online CoDeSys documentation so poor? What do you think? Thanks Domenico Canavero

CODESYS Forge

(Post)
Is there a variable indicating that a gearing or camming operation is pending? For instance MC_Gearin has beeen triggered, but starting point of master axis to start the sychronisation movement is not reached yet, so the slave axis is just waiting for this. I should be able to differ between a pending and active gearing or camming

Hi Under tools->customize I have added the command "Generate ethercat xml" to my project so that I can export the configuration as an xml file. I can't find a way how to run that command from CLI, is that even possible and if a script is needed I would appreciate an example ?

Hi Ricardo. I was having the same problem with Codesys and a Raspberry Pi 2W while using the GPIO uart. Your post helped me a lot. Thanks! But could not understand why MODBUS parity bit makes Codesys MODBUS COM driver stopping to work after first request transmission. Did you see this @eschwellinger ? Regards, Nelson

We are having issues right now, and I just stumbled on that post. It seems to me you are saying your Linux ARM control is RPi 5-compatible, but the one you sell specifically for RPi is not. The fix you are proposing requires customers to re-purchase a CODESYS licence. Is there a time frame for that to be fixed?

Hi John, Coincidentally I also tried creating a custom kinematics model for a parallel delta2 like the picture I added. bipod_rotary doesn't seem to do the job. Have you accomplished a working model? I'm stuck on error: "smc_cp_invalid_path_elem" while im certain my math is correct since we made it work using single axis movements. Maybe we could help each other Best regards, Joep

Sorry, wrong expression. You have a 64bit system, so do I. You can also use the 64bit runtime, but most bib and commands are 32bit and are not properly supported. I had read somewhere that there are problems with I2C. That's why I recommend switching to PI_SL and using the correct gpio.

Not knowing exactly what you want to accomplish, you can try to use VAR_INPUT MyVar: POINTER TO BOOL; END_VAR MyVar contains the address of your referenced variable, and MyVar^ dereferences it allowing you to access the value. If this doesn't meet your needs, could you add more detail on what you are trying to accomplish?

I encountered the same problem. (Windows10 x64 single language OS). As @eschwellinger mentioned, I uninstalled the latest EdgeGateway version and installed version 3.5.20.0. Now, when I right-click and select "Allow Edge Gateway...", Config mode is activated without any error or warning window and I do not need to manually type [CmpEdgeGateway] for EdgeGateway version 3.5.20.0.
