Did you find a solution for this? I am seeing the same errors.

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
maybe this would be a better approach, then you don't have to pass the constant at all. FUNCTION fun : INT VAR_IN_OUT arr: ARRAY[*] OF INT; END_VAR VAR lower: DINT; upper: DINT; END_VAR lower:= LOWER_BOUND(arr, 1); upper:= UPPER_BOUND(arr, 1); see here as well https://help.codesys.com/api-content/2/codesys/3.5.12.0/en/_cds_datatype_array/

Post by shamcke on Array with generic constant as persistent variable ^{CODESYS Forge talk (Post)}
Hello, I have written a function block that uses a generic constant for the upper bound of an array. I wanted to have this array in the persistent memory area, thus I constructed my FB as follows: FUNCTION_BLOCK FbWithGenericArrayLength VAR_GENERIC CONSTANT uiArrayLength : UINT := 10; END_VAR VAR PERSISTENT arr : ARRAY[1..uiArrayLength] OF INT; END_VAR In my PLC_PRG I declare an instance of said FB PROGRAM PLC_PRG VAR myFb : FbWithGenericArrayLength<10>; END_VAR This compiles just fine. When I let CODESYS fill my persistent list, it adds duplicate entries {attribute 'qualified_only'} VAR_GLOBAL PERSISTENT RETAIN // Generated instance path of persistent variable PLC_PRG.myFb.arr: ARRAY [1..uiArrayLength] OF INT; // Generated instance path of persistent variable PLC_PRG.myFb.arr: ARRAY [1..uiArrayLength] OF INT; END_VAR so I manually delete the duplicate. When i now compile, I get errors ------ Build started: Application: Device.Sim.Device.Application ------- Typify code... [ERROR] Sandbox_FW31: PersistentVars [Device: PLC Logic: Application](Line 4): C0161: Border 'uiArrayLength' of array is no constant value [ERROR] Sandbox_FW31: PersistentVars [Device: PLC Logic: Application](Line 4): Type of mapped variable is not equal to original type Compile complete -- 2 errors, 0 warnings Build complete -- 2 errors, 0 warnings : No download possible Is is simply not possible to use a generic constant for the persistent array? Thanks in advance. Edit: It seems I can manually replace the uiArrayLength in the persisten list by the value 10 I used as the generic constant for this particular instance.

Post by jorenbeyl on library inside library ^{CODESYS Forge talk (Post)}
I am currently developing a library that contains real‑time data. To handle this real‑time data, I am using additional libraries called SysTime and SysTypes Interfaces. When I compile my library on its own, no errors occur. However, when I use this library in a project and compile the project, I get an error indicating that the SysTime data type is not recognized. This happens even though the SysTime library is visible as a dependency under my library. Does anyone know how to correctly include a library within another library so that the project recognizes the sub‑library without causing compilation errors?

Post by timvh on library inside library ^{CODESYS Forge talk (Post)}
1) it should be possible to access the type SysTime in the project as A_Lib.SysTime. 2) you could add the SysTimeCore library to the library manager of your library (POU Pool). This might seem as a double library, but because of the placeholder resolution only one will be used. Then, in your library manager of your library, select the SysTimeCore library, right-click, select "Properties" and enable the option "Publish all IEC symbols ...." For more information about library development, you could follow our advanced training course in Ridderkerk. The next is scheduled for 24 and 25 June 2026 https://www.extendsmartcoding.nl/codesys-training/

Hey there, is there a way to extract any data out of a .library or a .compiled-library file? Do you have any tools or a description of the binary or something like this to get for example the referenced libraries of a *.library file or any other stuff? Thx in advance M.

Post by wedahitha on Could not open library 'SysSocket23, ^{CODESYS Forge talk (Post)}
Hi there, I am trying to open a codesys project done by someone else and Once I install all the libraries I get this error [ERROR] : Library Manager [PROJECT 01: PLC Logic: Application]: Could not open library 'SysSocket23, * (System)'. (Reason: The library 'SysSocket23, * (System)' has not been installed to the system.) SysSocket23 is a standard library and I also tried using the same OSCAT library which was from the original computer that made this code. Using CODESYS V3.5 SP18 Patch 2 Please help me how to solve this problem.
