Post by drml on How to implement an interface (IElement)? ^{CODESYS Forge} ^talk ^(Post)
I'm struggling with the implementation of the IElement interface (in the ElementCollections library), which I will use to create a SortedList. I created a class (FB) "Device" that implements this interface and that has a "Priority" property that I want to use in order to compare the devices in my implementation of the ElementCompareTo method. Unfortunately, the IElement.ElementCompareTo method needs an IElement as an input, which doesn't know about the "Priority" property of "Device". I tried to define the input itfElement as a Device, but then it doesn't want to compile, because the type in the implementation doesn't match the interface.

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.

Reading between the lines of what you did not specify, it therefore seems to appear that in the programme, at the end of the movement order, there is an order to remove power and switch off the pulse modulation. if this is the case, it is obvious that the motor then remains free. If the position is to be maintained at the end of the movement, the motor current modulator, which on the PLC side is controlled via the MC_Power method, must not be interrupted. Another possibility is that in the motor drive settings, the standstill torque current is set very low or zero and without position monitoring. You have to check this via the servo motor drive.

Post by bernhardw on Probleme mit MC_HALT_SML und MC_STOP_SML ^{CODESYS Forge} ^talk ^(Post)
Hallo … ich verwende: SoftMotionLight im Positions-Mode Ethercat-Bus Servoverstärker: Metronix BL4104-C . MC_HALT_SML funktioniert nicht zuverlässig (Achse fährt manchmal zu weit oder bis zum Softwareschalter) Ich habe festgestellt, dass intern beim Aufruf von Positions- auf Velocity-Mode umgeschaltet wird - und dann wird wahrscheinlich intern auf Drehzahl 0 abgeregelt. Kennt jemand dieses Problem? – der Wechsel der Betriebsart ja ist nicht verzögerungsfrei! MC_STOP_SML Der Baustein hat keinen Eingangsparameter "Deceleration" Die Achse stoppt und bleibt im Positions-Mode. Aber die Verzögerung ist nicht wie beschrieben: nicht "Objekt 6085h: quick_stop_deceleration" - sondern "Objekt 6084h: profile_deceleration" - aus zuvor aufgerufenem MC_MOVE_ABSOLUTE_SML Ich wäre dankbar für jeden Hinweis Gruß Bernhard

@gepert, When you say "I do not turn off power", are you saying you don't power off the drive, or you don't turn of the MC_POWER function block? I read your statement as you don't kill actual electrical power. MC_POWER should stay enabled. @Gustavo, not related to problem at all, but when you say 1.6 Nm is only enough torque to unscrew a loose bottle cap, I think that's a bit low. A quick mental math I use is 1 Nm is almost the same force as 1kG applied to a 10cm wrench. So 1.6kG applied to a 10cm wrench is still not a huge force, but more than enough to be felt if trying to turn the shaft by hand.

Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge} ^talk ^(Post)
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by jp23 on Unable to Connect to Modbus RTU Device ^{CODESYS Forge} ^talk ^(Post)
Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Post by otbeka on CmpCrypto CryptoGenerateHash Not Outputting ^{CODESYS Forge} ^talk ^(Post)
Unfortunately I noticed that, and tried: * using CryptoGeteAlgorithmByID within the function call * inputting the raw byte pointer as a testByte * instantiating the _hHash handle within the function body * using a different cryptoID or the raw DINT values from the RtsCryptoID DUT ... to no avail. The pReturn value is also set to 0, which would indicate that it is OK, right? This is odd given that the function is the same within the CryptoDemo example project here, just with a newer version. Is it possible that there is something wrong with the way my bytestring is being set up? I use the following DUTs here: TYPE MESSAGE : STRING(255); END_TYPE TYPE HASH_CODE : ARRAY[0..19] OF BYTE; END_TYPE

Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge} ^talk ^(Post)
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by andrebrandt on FB string and naming ^{CODESYS Forge} ^talk ^(Post)
Hi Tim. Not quite correct. What i'd like, is when you place the FB in prog, i choose a block NTC10k, and name this RT401. What i'm trying to do, is to get the name RT401 automaticly into the FB, so i can put this into the string i pass in a struct. So in var in POU, i saw this a place i could do this, RT401: NTC10k(Tag:='RT401'), but i can't get this to work. I shurly must have had something like this in FB: FUNCTION_BLOCK NTC10k String TAG But it's here where I'm stuck...

Post by dakmueller on Digital Input nachrüsten ohne Variablen umbenennen. ^{CODESYS Forge} ^talk ^(Post)
Hallo zusammen, ich habe ein Problem mit einer Anlage. Dort müsste eine Digital Input Karte(XNE-8DI-24VDC-P) nachgerüstet werden. Das Problem ist, dass wenn ich die Karte über die Steuerungkonfiguration einbinde, die Karte direkt hinter den Eingangskarten und vor den Analogkarten positioniert wird. Dadurch müsste ich die Variablen der Analogkarten ändern, die hinter der Digitalen Eingangskarten sind. Das wäre Mega Aufwand. Gibt es eine andere Möglichkeit? z.B hinter die Analogkarten zu Adressieren? Z.Zt. sieht es so aus: %IB0 %IB1 %IW2 %IW4 %IW6 Zwischen %IB1 und %IW2 soll die neue Karte. Dadurch wird %IW2 zu %IW4. Dadurch müssen alle Variablen nach %IW2 geändert werden. Vielleicht kann mir jemand helfen. Danke Dennis

Bonjour, J'essaie de tester cette application : Je suis bloqué sur les 2 chapitres suivants : Pour la toute première configuration de communication : ajout de la passerelle Spécification du canal de communication En suivant le tutoriel, j'ai bien le point vert disant que la passerelle est OK en localhost sur mon PC Ensuite, en choisissant le chemin vers le controleur et en faisant un scan réseau à partir de cette boite de dialogue, ça ne trouve rien et je finis par avoir un message d'erreur disant que la passerelle n'est pas configuré... De plus, Je ne comprends pas pourquoi il faut passer par une pseudo connexion alors que toute l'appli et donc la simu est sur mon PC... Merci pour vos lumières Bonne soirée Désolé, ça plante quand je joins un fichier

Post by yoeri on Refresh visulization realtime ^{CODESYS Forge} ^talk ^(Post)
Hi everyone, I need some help with displaying an image (test.png) on my device. Initially, showing the image is straightforward. However, I want to be able to update the image dynamically. My goal is to send updated files via FTP to the device, and have the display automatically show the latest version of the image. All images will be sent with the same name (e.g., test.png). Currently, I can see the updated image after sending it via FTP and performing a warm restart, but I'd like to achieve this in runtime, without having to restart the display or application. Does anyone have suggestions on how to implement this? Thanks in advance!

Post by bertcom on Converting each character to a string into ASCII ^{CODESYS Forge} ^talk ^(Post)
Good afternoon, I have a project where i need to split a string and send it in ascii code to an Domino Printer. Concept: i get an String from an Zebra scanner looking like this : " R002043;5410761402862;Oil Plus 2C Comp.A - Gris Belge;1286193824;" To start is the ";" the seperator. i found some functions to delete the ";" in a string. this is okay but now i want to convert each digit in the string into ascii like this: R=82 0=48 0=48 2=50 0=48 ... This because the printer wants to receive a string like this: <esc>OQ001TE 82 48 48 50 48 ...<eot></eot></esc> Anyone who can help me with setting me on the right track with some advice?

Post by pistola on Visualization Size - Set Layout ^{CODESYS Forge} ^talk ^(Post)
I feel like this is a setting issue and I can't seem to find the right setting. I have a new project that I'm looking to add visualizations to however when I select my template size (1280 x 800) I make sure in my properties under the visualization tab, I have "Use specified visualization size" selected and my width set at 1280 and height set at 800. Now within my visualization editor I can't see to get the size outside of my template to grey out. I've attached a PDF showing what I'd like the visualization editor to look like and what mine currently looks like. Any help would be greatly appreciated.

Post by manuknecht on Maximum dynamic limits of MC_MoveLinearAbsolute and MC_MoveLinearRelative ^{CODESYS Forge} ^talk ^(Post)
Hello all I use an axis group with two linear axes in a kinematic system. Using MC_MoveLinearAbsolute and MC_MoveLinearRelative, I am trying to realise dynamic movements (set velocity: 1 m/s, set acceleration: 30 m/s^2) with the highest possible jerk, as I want to compare this with a movement with a trapezoidal velocity profile. However, my measurements show that the axes accelerate with a maximum jerk of approx. 800 m/s^3, even if the value in the function block was set to 10,000 m/s^3. I have already increased the dynamic limits of the two axes accordingly (Velocity: 5000 u/s, Acc-/Deceleration: 250'000 u/s^2, Jerk: 100'000'000 u/s^3, where 1 u = 1 mm), but this had no effect. I have checked the input parameters of the function blocks and the VelFactor, AccFactor and JerkFactor factors are all set to the maximum (value 1). Reducing the cycle time has resulted in a higher jerk, but as we are already working with a cycle time of 1 ms, there is nothing more that can be done here. The axes themselves are still a long way from drawing the maximum current, which is why I assume that this should not be a problem either. Are there other factors or parameters that influence the dynamic limits and therefore allow faster movements? The PLC I am using is a Raspberry Pi 4 and Codesys V3.5 SP20 with all libraries up to date. Thanks in advance Manuel

Post by thommy54 on CODESYSControl_User cfg richtig konfigurieren ^{CODESYS Forge} ^talk ^(Post)
Hallo, nach Erwerb eines neueren Raspberry pi 4 (V1.5) musste ich zwangsläufig von Codesys 3.5.16 hochwechseln - ich habe auf 3.5.20.1 geupdated. Da schlugen mir plötzlich ne Menge Einschränkungen entgegen, deren Behebung einige Zeit dauerte. Eine davon ist, das ein SysFile.SysFileOpen nicht mehr funktioniert. Ich habe das Problem mit Einträgen in der /etc/CODESYSControl.cfg behoben: [SysFile] FilePath.1=/etc/, 3S.dat IecFilePath.1=/proc/, cpuinfo IecFilePath.2=/proc/, iomem PlaceholderFilePath.1=/sys/devices/w1_bus_master1, $OneWire$ PlcLogicPrefix=1 ; ; ---------------------- ; selbst eingefügt PlaceholderFilePath.2=/home/root, $my_home_root$ PlaceholderFilePath.3=/etc/init.d, $my_conf$ PlaceholderFilePath.4=/var/lib/mpd, $my_music$ PlaceholderFilePath.5=/root/Rasp_SPS_Filesystem, $my_Rasp$ Ob die Einträge sich etwas überlappen, kann mir gern jemand sagen, das ist aber nicht das Problem. Ich habe bei den vielen Versuchen, das Teil zum Laufen zu bringen, bemerkt, daß die Einträge auch ganz schnell mal verschwinden. Das ist ja auch so beschrieben, wenn die nächste Version kommt, sind meine Einträge weg. Da ich ähnliche Probleme mit dem Funktionieren von "SysProcessExecuteCommand2()" hatte, die ich ebenfalls mit Einträgen in die /etc/CODESYSControl.cfg hätte beheben können, habe ich gelesen, das man "private" Einträge lieber in die Datei /etc/CODESYSControl_User.cfg machen soll. Gesagt getan und "SysProcessExecuteCommand2()" lief: [SysProcess] Command=AllowAll Command.0=shutdown Aber auch irgendwo stand, das so ein Beteichner wie [SysFile] oder [SysProcess] nur einmal in den beiden Files /etc/CODESYSControl.cfg oder(!) /etc/CODESYSControl_User.cfg vorkommen darf. Das ist nun die eigentliche Frage! Ist das so ? Bei [SysProcess] ist das kein Problem, das gibt es in /etc/CODESYSControl.cfg nicht. Aber bei [SysFile] sieht das anders aus. Da sind 5 Zeilen schon in /etc/CODESYSControl.cfg drin. Würde ich diese in die User-Datei rüberschieben, könnte beim nächsten Update was fehlen oder, oder... Lasse ich es so wie es ist, sind meine Einträge beim Update weg - das sollte ja verhindert werden. Kann da jemand genaue Auskunft geben ?? Vielen Dank Thomas

Post by thommy54 on Raspi-Cam: CameraStream.project nicht zum Laufen zu bringen ^{CODESYS Forge} ^talk ^(Post)
Hallo, Ich bringe das CameraStream.project nicht zum Laufen. Ich sehe die Ursache darin, das das Beispielprogramm sehr sparsam mit Programm-Kommentaren umgeht (von der Hilfe gar nicht zu reden). Ich habe beide Varianten bei der zu ändernden Zielvariable getestet: //copy video.htm to the webserver; //the location of the webserver depends on the used Apache version as mentioned in online help hDirHtmlTest:=SysDirOpen( szDir:='/var/www', pDirInfo:= ADR(dirInfo), diMaxDirEntry:=iMaxDirEntry, szDirEntry:=szDirEntry, pResult:=ADR(iDirHtmlError)); IF (iDirHtmlError = 0) THEN SysDirClose(hDir:=hDirHtmlTest); SysFileCopy('/var/www/video.htm', '$$PlcLogic$$/Application/video.htm', ADR(dwCopySize)); ELSE .... als auch hDirHtmlTest:=SysDirOpen( szDir:='/var/www/html', pDirInfo:= ADR(dirInfo), diMaxDirEntry:=iMaxDirEntry, szDirEntry:=szDirEntry, pResult:=ADR(iDirHtmlError)); IF (iDirHtmlError = 0) THEN SysDirClose(hDir:=hDirHtmlTest); SysFileCopy('/var/www/html/video.htm', '$$PlcLogic$$/Application/video.htm', ADR(dwCopySize)); ELSE .... Die Url-Streams habe ich gelassen wie sie vorgegeben waren: urlStream := CONCAT('http://', CONCAT(sIPAddress, '/video.htm')); urlPicture := CONCAT('http://', CONCAT(sIPAddress, '/cam_pic.php')); In der Webvisu im Browser komme ich maximal dahin wie im Screeshot Video_Visu_1 zu sehen. Also scheint der Link zu video.htm zu klappen. Das der zu cam_pic.php nicht klappt, wundert mich nicht, denn es existiert nicht und wird auch nicht evtl. am rechten Ort angelegt. Ich bin mir vollkommen im Unklaren: muss da was auf dem Raspberry Pi im Hintergrund laufen , z.B. raspivid . Welcher Programmteil bedient die Cam ? Ich erkenne auch nicht, wo ein einzelnes picture entstehen soll. Wäre dankbar, wenn ich hier etwas Hilfe bekommen könnte. Evtl. gibt es Probleme mit der von mir verwendeten Codesys-Version 3.5.20.1 ? Ich benutze einen Raspberry 4 Rev.1.2. Grüße Thomas
