Post by timvh on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
If you are a vendor of controllers and want to have your own CODESYS Runtime on your device, then you need to contact the CODESYS Sales team and ask for the runtime Toolkit. For resellers of CODESYS devices, this can be interesting. If it is only for a few devices, then why not just take the standard runtime?

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.

Post by esave on Stepper Drive with Ethercat ^{CODESYS Forge talk (Post)}
Hello everybody I am new into Codesys. I have a stepper driver (EM3E-556E) from Leadshine. I want to controll the stepper driver via EtherCat to a ST programm but I dont have any function block or anything that i can use. I only have the XML-File wich I loaded. With it I implemented the drive as a Ethercat slave and now I see these variables. (See picture) I dont know how to controll the stepper drive. And the manufacturer doesnt provide support for me. Can anybody help me or atleast tell me how they would do it?
