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.

Hello @florian, Could you please help with how to set an array value? I've been trying to use the with the setKeyWithArray method which creates the key with an empty array value. But I have been unable to set items in this array? objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindexx); //iValue: array[0..n] of int; Best regards

okay but will this pass the array by copying it or it will be a reference to original array only.

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?

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

You cannot create an array of Programs. Create a Function Block for this purpose instead of a program. You can create an array of FB instances and call each instance in a loop.

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.

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?

I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

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]

Hello! I use CheckBounds (POUs for Implicit Checks). But I have a problem. I use an array as an VAR_IN_OUT of Function Block. If I try to monitor the array of variable length ([* ]), its does't work. The CheckBounds POU isn't called. If I use the array of fixed lenght ([lower..upper]), the CheckBounds POU is called. Why?

We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND
or OR
.
