Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Post by rickj on Defining local variables that can be independent with several users. ^{CODESYS Forge talk (Post)}
You need to create an array with one element for each possible user. I usually define these arrays in the root screen. FrameIndex : Array [0..MaxUsers] OF INT; Then use the global CurrentClientId (defined by one of the VISU libraries) to index the array element used to select the frame. FrameIndex[CurrentClientId]

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by janber on REFERENCE TO in an array ^{CODESYS Forge talk (Post)}
Hi all, in the online help it written, that array of reference to data type is not possible. Ok... but if I create array of struct of reference to - everything works fine - please see the screenshots: and it works this way OK. Is it intention or error in compiler 3.5.18.20 and we should avoid it? Thanks a lot, Jan.

Post by ph0010421 on How to manage variable types larger than 64 bits - Ethernet/IP ^{CODESYS Forge talk (Post)}
So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

Post by paro on OPCUA array max length? ^{CODESYS Forge talk (Post)}
I think the amount of data is already relatively high and maybe it has something to do with that? Maybe also the CPU load of your device? an array with string(5000)? and have you tested with how many array elements it still works?

Post by timvh on displaying all incoming CAN bus messages ^{CODESYS Forge talk (Post)}
Create a (global) array of Messages: aMessage : ARRAY[0..NR_OF_MESSAGES-1] OF CAN.RxMESSAGE; Then add each received message to the array. IF UserVarGlobal.g_countMsg_RPMset < NR_OF_MESSAGES THEN aMessage[UserVarGlobal.g_countMsg_RPMset] := Message; UserVarGlobal.g_countMsg_RPMset := UserVarGlobal.g_countMsg_RPMset + 1; END_IF

Post by ihatemaryfisher on Sorting array of any-sized structure ^{CODESYS Forge talk (Post)}
With that I could make an array of varying size, but would still have to define the array type in the function's declaration VAR_IN_OUT stArray: array [*..*] of <pre-defined data type> END_VAR I wanted a function that could take an array of any type (e.g., a structured VAR) as an input. That way I could call it in multiple POUs to handle different arrays structures.

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?

Post by abinvest579 on COP instruction ^{CODESYS Forge talk (Post)}
Hi All, I have hands on rockwell software like rslogix 5000 and studio 5000. Currently started working on codesys i want to know is there any COP instruction with similar functionality in codesys like rockwell. I want to use it to split REAL into 2 INT,DINT to 2 INT also reverse 2 INT into DINT and 2 INT into REAL. Thanks in advance
