Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge talk (Post)}
Some new test. Now I cannot connect from Automation server to my gateway in any way also from my office setup with my unit directly connected to my router by dhcp. I can use the IDE and the tool "Connect Edge Gateway" and successfully connect to my server/link to my Automation server account. However no PLC will respond from Automation server "Network scan". I guess the traffic should be initiated by the gateway towards automation server? Any tips on how I can diagnose my problem? Ports to be opened etc? Thing is that this has been working previously but not now (base system has been updated from debian 12 to debian 13, but I dont know at which point it has stopped working). Setup as before. A "Codesys Control for Linux SL" running on a debian 13 installation. Any help/tips appreciated! Per Update. Found the error. Had a wrong gateway-setting. Which meant the PLC could not reach internet. Checked by "ping google.com" from the PLC.

Post by fajean on Issue with library updates ^{CODESYS Forge talk (Post)}
We make heavy use of internally developed libraries, which are often nested on multiple levels. I routinely work simultaneously on several libraries along with a project that use them. I make changes to a library and immediately perform a download (online or otherwise) in the project. For the longest time, we had zero issue with this. But starting a good while back, with 3.5 SP19 I think, CODESYS started not noticing library updates in other instances most of the time. When the update is missed, the project sees no need to update the code, and any download ignores the new code. A "Clean all" does not solve the issue. But if I close and then re-open the project, then the new version is noticed and the download works. The other solution is saving the library to the registry multiple times (say, 20-30 times, less if lucky), and then at some point the project notices the changed library. I am now on SP21, and it is still not fixed. This is driving me mad, any tasks probably takes me double the time or more due to this problem. My colleague has the same problem on a separate computer. Is this a known issue? Is there a setting somewhere that changes how updates are checked? Thanks for any help!

Post by gmau on Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired ^{CODESYS Forge talk (Post)}
Hello, I am writing to You with the problem of Profinet communication in my Codesys V2.5 SP21 project working on Codesys Control RTE V3 x64 device. I have implemented multiple Profinet devices in the network, the Profinet itself is configured properly, based on the hardware and software parameters of the industrial PC (Windows 10 IoT). My Profinet network contains such Profinet devices as a robot, IO-Link master with some devices on it, IO modules, safety, vision sensor (the configuration is attached to this topic). Once every few hours, sometimes more often, sometimes not even once a day, the error show up at one, two or a few random modules at the same time, every one is the same: "Station 'xyz': AR aborted by device (alarm.ind): AR consumer DHT expired". The communication is then lost with that module, but it is up instantly. It is not such a problem when it comes to regular IOs, but with safety or rotation table, it causes errors and machine stops. I have tried multiple solution based on any forum suggestions, manuals, etc., but it is still happening. Mabye when I turned on the Watchdog for this communication, it is happening less times, but still, I could not turning up the Watchdog parameters at the expense of cycle time of the process. The same is with Send Clock, Reduction and DHT. I have one of the ethernet port on the PC configured with CmpEt1000Drv driver. The card itself is Intel Ethernet Connection I219-LM. These devices are connected to one EKI-2728-NI-A Profinet switch (it was changed from the standard non Profinet one, but still nothing has changed). As I said ealier, I am attaching all the configurations for each device and the communication itself - if any of You had the same problems or have any ideas what could be the cause, I would be much gratefull for any help. For now I am out of ideas, if You have any additional question, please ask. Sincerely, PF

Post by ara32 on CODESYS 4 Linux: ^{CODESYS Forge talk (Post)}
Hello! I managed to correctly launch CODESYS Developer Studio 3.5.17, almost all functionality works. The only issue remaining is that when connecting to a device and obtaining its public key, the NCryptEncrypt function is called, which is not fully implemented in the DLL source code, resulting in the connection not being established. Currently, the code of this function in the Wine repository looks like this: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG || flags & NCRYPT_PAD_OAEP_FLAG) { FIXME("No padding and oaep padding not supported\n"); return NTE_NOT_SUPPORTED; } if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } The program crashes due to the NCRYPT_PAD_OAEP_FLAG flag. I'm not proficient in C++, but I attempted to add handling myself, and here's the result: SECURITY_STATUS WINAPI NCryptEncrypt(NCRYPT_KEY_HANDLE key, BYTE *input, DWORD insize, void *padding, BYTE *output, DWORD outsize, DWORD *result, DWORD flags) { struct object *key_object = (struct object *)key; TRACE("(%#Ix, %p, %lu, %p, %p, %lu, %p, %#lx)\n", key, input, insize, padding, output, outsize, result, flags); if (flags & ~(NCRYPT_NO_PADDING_FLAG | NCRYPT_PAD_OAEP_FLAG | NCRYPT_PAD_PKCS1_FLAG | NCRYPT_SILENT_FLAG)) { FIXME("Flags %lx not supported\n", flags); return NTE_BAD_FLAGS; } if (flags & NCRYPT_NO_PADDING_FLAG) { FIXME("No padding not supported\n"); return NTE_NOT_SUPPORTED; } BCRYPT_OAEP_PADDING_INFO oaepInfo = { 0 }; oaepInfo.pszAlgId = BCRYPT_SHA1_ALGORITHM; NTSTATUS status = BCryptEncrypt(key_object->key.bcrypt_key, input, insize, &oaepInfo, NULL, 0, output, outsize, result, flags); if (key_object->type != KEY) return NTE_INVALID_HANDLE; return map_ntstatus(BCryptEncrypt(key_object->key.bcrypt_key, input, insize, padding, NULL, 0, output, outsize, result, flags)); } Now, when calling the connection, it crashes with the error "bcrypt:BCryptEncrypt flags 0x4 not implemented." Can anyone help with enhancing this functionality or at least point me in the right direction?

Post by dandyk on Dynamic Images ^{CODESYS Forge talk (Post)}
Hello, I have very similar problem, but it seems that your solution does not work for me. I am using TwinCAT XAE Shell v3.1.4024.55 and TwinCAT Runtime. Sorry for writing here on codesys forge, but since I found the only relevant topic here and since TwinCAT is almost the same with CODESYS in many applications, I chose to write here. I simply need to dynamically update image in visualization based on camera trigger (I am doing a machine vision application). Camera triggers an image, my program processes it (applies thresholding, draws contours etc...) and saves the processed image in the runtime location (the same one you were mentioning). This was done successfully. I need to make it work at runtime, while the program is executing and I need to refresh the image in the visualization each time camera triggers a new image and program processes it. When I create image element in the visualization and define the bitmap ID variable as STRING which contains the image ID defined in the image pool, then it displays the image in the image pool, but does not work at runtime, while the program is executing. I also used the Bitmap Version. I declared it in Global variable list as integer with initial value of 0 and wrote the variable in the bitmap version in the image element in visualization. Each time new image is saved to the runtime location, I wrote a program to increment Bitmap Version by 1. It increments and the image does not update in the visualization, unfortunately. I think that bitmap version is working correctly and deletes the cached image as it is supposed to, but the Image Pool does not update the image ID with the new image... the path to the image is always the same... only the actual image changes with the same file name. Image Pool is not dynamic and cannot refresh the image in the path to the actual one at runtime. How can I refresh the image ID in the image pool at runtime? Bitmap version only deletes cached image and reloads the image from the image ID, but the image ID has the same image, because image pool won't update at runtime. Do you know any solution to this problem?

Post by ppix on Establishing TLS Connection with MQTT Broker using MQTT Client SL Package ^{CODESYS Forge talk (Post)}
I’m currently working on establishing a TLS connection with an MQTT broker using the MQTT Client SL package in CODESYS. While I’ve successfully established communication with the broker without TLS, I'm encountering issues when trying to enable TLS. In the 'MQTT Explorer' application, I can easily upload the server certificate (.crt), client certificate (.crt), and client key (.key). However, in CODESYS, I can’t find a way to upload my client key (.key file). Here's a summary of my current setup: Certificates: I have uploaded both the client and server certificates to the certificate store under the 'Trusted Certificates' folder in the security screen. TLS Context Initialization: Despite setting the _sCommonName as the name of my client certificate, a new self-signed certificate is created and placed within the device’s certificates. I then need to manually move this certificate to the trusted certificates folder. This results in three certificates in my trusted certs folder: client cert, server cert, and the newly created cert. _ciDefaultCertInfo : MQTT.NBS.CERT_INFO := (psInfo := ADR(_sCommonName), udiSize := TO_UDINT(LEN(_sCommonName))); // CN of the certificate (common name) _sCipherList : MQTT.NBS.CIPHER_LIST := STRUCT(psList := ADR('HIGH'), udiSize := 4); // Cipher string see https://www.openssl.org/docs/man1.1.1/man1/ciphers.html _tlsContext : MQTT.NBS.TLSContext := ( sUseCaseName := _sCommonName, // A certificate is stored in the certificate store with the use case name. You can choose any name. Here we use the common name. ePurpose := MQTT.NBS.PURPOSE.CLIENT_SIDE, // For client certificates set this to NBS.PURPOSE.CLIENT_SIDE sTLSVersion := '1.3', // The TLS version sCipherList := _sCipherList, // Set the cipher list sHostname := sHostname, // The hostname of the broker udiVerificationMode := 2, // 2 => Active Peer verification ciCertInfo := _ciDefaultCertInfo, // Set the cert info itfCertVerifer := 0); // 0 => No Verifier mqttClient : MQTT.MQTTClient := (xUseTLS:=TRUE, itfTLSContext := _tlsContext, itfAsyncProperty := _asyncProperty); Additional Details: In the client FB, I’ve set uiPort:= 8883, xUseTLS:= TRUE, and configured itfTLSContext as mentioned above. The certificates are encrypted with SHA256RSA. sHostname is the IP address of my broker. I’ve attached a copy of the client FB, which shows straight lines where variables are assigned and boxes where they are not. I am currently trying this on the only 2 compatible versions of COSDESYS with my controller (V3.5.15.20 and V3.5.18.40) My Question: How do I correctly set up this mTLS connection? What might I be missing? Any guidance or suggestions would be greatly appreciated, especially considering I’ve already successfully established a non-TLS connection with the same broker. Thank you in advance for your help!

What are the limitations of the OPC UA Server? I am trying to get data off my PLC that is acquired at high rates (~50k samples/s) so I am storing them in arrays and trying to get the arrays off the PLC. When I attempt to read a ~200k element array through OPC UA the server and runtime crashes (requiring tools -> update linux arm64 -> start runtime). Is there a better way to get highspeed data off? The ACDatalog library seems a bit irritating to use so I would prefer to go through OPC UA.

Post by arnaud on eCockpit - unable to start simulation ^{CODESYS Forge talk (Post)}
Hi there! I'm using eCockpit WAGO software to develop HMI's for multiple projects. As I recently starting this, my knowledge on the software is somewhat limited (so maybe my question is a simple one). For most of my projects I can simulate the application and start it to test the code and HMI. However for two projects, I can initiate the "simulation activation" but I cannot start it. Nothing happens when I press start and the visualization shows "The online visualization is waiting for connection. please start the application". - I don't see any errors in the messages - Initially the project are made by a colleague, which moved on. I guess I'm forgetting something, like missing a setting. I appreciate any help I can get. If you need more information to help me out, let me know. Thanks!

ok, that's different than our issue then. We're using Schneider Electric M262 PLCs, and we've had it where certain web browsers cause the web server to only allow https connections, but it's not recoverable with a refresh. It usually requires a power cycle or even a full firmware flash. Your issue might have more to do with the timing. I don't know if it helps you, but we normally run our visu task at 200mS, with an update rate of 200mS. Seems to work. I went through this: https://faq.codesys.com/pages/viewpage.action?pageId=112525371 but it really seems like trial and error.

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
I have a project with several buttons and dialogs. Most of the dialogs are opened using the Open Dialog action of the Input configuration of the buttons. Some dialogs are openend using the FbOpenDialogExtended FB of the Visu Utils library and the FbOpenDialogExtended FB is called in the Execute ST-Code action. I am also using the FileOpenSave dialog from Visu Dialogs which requires an OnDialogClosed action to read out. I realized that the OnDialogClosed action which is meant for the FileOpenSave dialog also triggers if a dialog is closed, which was previously openend using the FbOpenDialogExtended FB. Is there a way to detect which dialog was closed last and specify to which dialogs the OnDialogClosed action reacts?

Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

Post by matthew on New Ladder Editor Issues ^{CODESYS Forge talk (Post)}
Hi There, When using the new ladder editor there is no option for function blocks to Remove uncalled FB call parameters. I also see no update function block. When you double click the function block it no longer opens the function block. I also now get warnings if I insert FB call without a contact in front. Warning is: (Impl)): C0373: Expression or part of it has no effect I take it the new editor must work differently? The only reason for using new ladder editor is the ST execute/block editing is far better, If you have alot of text in the old ST execute the editor window is very small and when online it's even worse. The new ST block seems a lot better Thanks!

I have a project called 'DemoProject' and a library called 'DemoLib'. Create a visual control named "DemoVisu" in the library, with a selection box of type "ComboBoxInteger" in the space. Now 'ComboBoxInteger' requires a 'Text list'. This "Text list" is provided when I call the "DemoVisu" control of the "DemoLib" library in "DemoProject". And this text list is in 'DemoProject'. I found that 'ComboBoxInteger' no longer works at this time. Other visual controls that use text lists also have this issue. I hope there is a good solution to this problem.

There are about 500 persistence variables, they are building another identical machine. I would like to use Persistence Manager files from the first machine in the second also. I have tried copying the files and replacing them on the new RPI but then the Persistence Manager gets errors and then they are all reset to 0 etc I have tried adjusting the times to match. Instead of replacing whole file, I tried just changing the contents inside the file, but still does not work. I may be missing something here, but surely there must be a way to load a backup. Thanks!

Post by bernd on Version 3.5.19.40 probleme bei FUN mit _to_ im Name ^{CODESYS Forge talk (Post)}
Hallo, ich habe von Version 3.5.19.0 auf 3.5.19.40 hochgerüstet, jetzt bekomme ich bei allen FUNs die "to" im Namen haben einen Fehlermeldung. Oft in der OSCAT.LIB verwendet. Gleiche Meldung wenn ich einen FUN neu anlege. Sobald ich das to weglasse z.b. nur "t" ist der Fehler weg. Programm ist unverändert. Fehlermeldung: Typ.... wird nicht unterstützt. Hat jemand das gleiche Problem? Bzw. wo liegt das Problem? Bzw. nutzt jemand das SP4 und bei ihm kommt der Fehler nicht? Läuft bei mir auf Rasperry. Beispiel: DT_TO_SDT -> Fehlermeldung Typ DT_TO_SDT wird nicht unterstützt. DT_T_SDT -> Übersetzung Fehlerfrei

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I'm getting closer to the error. The combination of STRUCT and ARRAY probably causes the strange behavior. As soon as the ARRAY is followed by a variable, the problem arises. Examples: X: ARRAY[1..2] OF INT; // okay Y: ARRAY[1..2] OF STRUCT; // problem Z: STRUCT; Z.ArrayOfInt[1]; // okay Z.ArrayOfStruct[1].Variable // problem // *update - array of array also causes the error A: ARRAY[1..2] OF ARRAY[1..4] OF BOOL; // problem I can't be the only one who has this problem. Or? Maybe there is a solution. Anyone? Or is it a bug after all?

Post by felipemsgarcia on Edge Gateway online, but PLC is not online ^{CODESYS Forge talk (Post)}
Hello, Up until yesterday (2023/11/20) I was able to connect to the PLC remotely with no issues through Edge Gateway. However, today I can see the Edge Gateway online but I can find the PLC even if I do a network scan. Following the same path as janber0206 @ https://forge.codesys.com/forge/talk/automation_server/thread/e78b11d7e9/, I looked into certificates and found that one of the Trusted publisher certificates has expired earlier today (2023/11/21). Please see image. Questions are: Does it affect the connection to the PLC through Edge Gateway? How do I fix it? Thank you very much in advance!

Post by captaincookie on SP19 Runtime Zugriff auf lokales Dateisystem ^{CODESYS Forge talk (Post)}
Hallo, das konkrete Problem konnte ich seither leider nicht lösen, allerdings habe ich mit SP19 Patch 4 einen Workaround gefunden, der zumindest für meine Anwendung funktioniert: Zunächst besteht das Problem nicht für alle Funktionalitäten gleichermaßen. Die Anzeige einer .bmp oder .tiff-Datei im Visu-Elementtyp Bild beispielsweise funktioniert aus dem lokalen Dateisystem. Die Anzeige von .cnc-Dateien in einer Tabelle dagegen nicht. Allerdings funktioniert das wiederum, wenn der Dateipfad in den Ordner der PLC führt, genannt '_cnc'. In der PLC wird dieser Ordner über den Pfad _cnc/ erreicht. Auch lohnt es sich einen Blick in die PLC Config-Datei zu werfen und ggf. Anpassungen vorzunehmen. Einzelne Einträge definieren Zugriffsrechte und ähnliches. Die beschriebene Lösung ist nicht sonderlich schön und es erklärt das Problem nicht. Vielleicht kann das noch jemand anders beantworten.

I would figure out, how to create a simple html webpage with 2 frames. One frame with buttons to select the plc. A second frame with hyperlink to the webvisu of the plc ("XXX.XXX.XXX.XXX:8080/webvisu.htm"). Selecting other PLC Button has to change the hyperlink in 2. frame. Costs only some time to figure out :-) Or setup a raspberry Pi with small visualization. Set up a button for each plc and add one browser element. Each button writes the URL of the depending plc to the URL setting of the browserelement. Costs 55€ for runtime licence and a Raspberry Pi.
