Hello everyone, I am building a 3-axis packaging machine. First, I created a virtual axis and connected the knife to the virtual axis using a CAM. I also linked the conveyor system to the virtual axis with GearIn. However, Iβm facing the following issue: when I use SUPERIMPOSED to change the conveyorβs motion, I get a COMMAND ABORTED error. The exact error is: SMC_ERROR.SMC_FB_WASNT_CALLED_DURING_MOTION. Why am I getting this error?

hello. After installing the latest version of codesys (3.5.20) from codesys installer, I had a problem. All my devices disappeared. Both PLCs and IO modules and network devices disappeared from my list. I browsed through the Windows files and I can find them in the programdata/codesys/devices folder. The files remain there, but they are not available within codesys (same error in all installed versions) which in this case are 3.5.16 and 3.5.19. Does anyone know how I can reimport or resynchronize my devices folder again? Thanks

Dear Mr. Kolev, can you please explain a little more: what happens at an STO? I assume the slave axes will be stopped and retain their current position? How, then, do you call MC_CamIn after the STO? Do you restart it with a new rising edge, but on the same master position as before the STO? Which StartMode are you using, is the cam slave absolute or relative, master absolute or relative? Are the slave axes modulo or finite axes? Best regards, Georg Seidel

Guess you could just add two modbus slaves with the same ip, to enlarge the 10 channel limit.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
