Are you sure when running as service, it is not reading configuration from C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS... ? Is the SRV user is set for the CODESYS services? 2 ways to fix it: Change the CODESYSControl.cfg in the installation directory (ProgramFiles/CODESYS...). Replace %APPDATA% with something fix. Modify the service configuration in windows service manager to run as a different user (ie bot as Local system account)

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 eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

Post by trusty-squire on Which database to use? ^{CODESYS Forge talk (Post)}
How large and how complex? It's tough to make a recommendation without additional details. The simplest thing is to just use data arrays (or even arrays of arrays). Not knowing your requirements, it might be sufficient and the simplest option is often the best. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_array.html You might also look into using Recipes? https://forge.codesys.com/prj/codesys-example/recipe-manageme/home/Home/ Some more complex options below. https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ https://store.codesys.com/en/mysql-library-sl.html

Wow! Thanks mr Strucc. Changed to service to run as local acc, and now log works! The service (run from local acc) is using this config: C:\Users\SRV\AppData\Roaming\CODESYS\CODESYSControlWinV3\C4DBB537\CODESYSControl.cfg The path you first mentioned (c:\Windows\System32\config\systemprofile\AppData\Roaming) has no CODESYS folder in it (Windows 11 24H2 b26100.3194). Thanks for your help :)

Post by trusty-squire on AXIS Rollover ^{CODESYS Forge talk (Post)}
In that case, the best thing to do might be to track the offset in a separate variable of your logic, then when you provide target positions, make your target position use the tracked offset as below: ActualTargetPosition := (TargetPosition + MyOffset) MOD 360; Although, upon further reflection, you'll still have the same cycle time issues. You might be able to break your code into multiple tasks to reduce the cycle time, or use an Event task to capture the offset position?

Post by trusty-squire on Ethernet/IP Scanner Exception ^{CODESYS Forge talk (Post)}
What is the task configuration? When you are online and look at the task monitor, what does it show? (Put a screenshot here). If the processor is overloaded you'll likely need to increase the cycle interval, disable the watchdog, or change to a cyclic task instead of interval based? Also, You might want to adjust your task priorities so they don't all have the same priority. Just a few thoughts, although looking at the task monitor would help in troubleshooting.

Here is the help sections for visual elements rectangle. https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_rectangle.html Under "Font Variable" there is "Color" which is a Dword, you can make a variable that changes colour within your code to the color needed. Note the format for the Dword variable is: colorVariable := 16#TTRRGGBB Where: TT = Transparency 00-FF RE = Red 00-FF GG = Green 00-FF BB = Blue 00-FF https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_animate_color.html

I need to be able to update (change) the interface of an IO-Link device at runtime. The reason is the connected sensor can be selected at runtime, and some sensors we use have a 2 byte IN interface, others have a 4 byte IN interface, others 16 byte IN, others 16 byte IN/OUT (see attached screenshot). Is it possible at all? When yes, which function should I use? Thank you!

Post by imdatatas on TO_STRING operator not working for IMPLICIT ENUM ^{CODESYS Forge talk (Post)}
Hi Everyone, It is a very useful feature to be able to obtain the enum value as a string with the TO_STRING operator by defining {attribute 'to_string'}. However, unfortunately the same function does not work for IMPLICIT ENUMs. I hope that {attribute 'to_string'} behavior can also work for Implicit Enumeration data types in one of the upcoming Codesys versions. https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_to_string.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_datatype_implicit_enumeration.html Best regards, Imdat

Bonjour, La librairy est SYSMEM en Codesys v3.5. Pour accéder à la fonction : SysMem.SysMemSet. Il y a plein d'autres fonctions intéressantes : SysMemSwap, SysMemMove, SysmemCpy, ... Cela évite de créer des Boucles et permet de bien utiliser ADR() et SIZEOF() Il existe aussi une librairie CAA Memory qui mérite intérêt; Par exemple MEM.MemFill pour remplir un tableau d'octets. Bons développments! Il suffit d'ajouter ces bibliothèques dans le gestionnaire de bibliothèque pour les utiliser. JM

For example, when SMC_TRAFO_5Axes is used, parameters B and C can be resolved by the transformer. However, parameter A cannot be resolved. Only SMC_Interpolator displays the value of parameter A in the SMC_Interpolator => piSetPosition.dA output. Should I drive this axis with SoftMotion commands (MC_MoveAbsolute etc.)?
