Post by ralfki on User management ^{CODESYS Forge talk (Post)}
Hello eschwellinger, at first thank you for your answer. So the only ways to activate the user management are CodeSys delevelopment enviroment and the Codesys Automation Server. So there is no function to activate the user management via code? Do you have an idea how to get back the users when somebody replaced the PLC. Our customers have only our own developed visualization and they also don't want to install further softwares. Do you maybe have a solution for this

Post by mostafa-beshr on implementing continuous movement in Codesys ^{CODESYS Forge talk (Post)}
Hi everyone, I’m working on implementing continuous movement in Codesys, but I've run into some trouble. I've tried using ALL SM3 Basic and SML without success. I’m specifically looking for a library that supports continuous updates and can fetch values from a server in real time. Does anyone know of a library or approach that fits these requirements? Any advice or suggestions would be greatly appreciated! i read plcopen documentaion as well as codesys Thank you!

Post by timvh on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
The RTE will take the RTE license. The HMI will take the HMI license. For the Application Based Licenses, the Runtime will take the smallest which is required. So if you have an application running EtherCAT and no visualization, only the Control with support for EtherCAT is used. If you have another runtime which requires the visualization, it will take the smallest Control license which is required and available + the smallest visualization license which is required.

Post by bzzz on Connect WS2812B Light Strip to CodeSys via RasPi ^{CODESYS Forge talk (Post)}
Hey guys, I have a RasPi and can control my WS2812B (addressable light strip) via Python. The lightstrip is this one: https://core-electronics.com.au/1m-rgb-led-strip-ws2812b-144-per-meter-white-strip-weatherproof.html What I would like to do is to control it directly via CodeSys through the plc on my RasPi. I know I can run a python script on CodeSys, but I'd like to avoid doing that. Is it possible, and how do I do it? Is there a library that does this?

Post by pernockham on Is there a pragma for init/instantiation of local variables in FB (like in Methods) ^{CODESYS Forge talk (Post)}
Im using a pointer as input for a FB and for convenience I like to use 'referenced' variable internally. I use this setup in methods which works because internal variables are instantiated for each call. In a FB these variables are instantiated and initiated for the first call only. Is there a pragma/attribute available that changes this behaviour to mirror a 'method'-call?

Post by dsa28 on EL6910 as a PROFIsafe F-Host in Codesys ^{CODESYS Forge talk (Post)}
Hello All, Does anyone have experience configuring a PROFIsafe communication between EL6910 (F-Host) and and a F-Device in Codesys? I would expect that the PROFIsafe configuration process would be pretty similar as the FSoE configuration. Although, when an F-Device is included under PN-Controller, Codesys doesn't allocate a PROFIsafe logical device automatically under EL6910, as it happens when a FSoE slave is added under EtherCAT master. I thank anyone in advance who can help me on this.

Hello everyone, i'm having some problems commanding AS1060 step motor with EL7041 (rev22) drive. With motor i've also the incremental encoder (05.2420.1230.0200.5009). I can correctly move the motor in "Position controller" operating mode with the internal counter. The problems start when i set the Encoder in feedback type or i change the operating mode. Does anyone have experience with these two terminals and can give me some advice of main parameters to check or change? Thanks everyone

Post by askic on PLC error log help ^{CODESYS Forge talk (Post)}
Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
No errors in any condition. The function terminate correctly with the 'done' bit. Now I leave the machine and I don't know when I will be there again. The assumption you made I had considered. The operational limits of the axis are all fit for purpose, and this function should operate virtually without even noticing the motion limits. In fact in practice with the axis at low speed the function corrects any numerical value of the position in the range 0 ... 360° without any problem whatsoever in a single PLC scan cycle.

Hello, I have found the following instruction in the online help( https://content.helpme-codesys.com/en/libs/CmpSupervisor/3.5.17.0/SupervisorOperationSetTimeout.html ): Sets a (new) timeout for the given operation Supervision must be disabled to modify the timeout and should be enabled afterwards. However, I don't quite understand how to do this? Where can I disable and later enable Supervision? Is it through Codesys application or device menu? I don't find instructions clear.

Hi @TimvH, In the meantime, I did some experiments and could find a way to achieve similar result. I made some tests, removing the last card from the array, seeing the change on status.

Post by pedrorgd on SFC Exit Action during SFCReset Flag ^{CODESYS Forge talk (Post)}
I have an SFC POU with an SFCReset Flag that I use to restart it from the beginning. It works properly. During an Action Step I set one variable to TRUE and I reset it to FALSE during the Exit Action. My question is if this Exit Action will be activated -and the variable reset to FALSE- if I get out of the active step using the SFCReset Flag.

Post by dkugler on Beckhoff EL6652-0010 with Codesys ^{CODESYS Forge talk (Post)}
we use successful for many years the KEB MFI terminal for Profinet, EtherCAT, Ethernet/IP,... You'll need a EtherCAT Coupler as "head" from KEB, Kendrion or Berghof. It's all the same board inside: https://www.kebamerica.com/products/ethercat-bus-coupler/ Or the coupler with 16Di/Do integrated: https://www.kebamerica.com/products/ethercat-digital-io-module/ last year I got a EK1100 with EL6731 Profibus treminal runnig. But it was a lot of reverse engineering and thinkering in Codesys and TwinCAT to be done, to get it up, fulfilling my needs. Good luck!

Post by marks on Siemens G120X via Ethernet/IP ^{CODESYS Forge talk (Post)}
The goal is to control a Siemens G120X VFD via Ethernet/IP. The .eds is installed into the device repository. The VFD is added and is using the connection and assemblies from the eds. It appears to reach the VFD but fails to establish a connection. The status message is: Diag String: 'Adapter configured. Open all connections.' The PLC is a raspberry pi 4, running codesys target version 4.13.0.0. The development environment is CODESYS V3.5 SP21 + (64-bit). Anyone have experience with this combination? Alternately, where should I look next? Thank you, Mark

Post by mondinmr on Something of strange in the trace ^{CODESYS Forge talk (Post)}
I noticed something strange in the trace: one of the variables (specifically parts.servoFeeder.m_pathGen.m_acPos) is showing an absurd or unrealistic value—something around 4E+18. However, when I check the same variable in the watch window, it shows a normal and expected value (around 506). Do you know why there is this discrepancy between the trace and the watch? Could it be a bug in the trace tool? Thanks in advance!

Post by eschwellinger on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
I would recommend to ask Moxa for a newer version of Debian. Debian 9 ("Stretch") has reached its end of life and is no longer receiving security updates from the official Debian Security Team as of June 30, 2022. This means any systems still running Debian 9 are vulnerable to security risks and should be upgraded to a newer, supported version of Debian like Debian 10 ("Buster") or Debian 11 ("Bullseye").
