Post by e60newbie on EVL/EVC auf IFM CR711S ^{CODESYS Forge talk (Post)}
Hi, jain. wir haben mit IFM gesprochen. Sie sagen es liegt an Codesys selbst. Die Daten seien anscheinend nicht konsistent wenn das Projekt zu und erneut geöffnet wird, sei ein probkem von SP11. IFM wird im Sommer ein neues Package rausgeben wo sie auf eine neue CS Version wechseln, dort soll das Problem dann behoben sein. Wir haben zwar einen Workaround rausgefunden aber jenachdem was du in der Safety treibst geht dieser dann nicht mehr. schreib mir zur not eine PN wenn du mehr wissen willst.

Post by wollvieh on Problem while updating to new runtime 4.11.0.0 ^{CODESYS Forge talk (Post)}
okay, no ideas. So i made a new fresh image for the raspberry, so far,so good. Licensing the new image was no problem. And, after having trouble while read write files on the raspberry pi, i found the solution for these file operations with the Variable ForceIecFilePath in the CODESYSControl.cfg file. Some people had that issue discussed in that thread : https://forge.codesys.com/forge/talk/Deutsch/thread/d2df08e587/

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by carohe on VisuNamespace != null ^{CODESYS Forge talk (Post)}
Hello, this error occured frequently over the past couple of weeks. I found out, when adding a webvisu, CODESYS added Visu libraries in the library manager. One of the libraries was the "VisuElemsAlarm" library. In my case it added this one with the version 4.3.0.0. However another library that also contained the "VisuElemsAlarm", used the "VisuElemsAlarm" with the version "4.4.0.0". After changing the Version "4.4.0.0" and uninstalling this version, the error has not occured anymore. Regards, carohe

Post by ofey on EtherCAT fieldbus ^{CODESYS Forge talk (Post)}
Okey, thank you! Do you think it is something in this library, that makes it possible to do the configuration in a PRG? https://content.helpme-codesys.com/en/libs/IODrvEtherCATDriver/Current/IoDrvEtherCAT.html#id1 I think the codesys modbus libraries support configuration and connection to modbus slaves without having to add the slave devices in the device tree. Just do it from function blocks inside the program. I was hoping for something similar with EtherCAT.

Post by food on Beaglebone Black OPC-UA Server ^{CODESYS Forge talk (Post)}
Man, this was a long time ago. I think the problem probably stemmed from not loading the certificates from the client and the server on the server and client respectively in the correct manner. I believe I ended up getting around it just by removing all security on the server. In the end we did not move forward with that architecture so I never had to actually fix it.

Post by rossanoparis on RevPi CONNECT+, CODESYS, EtherCAT master "Filedbus lost synchronicity" ^{CODESYS Forge talk (Post)}
Hello @rmaas I assume, you've already verified and tuned everything regarding the EtherCAT network. In my case the problem was due to a wrong core assignement. I suggest to not use the core #0 for your EtherCAT task. The OS realtime patch, which is present on RevPi OS, uses the core #0 for its porpouses and it mustn't be used by any other task which requires realtime and deterministic features. regards Rossano

Post by dkugler on Alarm State Icon ^{CODESYS Forge talk (Post)}
thank you for pointing me to this "bug"!! I haven't recognized, the bit is reset after the first alarm is gone. I use this only for warnings, so it's not a drama, but was not correct in the past. I solved it now simply stupid by counting up a variable every time an alarm appears and decreasing it if an alarm is gone. The "warning lamp" is activated by checking the counter is > 0 The nice side effect, i'm able to show the number of active alarms in the state line now.

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
https://forge.codesys.com/forge/talk/Engineering/thread/92c913bf7c/ Solved by changing the ethercat master version after reading the thread linked above. I think I need to read up on why this happened. I understand that placeholders should point to a particular version for obvious reasons however what has occurred in this instance is different. The example project was released as a "project archive" but it seems to load differently based on what I've got installed in my repositories. I'm going to dig into that tomorrow but any advice is welcome.

Hello New W11 machine. I've tried installing and the 'Codesys installer' appeared, which basically failed. This was the exe from the Store. I've now tried installing with an old copy of SP17, which didn't try and use the Codesys installer, but has hung at the 'Install all packages added to the setup' stage. Has the exe been updated to use the Codesys installer? What is the installer? Do we think it'll work on w11? thanks, Paul

Post by pmolke on Datenkonvertierung für ein SPS-AO-Modul ^{CODESYS Forge talk (Post)}
Hallo, du solltest dir angewöhnen Präfixe für die Datentypen zu nutzen. Dann ist das auch lesbarer. Aus value wird rValue für ein REAL oder wValue für ein WORD. Daher ist jetzt nicht ersichtlich mit welchen Datentypen du dort arbeitest und was die Bausteine an den EIN- und Ausgängen erwarten. Du kannst aber explizit eine Typkonvertierung durchführen indem du am Ausgang noch einen Baustein "TO_WORD" setzt.

Post by andre-luis on Check if Codesys runtime is on 'Running' or 'Stopped' state? ^{CODESYS Forge talk (Post)}
Just to share, for those who as me are seeking for this and had found no information anywhere in this World: Every time I stop/start the PLC runtime ( turning into 'Stopped' or 'Running' state ) the 'CODESYSControlService' appears at the Taskmanager list, which could suggest a straight correlation. I was expecting a clever solution, but this one solves for while.

Post by mubeta on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Yes, this point is part of my misunderstanding. Why, after the execution ot the motion FBs is set to FALSE and exsecuted at lest one time, it must be continuosly called, even if the motion control it's take from another subsequent instruction. This is what I really don't undertand, but what in fact it's happening. For example, in case of stopping a MoveVelocity FB, then Halting the motion by the related FB, the axis at spot goes into error. If there was bad trigger management, the various instructions would NEVER work.

Post by mikek10 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
I was answering your last paragraph Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work).

Post by installwhat on Initialization of POUs (FB_Init) ^{CODESYS Forge talk (Post)}
Hi I was wondering if there's a pattern I can employ to acheive what you're doing but with a "reference to" and also allowing for online changes? Someone told me that the new beckhoff keeps references safe during online changes but all the documentation I've found suggests that's not the case. The easiest thing is to use fb_init for normal vars and pointers and references can be added in the function body every cycle and this allows for method calls after so far as I can tell.

I can confirm that at my 4ms EtherCAT Master the frames per second is equal at round about 500 with Codesys SP19. The same program at SP16 it was at 380-430 f/sec. for me it will be interesting too, whats the reason is for this high frame count/sec? I havn't had the time to use a paket sniffer and analyse all the frames. I can't help with your other questions, sorry.
