The update via CODESYS Installer fails (admin mode). Anyway I am switching all my POUs from Ladder to ST because Ladder cannot be used like this.

I would check the version of the deloy tool using the CODESYS installer. Sure manually installing works too, but woukd nice to know if there is a problem. Currebt version is 4.21.0.0 of the deploytool.

I pinpointed down 4 possible causes for this compiler error: Bare/empty statements (;) standing alone inside an IF/CASE branch β just removed two instances. The optimizer that tries to inline/replace expression statements may choke when a statement has no actual assignment to extract. A VAR_IN_OUT parameter used directly as a FOR loop's own control variable (FOR X := X TO Y DO) General deep-nesting complexity β every one of my decode routines has the same shape (IF busy THEN ... FOR loop containing nested CASE/IF chains ... END_IF), and the crash trace consistently shows for loop β sequence β ifst β sequence β ifst β sequence regardless of the code change. This raises the possibility that it's not one specific statement but a structural depth/complexity limit in SP22.x's compiler optimizer β which would mean no small code change fixes the issue. Only restructuring to reduce nesting depth, or downgrading the compiler will. Something entirely outside my library files β which cannot not ruled out since the exact stack trace was triggered by a Visualization object, in a totally different codebase. This means the same crash signature can come from unrelated causes. IMHO cause 3 seems the most probable one..

you need to wait for the 4.22.0.0 release which will fix this problem

seems to be an accident but there is a workaround in the Configfile: [CmpSocketCanDrv] AsyncSend=1 and will be solved with 4.22.0.0 Release

Hi. When i scan for devices on the network i get names of the devices. Is there a command to get device name in my programm ? i found : DED.GetDeviceNameString( DED.GetRoot() ); but then i get his name in the programm. not his name in the network.

Hi Georg, Thank you very much for your help and for taking the time to look into my issue! After reversing the directions of A2 and A3, the robot now moves correctly according to the coordinate system. That solved the main issue with the joint rotation directions. However, I still have two issues: When I command the robot to move along the X, Y, and Z axes, the movement seems slightly off, and the trajectory appears somewhat diagonal instead of following a straight line along the commanded axis. The A6 axis also rotates during the movement, whereas I would expect it to maintain its orientation and remain unchanged. Do you have any suggestions on how I could correct the Cartesian linear movement and keep A6 fixed during the motion? Thank you again for your support!
