Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Here, it seems to me that we are getting completely off track with the observed problem. If questions clarifying the details of the installation are problematic, it's best to include those details in the original question then... I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. Testing the full program in emulation is entirely different from creating a simplified program to isolate the function causing problems in the real world. I would recommend trying it to isolate the issue. The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem A simple "yes" is the correct answer to my question here... Anyways, you seem to be a very knowledgeable expert, good luck on your problem!

Post by atcprojectteam on Modbus Function Code 15, writing multiple coils ^{CODESYS Forge talk (Post)}
Hi all, I am using an RSTI-EP I/O card along with the EPXMBE101 Modbus/TCP network adapter. I have a Control Standard L license. I successfully connected to the I/O card via Modbus and can read inputs without any issues. However, when I try to write to the digital output modules using function code 15, I am unable to make any changes. Here’s what I have done so far: I created a small project using Structured Text. I set up Modbus channels (as shown in the attached image) and mapped the pins. When I use cyclic mode, the connection results in an error. However, when I use the rising edge, the connection works, but I don’t see any changes on the I/O card. For the output module, I assigned one bit to high. After that, I ran CODESYS Control Win V3. (Should I be running the PLC as well?) I built the program, but I am not receiving any response from the I/O card. Could you please advise on what might be causing this issue?

Post by razebones on sdo read write codesys 3.5 ^{CODESYS Forge talk (Post)}
ENG For some reason, I can't bind a variable to the data parameter. Also, why does only the sdo_read4 function work for me? I also can't write through sdo_write4. I can only view the received values via sdo_read4. Please help me with this task. Moreover, I tried to write the values through sdo write 4 and for a while the data stopped being written and I overwritten it manually and sdo read4 started working again and at the same time they do not want to work in the main task. RU Я не могу почему то привязать переменную к параметру data. Так же у меня почему работает только функция sdo_read4 так же не могу записать через sdo_write4. Могу только просматривать полученные значения через sdo_read4. Помогите пожалуйста с этой задачей. Причём я попытался записать значения через sdo write 4 и у меня на какое то время перестали записываться данные и перезаписал вручную и sdo read4 начал работать снова и одновременно они не хотят работать в main task.

Post by rene-h on ClientFilter used the same Client ID 2 times - Bug? ^{CODESYS Forge talk (Post)}
Hello, like the topic name says, i have a problem on one Visu which i cannot reproduce on another Visu. We filter buttons with input locks and visible items with [CURRENTCLIENTID] on different WebVisu's with different ID's, and one time the itfClient used the same Client ID for 2 Clients, so the Visualization on the first ID was wrong, because that one which connected after did not have the same permissions like the first, so the first one was blocked. We read the Clients with the VisuClientIteration project: //count active clients gCli.iNumberOfClients:=gCli.iNumberOfClients+1; // if client is active write data to global struct IF gCli.iNumberOfClients > 0 THEN gCli.astClientInfo[gCli.iNumberOfClients-1].iClientID:=itfClient.ClientId ; gCli.astClientInfo[gCli.iNumberOfClients-1].stCurrentVisu:=itfClient.CurrentVisuName; gCli.astClientInfo[gCli.iNumberOfClients-1].wsUserName:=itfClient.UserName; gCli.astClientInfo[gCli.iNumberOfClients-1].sIpAddress:=itfClient.GetIPv4Address(); gCli.astClientInfo[gCli.iNumberOfClients-1].ClientType:=itfClient.ClientType; END_IF Runtime from the device: 3.5.19.20 Codesys we use: 3.5.20.10 I added a screenshot where the same ID exists 2 times.

Post by canplum on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
Although I have set in /etc/codesyscontrol/CODESYSControl_User.cfg the [SysFile] PlaceholderFilePath.1=/media/pi, $usb$ PlaceholderFilePath.1.View=1 PlaceholderFilePath.1.Volatile=1 I am not able to copy a file to this directory defined by the placeholder. Neither SysProcess.SysProcessExecuteCommand2 nor SysFileCopy nor FileCopy is working. If I try to copy the same file to /home/pi all is working fine. I also can create and open a different file by using SysFileOpen. I don't understand why the system allows to open (create) and write files into that directory but doesn't allow to copy into it. Obviously there is a rights problem with the USB drive. I have already set the permissions to drwxr-xr-x 2 and the user to pi but without any success. With 3.5.16 I never had such an issue. Is there anybody with some hints how to solve that problem? Cheers, canplum

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Web Client Library Documentation Company: 3S - Smart Software Solutions GmbH Title: Web Client Version: 1.0.1.7 Categories: Application|Utils Namespace: WEB_CLIENT Author: 3S - Smart Software Solutions GmbH Placeholder: WebClient I encountered an issue using this library above. Note it is now part of Codesys IIoT Libraries SL in the form of Web Client SL, but I am not using this version. I was sending Content-Type: application/json, HTTP POST using a HTTPS URL. No issue observed initially, successful operation. At some point operation stopped and the codesyscontrol.log file started to accumulate errors: ERROR: TlsCreateContext2: Failed to save context. An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.

Post by latassan on RaspberryPi 5 gateway problem ^{CODESYS Forge talk (Post)}
Hello, I'm trying to use a raspberryPi 5 as a PLC. I fixed its IP address, I can ping it. I've also installed the CODESYS Control for Raspberry Pi 64 SL runtime on it. So I've created a gateway (IP address of the Raspberry, TCP port 1217). I see the green dot next to this gateway. When I do a network scan, I can see my raspberry (see photo). When I try to connect to it, I have to define an administrator profile, which I do. On validation, I see a message: No device is responding to the scan request. I've checked that port 1217 is listening on the raspberry, I've uninstalled the runtime then installed it again, but I can't connect. Also, when I try to configure the user groups before connecting, I see that Offline mode is not supported by the device, even though I'm connected to it in the Deploy Control SL tab. When I try to refresh, I see: Gateway not configured properly. How can I connect to my Raspberry? Have I defined my gateway incorrectly?

Post by chris--o on ModbusTCP RaspberryPi zu Fronius Wechselrichter ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich hab ein kleines Problem bei einer Modbus TCP-Verbindung von meinem RaspberryPi (ML) zu einem Fronius Wechselrichter. Ich habe mir die CodeSys Version 3.5SP20 heruntergeladen und die Runtime auf dem RaspberryPi mit aktualisiert. Gerät ist ein Fronius Symo 6.0-3-M Folgende Konfiguration habe ich im Wechselrichter (Siehe Bilder). Laut Registertabelle fangen die Daten bei Adresse 40001 an und gehen im Modus int+SF bis 40120 Ich habe mir also im Ethernet-Adapter einen Modubus Master und darunter einen ModbusSlave angelegt. Der Slave (Fronius) hat bei mir die IP 192.168.2.46 dazu UnitID und Port. Ich habe dann einen Kanal mit den 120 WORDS und dem OFFSET angelegt. Wenn ich nun die Konfiguration übertrage , scheint erst mal alles zu passen.. aber es flackert immer wieder ein Fehler beim Slave auf (kann nicht erkennen welcher und finde auch keine Diagnose). Es werden auch keine Daten übertragen. Alles bleibt auf 0. Ich muss dazu sagen, dass ich noch eine weiter Modbus TCP Verbindung zu einer anderen SPS habe. Die funktioniert wunderbar. Normalerweise sollten ja auch mehrere Verbindungen gleichzeitig möglich sein oder? Wäre top, wenn ihr mir helfen könntet, den Fehler zu finden. LG Chris

Post by westcountryewe on Displaying a Target Web Page on WebVisu ^{CODESYS Forge talk (Post)}
I have a main PLC with my CODESYS project on, including Web Visu. I also have a second device used for pump monitoring, all of this is displayed on a seperate HMI. I am looking at displaying the pump monitoring HMI on WebVisu so that I can solely use 1 HMI rather than having two. I can project the pump monitoring HMI into Chrome, and log in and it works fine. When I'm using the Web Browser element in Web Visu, enter my URL (device IP) it shows me the web page, but doesn't show me all of it. It uses parts of JavaScript for the login authenticiation and various other widgets. Similarly, I cannot get Youtube or Google to display on WebVisu either (possibily because of the same reason). Does anybody have any tips on how I can display the likes of Youtube or Google onto WebVisu so I can view it on my 7inch HMI (I suspect that if I can get Youtube or Google to work, then I will also be able to get my pump montitoring web page to work too).

Post by pernockham on Pointer/reference to Codesys trend recording object? ^{CODESYS Forge talk (Post)}
I have a Hmi that acts as an interface for many (mostly identical) units. This is managed by a sort of "mux" where you select which unit that should be presented on the HMI. Backbone is solved by a HMI-gvl defined as reference/pointer to "unit-data", which then can be set to the individual units. While this works for most data I still have not sorted how to solve this for the trend recordings. One solution would be to have already "mux:ed" data values as source for the/one trend. However then the trend would contain data from different units/sources which could/will cause confusion. If its possible to "clear" this can be mitigated. Possibly let the trend have its own "mux-selector" (ie, the hmi are focusing on unit#3 however trend data is locked on unit#5), that could also work.. Or, let each unit have its own trend recording, which is focused if the unit is "selected". Can I reach the trend recording objects programmatically (those defined in the device tree)? Ie, can I use a "reference/pointer to these trend recording objects"? There is a field "data source" in the trend properties dialog which seems to resemble what Im looking for? But Im not sure if I can use it in some way, I cannot change anything in this field it only says <local application="">. </local>

Post by beavel on Feature Request: Text List Formatting ^{CODESYS Forge talk (Post)}
Hi everyone, I'm working on a multilingual help system within a CODESYS visualization project and have run into a limitation with the current text list (.tlx) functionality. Right now, text list entries only support plain text, which makes it very difficult to format longer help texts in a readable way. For example, I’d like to: Use bold headers and larger font sizes for section titles Display variable names or keywords in italics Avoid having to split content into dozens of separate entries just to apply different styles This becomes especially unmanageable when supporting multiple languages — duplicating layout logic across languages is not scalable. Would it be possible to implement a Markdown text functionality for text list entries ? For example: #Header ##Sub-header 1.ordered 2.list 3.fun 4.times Alternatively, is there any existing workaround or planned feature that allows for styled text blocks without fragmenting the content? Thank you in advance and have a nice day :)

Post by gseidel on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
Hi SLUCodesys, dwErrorId is a drive specific error number. The drive documentation should be consulted to interpret it. (Note that you should use MC_ReadAxisError to read this error, see https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/MC_ReadAxisError.html. Accessing the internal variable will result in outdated values if the acis error is not mapped by PDO and is not recommended in general.) uiDriveInterfaceError holds errors of the SoftMotion driver for the drive. It is also an internal variable, not intended for direct access. It is intended for logging, the PLC log will contain the drive interface error, consisting of this number and an error text. My recommendation for handling axis errors in the CODESYS application: 1) Use MC_ReadStatus on the axis to find out whether it is in state Errorstop 2) If in Errorstop, there are two possibilities: an error reported by the drive (MC_ReadAxisError) or an error of the SoftMotion function blocks (output MC_ReadStatus.FBErrorOccured). 3) If there is no drive error, you can use SMC_ReadFBError https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/FBError/SMC_ReadFBError.html Best regards, Georg

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Sorry for the question, but I'm not completely getting the idea here, could you be more specific, maybe give an example? I'm now in a state where I don't have a softcontainer on my license server anymore (even after reinstalling from the Codesys-IDE). I tried reaching the webserver of Codemeter but when I do that I get redirected to http://"IP":22352 This is not reachable, afterwards I installed lynx on my Debian machine (command line only). From here I could reach the webserver and toggle the network server setting, but unfortunately this did not help. I also tried to changed the remote read setting to 1 (in the Server.ini file). But after a Codemeter reboot this is overwritten to 0. I have the feeling that it should be much easier to get a license to work, am I missing some checkbox somewhere? Is there a tutorial (or manual) that explains the licensing sequence step by step, because I'm pretty stuck.

Post by timvh on Licensing info not available. ^{CODESYS Forge talk (Post)}
In the VPLC configuration settings there is an entry for the IP address of the license server. In this setting fill in the IP address of your device (host IP address). Then when the virtual PLC starts up, it will get the license from the license container on the host. You can do this for all VPLC's running on your device. The VPLC will always take the smallest license which fits the required license. So if you have 2 licenses for VPLC's with small and large applications, then this will work fine if you start up one VPLC which requires the small license and the other which requires the large license. PS, personally I find it much easier, especially for testing and experimenting, to activate the licenses on a CODESYS (USB) key. This is easy to activate (on your development PC) and easier to move to another device. Addtionally you don't loose the license when you need to install a completely new image on the device.

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."
