Post by leon78 on Codesys 3.5 SP17 Patch 2 CheckBounds (POUs for Implicit Checks) ^{CODESYS Forge talk (Post)}
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?

Post by alexgooi on Init Array input on a method ^{CODESYS Forge talk (Post)}
Dear Forum, I would like to initialize an array input on a method. When I do this, I get the following error: "The type of ARRAY [1..2] OF BOOL cannot have a default value in this context." I attached a picture for more clarity. Is this simply not possible or is there a different way of tackling this problem? Thank you in advance

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 szotyi on Array of Program ^{CODESYS Forge talk (Post)}
Hi! What is the proper and the easiest way to call programs through looping of array of programs, or pointer of program? instead of calling the programs one by one: prog1(inputX: 11); prog2(inputY: 12); prog3(inputZ: 13); similar like: VAR programsToCall : ARRAY [1..3] OF PROGRAM; END_VAR programsToCall[1] := prog1(inputX: 11); programsToCall[2] := prog2(inputY: 12); programsToCall[3] := prog3(inputZ: 13); FOR i := 1 TO 3 DO programsToCall[i] (); END_FOR Thanks.

Post by hazarath on How extract JSONElement containing Array data ^{CODESYS Forge talk (Post)}
I want to extract each element of an Array. Can someone help me with this. When I use JSONElementToString (part of JSON Utilities SL), I am seeing output as "ARRAY" instead of actual data. Here is the JSON content that I want to read : { "value1Unit": { "units": "M" }, "data": { "stepSize": 300.23, "points": [6,8] } } I would like to read each item of the element "points" i.e. 6 and 8. Here is the code I used, // Reading the content as JSON reader ( xExecute := execute , pwData := ADR ( converted_value ), jsonData := jsonDataStorage ); // Get the JSON Element jsonDataStorage.FindFirstValueByKey( wsKey := fidKeyVar, diStartIndex := searchElem, jsonElement => jsonElement ); JSON.JSONElementToString ( element := jsonElement , wsResult := valueWstring ); The content of the output of valueWstring is shown as "ARRAY" instead of the array items i.e. 6 and 8 Please can someone help me.

Post by rjonker on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

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.

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
