Post by timvh on Is it possible to use debug functions such as Step Execution while the PLC ladder is in Running? ^{CODESYS Forge talk (Post)}
Yes, it is possible to set breakpoints and use step into / step over (also in Ladder diagram). Yes, the PLC will actually stop, so be carefull with this. How a PLC works is that at the start of the execution of the Task, the Inputs are read, then the code is being executed and then the outputs are written. So if you set a breakpoint, you will not see your analog inputs changing, because the task cycle is interrupted and the inputs and outputs are not refreshed. For detailed information, see: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_using_breakpoints.html

Post by matthew on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
Hi It looks like in the new ladder there is no way to remove unused FB call parameters or update the function block? It's quite often where you have a function block with multiple uses and not all the parameters are required. Need the ability to leave an input/output blank without getting an compile error Expression expected instead of '' Also double clicking on the FB no longer opens the underlying FB code and view what it was doing online. Dragging and dropping a variable does not work, only using the selection works. Will these be available in the V1.0 release or just best to stick to the old ladder until it's available? Thanks

Post by tama00 on Datenübertragung mit SSP0 zw. uC und Raspberry Pi mit Codesys Runtime ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich arbeite derzeit an einem Projekt, bei dem ich einen Microcontroller habe, der Messwerte über die SSP0-Schnittstelle an einen Raspberry Pi senden soll. Diese Daten sollen dann in Codesys für eine Soll/Istwert Vergleich/Regelung verwendet werden, und das Ergebnis soll zurück an den Microcontroller geschickt werden. Meine Frage ist, ob es möglich ist, diese Kommunikation über die SSP0-Schnittstelle (als SPI frame format) zu realisieren, oder ob ich auf eine 'reine' SPI-Schnittstelle des uCs zurückzugreifen muss. Gibt es spezielle Dinge, die ich beachten muss, um diese Datenübertragung erfolgreich in Codesys zu implementieren? Ich wäre sehr dankbar für Ratschläge oder Hinweise, wie ich dieses Vorhaben am besten umsetzen kann. Vielen Dank im Voraus!

Post by dkugler on Toggling Visualizations using HMI Physical Buttons ^{CODESYS Forge talk (Post)}
the magic option is named "Use CurrentVisu variable" activate this option in the Visualization Manager an have a look: https://help.codesys.com/webapp/_visu_obj_manager;product=core_visualization;version=3.5.14.0 if your button is pressed, "feed" the string varable VisuElems.CurrentVisu := 'visu1'; with the correct name of the depending visu. alternative: place a frame element at a empty main visu, konfigure all visus to be shown by this frame. With setting the switching variable of the frame to the index value of the depending visu, it will switch to it. Advantage: the visu names are not hardcoded as string in the ladder lodgic. Good luck! Hint: If you have multiple VisuClients(Target, WebVisu,...) all will show the same visu. Independent switching is much more difficult, but there is a example from codesys.

Post by nmcc on How to address visualization change with button press... ^{CODESYS Forge talk (Post)}
Hello all, I am extremely new to Codesys and to programming with these languages in general. I have an HMI panel with 8 physical buttons to the right side of it. I am trying to have these set to change the visualization to a specific screen which I have designed 8 of. I currently have "use CurrentVisu" enabled in the visualization manager. I also have input blocks with all of the buttons being directed to output blocks which I want to have as the switcher for the visualization. Picture is attached for what I have currently. This could be the wrong approach to this issue. Any help is much appreciated.

Hi, My problem is with raspberry pi 4 with 2 GB ram,. Install codesys is correct but runtime works only few seconds or I can connect with device few seconds. I can ping raspberry and in system info I can see " !!!! Warning: no runtime license - running in demo mode(~2 hours)" but it is 2 minutes after runtime. When I press Start runtime I have another few seconds when I can connect to raspberry. After this time I couldn't find device. Of course, reapet start runtime works every time on few second. Raspberry is new and works with fresh install raspberry os 32 bit. Where should I start looking for solve of my problem ?

Post by tokamk on Dynamic setting of the modbus tcp/ip slave ip address ^{CODESYS Forge talk (Post)}
Hello, I'm working on a project which includes Panel-PC which communicates with a PLC through Modbus TCP/IP. On the PLC I have a CODESYS code which has Modbus slave objects. The Modbus slave objects have to have manually set IP address in order for them to work properly and the Ip address has to be the PC-Panels's IP. This project is going to a customer and they're using their own IP address realm. So, my question is that is it possible to configure these slaves in some other way, so that the customer doesn't need to modify the CODESYS project? I was thinking that would it be possible to set the IP address of these slaves from external source?

Post by timvh on CODESYS V3.5 SP15 Patch 2 won't open ^{CODESYS Forge talk (Post)}
This is almost always related to previously working with an additonal monitor. If you have placed CODESYS on that monitor, later start your laptop again and open CODESYS without that monitor, then Windows still places it in the previous position, but then it is not visible. So the solution by cehermanstad can be used to move it to the main screen to make it visible again. PS, another way to move it, is by pressing SHIFT and then right-click on the icon in the task bar, then select move. You can then move it with the arrow keys or your mouse.

Post by nilesh on Request for Assistance with Online Logic Changes in PLC System using Codesys ^{CODESYS Forge talk (Post)}
Dear Sir, We are writing to seek guidance regarding our current situation with the Opto 22 Groov EPIC PR1 PLC system. Over the past year, we have successfully downloaded and implemented logic using Codesys, and the PLC has been operational without issues. However, we now require minor modifications to the logic. Despite attempting to upload the modified logic, we are unable to see the "online change" option, prompting us to consider a direct logic download. Our concern is that during this process, certain digital outputs or analog outputs might momentarily disrupt operations, which is unacceptable given the system's continuous 24x7 operation. We have explored online changes in other PLC systems, but due to the absence of the last downloaded backup, we are unable to proceed confidently.

Post by fenicklar on Login problem with FileTransfer on Raspberry Pi 5 ^{CODESYS Forge talk (Post)}
Hello everyone, I'm currently trying to set up a FileTransfer function from a Webvisu to my Raspberry Pi 5 on Codesys 3.5 SP 19 Patch 6. I went in the files CODESYSControl.cfg and CODESYSControl_User.cfg and added : [CmpWebServerHandlerV3] AllowFileTransferServices=1 And it seems to be working. However, I cannot access my several Webvisu without putting my login. That's a problem because one of my webvisu is in kiosk mode on the raspberry itself and there is nokeyboard attached, it's just an information screen, but I can't view it. Is there a wey to enable the File Transfer without requiring to login ? Thank you for your time

Post by mp9876 on Problems with simulation in Window 10 ^{CODESYS Forge talk (Post)}
Hi Automa, it seems the solution you were bringing up on 2022-04-06 could really help me as I did not remember the password I initially set. My problem though is that I am using Codesys Control Win V3.5 SP19/60 (64 bit) and I cannot locate any of the files you listed up there. I have been looking inside folder: C:\Program Files\CODESYS 3.5.19.60\CODESYS\ and they appear not to be present at all neither in the CODESYS folder or any sub-folders. Uninstalling and re-installing unfortunately does not do the trick. Any idea how I could get out of the ditch on this issue ? Anyone else maybe ? Thanks

Post by superjojo2002 on Licensing info not available. ^{CODESYS Forge talk (Post)}
If support for a containerized CODESYS runtime with a license isn't feasible, then I've considered an alternative approach: I've purchased and activated a "CODESYS Control Basic S" license on my Windows notebook, where I already have the Codemeter Control Center installed. Upon activation, I can see the CODESYS license as active on my notebook. Subsequently, I followed the instructions provided in this link (https://faq.codesys.com/display/CDSFAQ/How+to%3A+Setup+a+Wibu+Network+Server+Access+for+Licenses) to configure the Wibu runtime in the CODESYS container to access my external license server hosted on my notebook by editing the CODESYSControl_User.cfg file accordingly. However, it's worth noting that I'm still receiving a response from the Licensing Manager indicating that the runtime is persistently searching for a dongle instead of recognizing the soft container. So how can I get my runtime licensed now? Any ideas?

Post by superjojo2002 on Licensing info not available. ^{CODESYS Forge talk (Post)}
I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool. Version 7.60c of 2023-Aug-09 (Build 5625) for Linux/ARMHF 64-Bit Copyright (C) 2007-2023 by WIBU-SYSTEMS AG. All rights reserved. So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Hello, we are porting a CNC project from codesys 3.5.16 to codesys 3.5.19. The project has lots of CNC programs with variables. now we get hundreds of messages like this. [WARNING] CNC Test SP19: TestCNC SPS: PLC Logic: Application: C0564: A reference to uninitialized variable varCNC is used for initialization of TestCNC_D. Accessing the uninitialized variable may result in unexpected behavior. The objects program_name_D are implicit generated by codesys. I see no way to generated them after the variables. Is there a way to correct the initialization order? We know how to suppress this warning. But we need a clean solution as the warning already saved us in a other nonCNC project.

Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

Dank umfangreicher Hilfe durch den Kontron Support kann ich nun wieder übersetzen. Es waren einige Bibliotheken auf einem älteren, nicht 64bit-kompatiblen Stand. Beim Öffnen des Projektes erscheint zwar ein Dialog zum Aktualisieren der Bibliotheken. Diesen hatte ich auch mit "Auf neueste setzen" bestätigt. Trotzdem waren etliche Bibliotheken im Projekt veraltet. Leider habe ich noch keine Stelle in der Online Hilfe gefunden, die die Zusammenhänge in der Bibliotheksverwaltung und das Vorgehen bei Fehlern erklärt. (Z.B. wie man vermeiden kann, dass eine Komponente automatisch eine ältere Bibliotheksversion lädt, obwohl eine aktuelle Version der gleichen Bibliothek schon hinzugefügt wurde.)
