Post by jeffg on License issue with visu tags ^{CODESYS Forge talk (Post)}
I seem to be having a problem with the license on ver 3.5.19 patch 5 The runtime keeps going into demo mode but it wont tell me the reason I looked at the license software metrics and the visu doesn't appear to be working I attached screen shots of the metrics screen and the license dongle that is plugged in to the windows PC Anyone have any ideas on how to fix this

Post by mandeepahujaifm on Ethernet/IP 4.6.0 causing exceptions? ^{CODESYS Forge talk (Post)}
I have experienced the same with one of our customers after updating EIP Scanner to 4.6.0.0 and really baffled by it. The core dump simply shows error with ENIPScanner I/O task and on analyzing it says no source code available for 4.6.0.0. Contemplating to go back to 4.5.1 but 4.6.0.0 has some really nice fixes. I guess it don't matter if it crashes anways. Please keep us posted if you find anything.

Post by mubeta on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
This is normal and correct since in CoDeSys static addressing of variables uses the IEC method. A LONG tag has the size of 8 bytes, so %ML0 coincides with %MB0 ... %MB7; %ML1000 with %MB8000 ... %MB8007. (Similar reason for word and other formats). Also the reason the compiler won't let you map the structure to a %MW depends on the fact that the individual base elements are manipulated to 64 bits regardless of the smaller size. That said, it makes me strange that you cannot write a parser without making use of static memory allocation.

hello edwin i have did the same and i could connect the opc-ua server but i dont see anything in the resources tree, in the application i linked my variables to the symbol configuration but i dont see that in the uaexpert. if i use the same application with a non linux system i can get those variables values and see the complete tree structure. What could be the problem ?

Post by taqamert on IFM-Sensor ADC READ ^{CODESYS Forge talk (Post)}
I have a pressure sensor that measures 0-600 bar and outputs a 0-5V signal, but my PLC reads analog inputs in the 0-10V range and displays a value of 1024 when 10V is applied. In this case, when the sensor outputs 5V at 600 bar, the PLC shows a value of 512. My working range is 0-350 bar, which means the PLC only uses 298 bits in this range, significantly reducing the resolution. What can I do to achieve better resolution within the 0-350 bar range?

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 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.

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.

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.
