Table Element Scroll Return

Post by cvrettacos-dse on Table Element Scroll Return ^{CODESYS Forge talk (Post)}
Hello, I would like to use swipe/pan gestures to scroll a table visualization element (CODESYS 3.5.21.10) on a DSE M810 display. The swipe / pan gesture control works fine, however, I cannot figure out how to reset / navigate to the top of the table again with code. I have tried the Scrolling begin variable, and the visu manager is setting it to FALSE right away but the table doesn't actually scroll back to top. If I check the “Scroll elements with scrollbar” box, then the Scrolling begin variable works perfectly, but now the swipe/pan scrolling no longer works and you have to use the scrollbar. Is it possible to do what I've described? Any assitence you can provide is appreciated. Thanks.

thank you eschwellinger. That one solved it for me. The password must have a length of at least 8 characters. The password must consist of at least 4 different characters. The password must contain lowercase letters. The password must contain uppercase letters. The password must contain digits. The password must contain special characters.

See the example below. You can insert key/value pairs as required At first the JSON string will be filled with: "{$"Key1$": $"Value0$", $"Key2$": [{$"Key3$": 1, $"Key4$": 2}]}" With xAdd, you can insert items, which will result in: "{$"Key1$": $"Value0$", $"Key2$": [{$"Key3$": 1, $"Key4$": 2},{$"Key3$": 3, $"Key4$": 4}]}" VAR factory : JSON.JSONDataFactory; eDataFactoryError : FBF.ERROR; pJsonData : POINTER TO JSON.JSONData := factory.Create(eError => eDataFactoryError); fb_JBuilder : JSON.JSONBuilder; wsValue : WSTRING; diRootIndex, diObjectIndex1, diObjectIndex2, diObjectIndex3 : DINT; iValue : INT; jsonArrayWriter : JSON.JSONByteArrayWriter; wsJsonData : WSTRING(1000); xFirst : BOOL := TRUE; xWrite: BOOL; xAdd: BOOL; END_VAR IF xFirst THEN fb_JBuilder.Reset(); fb_JBuilder(pJsonData := pJsonData, diRootObj => diRootIndex); wsValue := "Value0"; fb_JBuilder.SetKeyWithValue("Key1", wsValue, diParentIndex := diRootIndex); diObjectIndex1 := fb_JBuilder.SetKeyWithArray(wsKey := "Key2", diParentIndex := diRootIndex); diObjectIndex2 := fb_JBuilder.SetObject(diParentIndex := diObjectIndex1); iValue := 1; fb_JBuilder.SetKeyWithValue("Key3", iValue, diParentIndex := diObjectIndex2); iValue := 2; fb_JBuilder.SetKeyWithValue("Key4", iValue, diParentIndex := diObjectIndex2); xFirst := FALSE; xWrite := TRUE; END_IF IF xAdd THEN xAdd := FALSE; diObjectIndex3 := fb_JBuilder.SetObject(diParentIndex := diObjectIndex1); iValue := 3; fb_JBuilder.SetKeyWithValue("Key3", iValue, diParentIndex := diObjectIndex3); iValue := 4; fb_JBuilder.SetKeyWithValue("Key4", iValue, diParentIndex := diObjectIndex3); xWrite := TRUE; END_IF IF xWrite THEN xWrite := FALSE; jsonArrayWriter( xExecute := TRUE, wsLinebreak := "", pwData := ADR(wsJsonData), udiSize := SIZEOF(wsJsonData), jsonData := pJsonData^, xAsyncMode := FALSE ); END_IF IF jsonArrayWriter.xDone OR jsonArrayWriter.xError THEN jsonArrayWriter(xExecute := FALSE, pwData := ADR(wsJsonData), udiSize := SIZEOF(wsJsonData), jsonData := pJsonData^, xAsyncMode := FALSE); END_IF

Hi @TimvH, As discussed in our email contact, your example does not actually test/reproduce the bug I am describing: Adding to the JSON builder on later cycles works fine. Your example works because you do the following: 1. You finish the first cycle (xFirst) with adding an object to the array with 2 fields; 2. When the next cycle is triggered (xAdd), you immediately start with adding another object to that array. This works fine as the last thing you did before #2 was the addition of the array and an object to it. To reproduce the bug you should be doing the following instead, as I showed with the code I shared with my first post: 1. Create the array - save the index that is returned; 2. Add an item, either a primitive or an object, to the array; 3. Add an item outside the array (anything: a primitive, a new array, a nested object, etc); 4. Add another item to the array using the index you saved at #1. You will now see, as I shared in my initial post, that the second item is placed completely outside the root JSON object. This also happens to anything else you try to add after step #4: everything after this point will be added outside the root JSON object: the JSON is completely broken. Important to note is that this not only happens with arrays, but also with nested JSON objects. Once you add something outside of a nested JSON object, you can no longer add anything to that nested JSON object, as that causes the exact same bug. This also applies to arrays of objects, so if in your test you had tried adding a new key-value pair to the first nested object in your array after you created the second nested object, you would also run into this bug. It seems that the JSONByteArrayWriter (I haven't tested the other writers in the JSON Utilities SL library, so I don't know if they suffer from the same problem) simply does not handle any JSON fields that add brackets (so arrays with "[" & "]" and nested objects with "{" & "}") well, and closes them prematurely instead of checking if any later JSONElements in the JSONData's array belong to any of these bracketed fields. After reviewing the objects & functions of the JSON Utilities SL library, my guess is that either the JSONByteArrayWriter linearly goes through the array of JSONElements in the JSONData and only checks the diParentIndex of each JSONElement in direct ascending order, OR if it does use the JSONElement.GetChildren(); method, that this method is either broken and doesn't give all children correctly to the writer. Neither explains why everything completely breaks, and you cannot even add to the root JSON object anymore, however, so there is probably more than just that going wrong in the writer. To me, after a full week of testing and attempting workarounds, this seems like a bug in the library that needs to be fixed by Codesys, as I cannot see anything wrong in the JSONData constructed by the JSONBuilder - this seems purely a problem in the writer.

Post by wistaro on Hardware compatibility with Linux RealTime PLC ^{CODESYS Forge talk (Post)}
Hello, I am currently using Codesys Control RTE Softmotion V3 to control my servo-drives in CAN, EtherCAT and PROFINET IRT. I am using a PC with Windows 10 with the following boards: - PEAK-CAN PCIe board (for CAN and Softmotion); - Hilscher CifX with firmware 3.X and SysDrv3s driver (for PROFINET IRT); - Realteak standard NIC (for EtherCAT). I would like to switch to Linux (Debian), because this computer is old, slow, and outdated (Windows 11 is far from being compatible with this computer). Before doing this, I would like to be sure of the compatility between my 3 boards and Codesys Control Linux SL. Otherwize, I will stay on Windows 10 and use it in an isolated environnement. Thanks for your advices. Regards,

Post by charly29160 on WebVisu scaling regression in V3.5.22 P2: frame size jumps when switching visualizations ^{CODESYS Forge talk (Post)}
Environment: - CODESYS V3.5.22 Patch 2 - CODESYS Control for Raspberry Pi MC SL - WebVisu in browser Problem: When switching between visualizations using a Register element (Registerkarten), the displayed frame size jumps incorrectly after returning to a previously viewed visualization. This behavior was introduced in V3.5.22 Patch 2. The same project worked correctly in V3.5.21 Patch 4. WebVisu settings in V3.5.21 (working): - Scaling: Isotropisch - Automatisch ermittelte Clientgröße verwenden: active - All visualizations: Automatisch erkannte Visualisierungsgröße Workaround?

Hallo zusammen, ich habe ein hartnäckiges Problem mit der CODESYS-Visualisierung und hoffe auf eure Expertise. In meinem Projekt wird die Toolbox ("Werkzeuge") für die Visualisierung komplett leer angezeigt, es lassen sich also keine Basis-Elemente wie Rechtecke oder Kreise in die Zeichenfläche ziehen. Mein System: CODESYS V3.5 SP22 Patch 2 (64-bit) Device / Compiler-Version: 3.5.22.20 Das Kuriose:Das eigentliche Projekt läuft absolut einwandfrei. Mein Programmcode lässt sich ohne Probleme übersetzen, die SPS-Logik funktioniert fehlerfrei und auch die Simulation läuft einwandfrei durch. Nur das "Gesicht" des Projekts fehlt. Zwischendurch tauchte in den Meldungen der Fehler auf: Die Bibliothek '#System_VisuElems' konnte nicht aufgelöst werden. Was ich bereits zur Fehlerbehebung versucht habe: Installer-Check: Im CODESYS Installer geprüft, ob das Add-on "CODESYS Visualization" installiert ist (ist vorhanden und aktiv). Profil erzwungen: Im Visualisierungsmanager das Visualisierungsprofil manuell auf die aktuellste Version gesetzt. Gerät aktualisiert: Das Device im Projektbaum per Rechtsklick sauber auf die Version 3.5.22.20 hochgezogen. Clean Build: Mehrfach "Alles bereinigen" ausgeführt und neu übersetzt. Neues Projekt: Selbst wenn ich ein komplett neues Standardprojekt anlege, fehlen die Werkzeuge in der Visualisierung weiterhin. Hat jemand von euch eine Idee, woran das noch liegen könnte? Gibt es unter Windows eventuell einen versteckten Cache-Ordner für die Visualisierungs-Bibliotheken, den man manuell leeren muss? Für jeden Tipp wäre ich sehr dankbar! Viele Grüße
