Hi Georg, thanks for your time. What is the value of D_ANGLE_TOL? It is set to 0.01. Do you need the assignment bAbort := NOT bDecoder? Does it help to leave it out? This seems to make no difference. Any errors (e.g. SMC_SmoothPath.Error/ErrorID) or PLC log messages? No errors or log messages. What if you comment out SMC_SmoothMerge and SMC_LimtiDynamics, is corner smoothing still not working? Indeed. Is bDecode written from a different task (e.g. visu)? Then I would recommend to assign to a local variable (bDecodeLocal := bDecode) and use that for all FBs. Otherwise, FBs might see different values of bDecode in a single cycle, which will cause problems. It is a local variable, written from a state machine inside this program. But there is new information: During some trial and error, I tried skipping "stage 2: merge short linear segments" (SMC_SmoothMerge). And suddenly it rounds the corners, see attached image. Looking a bit closer, I noticed that (with the original program) after a download (cold start?), it in fact did round the corners, but only once. Ever next cycle in which the NC program was executed, the corners where not rounded. Not sure if there is any relation, but SMC_SmoothMerge is also the only FB which has no bAbort input. Perhaps I need to reset it (or any buffers) by other means?

Guten Morgen, wie der Titel verrät soll es hier um das Ausrollen der CODESYS Runtime auf einem Raspberry Pi gehen. Ob ein klassischer Raspberry Pi aus dem Consumer-Bereich oder ein Compute-Modul spielt in dem Fall keine Rolle. Ich möchte nur anderen Nutzern Hilfestellung geben, die vielleicht ein vergleichbares Problem haben wie ich: Auf Raspberry Pi lief bei mir eine Anwendung, die mit Lizenzen auf einem CODESYS-Dongle lizenziert waren (Multicore-Support und Softmotion). Nach einem Hardware-Defekt habe ich meinen Rasperry Pi gegen eine robustere Lösung getauscht. Ich wollte auf der neuen Hardware die Runtime ausrollen und habe ständig den Fehler gezeigt bekommen, dass die Target- oder Zielsystem-ID nicht stimmt. Für den Raspberry Pi gibt es ja drei verschiedene Optionen der Runtime: 32bit Singlecore (armv6l) 32bit Multicore (armv7l) 64bit Multicore (aarch64) Entscheidend dafür, ob die 32 oder 64 Bit Runtime benötigt wird ist das auf der dem Raspberry Pi installierte Betriebssystem. In meinem Fall hatte ich durch die neue Hardware auch ein aktuellen Betriebsystem-Image aufgespielt, weshalb sich da der Umstieg von 32 auf 64Bit eingeschlichen hatte. In der Entwicklungsumgebung kann über Tools -> Control SL ausrollen das Fenster geöffnet werden, um die richtige Laufzeitumgebung auf dem Steuerungsrechner zu installieren. Bei kleinen Bildschirmen (bei mir ein 15" Laptop) kann der rechte Bereich "abgeschnitten" und das Dropdown-Menü als solches nicht auf den ersten Blick erkennbar sein. Mein Fehler war, dass ich den Scrollbalken nicht gesehen habe! (Bild im Anhang mit freundlicher Genehmigung von Herrn Heberle vom CoDeSys-Support) Nach dem auswählen der jeweils passenden Version kann die Runtime installiert und das Programm wieder geladen werden. Die Lizenzen sind bei mir wieder korrekt erkannt worden und alles läuft wie vorher (nur mit neuer Hardware). Vielen Dank an der Stelle noch mal an die schnelle Hilfe vom Support. Das hat wirklich top funktioniert.

Yep sure, though now that i think of it, its a pi 4. My bad. The whole ordeal was necessary to use the VGA666 adapter. That needs the old graphical system and GPIO directly on the CPU. Edit: Putty on the virtual development machine connects fine. But i did change the login/pw. The account is still a sudo'er so that should be all right. Edit2: Sorry i get a "Comment rate limit exceeded" from the forum. Then i'll add it as edit here. So i have tried the stock raspberry pi image on a different pi5 (truly 5 this time). Packages updated. Standard password. Same symptoms, no runtime deployed and long hang time. Versions of this pi: pi@raspberrypi:~ $ uname -a Linux raspberrypi 6.12.25+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.25-1+rpt1 (2025-04-30) aarch64 GNU/Linux pi@raspberrypi:~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 12 (bookworm) Release: 12 Codename: bookworm pi@raspberrypi:~ $ apt list --installed | grep openssh-server openssh-server/stable,now 1:9.2p1-2+deb12u6 arm64 [installed,automatic] Attached is the Device information and error text that Codesys comes up with. Edit 3 (Comment rate limit, otherwise it would be a new post) Now i have tried booting an older native Windows 10 machine (no virtualization), and it just works as expected. I have now a raspberry pi 4 and raspberry pi 5 with version 4.16.0.0 of the control application. Windows 10 native: build 19045 (same as virtualised Win 10), same .NET version, same CODESYS version. It seems that running CODESYS virtualized somehow messes with the deployment?

Hallo Edwin, ich bräuchte mal eine schnelle Hilfe. ich testete einen zweiten Raspberry Pi 4 mit meinem Lizenzdongle eines laufenden Raspberry. Der 2. Raspberry ist als Redundanzlösung bei einem Crash gedacht. DIe Schwierigkeiten begannen, als ich mit dem Raspberry 4 V1.5 nicht mehr mit SP16 weiterarbeiten konnte. Ich updatede auf SP20.1. und die Schwerstarbeit begann. Das Image wurde rübergeschoben und alles auf dem zweiten Rechner soweit zum Laufen gebracht. Der Dongle wurde ebenfalls am 2. Rechner eingesteckt. Ob er überhaupt wirkte, kann ich nicht sagen, da für diesen Testfall Codesys so oft rauf und runter gefahren wurde, das die 2h-Grenze kaum erreicht wurde. Problem: Beim Zurückstecken des Dongles in den ursprücnglichen Rechner ist alles an Lizenzen weg. Der Lizenzmanager hat keinen Container mehr und der Befehl "lsusb" bringt nichts zurück. ich war der Meinung, das der Dongle genau für diesen Zweck gedacht war - die Lizenz von einem Rechner zum anderen mitzunehmen. Liege ich da falsch ? Wie komme ich nun wieder zu einem funktionfähigen Dongle ?? Weitere Versuche unternahm ich mit dem Wiederherstellen des Dongels. Dabei steckte ich ihn in meinen PC (Workstation) und siehe da, es werden noch 3 von ehemals (2020) 6 Lizenzzeilen angezeigt: (siehe Bild Problem_Lizenzen_Raspberry.jpg) Dann versuchte ich das Wiederherstellen über eine Lizenzaktualisierungsdatei vom Lizenzserver. Da kommt aber eine Datei mit anderem Dateityp (..WibuCmRaC) als im Lizenzmanager gesucht (WibuCmRaU). Die Datei ist dem Lizenzmanager auch nicht genehm (Bild Problem_Lizenzen_Raspberry_2.jpg). Nun steht Codesys auf besagtem Raspberry alle 2h still. Das soll die Lizenz doch verhindern. Angeblich soll seit SP13 auch kein eigenes Backup mehr nötig sein. Bis zum Erhalt des nicht brauchbaren Linzenzfiles hat da sja geklappt. Ich kann auch im Lizenzmanager keinen Punkt "Lizenz wiederherstellen" finden. Hat sich da mit SP20 etwas geändert? Wenn ich mir eine neue Lizenz hole - wie bringe ich sie auf den Dongle (der ja jetzt nicht "nagelneu" ist). Ich fürchte, das geht auch bloß schief. Im Voraus vielen Dank Thomas

I have a need to send messages between 2 PLCs and I cant use network variables (because of size limit) so I tried writing this simple test program. This seems to work fine. I can send messages back and forth when a first "Start server" and then "Connect client". See the attached image. However, if I disconnect the client by setting ClientConnect to false and try to re-connect then the TCP_Client just gives me TIMEOUT error. When I stop and start the server again, then Im able to reconnect. How is this supposed to work? Why reconnecting wont work. There is not other way of disconnecting the client than setting xEnable of the TCP_Client to false. This is just a testing program and I will try it on 2 seperate devices once this works.

I had this code working in a previous version of CoDeSys to read variables from a GVL that were added to the Symbol configuration. The problem now is that when I get the _IBaseTreeNode_Parent, it returns a valid interface, but none of the methods or properties work. If you monitor the _IBaseTreeNode in the watch window, it does show the correct child count. However, it fails at step 30, where the child count incorrectly returns zero. In the image, you can see that the watch window displays the correct value that the property should return. Attached is the full project code.

Post by smeitink on Timeout Error in Modbus Communication with WAGO PFC200 and iEM2050 Meter using 750-652 Module

Hi all, I'm looking for help with an issue I've come across while trying to facilitate Modbus communication between a WAGO PFC200 PLC using a 750-652 communication module and an iEM2050 Series Single Phase Energy Meter. I believe to have everything wired and setup correcty, but I keep running into a "Error time out" message, and by now I don't really know what else to try. My setup is as follows: A PFC200 Wago PLC, which has 2 750-652 Serial Interfaces extension modules connected to its field bus. I'm using one of these to talk to a Schneider iEM2050 - kWh-meter over modbus. I have connected terminal 23 (A) of the iEM2050 to connector 6 (A) on the 750-652. I have connected terminal 24 (B) of the iEM2050 to connector 2 (B) of the 750-652. I'm using 200mm of twisted together wires to connected them both, and I have placed a 120 ohm resistor between A and B at both ends. I've attached relevant pinout images to this post. I then wrote a simple program that configures the Mobus port, as per the datasheet of the iEM2050. You can find an image of the relavent page attached to this post too. This is my program: PROGRAM PLC_PRG VAR Master: FbMbMasterSerial; xIsConnected: BOOL; xError: BOOL; iIndex: INT := 1; xTrigger: BOOL; utQuery : typMbQuery := ( bUnitId := 1, // The Modbus unit or slave address bFunctionCode := 4, // Function code for reading input registers uiReadAddress := 1829, // adress for the Power on off counter uiReadQuantity := 1 // Quantity of registers to read ); iStep: INT; oStatusModbus: WagoSysErrorBase.FbResult; utResponseModbus: typMbResponse; xConnect: BOOL := FALSE; delayTimer: TON; END_VAR Master( xConnect:= xConnect, I_Port:= _750_652_24_1, udiBaudrate:= 9600, usiDataBits:= 8, eParity:= WagoTypesCom.eTTYParity.Even, eStopBits:= WagoTypesCom.eTTYStopBits.One, eHandshake:= WagoTypesCom.eTTYHandshake.None, ePhysical:= WagoTypesCom.eTTYPhysicalLayer.RS485_HalfDuplex, xIsConnected=> xIsConnected, xError=> xError, oStatus=> oStatusModbus, eFrameType:= WagoAppPlcModbus.eMbFrameType.RTU, tTimeOut:= T#5S, utQuery:= utQuery, xTrigger:= xTrigger, utResponse:= utResponseModbus); delayTimer(IN := TRUE, PT := T#3S); // Use the Q output of the timer to set xConnect after the delay IF delayTimer.Q THEN xConnect := TRUE; END_IF CASE iStep OF 0: //Wacht totdat de master de poort geopend heeft IF xIsConnected THEN iStep := 1; END_IF 1: //Stuur request naar de slave xTrigger := TRUE; iStep := 2; 2: //Wacht totdat de master klaar is met het afhandelen van de request IF NOT xTrigger THEN iStep := 3; END_IF END_CASE The TON delay before opening the port is due to a an error I encountered when opening it straight away. This seems to be a bug, as described here. However, the TON solved that particular issue. I tried reading multiple registers, but like I said, I still always end up with the "Error time out". What else can I test or try at this point?

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.
