Post by schweizer on Position und Größe optimal anpassen (Container.Height - Visu.Height) funktioniert nicht. ^{CODESYS Forge talk (Post)}
Hello forum Does anyone have experience with optimally adjusting the position and size of the visualization elements? For us, the adjustment on the x-axis works in Codesys 3.5 SP20 with (Container.Width - Visu.Width). However, the y-axis is not affected with (Container.Height - Visu.Height). We implemented this according to the example from Codesys "Optimally adjust position and size" and had no success. Thank you very much for your help.

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.

Post by stribor on Passing properties as VAR_IN_OUT variables. ^{CODESYS Forge talk (Post)}
I am designing a custom slider object and i ran into a problem when i want to use properties with it. I can update the basic variables if i have a slider variable defined as VAR_IN_OUT, but it does not work with properties. How can i achieve same functionality that some basic objects have (for example basic Slider that comes withing the codesys libraries) such that i can pass both variables and properties to it and they can be modified within the object? I am using Codesys V3.5 SP20 Patch 5.

Post by felipemsgarcia on Edge Gateway online, but PLC is not online ^{CODESYS Forge talk (Post)}
Hello, I couldn't figure what/where the issue was, so I deleted everything from automation server and reinstalled the edge gateway and did the process again. It worked for about a month and then it stopped working again. It presents the same symptom, edge gateway is online but I can't connect to the PLC. Any idea of what could be the issue? Thank you!

Post by john-martin on Control SL Extension Package doubts ^{CODESYS Forge talk (Post)}
Hello everybody, I'm trying to understand the SL control extension package, more specifically, the external IODriver example, because C integration is very easy and I just made my first C component successfully. Ther External IODriver has no documentation and it's not clear how to proceed. Furthermore, there is no information on how to modify the device descriptor, which is necessary to import the device into the Codesys repository. Any advice ? Thank you in advance and best regards.

Post by dominggus on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I still have the same problem even when updating to CODESYS Recipes 4.3.0.0. My scenario: I'm trying to save/load an array of structs using the Visu: - Execute Command > "SaveRecipeAs" works properly - Execute Command > "LoadWriteRecipe" works not entirely: the structs of array[6] and array[7] should have been empty but were duplicates of array[4] and array[5]... the struct contains 26 variables and the array's length is 30.. Maybe there is a upper limit on recipe variable count?

"google and some other providers, prevent from using as iframe and similar injections." The goal I'm pursuing is to display remote graphical user interfaces from a local graphical user interface over a local network. thanks in advance, Riccardo

Post by miodusy on File transfer via visu and codesys automation server ^{CODESYS Forge talk (Post)}
I have a problem with the file transfer library. Namely, it does not work via the codesys server. (error 5; overtime, and visualization resets). They operate mostly in local chains. I tested different browsers and VPN from the router. It works everywhere, except through access from the codesys automation server. The client, having many machines under one account, prefers to keep it that way rather than use an individual VPN just to download a backup. Does anyone have an idea what the problem is? Sylwester M.

Post by andy-yemm on Assertion Failed ^{CODESYS Forge talk (Post)}
I had similar assertion failed error messages today. I am fairly new to Codesys. I tried using SFC for the first time, I usually use ST. Anyway I had errors in some of my transitions. I copied and pasted transition code and forgot to change the target of the code. I started getting lots of the assertion errors but now I have sorted out the problems and it compiles OK the assertion error messages seem to have stopped. There do not seem to be any other responses to your post, did you resolve your problem?

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 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 eschwellinger on License problem gateway ^{CODESYS Forge talk (Post)}
I just try to help. Anyway it is a big difference if a Store SL runtime or an oem plc and licence is used. These licenses need to be activated on plc side - so you have dependencies to the version (CODESYS and Runtime Version) Did you ever ask Epis out for this situation? They should know which license fit to their device. Even they should know if the device is capable for Softmotion and see the requiremnts in the CODESYS store: Runtime 4.9.0.0 - how should this work with Epis 3.5.16.x? Anyway refund is not a problem.

A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Post by gseidel on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
Hi kenth1973, MC_Phasing has been improved in recent versions. I would recommend to install the latest version of SoftMotion (4.20.1.0) and test whether the problem still exists, and if so, what the error identifier is. (Also check the PLC log in this case, it might contain additional information.) Setting the internal state of the FB is not recommended, it could lead to malfunction of the FB and unintended movements of the drive. Best regards, Georg
