Post by brell on Automatic xExecute NBS.TCP_write ^{CODESYS Forge talk (Post)}
I've recently started experimenting with CODESYS for a project and am fairly new to it. I'm currently working with Function Block Diagrams (FBD) to set up TCP communication between a server and a client, where the client is implemented as a Python script. Once the communication is established, my connection status changes to True, which is the expected behavior. My challenge arises with the TCP write module, which requires the xEnable_write flag to toggle between True and False. If xEnable_write remains True, the module only performs a single write operation. To address this, I introduced a falling edge trigger (F_TRIG), expecting it to help in toggling xEnable_write and it does, However, I've encountered an issue where in the beginning after connxion established I need to manually set xEnable_write to True for the system to work as intended. I'm looking for a way to automate this process so that xEnable_write becomes True automatically upon establishing a connection . Initially, I tried setting xEnable_write to True from the start, but this approach didn't work well since it left the flag permanently True, preventing further toggling. I also experimented with using a TON timer, but I faced similar issues. I am seeking a solution that automatically toggles xEnable_write between True and False after a connection is established, ensuring continuous write operations without manual intervention. Any advice or guidance on how to achieve this would be greatly appreciated."

Post by zoronoa on J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup ^{CODESYS Forge talk (Post)}
Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically

Post by e13740e on Сalling the context menu from the keyboard ^{CODESYS Forge talk (Post)}
Hello. I have a question for you, perhaps you have an answer to it. Regarding calling the Context menu from the keyboard in Devices, specifically calling the context menu window from the keyboard via an assigned combination. Goal: to have the ability to navigationally add internal Objects (Methods, Properties) to Function Blocks from the keyboard without using the mouse. The Codesys environment interface does not allow Windows access to this via Shift+F10. Externally (outside the Codesys environment), the hotkey call for the context menu (Shift+F10) from the keyboard works in various environments, but at the same time, in Codesys it does not (it doesn't work). I have already tried various options on my own to achieve this (but unsuccessfully): Tools\Customize\Keyboard\Objects (the set combination does not give the desired result) Tools\Customize\Keyboard\Objects... (the set combination is extremely useful as it provides access to adding objects directly to Devices but does not provide the ability to add an internal object (Method/Property) to a Function Block). Thank you in advance for your help!!! P.S. I have already started trying to implement a script-based solution to call the context menu via AutoHotkey - by relocating the mouse cursor to the area of the navigational selection with a subsequent call of the context menu on it and relocating the mouse cursor back to its initial position. And in order not to "reinvent the wheel," I am writing this request to you!!!

Post by tanman19 on How to Use Personal Access Tokens from GitHub with Codesys Git ^{CODESYS Forge talk (Post)}
I am trying to push changes to a GitHub repository. I set up the Git Remote with the correct URL and committed the change. When I push the change it asks for my GitHub credentials which I know are correct, when I type in my username and password it gives me an error: "The provided credentials seem incorrect." So I tried putting in my Person Access token and when I put that in with my username I get this error: "The server request failed and returned a HTTP error code 403: Forbidden". Does anyone know how to correctly use Personal Access Tokens from GitHub with Codesys Git? Does it have to do something with the remote url or my username? Any help or guidance would be appreciated.

Hi guys I am trying to run on my laptop Codesys 3.5.19 Control Win x64 where I created a EtherCAT master. I have defined the controler, specified network adapter (my docking station) and everything worked as expected. Later I needed to test it on site (without docking station) so I changed the network adapter by EC master to my laptop network card. After that it shows "Network adapter opened" but no device can be found by scanning and in LOG is saying "SysEthernet: packet could not be sent, error code: -1". Same error with USB network card, but if I switch back to docking station, all is working again... Any idea what I'm doing wrong?

Post by c3po on SNMP Communication with WAGO 750-8212 PFC ^{CODESYS Forge talk (Post)}
Hello folks, my problem is a bit bigger for just one question. So let's start with the easiest. But first, my system setup: It's a WAGO 750-8212 PFC with some I/O-modules. I try to communicate with the controlsystem over SNMP using the IIoT library from codesys. https://content.helpme-codesys.com/de/CODESYS%20Examples/_ex_iot_snmp_service.html Is there some expirience with this kind of communication? It's just about transfering some data from PFC to network and setting some analogsettings from network to the PFC. So my easiest question: Do I ever need the SNMP_Agent or can I use the SET / GET function as standalone, without the agent? (maybe some more questions will follow, if someone will answer to my request) thanks so far

Hello guys, I have the following problem with the Codesys visualization (4.6.0) and Codesys V3.5.20.20. I would like to use my own HTML5 elements for my visualization. To do this, I have to select the option “Support client animations and overlay of native elements” in the visualization manager. But with the selection of this option, the visu has a massive loading delay when changing frame content. This happens even if I have not even added HTML5 elements. However, if this option is deactivated, then changing the content of the frames works without any problems, it loads instantly. I have already tried to change various refresh rates but without success. Have any of you experienced this and been able to fix it?

We are planning to update the SD card image of the Raspberry Pi to a newer OS version. However, we are concerned that this process might result in the loss of our soft container licenses. Is there a way to temporarily deactivate the license so that it can be reactivated on the updated system? Alternatively, what would be the best method to preserve the licenses during the update?

Liebe Forumsteilnehmer, hat jemand schon die Beckhoff-Multi-Klemme EL8601-8411 am EK1100 zusammen mit dem Raspberry Pi verwendet? Ich bin gerade am Testen und habe festgestellt - dass das mit dem Einstecken der Geräte nur teilweise funktioniert. - DI/DO und AI(U) lässt sich benutzen. - Den Zähler kann ich nicht testen, weil das Gerät nicht einsteckbar ist. Ich kann es zwar einstecken, aber dann läuft der Bus nicht. - Beim Encodereingang fehlt mir vermutlich ein geeigneter Funktionsbaustein um den zu betreiben. Gibts da evtl. irgendwo eine Bibliothek? Ich benutze CODESYS V3.5.19.70, habe die neuesten Gerätedateien (XML) von Beckhoff eingespielt und für den Raspberry Pi benutze ich die Version Codesys Control for Raspberry Pi 4.14. Für Antworten bedanke ich mich schon mal herzlich VG A. Hofer

Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue. If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input. Best regards

The Special characters that I need to inclue inside the string are as follows; Null Bell Carriage Return I have a TCP_Write command that I am sending to an external device. In order for that device to function properly it needs to see the string with the null and bell characters as the header, followed by the desired command, terminated with the carriage return.

I am also having this issue. It was working fine for the first 2ish months and is now throwing this error. I can just try and go online again a second time and it works. I'm wondering if there is an environmental variable or something that isn't set that is causing it to use an empty path as a temp directory. The empty path will be the location the app is running from which is that path C:\Program Files\CODESYS 3.5.19.50\CODESYS\Common. The permissions don't allow a normal user to write to that directory which causes the error. It also only seems to happen when there are changes or the build has been cleaned.

Tool -> License Manager Selected Device and Next... Selected Soft container and Next... Select the device and Ok.. And then I always show a message "Licensing info not available. There is no dongle attached to the device." And I tried to click "Install Licenses" button. I saw the message "The value cannot be NULL. Parameter name : continerToLicenses" Could you let me know what I've missed or what I've got wrong?
