Post by domebruce on TCP communication and TCP Streams ^{CODESYS Forge talk (Post)}
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

Thanks for the reply. I want to be able to check if any dialogs are open of any name. I already have a function similar to what you have send but I don't want to have to run it for all the different dialog names. Thanks

Post by simotion on Variable indicating axis pending gearing or camming ^{CODESYS Forge talk (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

Post by fajean on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
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?

Post by joep on Creating Custom Kinematics ^{CODESYS Forge talk (Post)}
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
