Hello Edwin, I sent the info through CODESYS store my question, as I was afraid that I could be exposing sensitive information here in the forum. Thank you very much!

It seems I misunderstood "Toggle color". It's only applicable for the Symbol "FRAME". This part is working fine. See also attached archive.

CODESYS Control for Raspberry Pi MC Does CODESYS use its own native driver for I2c? I have a python script communicating with a device simultaneously with a CODESYS doing the same. The bus is not saturated. But I get many read errors

Hi eschwellinger, Thanks for replying, but I'm not shure if I got it right. Do you mean that I have bad configuration on my CODESYS config file? Or in my project? Thanks in advance!

Hello everyone, I have a problem. Codesys 3.5 P19 works without any problems. However, P20 is not usable, after starting it hangs "no response". A new installation didn't help either, unfortunately I can't find a more precise error. BR

I'm not sure I understand what you're asking, but I don't believe a function block with this behavior exists in the default libraries. I think the best solution would be using multiple and/or blocks or make your own function block.

Hi, which CODESYS IDE version are you using? I think it's fixed in >= SP19 patch 7, maybe also in SP19 patch 6, but I'm not sure.

@davidking, can you be more specific about where exactly "Compiler Defines" is located. I'm using Codesys v3.5 SP21 Patch2 and cannot find this Compiler Defines option. In the menu Project -> Project Settings there are Compiler options and Compiler warnings, but that is not it.

Hi tommyk-mar, do you call SMC_SmoothPath after SMC_NCIntepreter? Both G51 in the G-Code and the function block call are needed. You can see how this can be done in this example: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_example_cnc_3.html Best regarsd, Georg

Post by adamrobotic on llcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008 ^{CODESYS Forge talk (Post)}
Hi All, Recently I have been experiencing a issue in CodeSys SP16 Patch 3, with a exception which comes up after I have made several online changes. callcallback() iec exception caught cmpid=0x00000002, eventid=0x00010008, after I experience this fault then I receive a error message for any subsequent online change "online change failed, no task gap within 10000ms". To recover either the controller needs a orgin reset, which will allow online edits thereafter until falling back into the loop. I am using a TURCK TX707 product which is controlling robot trajectory, We have hard coded the coordinate data rather than using persistence variables so hence the need to do online changes consistently. I have read on the forum other people have experienced similar issue with the online task gap, but I have no task which have same priority and also monitored the CPU usage and have not seen it go above 13%. Anyones help would be much appreciated, thankyou.

Post by aseitzinger on CODESYS Control for Linux SL on virtual machine? ^{CODESYS Forge talk (Post)}
Hello, there in different information available regarding the possibility to run CODESYS Control for Linux SL on a virtual machine. https://forge.codesys.com/trg/linux-sl/home/Home/ says CODESYS Control for Linux SL is a runtime system, which can run on any Debian based X86 PC, VM or Cloud container... https://store.codesys.com/media/n98_media_assets/files/2302000005/3/CODESYS%20Control%20for%20Linux%20SL_de.pdf says CODESYS Control for Linux SL can not be used on virtual hardware Currently I run the package mentioned on a virtualized debian machine running in PROXMOX Virtual Environment 7.4-17 and apart from huge jitter it runs without problems. The CODESYS key is passed as a USB defice to the VM. I wonder why there are different statements regarding the suitability in virtual machines and if the jitter would be reduced by installing CODESYS runtime on the host installing CDS runtime on the host and using a preemptive kernel (if available for the PROXMOX installation leaving CDS runtime where it is (on the virtualized debian machine) and install a preemptive kernel on the host and on the guest... Any advice is appreciated. Greets Arno

You need to create a function around this function to check the dialogs you use in your program. That's the way i have done it.
