Also had this problem when working on legacy project. My packege was CODESYS Code Generator ARM 4.0.3.0.package. To manage this I used PackageManagerCLI.exe. This tool does not validate certificates appearently. My command: "C:\Program Files\CODESYS 3.5.17.30\CODESYS\Common\PackageManagerCLI.exe" --profile="CODESYS V3.5 SP17 Patch 3" --install=""C:\Users\sample_user\AppData\Local\Temp\APInstaller\5wx1k02a.r2t\CODESYS Code Generator ARM 4.0.3.0.package""

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.

Open the CODESYS Installer (from the menu Tools). Go to Browse. Search for: help ... Select the CODESYS Offline Help which you would like to install. (probably you have to close CODESYS to install it and reopen it after installation).

Do not filter on Phoenix devices. First add an Ethernet device (from CODESYS). Then add a Profinet Controller (from CODESYS). Then add your Phoenix devices to this CODESYS Profinet Controller.

Post by patrik on Wish: CODESYSControl.cfg - again ^{CODESYS Forge talk (Post)}
Really good post. I hope that it gets seen by CoDeSys staff. I often find the documentation lacking when it comes to using CoDeSys in more complex ways. If using standard "basic PLC functionality", then it's fine and functions are documented in a sufficient way. Once you go outside of that bubble then I find the documentation not enough. CODESYSControl.cfg is a good example of this. And why isn't more of this integrated in the IDE. like changing port of the webserver. Why is it hidden in this file and not accessible through the IDE. It feels like a layer of complexity purposely left in so you don't change it if you don't know what you are doing. Like the argument is if you have the know-how to find the file you have the know-how to edit it. I find the documentation lacking when it comes to more complex libraries too. Like the element collections library. there is parameters I still don't quite know what they do. I can't find any documentation about them. There is an example project to download from CoDeSys so you can see how you are supposed to set your factories up. I leave some parameters like it is in the example. Should I? I don't know. Does it work. Yes. But I could perhaps create memory leaks if I get something wrong and I don't see that until way later. In the create method of your element factory you have a function called __vfinit and you just have to accept that it works. Why can't I get insight in what it does through documentation? Don't CoDeSys want us to know how these work so we can't use them to accidentally break something? I find the error logging lacking too. I've had the CoDeSys service crash but it doesn't say why. I've seen windows noticing the crash but no error code was sent or error message. Also in my current issue where the application fails to start after power outage. I can see in the log that it fails to load retain in the application as one log entry and application failing to start as another. But why? Why does loading the retain fail? give me more information! Is it just a skill issue with me? I don't know. If it is then I'd still want CoDeSys to step up their game when it comes to documentation. I'm sorry if a lot of frustration comes though in this post. I really like the product and what I can do with it compared to other PLC brands.

Post by sahin6033 on DSE M840-001-02: DSEServiceTool transfers CodesysApp.pkg successfully, but device shows “No application loaded ^{CODESYS Forge talk (Post)}
Hi, I am trying to load a test application into a DSE M840-001-02 display, but after reboot the device still shows: “No application loaded” I would like to understand whether the problem is in my project, the package creation process, or firmware/runtime compatibility. Hardware Device: DSE M840-001-02 Firmware used: M840 MKII Firmware File v4.1.2 Software CODESYS V3.5 SP12 (32-bit) DSE CODESYS Package v1.5.44 DSEServiceTool What I did Created a new empty Standard Project Selected target/template: M840-02 V4.1 Used a minimal ST program only: PROGRAM PLC_PRG VAR xAlive : BOOL := TRUE; END_VAR Confirmed: project builds PLC_PRG is assigned to MainTask created Boot Application Generated CodesysApp.pkg Put the M840 into bootloader mode Sent the package using DSEServiceTool DSEServiceTool result Transfer completes successfully and I get: connection accepted 100% download package ACK <status>OK</status> ** Example log:** Searching for controllers.... sendPackageToController: waiting for incoming data connection... sendPackageToController: connection accepted... <status>Downloading</status> <percent>20</percent> <percent>40</percent> <percent>90</percent> <percent>100</percent> sendPackageToController: sent 112cb8 bytes OK Package ...\CodesysApp.pkg transferred to controller c0a80101 OK sendPackageToController: package ACK <status>OK</status> Actual result After reboot, the display still shows: “No application loaded” Additional issue I also saw earlier At one stage I also had these fatal errors in CODESYS: [FATAL ERROR] Unresolved reference: 'IOMGRLOCKENTER' [FATAL ERROR] Unresolved reference: 'IOMGRLOCKLEAVE' I checked library versions and adjusted them to: IoDrvBase = 3.5.5.0 IoStandard = 3.5.10.0 Also, I am using CODESYS SP12, which I understand is the correct version for DSE M840. My questions If DSEServiceTool shows Status OK and package ACK, but the device still says “No application loaded”, does that mean: the .pkg was transferred but not accepted as a valid application? the package was built incorrectly? the boot application / runtime / firmware versions are still mismatched? What is the correct procedure to generate CodesysApp.pkg for M840-02 V4.1? Is there any known compatibility issue between: DSE CODESYS Package 1.5.44 M840 MKII Firmware 4.1.2 CODESYS 3.5 SP12 Has anyone successfully loaded even a minimal empty test project into M840-001-02, and if so, what exact versions/process did you use? Any help would be appreciated.
