Update: it seems that the license is detected by CODESYS on my computer but not detected by the runtime on my device. I'm using Codesys control for raspberry pi in the latest version 4.11.0.0 Is there something to do to correct this ?

Post by mjam04 on AM243 LaunchPad as PROFINET Device with CODESYS – RPC Aborted error when scanning devices ^{CODESYS Forge talk (Post)}
Hello, I am currently trying to use the AM243 LaunchPad as a PROFINET device and connect to it using CODESYS. In my setup I am also using a Raspberry Pi running the CODESYS PROFINET Runtime, which acts as the PROFINET controller. The setup of the Profinet controller is correct, so all devices are in the same subnet. However, I encounter an issue when scanning for PROFINET devices in CODESYS. The AM243 LaunchPad appears in the scan results, but the following error is reported: RPC Aborted: 0x16C9A049 Additionally, CODESYS shows the message that the identification data is not available and the IP address should be checked. Because of this error, the controller cannot establish a connection to the device. Another observation is that I cannot ping the AM243 LaunchPad from my PC, even though I configured what should be the correct IP address. Setup: PROFINET Device: AM243 LaunchPad PROFINET Stack: Industrial Communication SDK example PROFINET Controller: Raspberry Pi running CODESYS with PROFINET Runtime Engineering PC: CODESYS IDE Network: Ethernet connection between PC, Raspberry Pi, and AM243 In the attachments there is a screenshot of the corresponding error. Did anybody had the same error? Any hints or debugging suggestions would be greatly appreciated. Thank you!

Post by eoahe on Problem Reading Registers via Modbus from non Codesys device ^{CODESYS Forge talk (Post)}
Hey Guys :) I have the following Problem using Modbus via Codesys: I'm trying to implement a Modbus Device into my codesys project. The device is a Router from Teltonika (RUT956) and it can communicate via Modbus. Currently I'm trying to implement it into my codesys prject as a slave and I'm using my windows computer as master. As it is not a codesys device (the codesys application is not uploaded to device as it has its own software) I'm having problems requesting and reading registers from the router. I've set up my windows computer as Master and implemented the router as slave. When I go online on my master device it sais that it has established a connection to the slave (router)(So I'm thinking this could work as there is a connection?). The goal is to read the GPS (latitude and longitude) data and on the homepage of teltonika you can find the register address and number of registers (adress 143 for latitude and 145 for longitude; both have a number of two registers). I've found tutorials how to read specific registers via their register address with other modbus programs (like modbus-cli), but as my entire project is established in codesys I was hoping to read these specific registers via codesys so that I can show the GPS data on my dashboard. I've tried establishing slave channels but that hasn't been working. I tried read input register channels of the length 4 but it's not possible to define specific register addresses to read via codesys so that didn't work (I jsut get a slaves device failure) and I've also tried establishing 516 (total number of registers the router sends I think?) read inputregister channels but that has the samle failure... So i guess the problem I'm having is establishing slave channels to read these specific registers. Does anyone know how to tackle this problem and has maybe had the same problem? Or maybe someone knows a workaround? I'm quite new to codesys so maybe I'm also lacking expertise...

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Post by thierry-b on Blocking UDP ports 1740–1743 and 22350 to disable CODESYS network scan (startup + device discovery) ^{CODESYS Forge talk (Post)}
Hello, I am currently investigating the network behavior of CODESYS 3.5 (IDE + Gateway) in environments where the engineering workstation is connected to a very large /16 network. In such networks, the automatic device scan performed at IDE startup (and the manual “Scan Network” device discovery) can cause significant delays or freezes, due to the broadcast‑based discovery mechanism. After analyzing the traffic with Wireshark, I identified that the IDE uses the following UDP ports: 1740 – broadcast discovery 1741 – handshake / responses 1742 – fallback discovery 1743 – fallback handshake 22350 – additional runtime / gateway communication (WAGO, debug, extended discovery) To prevent the IDE from scanning the large /16 network, I tested blocking these ports in both directions (IN/OUT) on the network interface connected to the /16 segment (while keeping them open on the OT /24 network interface). Result: When UDP 1740, 1741, 1742 and 1743 are blocked on the IT interface, the IDE no longer sends any discovery traffic on that interface. The IDE still works normally on the OT interface (device discovery, online mode, download, etc.). Blocking port 22350 does not seem required to stop the scan, but I included it for completeness. My question: => Can you confirm that blocking UDP ports 1740, 1741, 1742, 1743 (and optionally 22350) on a specific network interface is a valid and supported way to completely disable the CODESYS IDE network scan on that interface (both at startup and during manual device discovery)? I am not trying to block communication with controllers on the OT network — only to prevent the IDE from scanning the large /16 IT network. Any confirmation or additional technical details about the discovery mechanism would be greatly appreciated. Thank you.

Hallo zusammen, ich möchte an einem Entwicklungsboard auf dem der i.MX 8M Plus von NXP aufgesteckt ist die vier zur Verfügung gestellten GPIOs als Ausgänge verwenden. Ich habe mir dazu die Readme-Datei des GPIO-Beispiels von "C:\Program Files\CODESYS 3.5.20.40\CODESYS\CODESYS Control SL Extension Package\4.14.0.0\Examples\GPIO" angeschaut Die Übersicht der verfügbaren GPIOs sieht folgendermaßen aus - wobei ich das auf die reduziert habe, die für mich von Interesse sind: gpiochip0: GPIOs 0-31, parent: platform/30200000.gpio, 30200000.gpio: gpio-0 (SODIMM206 ) gpio-1 (SODIMM208 ) gpio-2 ( ) gpio-3 ( ) gpio-4 ( |sd-vsel ) out hi gpio-5 (SODIMM210 ) gpio-6 (SODIMM212 ) gpio-7 (SODIMM216 ) gpio-8 (SODIMM218 ) gpio-9 ( ) gpio-10 ( ) gpio-11 (SODIMM16 ) gpio-12 (SODIMM155 |regulator-usb1-vbus ) out lo gpio-13 (SODIMM157 ) gpio-14 (SODIMM185 |regulator-usb2-vbus ) out hi gpio-15 (SODIMM91 )** Füge ich nun das GPIO (1 Bit)-Gerät in meinem Codesys-Programm hinzu funktioniert der Bus solange bis ich die Richtung in den GPIO-Parametern von "not used" auf "Output" stelle (siehe Bild gpio_parameter). Dann funktioniert nach Download der Bus nicht mehr. Gibt es noch eine andere Möglichkeit das zu steuern oder muss ich noch Einstellungen tätigen? Für die Zeile mit dem echo (export/unexport) aus dem Beispiel fehlen mir trotz sudo die Zugriffsrechte. "The Kernel Linux has deprecated GPIO user space SysFS. However, the kernel config CONFIGGPIOSYSFS is still enabled on Toradex's BSP to support customers using it in their legacy applications. You can check the configuration by running zcat /proc/config.gz | grep CONFIGGPIOSYSFS. For GPIO access from userspace, the new char device API, also known as libgpiod, must be used." Dies steht in der Verwendung der GPIOs - eine Ausführung des zcat-Kommandos liefert ein =y zurück.

System Hardware: Revolution Pi Connect 5 Runtime: CODESYS Control 4.16.0.0 (SDK 3.5.21.10) Development System: CODESYS V3.5 SP21 (64-bit) CommFB: 3.5.17.10 ProfinetCommon: 4.6.0.0 PROFINET Controller Device: PN-Controller 4.6.0.0 PROFINET Device: NORD DRIVESYSTEMS SK205E with SK TU4-PNT GSDML: GSDML-V2.46-NORDDRIVESYSTEMS-PNT-20251016.xml Network The PROFINET network is completely separated from the office network. RevPi: eth0 → Office network eth1 → PROFINET wlan0 → Visualization The PN Controller is configured to use eth1. IP configuration: RevPi (eth1): 192.168.100.1/24 NORD Drive: 192.168.100.3 Connection is established successfully. Current Status The PN Controller reports: Controller Status = Run Online = TRUE IP Active = TRUE Connections = 1 Cyclic PROFINET IO communication works correctly. Problem I am trying to access PKW parameters via WRREC (Record Index 100). The request buffer contains: 01 14 00 04 92 00 00 00 00 00 00 which corresponds to Reference = 0x01 Request = Read Axis = 0 Parameter = 170 + 1000 Subindex = 0 Value = 0 The WRREC call is fbWRREC( REQ := xWrReq, ID := ConnectionID, INDEX := 100, LEN := 11, RECORD := ADR(TxBuffer) ); REQ is pulsed for one PLC cycle only. Observed Behaviour WRREC enters BUSY state and never finishes. Observed values: BUSY = TRUE DONE = FALSE ERROR = FALSE STATUS = 16#FFFFFFFF indefinitely. Packet Capture A Wireshark capture was taken on the PROFINET network. Observed traffic: PROFINET RT LLDP DCP Observed: successful cyclic IO Not observed: DCE/RPC Record Write Record Read RPC Bind No RPC packets are transmitted at all. Diagnostic Messages The controller repeatedly reports AR alarm.ind(err) AR CMI timeout although cyclic IO communication continues to work. Already Verified The following points have already been checked: correct Ethernet interface (eth1) correct CREATE_ID result correct Device ID correct Slot/Subslot correct GSDML correct REQ pulse RECORD buffer is larger than LEN cyclic IO communication works different Record Indices (100...104) tested Question Is there any known issue or limitation where WRREC/RDREC requests remain permanently BUSY and no RPC Record Access packets are generated? Could this behaviour be related to Runtime 4.16.0.0, PN Controller 4.6.0.0, the missing runtime license (currently running in demo mode), or any known issue with the PROFINET Controller SL? I am currently evaluating the PROFINET Controller SL and therefore the runtime is operating in demo mode. Could you please confirm whether WRREC/RDREC (acyclic Record Data services) are fully supported in demo mode, or whether a valid license is required for these services? If required, I can provide: complete project archive Wireshark capture (.pcap) GSDML online screenshots diagnostic log Thank you very much for your help. Best regards, Stefan

Post by timvh on CANbus issue ^{CODESYS Forge talk (Post)}
On a PC with the Control Win, this is probably related to the fact that the CAN drivers are not loaded. Go to the folder where your Control Win Configuration file is: - E.g. C:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE - Open the CODESYSControl.cfg - Remove the semi-colon in front of the CAN driver you want to use (section ComponentManager). - Set the component ID to the next number in the list (e.g. Component.8) - Save this file and restart the Control Win.

Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Hi! I have som variables that I communicate to a Modbus Master. These variables are declared in a "Global Variable List" where I have assigned them memory addresses. To organize this mapping I want to make a MODBUS list where I show all the variable names together with the memory address. Is there an easy way to export this list from CODESYS? Either through script or some export function maybe?

you need at them moment a download once (for the configuration files generated including addresses) then stop the plc - exchange the persistence file ( without the config file) This will be improved to 3.5.18.6 and 3.5.20.0. (possible then to generate offline bootproject including full persistenmanager files) - this is if you have not 100% the same bootapplication on the devices. In case you copy the whole Application (PLCLogic) directory it should work out of the box - but only with 100% same bootprojects as mentioned above. By the CODESYS Automation Server would help solve this too.
