Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.

Post by berto on Opening PDF in Web Browser in Target Visu HMI ^{CODESYS Forge talk (Post)}
Hi everybody, I've been facing problems with the PDF visualization in Web Browser. I am trying to open a pdf file called 'sample.pdf' which I manually saved inside PlcLogic/visu folder. I am setting the web browser URL as: 'http://127.0.0.1:8080/sample.pdf' but I get 'refused connection'. I got a similar error trying to open https sites and I discovered that I can only open http websites. Opening 'http://de.wikipedia.org' everything works fine. I also tried to check using code whether the sample.pdf is present in the directory. Unfortunately, when I try to read directories of 'PlcLogic' I get file FILE_OPERATION_DENIED (I am using File.DirList). I would like to be able to open PDF files in web browser. Possibly to move new PDF files in the folder as my customer wants to display different pdf manuals on the hmi. Here you find some screenshots and my .project. I am using Codesys 3.5.19.70. Best regards, Berto

Post by trusty-squire on Confused by dwIpoTime input for SMC_Interpolator ^{CODESYS Forge talk (Post)}
Hi, Learning Codesys CNC, and I am confused by the dwIpoTime parameter. I have a basic demo application, using SMC_Interpolator feeding into SMC_TRAFO_Gantry2Tool2, which then sets the position of the x/y SM_Drive_Virtual axis. I also have a C axis which revolves the tool, which is controlled using a simple tangential angle calculation SMC_CalcDirectionFromVector. The GCode I'm using has feed/accel set at 500. The axis configuration limits are well above that (2000). What's strange is that, when I run the simulation, the feed speed changes drastically when I update the variable dwIpoTime. The larger the number, the faster it moves. What's going on here? The documentation only says "This variable has to be set for each call. It represents the cycle time in μsec." Why does it change the feed speed I'm seeing the in simulation? What is a good number to use? The example I was looking at set it at 5000. Screenshot attached.

Post by timvh on How to implement an interface (IElement)? ^{CODESYS Forge talk (Post)}
See: https://forge.codesys.com/prj/codesys-example/element-collect/home/Home/ This contains an application "OnlineChangeSafeLinkedListExample". What you should do is create a new interface which has your "Priority" property. Then your FB should extend the base element function block and implement your own interface: E.g. FUNCTION_BLOCK MyElement EXTENDS COL.LinkedListElementBase IMPLEMENTS I_MyInterface Then the __QUERYINTERFACE does the magic to check if your "element" also implements your interface. Something like this: // Compares this element with itfElement. // Returns 0 if the elements are equal, < 0 if the element is less than itfElement, // > 0 if the element is greater than itfElement. // This method will be called from sorted collections (e.g. |COL.SortedList|) to sort the elements. // IMPORTANT: The underlying value to be compared with MUST NOT be changed during the lifecycle of the object. METHOD ElementCompareTo : INT VAR_INPUT (* The element to compare*) itfElement : COL.IElement; END_VAR VAR itfIntElement : I_MyInterface; xResult : BOOL; END_VAR // We use integer iInt1 for sorting. xResult := __QUERYINTERFACE(itfElement, itfIntElement); IF xResult THEN IF iInt1 < itfIntElement.Priority THEN ElementCompareTo := -1; ELSIF iInt1 > itfIntElement.Priority THEN ElementCompareTo := 1; ELSE ElementCompareTo := 0; END_IF ELSE ElementCompareTo := -1; END_IF

Post by denkihitsuji on Content update through Data URI on Web Brower on Visualization Toolbox ^{CODESYS Forge talk (Post)}
Objective: I want to dynamically update the content with strings and JPEG images received from a TCP/IP socket. For this purpose, I am exploring the possibility of utilizing the Web Browser feature of the Visualization toolbox. Example: In a standard web browser, entering data:text/plain;charset=utf-8;base64,SGVsbG8gc3RyYW5nZXI= in the URL window will display "Hello stranger" on the webpage. Issue: When attempting to use this method in the Web Browser of the Visualization toolbox, the content does not display as expected. Instead, it shows the error:'Navigation to the webpage was canceled.'. Request: I seek guidance on how to resolve this issue so that the Web Browser in the Visualization toolbox correctly interprets and displays the data URI content. Alternative Solution Welcomed: Or, if it is possible to directly use Codesys Structured Text (ST) variables within an HTML page, this approach would also meet my requirements. Thank you for your attention.

Post by sturmghost on Mimic behavior of the visualization button element with a custom button ^{CODESYS Forge talk (Post)}
Im wondering how Codesys is doing the mouse event capturing with their visualization button element? If you add such a button without configuring any input configuration event (like OnMouseDown) or button state variable and then click on the button, the button changes to the visual pressed state and back if you release the button (so they must react to an OnMouseDown event). But how? If I try to mimic this behavior with my custom button visualization element (like a basic rectangle) I need to use an input configuration event to change the color of the button (to make it look like the button was pressed on OnMouseDown event). When I try to add this button via a Frame-Element to my main visualization page I'm unable to use an input configuration event on the Frame-Element because the input configuration event on the button element won't be evaluated anymore (it seems like you can't stack input fields, e.g. invisible input elements, onto each other). Hence the button is not shown pressed anymore. How they do it?

Post by c3po on Von SNMP auf IIoT wechseln ^{CODESYS Forge talk (Post)}
Hallo, 1. ich bin komplett NEU was Codesys angeht 2. ich muss direkt ein Retrofit machen von V2 auf V3 3. Neue Steuerung: WAGO 750-8211 PFC200. 4. das Projekt in V2 hat über SNMP daten im Netzwerk zur Verfügung gestellt, oder diese gelesen 5. das Projekt in V3 kann SNMP nur noch eingeschränkt nutzen, deswegen wurde mir vom WAGO Support nahegelegt die IIoT Lib zu verwenden. Frage: Wie mach ich das? Konkret: Ich habe die WagoAppSNMP Bibliothek installiert, damit kann ich schon mal Set und Get nutzen (hoffentlich, hab es ja noch nicht getestet, sondern nur programmiert). Ist das ein schlauer Weg, das über diese Lib zu machen? Denn: was macht der SNMP_SET_PLCDATA_WRITEAREA ? Den kann ich über die Wago Lib nicht nutzen und weiß auch nicht, was dieser Baustein konkret tut (Bild im Anhang). Es scheint mir, hier werden Daten auf ein Word im Netzwerk geschrieben? Aber geht das nicht auch einfacher? Es ist ja keine Adresse hinterlegt, wo das hin gehen soll oder? Also, ich verstehe den Baustein nicht so ganz und konnte bisher auch keine Erklärung dazu finden. Vielen Dank schon mal für eure Unterstützung, K.

Post by bruceae on Ethernet/IP Scan ^{CODESYS Forge talk (Post)}
Hello, I have a robot configured as a Generic Ethernet Module under Ethernet/IP Scanner. I can not see the change of state of the outputs coming from the robot on the codesys side in real-time. (The robot has it's own internal program that would changes the values of remote outputs 0-3 off and on). Also when I send data down to the inputs of the robot it doesn't transfer over as expected. As an example I'll send to the robot's input bit 0 a value of 1. It doesn't see that value change. However, when I write that input bit 0 back to a value of 0, the robot changes state and shows a value of 1. And if I change the state of a different bit, the other bits update properly, except for the bit that I changed. Any advice would be greatly appreciated, and if anything else is needed let me know.

Post by bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Hi, I would like to divide a project into multiple applications - as a minimum: one handling visualization and Alarm Manager, one handling I/O and plant control logic. But how to exchange variables between the applications? What have you done to get such a solution? In versions 3.5.19 and earlier, you can have Child applications, where the children can access a GVL in the Parent application. Children apps is no longer possible in 3.5.20 - but you can have 'sibling' apps - Several apps directly under PLC Logic, that is. But how do they best communicate? The Communication Manager / Data Sources Manager is sort of possible via OPC UA, but it seems like overkill and with some limitations - for example no ARRAY OF STRUCT possible this way. If you have separate devices in your project, you can exchange data via 'CODESYS ApplicationV3', but not other applications in the same device (see attachment Datasources.png). You can do it via 'Select the project type'->'Other Project' and select the same project file, but this leads to crashing the Development system when working with the variables afterwards. It would be great to hear your thoughts / experiences on this topic - Bjarne

Post by z870623 on About CPU Loading ^{CODESYS Forge talk (Post)}
I am running a runtime environment on an ARM A35 dual-core processor (1.5GHz) and have encountered some issues. The CPU load (both CPU0 and CPU1) occasionally spikes above 50% before returning to normal, and this happens around 2-3 times per minute. At the same time, I’ve noticed that the Max Cycle Time in the Codesys monitoring screen shows much worse performance compared to the A53 (1.2GHz), with nearly double the cycle time. The optimizations I have made so far are as follows: Set the CPU to performance mode. Isolated CPUs: CPU0 is dedicated to running Linux services and the runtime itself, while CPU1 runs the EtherCAT task and the MainTask. Despite CPU1 only running these two tasks, the utilization still increases above 50%, which I find unreasonable. Additionally, I performed tests using cyclictest both without and with the runtime running. The performance is shown in the following image: From the results, I believe the CPU performance should be fine, but I am unsure why the monitoring results are not as expected. The testing outcomes should ideally be as close as possible to the cyclictest results. Does anyone have related solutions to this issue?

Post by breiter on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Hi, supporting a text based storage format is on our roadmap, see https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html It will be an Add-On feature called "File Based Storage" for the professional developer edition. Structured text POUs will be stored as plain text. Other graphical languages will remain in an xml format. You will be able to switch the storage type for projects. Certain workflows will become easier this way. Nevertheless restrictions will remain because of CODESYS specific storage logic (for example how methods below function blocks are stored as file). So merging using our Git Integration Add-On remains the recommended workflow. A workflow involving Visual Studio Code as the main IDE is not supported. Simply because many topics like library management, task configuration or fieldbus configurators are not available for VS Code. A PLC project is a lot more than just some ST POUs. Best Regards

Post by mainak on Opaque NodeId in the OPC UA server ^{CODESYS Forge talk (Post)}
Hello all, I am using the OPC UA server with my custom information model. I have used the communication manager to add my information model under my application and created instances from OPC UA types. I see that the created instances in the OPC UA server has some opaque nodeid (attached screenshot) and I want to change that. Therefore I have the following questions: 1. Is there a way to configure the NodeIds of instances in the OPC UA server? I tried to edit it using the UaExpert client but got error "BadNotWriteable". is it possible to configure it somewhere so that the nodeids can be changed using an external client? 2. Is there a way to define the rule for creating instance nodeids within the codesys IDE? 3. Is it possible to create the instances before e.g. using a modelling tool like UaModeler and import them as part of the information model and use them later? Using the communication manager, I can only create instances from types. I couldn't find a way to map my existing instances to plc tags from my application. It would be nice if someone could help me with these issues. Thanks in advance. :)

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Hi, Communication with the ADS1115 is actually simple. 1. write config 2. write address pointer 3. read conversation register The ADS1115 works like a multiplexer. This means that you do this individually for each channel that you want to read. e.g: Channel 1: write config > write address pointer > read conversation register Channel 2: write config > write address pointer > read conversation register Channel 3: write config > write address pointer > read conversation register Channel 4: write config > write address pointer > read conversation register then you start again from the beginning You can also omit individual channels or read only one. It doesn't matter. I have written the driver so that I can also use it on the TCA9548. The driver is from Stefan Dreyer. In your case, the driver works and communication with the ADS1115 is running. As you can see, the cfgWrong:=FALSE If you could not write or read data, cfgWrong:=TRUE; This means that either something is wrong with your ADS1115 or you have connected something incorrectly. Question: what voltage do you want to measure?

Post by jackbrady on Function Blocks and arrays of function blocks ^{CODESYS Forge talk (Post)}
Hello, I am new to Codesys and PLC programming in general (please go easy ha!) I'm not looking for code to be written for me just some help and pointing in the right direction. I am writing some code to send commands to a relay based on input values (to put it simply). Quite basic stuff. I have wrote a function block that takes a global variable (Open_command:BOOL) and outputs to another global variable (Opened : BOOL). The function block is simulating a device so I'll eventually get the globals from that. I now need to create multiple versions of this function block/ device (lets say 100) but I need each iteration of that function block to reference it's own relevant global variable. I think that the best way of doing this would be to use arrays, although I could be wrong. I am aware that for up to 100 instances I could very well manually assign everything but that seems rather time consuming and I want a fancier way of doing it. Here is a very basic example of what I am looking to do, please note I have not written this in proper code it's just to show what I mean. Global Variables V[0-100] int Open_command [0-100] Bool Opened [0-100] Bool Function Block var input x : BOOL Var output y : BOOL if x then y = TRUE ELSE y = FALSE The input to my function block will be Open_command, output will be Opened Example code. If V[x] > 10 then Open_command [x] = TRUE ELSE Open_command [x] = FALSE (So when V1 goes above 10 I need Open_command1 = TRUE therefore initiating FB1 output. V2 > 10, open_command2 = True > FB2 output V3 > 10, open_command3 = True > FB3 output ... ... ) What I can't seem to figure out is how to tie all this together, I have read through the codesys documentation and if anything it has confused me more! ha. Apologies for the poorly written post but hopefully you understand what I am trying to get at. Thanks, Jack

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!

Post by thommy54 on Lizenz wiederherstellen SP20 ^{CODESYS Forge talk (Post)}
Hallo Edwin, ich bräuchte mal eine schnelle Hilfe. ich testete einen zweiten Raspberry Pi 4 mit meinem Lizenzdongle eines laufenden Raspberry. Der 2. Raspberry ist als Redundanzlösung bei einem Crash gedacht. DIe Schwierigkeiten begannen, als ich mit dem Raspberry 4 V1.5 nicht mehr mit SP16 weiterarbeiten konnte. Ich updatede auf SP20.1. und die Schwerstarbeit begann. Das Image wurde rübergeschoben und alles auf dem zweiten Rechner soweit zum Laufen gebracht. Der Dongle wurde ebenfalls am 2. Rechner eingesteckt. Ob er überhaupt wirkte, kann ich nicht sagen, da für diesen Testfall Codesys so oft rauf und runter gefahren wurde, das die 2h-Grenze kaum erreicht wurde. Problem: Beim Zurückstecken des Dongles in den ursprücnglichen Rechner ist alles an Lizenzen weg. Der Lizenzmanager hat keinen Container mehr und der Befehl "lsusb" bringt nichts zurück. ich war der Meinung, das der Dongle genau für diesen Zweck gedacht war - die Lizenz von einem Rechner zum anderen mitzunehmen. Liege ich da falsch ? Wie komme ich nun wieder zu einem funktionfähigen Dongle ?? Weitere Versuche unternahm ich mit dem Wiederherstellen des Dongels. Dabei steckte ich ihn in meinen PC (Workstation) und siehe da, es werden noch 3 von ehemals (2020) 6 Lizenzzeilen angezeigt: (siehe Bild Problem_Lizenzen_Raspberry.jpg) Dann versuchte ich das Wiederherstellen über eine Lizenzaktualisierungsdatei vom Lizenzserver. Da kommt aber eine Datei mit anderem Dateityp (..WibuCmRaC) als im Lizenzmanager gesucht (WibuCmRaU). Die Datei ist dem Lizenzmanager auch nicht genehm (Bild Problem_Lizenzen_Raspberry_2.jpg). Nun steht Codesys auf besagtem Raspberry alle 2h still. Das soll die Lizenz doch verhindern. Angeblich soll seit SP13 auch kein eigenes Backup mehr nötig sein. Bis zum Erhalt des nicht brauchbaren Linzenzfiles hat da sja geklappt. Ich kann auch im Lizenzmanager keinen Punkt "Lizenz wiederherstellen" finden. Hat sich da mit SP20 etwas geändert? Wenn ich mir eine neue Lizenz hole - wie bringe ich sie auf den Dongle (der ja jetzt nicht "nagelneu" ist). Ich fürchte, das geht auch bloß schief. Im Voraus vielen Dank Thomas

Post by mgabryel on Problems with CAN 2.0 comunication on Wago PLC (Codesys 3.5) ^{CODESYS Forge talk (Post)}
Hello, I am trying to program CAN Bus comunication on WAGO PLC (more precisely on WAGO Touch Monitor model TP600). I am using for this purpose library "WagoAppCanLayer2" from Wago company. My IDE for programming this device is CODESYS V3.5 SP19 Patch 2 + (64-bit). My program is written in Structured text using function blocks from previously mentioned library. Here is code of this program: 1) Variables declarations: PROGRAM PLC_PRG VAR oOpenInterface : WagoAppCanLayer2.FbCanL2Open :=( udiBaudrate := 125000 ); xInterfaceIsOpen : BOOL; sInterfaceInfo : STRING; oReceive : WagoAppCanLayer2.FbCanRx29BitFrame :=( xBufferMode := FALSE, wCanId := 16#181 ); xRecv : BOOL; sReceiveInfo : STRING; oSend : WagoAppCanLayer2.FbCanTx29BitFrame :=( dwCanId := 16#100, //was 16#201 xRtrFrame := FALSE ); xSend : BOOL; sSendInfo : STRING; oCanDiag : WagoAppCanLayer2.FbCanErrorInfo; xRst : BOOL; aSendData : ARRAY [1..8] OF BYTE; bSendLen : BYTE; TON_0 : TON; TON_1 : TON; END_VAR 2) Program body: oOpenInterface( xEnable := NOT xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE ); sInterfaceInfo := oOpenInterface.oStatus.GetDescription(); xInterfaceIsOpen S= oOpenInterface.xValid AND NOT oOpenInterface.xError; oReceive( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xRxTrigger := xRecv ); sReceiveInfo := oReceive.oStatus.GetDescription(); IF NOT xRecv THEN IF oReceive.bRxNBytes > 0 THEN oReceive.aRxBuffer[1]; oReceive.aRxBuffer[2]; oReceive.aRxBuffer[3]; oReceive.aRxBuffer[4]; oReceive.aRxBuffer[5]; oReceive.aRxBuffer[6]; oReceive.aRxBuffer[7]; oReceive.aRxBuffer[8]; END_IF xRecv := TRUE; END_IF aSendData[1] := 224; aSendData[2] := 13; aSendData[3] := 14; aSendData[4] := 15; aSendData[5] := 222; aSendData[6] := 13; aSendData[7] := 14; aSendData[8] := 15; bSendLen := 8; TON_0(IN:= NOT TON_1.Q, PT:= T#2S , Q=>xSend, ET=> ); TON_1(IN:= TON_0.Q, PT:= T#2S , Q=>, ET=> ); oSend( xEnable := xInterfaceIsOpen, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, aTxBuffer := aSendData, bTxNBytes := bSendLen, xTxTrigger := xSend ); sSendInfo := oSend.oStatus.GetDescription(); oCanDiag( xEnable := TRUE, I_Port := IoConfig_Globals.WAGO_CAN_LAYER2_DEVICE, xTriggerResetCounter := xRst, xValid=> , xError=> , oStatus=> , wBusState=> , wBusDiag=> , uiRxOverflowsL2=> , uiTxOverflowsL2=> , uiRxOverflows=> , uiMsgTimeouts=> , uiBusOffs=> , uiBusWarnings=> ); Program first opens comunication on CAN 2 device and then periodically try send one CAN data frame. After starting program CAN 2 interface is properly open. The xSend variable is toggling with period 2s. When program sends data an "Tx overflow" error appears. When I am watching CAN_H line on DSub 9 socket i am not able to see proper CAN frames - see screenshot attached to this message. Could somebody help me determine what is wrong with this program. Best regards

Post by thn-power on Updating OPC UA Core Nodeset on PLS ^{CODESYS Forge talk (Post)}
Hi After much trail and error I think I found the root cause to my OPC UA problem. The problem is that I cannot manage to build and download a program with a a custom OPC UA Information model. We use a Weidmueller WL2000 PLS, but the problem also exsist on the Win V3 PLC. Our custom information model is based on the latest versions of the OPC UA Core Nodeset v 1.05.03 (2023-09-20) and UA/DI nodeset 1.04.0 (2022-11-03) Those nodesets are installed in the Codesys Information Model Repository (3.5.19.6) However, when trying to build I get the following error. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/ is required by http://bos.org/ with a minimal publication date from 15.12.2023 but the device has only a model from 15.09.2021 installed. Probably the information model from 15.09.2021 is missing in the information model repository. [ERROR] Untitled1: Communication Manager [Device: PLC Logic: Application]: The information model http://opcfoundation.org/UA/DI/ is required by http://bos.org/ with a minimal publication date from 03.11.2022 but the device has only a model from 09.03.2021 installed. Probably the information model from 09.03.2021 is missing in the information model repository. Build complete -- 2 errors, 1 warnings : No download possible I think the problem is that the UA Core nodeset is implemented in the PLC firmware (at least that in Siemens S7), and that only includes the "old" nodeset from 2021-09-21 etc. So the question is, how (or if?) can I transfer the new nodeset to the PLS? I have created separate Information models under Communication manager with the newer code nodesets (UA and DI). But it seems that the compiler does not recognize them being excising, neither in the Codesys IDE or on the PLC. Would have guessed that this is a common issue, sine many manufacturers use the latest versions of the OPC UA standard, and that it would be a solution to the problem.

Crafting my Fellowship Personal Statement was like weaving the threads of my aspirations into a tapestry of words. Each sentence became a brushstroke, painting a vivid portrait of my journey and ambitions. Beyond being just a document, it became a mirror reflecting the depth of my experiences. Like a conductor guiding an orchestra, my personal statement was composed to resonate with my unique voice. In the realm of specialized opportunities, this statement serves as a compass, guiding me toward the next chapter of my professional growth. With each word, I felt the guidance of mentors shaping my story into an eloquent narrative.

Post by janderson on OPC UA Server limitations, large array crashes runtime ^{CODESYS Forge talk (Post)}
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!
