Post by rabaggett on CODESYS control for Raspberry Pi 64 SL errors ^{CODESYS Forge talk (Post)}
Update: I started over. I saved progress at each step. all compiled zero errors, zero warnings. Pre-processor messages remain, but I can make progress. Until I try to re- load the project file in Codesys. Re-loaded files error as above when compiled, even though they compiled error-free immediately before saving. Is my installation borked? (Not easy to re-install due to IT madness...)

Hello all, Somebody try to run the CodeSys at RPi Zero 2W with external ETHx device? I need to more information how youi do it, what need to it, ...etc. It is interesting to use it together with EtherCat-interface. For example I had try to connect W5500 over SPI. The eth0 is present, but does not found any EtherCat IO-device. BR

Hello New W11 machine. I've tried installing and the 'Codesys installer' appeared, which basically failed. This was the exe from the Store. I've now tried installing with an old copy of SP17, which didn't try and use the Codesys installer, but has hung at the 'Install all packages added to the setup' stage. Has the exe been updated to use the Codesys installer? What is the installer? Do we think it'll work on w11? thanks, Paul

Post by martinlithlith on Mux I2C ^{CODESYS Forge talk (Post)}
Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

Post by arundara on Variable Sync Issue In Soft Plc Redundancy ^{CODESYS Forge talk (Post)}
Hello, I was trying to create a redundancy POC for our application where we read data from few modbus tcp devices. As there is a limitaion that modbus tcp device support only for single master device, we wanted to test how the variable sync happens in redundancy mode. For that i have used the redundancy sample code added a variable "b" under a condition. What i observed was while active controller is running, if passive controller is powerup, passive controller is able to sync all the data configured for redundacny. But after that the variable data which resided under a condition is not synching from active to passive controller. I have attached the image where i have highlighter the variable. Can some help me to understand how redundacny work in codesys soft plc and if there is a solution to sync variable which are under condition, please explain the same or suggestion to achieve the same. Hardware - Raspberry Pi (2 qty) Redundancy licence used - yes in both controllers. Codesys runtime - 4.9.0.0 Codesys software version - V3.5 SP19 if i have posted this question in wrong section, please do let me know in whcih section i have to post this question.

Post by dogulas on OPC UA C# client connecting to OPC UA CODESYS server ^{CODESYS Forge talk (Post)}
Ok, I have a simple test environment. From C#, using OPC UA, I can read DINTs, write DINTs, read Structs, but when I try to write a struct I get BadNotWritable. I am using Communication Manager, OPC UA Server, and IEC Symbol Publishing. I have a struct defined with one single DINT in it. The instance of the struct is in GVL. The struct is marked read/write in IEC Symbol Publishing. Any ideas? Pointers are welcome. public static async Task WriteStructA(byte[] structAData) { if (_session == null) throw new Exception("session is null"); // create a RequestHeader RequestHeader requestHeader = new RequestHeader { Timestamp = DateTime.UtcNow, TimeoutHint = 30000 // timeout in milliseconds }; // create an ExtensionObject to wrap the value to be written ExtensionObject extensionObject = new ExtensionObject( new ExpandedNodeId("GVL_StructA", 5), structAData ); // create a WriteValue object to hold the value to be written WriteValue writeValue = new WriteValue { NodeId = _structANodeId, AttributeId = Attributes.Value, Value = new DataValue(extensionObject) }; // put the WriteValue object into a WriteValueCollection object WriteValueCollection writeValueCollection = new WriteValueCollection() { writeValue }; // perform the write operation asynchronously WriteResponse writeResponse = await _session.WriteAsync( requestHeader, writeValueCollection, CancellationToken.None ); // check the result of the write operation if (writeResponse.Results[0] != StatusCodes.Good) throw new Exception("Write failed: " + writeResponse.Results[0]); }

Post by imdatatas on Auto Declare window disappears by itself in the Ladder editor ^{CODESYS Forge talk (Post)}
Hello Everyone, The "Auto Declare" window disappears by itself in the Ladder editor. For example, a new function block is wanted to be added to the Ladder editor. (For example; MC_Jog block and instance name will be fbMcJog). To do this, "Empty box with EN/ENO" is added to the ladder line from the Toolbox on the right and when you type MC_Jog in the empty box and press enter, normally the "Auto Declare" window appears and you are expected to be asked to write the instance name here. However, this "Auto Declare" window closes itself immediately, it does not wait for the user to enter a value or close the window. I often encounter this situation in many IDE versions. Does this seem like a bug? If anyone has encountered a similar problem while creating a new program name, function or function block instance name regarding the "Auto Declare" window and knows a solution, I would be glad if you could share it. Best wishes Imdat

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 aseitzinger on CODESYS Control for Linux SL on virtual machine? ^{CODESYS Forge talk (Post)}
Hello, there in different information available regarding the possibility to run CODESYS Control for Linux SL on a virtual machine. https://forge.codesys.com/trg/linux-sl/home/Home/ says CODESYS Control for Linux SL is a runtime system, which can run on any Debian based X86 PC, VM or Cloud container... https://store.codesys.com/media/n98_media_assets/files/2302000005/3/CODESYS%20Control%20for%20Linux%20SL_de.pdf says CODESYS Control for Linux SL can not be used on virtual hardware Currently I run the package mentioned on a virtualized debian machine running in PROXMOX Virtual Environment 7.4-17 and apart from huge jitter it runs without problems. The CODESYS key is passed as a USB defice to the VM. I wonder why there are different statements regarding the suitability in virtual machines and if the jitter would be reduced by installing CODESYS runtime on the host installing CDS runtime on the host and using a preemptive kernel (if available for the PROXMOX installation leaving CDS runtime where it is (on the virtualized debian machine) and install a preemptive kernel on the host and on the guest... Any advice is appreciated. Greets Arno

Post by edepalos on Text list from sd card ^{CODESYS Forge talk (Post)}
Hi guys, I have a textlist in my project which is working just as expected in a drop down list. I would like to move this text list to a sd card and access it from there, because I want to ease the editing of the contents of this textlist. I'm imagining a solution like the operator shuts down the plant, takes the sd card out, edits the textlist on the card with a windows machines notepad, then reinserts the card in the PLC and restarts the plant, having the new content of the textlist populating the dropdown list. I'm sorry that I'm asking you to spoonfeed me, but I did not find anything straightforward to do this... I saw in the Project>Project settings>Visualisation a relative path thingy, but I have the plant in operation and I would not like to make 100 trial and errors right now... I'm also not interested in SysLib file read commands and stuff, I would just like to access the file from the cards part, I don't want to replace its contents dynamically or such... nor I have language files or recipes... Thank You in advance! Br, Ede

Post by alex00 on DCS / Central Engineering with Codesys support ^{CODESYS Forge talk (Post)}
Hello together I'm currently investing in possibilities to have a central engineering software / system for Codesys based controllers. Something like a DCS / SCADA depending on where you see the functionality. We plan to use more or less vanilla codesys. The tool should support the following: - Connect to multiple PLC's in a project to see its variables and debug it. - Central Engineering capabilities (for example shared libraries in a project). - Download the new code / binaries to the plc. - Maybe have functionality to combine visualization elements and logic together. - See the live status variables on all the systems (crosscommunication). I see that codesys theoretically supports engineering of multiple PLC's, but I couldnt find to much functionality for a DCS type of operation, but that could be lack of knowledge. Any tips from you? Is Codesys good enough for this and maybe there are some manufacturers which build around it? Or are there good tools on the market with Codesys support (and the engineering is separate, but download to codesys possible). The use case is distributed energy installations like Heating pumps, Photovoltaics, etc. All these installations should have a PLC with codesys installed and run in one larger network, the PLC's are connected via VPN. Thanks for your inputs Greetings

Post by tama00 on GPIOs not running with Raspberry Pi 4 (and SPI connection) ^{CODESYS Forge talk (Post)}
Hello everyone, I have a working SPI connection (with transferExt) between a Raspberry master with Codesys and an ESP32 slave. I would also like to use a few GPIO pins. Is there a problem with using SPI AND GPIOs? Environment: Raspberry Pi 4+ with Raspian from Oct 23 Codesys V3.4 SP19 Patch 5 with Runtime Version 4.10.0.0 Device: GPIOs B+/Pi2 My problem: The status is displayed as “GPIOs : not running”. And also during mapping the message “The bus is not running. The values shown are perhaps not actual”. However, the variable changes that I make in my program are displayed under “Current Value”. In the Logic Analyzer, the pin toggles during transmission with small intervals of +-4us (seems to be a cyclical disorder, but I don't know where exactly it could be coming from). This applies to pins that I actually use (output) but also to the other GPIOs (not used). With GPIO 4, the line remains permanently high. Attached is a screenshot from the Logic Analyzer. Channel 1,3,5 were GPIO pin 26, 22, 17 Would be very grateful for help. Best regards

Post by george32 on Readable IO names ^{CODESYS Forge talk (Post)}
Hello Folks, I have a quite basic understanding of how PLC programming works. However I keep getting stuck on 1 problem I could not get my head around. The problem is as follow: I have a PLC with 60 IO (20 inputs, 40 outputs). Each IO is defined as a function block. Furthermore I have an external IO card connected trough a CanBus connection. This IO card has 4 analog input channels (USINT), 4 digital inputs (Bool) and 4, digital outputs (Bool) Because I have 2 different components which both has data have I made 4 arrays to store the data off every component in one variable. PLC_Input: Array [1..20] of BOOL; PLC_Output: Array [1..40] of BOOL IOCard_Input: Array [1..8] of BOOL IOCard_Output: Array [1..4] of BOOL Because the control and reading of the different in and outputs is done by a TCP connection I want to use some kind of enumeration or struct to give each index a name so that my main would be a little bit more readable instead of all the magic numbers. Also this would make my program more dynamic for the furter in case I need to changes some in the IO nummers. For example: pump is placed on the fysical terminal strip number place 54, which is the 3th output of the IO card in the program: if I am sending a message with value 54 I would like to control IOCard_Output[3]. If there is a solution or methode to get this done, I can eventually do the following in my main program: IOCard_Output[Pump]. I have tried the following: IOCard_Output[Pump - 51] with an enumration but this keeps raising an error I hope some of you could help me further with this problem. In gross lines: I want to couple all the different IO to a more readable name and this readable name should control the right Array index Thanks in advance, George

Post by rkohser on Scripted Git clone / checkout being blocked by "Project Environment" popup ^{CODESYS Forge talk (Post)}
Hi, I am trying to build a CI/CD pipeline around our codesys projects. The only entry point if the git url and branch, as we do not put our project file under source control, so we needed to find a way to git clone from the python scripting engine. This is currently how we do this : system.commands["Git", "Clone"].execute( "ProjectLocation=" + project_dir, "ProjectName=" + project_file_name, "RemoteUrl=" + project_git_remote_url, "GitProjectStoragePath=" + project_git_local_dir, ) system.commands["Git", "Checkout", "Branch"].execute( "PrimaryProjectHandle=0", "BranchName=origin/" + project_git_branch ) This works fine, except that, depending on the environment and the project, the "Project Environment" popup gets displayed to suggest for some updates, and waits for a user interaction, even with the "--noUI" flag injected as parameter. I investigated the VersionUpdateFlags, but the problem is that the git clone is an atomic operation that clones and directly opens the generated project without the possibility to inject any updateFlags argument (only used in the ScripProjects.open() function. I also tried to simulate some keyboard events acknowledge the window from script but I did not find the right location for the SendKeys statement, I think before the git clone call is too early and after is too late. So I am wondering if there would be some other way to do that. Is there some more proper scripting api for the git add on ? Is there a global configuration of the VersionUpdateFlags that would allow the popup to be disabled outside from any project context ? Is there some way to automatically acknowledge this kind of messages in a "--noUI" mode ? What do you suggest ? Thanks for your help, Roland Edit : I managed to solve my problem by following these steps in my pipeline : - create a template of a project and opt file preconfigured not to open the popup - open this project - initialize an empty git repo - add the remote, fetch and checkout the needed branch -> no popup is displayed, hourra Edit2 : The initial question was raised on a CODESYS V3.5 SP18 Patch 2 profile. Since CODESYS 3.5.19.30 a scripting API is available for Codesys Git that allows cloning a project with the support of VersionUpdateFlags https://content.helpme-codesys.com/en/CODESYS%20Git/_git_using_scripting.html

Post by timo on Visu: Angepasster Button mit Statusanzeige - welche Möglichkeiten gibt es? ^{CODESYS Forge talk (Post)}
Hallo, Ich gehe gerade Möglichkeiten durch, wie ich Buttons so erstellen kann, dass ich sie nachträglich möglichst einfach bearbeiten kann um z.B. die Farben des Aktiven/Inaktiven Zustandes darzustellen. Die Buttons bestehen aus einem Hintergrund als Farbverlauf, einem Text und einem Icon. Ich habe zuerst den ESC Image Button verwendet, aber auch hier müsste ich nacheinander alle Buttons bearbeiten, wenn ich z.B. die Hintergrundfarbe anpassen will. Jetzt habe ich die Buttons als einzelne Visualisierungen erstellt und in der Visu jeweils als Frames eingeblendet. Den Zustand kann ich dann durch unsichtbare Elemente in der Buttonvisu darstellen. Weil hinter jeder Buttonvisu ein Frame meines Hintergrundes liegt, kann ich die einfach anpassen. Siehe Bild- der Frame ist der graue Hintergrund, das Rechteck ist die Umrandung für den Status mit einer transparenten Füllfarbe. Gibt es da eine einfachere Möglichkeit die Elemente zu verknüpfen, sodass ich einen Button habe, den ich nachträglich möglichst einfach abändern kann? Bei den Buttons bei denen ich keine Icons einblende, kann ich direkt den Text auf den Hintergrundframe setzen. Wenn ich hier aber das farbige Randungsrechteck für den Status über das Frame liege, verdeckt es diesen natürlich. Gibt es eine Möglichkeit Elemente so einzublenden, dass dahinter liegende Elemente angeklickt werden können? Alternativ muss ich die Aktion auch noch mit dem überlagertem Element verknüfen.

Hi, We are working to provide our customers with CODESYS operation on our hardware product ( https://elprotech.com/product/el-qe-e-quantum-edge-series/ ). I'm trying to enable a CODESYS license (Soft container) on our product running ARM64 linux. This problem am having looks similar to here: https://forge.codesys.com/forge/talk/Runtime/thread/6d29b6b4de/ and here: https://forge.codesys.com/forge/talk/Runtime/thread/a2d0c63375/; but I am not running docker, and I am not re-installing a license. This is first time install. I have CODESYS Control SL running on my device, as well as CodeMeter. I purchased a license, and installed it to the CODESYS Development system, (Tools >> License Repository) then tried to install to the device (Tools >> License Manager >> o Device >> o Soft container >> Remote [0001] >> OK.

Post by clesio on CAA.File.Write – Unexpected characters when writing a CSV file ^{CODESYS Forge talk (Post)}
Hello everyone, I am trying to create a routine in CODESYS to export a report to a CSV file using the CAA.File library. The file is created successfully, but I am getting some unexpected/unknown characters in the generated CSV. The problem seems to be related to the SIZEOF() function. I am using it for the szSize parameter of File.Write, as recommended in the CODESYS documentation. However, when I use SIZEOF(), the CSV contains extra characters and parts of previous strings. I also tried using LEN(), but in my application the file is created empty, even though the string and the calculated length appear to be correct. Here is the relevant part of my code: PROGRAM Relatorio VAR // Bool b_Executa_fb_Cria_Arquivo : BOOL; b_Executa_fb_Fecha_Arquivo : BOOL; b_Escreve_dados : BOOL; b_Erro_fb_Escreve : BOOL; //STR s_Nome_Arquivo : STRING; s_Palavra : STRING; s_Palavra_Anterior : STRING; s_Data_Atualizada_Formatada : STRING; s_Dia : STRING; s_Mes : STRING; s_Ano : STRING; s_Hora_Atualizada_Formatada : STRING; s_Hora : STRING; s_Minu : STRING; s_Segu : STRING; //INT i_modo_fb_Cria_Arquivo : INT; i_ErroID_fb_Escreve : INT; //UINT i_Tamanho_Palavra : UINT; // Blocos de Funcao fb_Cria_Arquivo : FILE.Open; fb_Fecha_Arquivo : FILE.Close; fb_Escreve : FILE.Write; // DATA E HORA sc_DataTime : SysTimeRtc.RTS_SYSTIMEDATE; // STRUCT = sc uidResultRtcGet : UDINT; //stGetDate : SysTimeRtc.RTS_SYSTIMEDATE; uidResultConvertToDate : UDINT; uidResult : RTS_IEC_RESULT; END_VAR VAR_INPUT //BOOL b_SET_Executa_fb_Cria_Arquivo : BOOL; b_RES_Executa_fb_Cria_Arquivo : BOOL; b_Executa_fb_Escrita : BOOL; // INT i_Linhas_Cabecalho : INT; i_Linhas_Cabecalho_Anterior : INT; END_VAR // Para Testes s_Nome_Arquivo := 'relatorio/Teste1M.CSV'; i_modo_fb_Cria_Arquivo := 0; // TRATAMENTO DE DATOS DATA e HORA uidResultRtcGet := SysTimeRtcGet(uidResult); uidResultConvertToDate := SysTimeRtcConvertUtcToDate(dwTimestampUtc := uidResultRtcGet, pDate := sc_DataTime); // FORMATA DATA EM UMA STRING s_Dia := UINT_TO_STRING(sc_DataTime.wDay); s_Mes := UINT_TO_STRING(sc_DataTime.wMonth); s_Ano := UINT_TO_STRING(sc_DataTime.wYear); s_Data_Atualizada_Formatada := CONCAT(s_Dia, CONCAT('/', CONCAT(s_Mes, CONCAT('/', s_Ano)))); // FORMATA HORA EM UMA STRING s_Hora := UINT_TO_STRING(sc_DataTime.wHour); s_Minu := UINT_TO_STRING(sc_DataTime.wMinute); s_Segu := UINT_TO_STRING(sc_DataTime.wSecond); s_Hora_Atualizada_Formatada := CONCAT(s_Hora, CONCAT(':', CONCAT(s_Minu, CONCAT(':', s_Segu)))); // ABRE e CRIA ARQUIVO IF (b_SET_Executa_fb_Cria_Arquivo OR b_Executa_fb_Cria_Arquivo) AND NOT(b_RES_Executa_fb_Cria_Arquivo) THEN b_Executa_fb_Cria_Arquivo := TRUE; ELSE b_Executa_fb_Cria_Arquivo := FALSE; END_IF fb_Cria_Arquivo( xExecute := b_Executa_fb_Cria_Arquivo, sFileName := s_Nome_Arquivo, eFileMode := i_modo_fb_Cria_Arquivo, xExclusive := FALSE, ); //i_Tamanho_Palavra := SizeOf(s_Palavra); // ESCREVE NO ARQUIVO fb_Escreve( xExecute := b_Executa_fb_Escrita, hFile := fb_Cria_arquivo.hFile, szSize := SIZEOF(s_Palavra), pBuffer := ADR(s_palavra) ); // FECHA ARQUIVO fb_Fecha_Arquivo( xExecute := b_Executa_fb_Fecha_Arquivo, hFile := fb_Cria_arquivo.hFile ); IF Criacao_Edicao_Arquivos.b_Escreve_Cabecalho THEN CASE i_Linhas_Cabecalho OF 1 : s_palavra := 'ESTERILIZADOR'; 2: s_palavra := 'MAQ4; $R$L'; 3: s_palavra := CONCAT(CONCAT('CLIENTE: ',GVL.sReceitaAtual), '$R$L'); 4: s_palavra := CONCAT(CONCAT('NUMERO LOTE: ',DINT_TO_STRING(GVL.Lote)), '$R$L'); 5: s_palavra := CONCAT(CONCAT('OPERADOR: ', DINT_TO_STRING(GVL.Operador)), '$R$L'); 6: s_palavra := CONCAT(CONCAT('DATA: ', s_Data_Atualizada_Formatada), '$R$L'); 7: s_palavra := CONCAT(CONCAT('HORA: ', s_Hora_Atualizada_Formatada), '$R$L'); 8: s_palavra := '$R$L'; 9: s_palavra := 'PARAMETROS AJUSTADOS $R$L'; 10: s_palavra := CONCAT('TEMPO PRE COND.: ', CONCAT(INT_TO_STRING(GVL.rc_T_PreCondicionamento), ' min $R$L')); 11: s_palavra := CONCAT('PULSOS INERTIZACAO 1: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosInertizacao_1), ' PULSOS $R$L')); 12: s_palavra := CONCAT('PULSOS INERTIZACAO 2: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosInertizacao_2), ' PULSOS $R$L')); 13: s_palavra := CONCAT('PULSOS AERACAO: ', CONCAT(INT_TO_STRING(GVL.rc_PulsosAeracao_2), ' PULSOS $R$L')); 14: s_palavra := CONCAT('PRESSAO DE VACUO 1: ', CONCAT(REAL_TO_STRING(GVL.rc_PV1_max), ' bar $R$L')); 15: s_palavra := CONCAT('PRESSAO DE VACUO 2: ', CONCAT(REAL_TO_STRING(GVL.rc_PV2), ' bar $R$L')); 16: s_palavra := CONCAT('PRESSAO INERTIZACAO 1: ', CONCAT(REAL_TO_STRING(GVL.rc_PN1), ' bar $R$L')); 17: s_palavra := CONCAT('PRESSAO INERTIZACAO 2: ', CONCAT(REAL_TO_STRING(GVL.rc_PN2), ' bar $R$L')); 18: s_palavra := CONCAT('PRESSAO AERACAO: ', CONCAT(REAL_TO_STRING(GVL.rc_PAR), ' bar $R$L')); 19: s_palavra := CONCAT('PRESSAO ETO: ', CONCAT(REAL_TO_STRING(GVL.rc_PressaoETO), ' bar $R$L')); 20: s_palavra := CONCAT('PRESSAO Compl.: ', CONCAT(REAL_TO_STRING(GVL.rc_PressaoETO_2), ' bar $R$L')); 21: s_palavra := CONCAT('MASSA ETO: ', CONCAT(REAL_TO_STRING(GVL.rc_QuantidadeETO), ' Kg $R$L')); 22: s_palavra := CONCAT('TEMPO PRE COND.

Post by timvh on Device diagnosis ( EtherCAT IO card ) ^{CODESYS Forge talk (Post)}
You can get the state by just using the name of your node (same name as in device tree): VAR etcState: IoDrvEthercatDriverLib.ETC_SLAVE_STATE; END_VAR etcState := EJ1100.wState; Alternatively, you can iterate through the device tree to get the status of all (Ethercat) nodes. See here an example (no guarantee it works, just give as suggestion): PROGRAM P_IO_State VAR CONSTANT uiMAX_NR_OF_TERMINALS : UINT := 100; END_VAR VAR // general device diagnosis // can only be used when the Device - PLC Settings - Advanced settings - enable diagnosis for devices is enabled // this will add the DED library coupler: DED.INode; terminal: DED.INode; aDeviceState: ARRAY[0..uiMAX_NR_OF_TERMINALS - 1] OF DED.DEVICE_STATE; uiTerminalCount : UINT; uiIndex : UINT; // for each terminal check if it implements device diagnostics xQueryResult: BOOL; itfDevice : DED.IDevice2; xDiagAvailable: BOOL; eError: DED.ERROR; xEverythingOK: BOOL; END_VAR uiTerminalCount := 0; // start at the top of the device tree with the first EtherCAT coupler coupler := EtherCAT_Master.FirstChildNode; WHILE coupler <> 0 DO // for each coupler that is found start at the first terminal terminal := coupler.FirstChildNode; WHILE terminal <> 0 AND uiTerminalCount < uiMAX_NR_OF_TERMINALS - 1 DO // for each terminal that is found get the status through the device diagnosis interface xQueryResult := __QUERYINTERFACE(terminal, itfDevice); IF xQueryResult THEN aDeviceState[uiTerminalCount] := itfDevice.GetDeviceState(xDiagnosisInfoAvailable => xDiagAvailable, eError => eError); uiTerminalCount := uiTerminalCount + 1; END_IF terminal := terminal.NextSiblingNode; END_WHILE coupler := coupler.NextSiblingNode; END_WHILE uiIndex := 0; xEverythingOK := TRUE; WHILE uiIndex < uiTerminalCount DO IF aDeviceState[uiIndex] <> DED.DEVICE_STATE.RUNNING THEN xEverythingOK := FALSE; EXIT; END_IF uiIndex := uiIndex + 1; END_WHILE

Post by rmaas on Strange Behavior on Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, what you are seeing is not strange behavior. The problem is that everyting is happening in the same program cycle. After the variable Stepnumber is changed from 10 to 20 for example then you want the program to wait with the next EQ until the next program cycle. Else every EQ will be be true because in every line the variable Stepnumber is increased. When the program arrives (still in the same cycle) at the line with the timer, the Stepnumber has been increased to 30 in the meantime and the timer will allway be ON because even though the variable is written to 10 in this line in the next cycle it starts with 10 and will be 30 again before reaching the timer in line 8. Not very good at explaining stuff but i hope you get the problem. See screenshot below for an example of one way you could solve this...

Post by cer-wa on Not able to connect multiple profinet encoder in codesys Linux ARM64 ^{CODESYS Forge talk (Post)}
Hello, currently im working with a RevPi connect 5 on a codesys project. Up until now I was having a blast because things were going really smooth but for like almost a day im kind of stuck on the integration of multiple profinet sensors into my project. This is kind of a bummer because that should be an easy thing to do. What I tried so far was to create and additional ethernet adapter where I then tried to connect my devices. in the beginning I tried to connect the devices directly which was not working because I could assign the IP-adress only to the ethernet adapter and not to the devices but the device was found in the device repository (this gets important in the second part) So what I tried next was to setup a PN-Controller and connect my devices subsequently to the Controller. Sadly now the devices wont show up in the device repository anymore. To me its not clear why this is happening. And the worst thing is: I went ahead and setup a device completely like I would want to have it in the project and when I then click on scan devices I can even find the device. But it can not be added to project for whatever reason eventhough im 100% certain that the gsdml file is the correct one. Can anyone help me with this. Like I said this seems like an easy thing to do and its taking me way longer than expected already. The only thing that came to my mind why this might not work is because I have codesys license which only allows one profinet instance. Could that be the case? The error message seems then pretty unfit but ok. I will be grateful for every advice. Thanks in advance! Best regards!

Post by s1ack on Wago PFC200 Ethernet / IoDrvEthernet Issue? ^{CODESYS Forge talk (Post)}
CODESYS Control for PFC200 4.13.00 CODESYS IIoT Libraries SL 1.11.0.0 Application Based License: CODESYS Control Standard M I have (2) projects with similar code base and both using Wago PFC200. On the second project I am seeing 2 things that I have not been able to resolve: 1) Errors in the log under the Ethernet Item: IoDrvEthernet: [PCI\E1Q51CE62] Could not be found on target! Please check the Ethernet settings. 2) Exception for CPU Load. "Processorload watchdog: plcload=100, maxplcload=95" I have slowed down cyclic tasks on this project, even though on the first project there is actually more code - and it does not exhibit this behavior. In looking at the CPU loading via Linux 'TOP' command there appears to be 20% idle. So plenty of headroom (my opinion). In an effort to troubleshoot I have duplicated the target hardware on my bench. It ran overnight without a CPU load exception. On the test system, I have tried (3) version of the ethernet device. 3.5.16.0 3.5.17.0 and 4.2.0.0 Presently the log does not show the error, but status says the module reports an error. I really do not know if this issue is related to the CPU load exception. The issue does not appear to effect ethernet communications (ModbusTCP or SNMP or Webvisu or PuTTy into Linux Shell). On my test bench I have ModbusTCP slave simulators for all ModbusTCP slaves, but only (1) of the (5) SNMP devices present.
