Post by deeksha on RaspberryPi with CoDeSys throwing error ^{CODESYS Forge talk (Post)}
I am trying to access Raspberry pi on CoDeSys, but it throws an error says, "No connection to target: An established connection was aborted by the server." I am able to access Raspberry pi via MobXterm, but on CoDeSys, it throws error. Looking for help in resolving this error. Error snap is attached. IP address is scanned here successfully, but when I am trying to install Raspberry pi packet: 4.0.0.0, it throws this error.

Post by trprsmn on "Scan Network" doesn't find CR1140 device (ifm) ^{CODESYS Forge talk (Post)}
Hi, I'm watching an ifm tutorial on how to setup an industrial controller in CODESYS. I'm using an 'ecomatDisplay43inch_64bit) controller. CODESYS Gateway and PLC are both runngin (systray). However if I click "Scan Network" I can't find my controller. The only thing it finds is a "desktop" it seems (I'm using a Windows 10 on a Mac Book using VMWare, so maybe it has something to do with that?). How can I fix this? Thanks in advance!

hi, Does anyone know how to optimise the responisiveness of the web visualisation? When i open the webvisu on my laptop it is very responsive, no noticable lag. But when i open it on the HMI (web client) at the customer site there is a lag of +-500 when opening popups etc. The hmi used is: Phoenix Contact WP 6156-WHPS full hd Arm® Cortex®-A53, 1.6 GHz qt web browser The clients performance seems to be the problem, what can i do in my project to decrease the load for the client?

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 jddaigle on TargetVisu controls are incorrectly positioned ^{CODESYS Forge talk (Post)}
Hello, I'm trying to run TargetVisu on my Linux IPC, and while it does work, the controls are misaligned compared to my WebVisu. Both visualizations are full-screen on a Debian 12 VM with a resolution of 1280x768. The WebVisu is running in Firefox. Are there any configuration I should adjust to ensure the controls align properly between the two? Any guidance or troubleshooting tips would be greatly appreciated! Thank you.

Post by warrumungi on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
Hi Thanks, Manuel, for providing this solution and insight. I too had exactly the same problem as you did. While I did implement a custom filter, I'd also like to point out what jinlee mentioned above...I see no reference to VU.PublicVariables.Clients.Current anywhere?? In my case I only needed to show a dialog on a "master" client, not all the clients, so I filtered by IP address to do this.

Post by garrian on How to write multiple coils (Modbus FC15) ^{CODESYS Forge talk (Post)}
Thanks! As far as I can see, the client can only send words. And on the server side there are an array for each of the functions: bool for coil and discrete, word for holding and input registers. I assume I can use holding register, then use bit mapping on the words instead of coils. But I really want to use the FC15/coils.

Post by smartcoco on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
This seems to be because when creating 'OPC UA' with 'Communication Manager', the 'IdentifierType' of 'NodeId' cannot be configured as' String 'type. This issue is not an isolated case. For this issue, CODESYS seems to have not provided guidance to users on how to proceed. We can provide feedback on this issue in the 'My Question' section of the 'CODESYS Store' to make CODESYS take it seriously.

Post by trusty-squire on Codesys for raspberry pi 5 not working exactly ^{CODESYS Forge talk (Post)}
Not sure if you've resolved this yet, but the Codesys runtime user/password is different than the Linux user/password. You'll need the Linux user credentials when you log in over SSH (for example, to install the Codesys runtime). When you first log in to Codesys on the RaspPi you'll set up a Codesys user and password. If you lost those credentials, you could try uninstalling and then re-installing the Codesys runtime on the RaspPi so you can setup a new user/password.

Post by johnbomb on Ignore Dependencies When Loading Package? ^{CODESYS Forge talk (Post)}
I'm trying to load a .package into Codesys 3.5.21, but the package is intended to only work with Codesys 3.5.18.0 and is configured with dependencies on the specific versions of other packages included with 3.5.18.0, and 21 has newer versions so the package will not install. I would like to install the package anyway to try and get things working on a newer Codesys version, since for some reason the installer for .18 errors out and doesn't fully work in my environment, but .21 seems to work fine.

Hello, I have set up an OPC UA server following several guides, including this one: https://revolutionpi.com/documentation/tutorials/opc-ua-codesys-nodered/. The license for the runtime is installed on the device. However, I am unable to create a certificate for the OPC UA server in the security screen. I always get the error message: "The certificate has not been created by the device." Does anyone have an idea what might be causing this issue? Any help would be greatly appreciated!

Update: I still have no idea what was causing my issues, but it went away as soon as I identified that another device on the CAN was generating a Sync message at 16#7F. Changing this to be on 16#80 made the problem go away. I have no idea why this solves the problem and would love to hear from anyone who knows why these two things might be related.

Post by arwie on Use MC_Home without enabling the drive for homing method 35 ^{CODESYS Forge talk (Post)}
Is it possible to use MC_Home without enabling the drive (MC_Power)? On the drive the homing method 35 (Homing on current position) has to be executed. The drive has to stay disabled due to safety. This is explicitly allowed by the drive. Unfortunately MC_Home reports the error SMC_REGULATOR_OR_START_NOT_SET when executed. Are there other options to start homing, if not with MC_Home?

Thank you so much!

Post by eschwellinger on Licensing info not available. ^{CODESYS Forge talk (Post)}
yes and no ... if you run the license server on the host (to serve licenses to the docker instances / vplcs then there is no runtime which could check the licenses on the host. Therefore you need the CODESYS WBM to activate or check the licenes or you could use in CODESYS IDE the licensemanager ( not the one for the device licenses) but you have the the IP of the license server that he know where to search for the licenses ..tool options i guess to add it, will add a screenshot later.

Post by mputaggio on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.
