Post by scoob on ModbusFB - Slow Response Time ^{CODESYS Forge talk (Post)}
Hello, I have been trying to use the ModbusFB functions so I can put some code into libraries, but it seems to be very slow for me. I have a Modbus device with 100ms registers. I previously setup 10 channels in the 'traditional' Modbus Slave with channels and mappings - and set a cyclic trigger at 100ms - this worked fine. I then tried the ModbusFB example, and setup reading the same 10 blocks of modbus addresses, copying the example and putting all of the requests into an array and triggering the requests sequentially. I timed how long the requests are taking to get round to each one, and it is around 1s 450ms. How do I speed this up to match the cyclic time? IF NOT(init) THEN init := TRUE; // Set the required IP address: ipAddress[0] := 192; ipAddress[1] := 168; ipAddress[2] := 1; ipAddress[3] := 10; // Pass the required IP address to the clinet FB: client_NetworkSwitch.aIPaddr := ipAddress; client_NetworkSwitch.udiLogOptions := (ModbusFB.LoggingOptions.ClientConnectDisconnect OR ModbusFB.LoggingOptions.ClientReceivedValidReplies); // Try to connect the client client_NetworkSwitch(xConnect:=TRUE); // Configure all the channels to read connecting them to the client: portStatus_Request(rClient := client_NetworkSwitch, uiStartItem := 4096, uiQuantity := 32, pData := ADR(portStatus), udiReplyTimeout := udiReplyTimeout); portSpeed_Request(rClient := client_NetworkSwitch, uiStartItem := 4352, uiQuantity := 32, pData := ADR(portSpeed)); flowControl_Request(rClient := client_NetworkSwitch, uiStartItem := 4608, uiQuantity := 32, pData := ADR(flowControl)); linkUpCounter_Request(rClient := client_NetworkSwitch, uiStartItem := 5888, uiQuantity := 32, pData := ADR(linkUpCounter)); txPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8192, uiQuantity := 100, pData := ADR(txPacketCounter1)); txPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8292, uiQuantity := 28, pData := ADR(txPacketCounter2)); rxPacketCounter1_Request(rClient := client_NetworkSwitch, uiStartItem := 8448, uiQuantity := 100, pData := ADR(rxPacketCounter1)); rxPacketCounter2_Request(rClient := client_NetworkSwitch, uiStartItem := 8548, uiQuantity := 28, pData := ADR(rxPacketCounter2)); txErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8704, uiQuantity := 64, pData := ADR(txErrors)); rxErrors_Request(rClient := client_NetworkSwitch, uiStartItem := 8960, uiQuantity := 64, pData := ADR(rxErrors)); // Trigger all client requests initially FOR clientRequestsCnt := 0 TO (SIZEOF(clientRequests)/SIZEOF(clientRequests[0]))-1 DO pClientRequest := clientRequests[clientRequestsCnt]; pClientRequest^.xExecute := TRUE; END_FOR // Prepare sequential trigger / control of client requests. clientRequestsCnt := 0; pClientRequest := clientRequests[clientRequestsCnt]; END_IF // Call the client to do request processing: client_NetworkSwitch(); // Now we trigger client request sequentially ... IF NOT pClientRequest^.xExecute AND NOT pClientRequest^.xDone AND run AND client_NetworkSwitch.xConnected THEN pClientRequest^.xExecute := TRUE; END_IF // .. and check result/error IF pClientRequest^.xExecute AND run AND client_NetworkSwitch.xConnected THEN IF pClientRequest^.xDone THEN // Prepare next trigger of client request (a rising edge of xExecute) pClientRequest^.xExecute := FALSE; IF clientRequestsCnt < SIZEOF(clientRequests)/SIZEOF(clientRequests[0])-1 THEN // next client request clientRequestsCnt := clientRequestsCnt + 1; ELSE clientRequestsIterationCounter := clientRequestsIterationCounter + 1; clientRequestsCnt := 0; END_IF pClientRequest := clientRequests[clientRequestsCnt]; END_IF END_IF I did try a semi-coded way using the IoDrvModbusTCP library, and setting the slave com settings, then 10 commands and 10 requests, then using a TP on xDone as a pause, before triggering another request - this is time the delay is around 120ms - so the device is fine with the speed, just something I am doing wrong in the ModbusFB method I am sure.

Post by cdutz on Problems connecting to Codesys 4.9.0.0 runtime on my Wago PFC200 ^{CODESYS Forge talk (Post)}
Hi all. I am currently struggling to get my Wago PFC200 running the Codesys Runtime in version 4.9.0.0 working. I am using Codesys V3.5SP19. I updated the PFC200 to the firmware version 04.01.10(23) after having tried the latest version (04.03.03(25) from Wago and not being able to start the runtime. After reading version 23 was needed, I changed to that and at least was able to have it start the codesys runtime. I also installed the "Codesys Control for PFC200 SL 4.9.0.0" plugin for Codesys to install the Codesys runtime in version 4.9.0.0 as well as update the Gateway on the device. While I seem to be able to connect to the gateway on the PLC (the dot is green) and when doing a scan, I do now find my PFC200, which is a huge improvement to before, where with firmware version 25 it just failed to start the runtime and I never found any device when doing a scan. Unfortunately I don't seem to be able to connect to the PLC in codesys. I logged in via SSH and changed the password and I can see that this password is correct as the stuff in the Codesys PFC200 tools tab only works if I use my changed password. And I used those credentials to update the installed Runtime version, which the log claimed to have worked fine. Now whenever I try to connect to the device found in the scan, I get a authentication pop-up with empy device name, device address: 000A. As User I use "root" and as password the password that I changed it to. As a response I just get "Ungültige Benutzerauthentifizierung auf dem Gerät" (Eng. probably something like "Invalid user authentication on the device". What could I be doing wrong? Admittedly I'm a bit lost here :-/ Chris

Post by fmon on Modbus : dis- / re-connect cable: modbus does not re-start ^{CODESYS Forge talk (Post)}
Hello, I am using codesys Modbus TCP client (4.4.0.0) to communicate with a python modbus server (package pyModbusTCP). I first start my python server on the distant machine. After a fresh codesys compilation, a plc connection/transfer and a PLC run, the modbus connection is OK. Every time in this context the connection is created correctly. When I shut down the server, the modbus connection falls, that is normal. When I restart the python server, impossible to recreate the modbus connexion. With the client autoreconnection, I see on my server that the client tries to connect but unsuccesfully. I have the following message : DEBUG:pyModbusTCP.server:accept new connection from ClientInfo(address='192.168.1.20', port=33476) DEBUG:pyModbusTCP.server:Exception during request handling: NetworkError('recv return null') I tried to stop the codesys client and to restart it with these commands : Modbus_TCP_Client.xStop := True; // Or False Modbus_TCP_Client.Enable := True; // Or False Modbus_TCP_Server.Enable := True; // Or False I tried to confirm the error manually to force reconnection with: Modbus_TCP_Server_Motors.xConfirmError := TRUE; I tried also this command to STOP/RESET/START client and server (codesys side) but nothing happens : status_client := Modbus_TCP_Client.SetCommunicationState(eRequestedState := DED.DEVICE_TRANSITION_STATE.STOP); // .RESET & .START The answer of this function when executed is "status_client = NOT_SUPPORTED" It seems that is a socket problem, but I do not understand if it is on the client or server side. I tried a modbus simulator called "ananas.exe" and the result is the same. Impossible to get a modbus reconnection. What is different at the first connection and at a reconnection attempt ? Thanks for your help

Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Post by sturmghost on Visualization using methods and cyclic ST-calls ^{CODESYS Forge talk (Post)}
Im looking for a way to implement ST-code into the visualization element without creating a helper POU or method in my device/application tree. Like visualization properties are evaluated at each VISU_TASK cycle I want to be able to create own ST code which interacts with the visualization interface variables. To be more specific I want to have a property which executes user defined ST-code at each VISU_TASK cycle exactly like its already possible for Input Configuration on various mouse and dialog events. Also a property for initialization (so only executed once) and a timed property would be nice. With the situation right now I'll have to create a POU function which handles the ST-code and misuse a property, like the text variable, to execute this POU function at each VISU_TASK cycle. Or does it exist and I don't know it?

Post by captaincookie on increase default string length in queue ^{CODESYS Forge talk (Post)}
Hello, I'm using Codesys V3.5 SP18 Patch 4. In the ElementCollectionExample Project from Codesys, I test the SimpleQueueExample in a Control Win V3 x64 environment. I try to add a string of 95 characters length to a queue. The default length of strings is defined as 80 characters. In the initialization of a string variable, it is possible to increase the length by the definition of e.g. STRING(1000). But when I write the string defined like this to the queue, only 80 characters are written to it and the rest is missing. I think the default length is still set in the queue definition, so it is necessary to change this, isn't it? Is there any option to increase the default length of strings in the queue? Attached you can find the used project. Thanks in advance. If any information are missing or my description unclear please let me know.

As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

After some more digging I realized that I get an error on the PLC Logger saying PersistenceChannel: 150 (invalid type in data: SimpleLibrary). I suppose the issue could be found in the ConfigData, which is automatically generated and which looks like this: 1 9##83 SimpleLibrary#GVL.aMoreZeros.[1]#0#64512#15#0 <[2]#0#64520#15#0 <[3]#0#64528#15#0 <[4]#0#64536#15#0 <#0#64544#15#0 <[6]#0#64552#15#0 <<lrVar#0#64560#15#0 <strVar#0#64428#16#80 <uiDummy#0#64370#11#0 Perhaps the fact that the variable is stored within a library confused the compiler? I tried changing the PersistenceChannel parameters to xCompressTags := FALSE which changed the entry in the data file from _xCompressTags BOOL:TRUE _xCompressTags BOOL:FALSE but the actual content of the data file and also the config data did not change.

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 bjarne-pagaard on Communication between applications on same device/controller/runtime (Win RTE 3.5.20.20) ^{CODESYS Forge talk (Post)}
Thanks for this - I have now been looking in to just having an extra (non-RTE) runtime on the same machine, as you suggest. I will probably proceed this way. Even though it still seems very odd to me, that variable exchange to a different runtime is easier than between applications on the same controller. There will be some fun with the licensing, it seems. Does anyone know if it is possible to specify which license container/specific license the runtime is going to use at runtime. Let's say I have two available licenses with different resources available, for example one license allows multicore and multiple EtherCAT channels, but not many visu tags (for the RTE). Another with less resources but a lot of visu tags (for the Visu controller). Let's say the program in one of the controllers could be fully licensed by either of the two available licenses, but picks the 'largest' first. A bit later, the larger application starts, but is left with the smaller license.. How can I make sure that the 2 runtimes select the right license at startup?

Post by mubeta on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
CoDeSys 3.5.19.7 Target Berghof MX6 In a simple SoftMotion programme with two stepperless modular axes from CMZ, one is simply controlled in speed, but a spot must perform a positioning. I use the function MC_SetPosition() both to reference the axis at power-up and also to correct the actual position to a fixed machine reference detected with proximity. The function has only one instance and I actually use a booelan variable to control the ‘Execute’ input. Well, I cannot correctly change the axis position on the fly if it is running at high speed. The servomotor works in a speed range between 0°/s and 720°/s, (gearbox output with a 1:6 ratio). As long as the servomotor is operating at speeds below about 400 °/s, the function is able to correct the position correctly even when forcing values far apart, but at high speeds, from 400 °/s upwards, the correction no longer takes place. For example, trying to correct the position of 280° into 300° with absolute mode, the axis that is moving at speed actually shifts the position by a few degrees, not the expected 20. I don't understand why with the servo drive running slowly the position shift occurs correctly, while increasing in speed it no longer works.

Post by mattplc on OPC UA Codesys 3.5 Symbolkonfiguration VS Kommunikationsverwalter und Python/UA-Expert ^{CODESYS Forge talk (Post)}
Hallo, bisher war die Benutzung der Symbolkonfiguration für die OPC-UA Variablen recht easy einsetzbar. Im UAExpert Tool konnte man im Klarnamen den String sehen. var1 = client.get_node("ns=4;s=|var|WAGO 750-8212 PFC200 G2 2ETH RS.Application.PLC_PRG.fbTest.StateActual") Die Anbindung an die Python opcua Library hat so eigentlich gut funktioniert. Auch zum debuggen im UAExptert, konnte man den Value so sehen wie die Varibale heißt. In meinem Fall ein Enum. Was seit längerer Zeit nicht mehr funktionier ist das eingeben von Enums. Im UAExpert kommt die Fehlermeldung "BadTypeMismatch" früher war das nicht der Fall. Da die Symbolkonfiguration demnächst bei Codesys 3.5 rausfällt, wollte ich den Kommunikationsverwalter nutzen. Jetzt schaut der String mit der Node ID komplett anders aus. Bsp.: NS5|Opaque|0x01000000A6E12A718AF7333ABAFA2D7686EF27669CF33071C7D034759DE601779DF62178E9 Hier sieht man den Value gar nicht mehr im UA Expert. In Python finde ich auch keine Möglichkeit die OPC UA Variable einzulesen. Python: var1 = client.get_node("ns=5;s=|var|0x01000000A6E12A718AF7333ABAFA2D7686EF27669CF33071C7F016759BDC7114.PLC_PRG.fbTest.sVar_1") Weiß jemand wir das in Zukunft läuft? ich hab etwas das Gefühl, das die Übergeordneten Systeme die OPC UA Variablen nicht mehr so einfach einlesen können oder mache ich etwas falsch? Danke

Post by bertcom on STRING conversions to DWORD ^{CODESYS Forge talk (Post)}
Good afternoon. I want to communicate with a Domino Industrial Printer using its Codenet protocol. The printer wants a series of Hexadecimal characters with no spaces or '00' characters. Because of that i chose the option to make the prefix and subfix for my code in a string. I have variable data in another string. With a complete program of a lot of CONCAT functions i eventually get the format of code that the printer accepts ( tested it with the hercules tool). Hercules String : 1B4F513030311B7532626C61636B04 The problem is : Codesys adds automatically 'code' to the code to show it is a string. Codesys string : '1B4F513030311B7532626C61636B04' The printer does not understand this. My idea is to convert the string datatype to an LWORD. I have no idea how to do this. I random types in STRING_TO_DWORD, as return i get 0. That didn't worked. Also on internet the explenations around string converting in codesys are very limited. If there in anyone who can explain me how to do it, i would appreciate it a lot ! Thank you!

Post by egau on Enable and Disable Project IO programmatically ^{CODESYS Forge talk (Post)}
Hi @eschwellinger, I tried this with Modbus COM slaves. I was able to disable them (slave becomes greyed out in the device tree), but the DED.Reconfigure "eError" output shows "NOT_SUPPORTED". After this, when I tried to re-enable the slave, it did not work (device stayed greyed out in the device tree), and the DED.Reconfigure "eError" output also showed "NOT_SUPPORTED". Is there something to do about this, or the device just doesn't support reconfiguration? P.S: I tried this running locally on my computer (not in simulation mode). So of course I was not physically connected to the devices. I have two similar projects, but one of them doesn't have the Modbus_COM devices. I know I can "Exclude from build" the devices for that project, but I would really prefer not to do this if possible. I would prefer to dynamically toggle a configuration variable that would enable or disable the slaves.

Post by pistola on C0357: "GetNextClient" is obsolete, use VisuUtils instead ^{CODESYS Forge talk (Post)}
I'm having some troubles with this same issue and I'm wondering if someone can help me out. On a settings visual I allow the operator to enter some values however if they activate the page change button it will change the change with the Numpad dialog open. Since I'm using Visuelems.CURRENTVISU to change the pages I came across this code noted below for determining if the Numpad dialog was active. This code worked great however now in 3.5.19 it's now obsolete. I've tried following the directions in the attached program above however I can't see to get it to work in my program. Can anyone provide some help to determine if a dialog is open? FUNCTION Check_Dialog_Open : Bool VAR_INPUT sDialogName : STRING; // Input variable for the name of the dialog END_VAR VAR pstClientData : POINTER TO VisuElems.VisuStructClientData; // Pointer to the client data structure itfDialogManager : VisuElems.IDialogManager; // Interface for the dialog manager itfMyDialog : VisuElems.IVisualisationDialog; // Interface for the specific visualisation dialog END_VAR // Begin the iteration over the client manager VisuElems.g_ClientManager.BeginIteration(); // Loop through each client until no more clients are found WHILE (pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO // Get the dialog manager interface itfDialogManager := VisuElems.g_VisuManager.GetDialogManager(); // Get the specific dialog interface using the dialog name itfMyDialog := itfDialogManager.GetDialog(sDialogName); // Check if the dialog is open for the current client Check_Dialog_Open := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog, pstClientData, itfDialogManager); // If the dialog is open, exit the loop IF Check_Dialog_Open THEN EXIT; END_IF END_WHILE

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 timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

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 toby on Ethernet/IP communication with Omron NX1P2 ^{CODESYS Forge talk (Post)}
Hey guys, I'm very much a noob with networking, it's my achillies heel, and this is my first networking project using Ethernet/IP. Any help offered is GREATLY appreciated. I'm trying to network a Codesys Project with an Omron NX1P2 PLC. I'm using EIP due to hardware restrains. I've added the fieldbus, EIP scanner (as the master), and made a Network Variable List. On the Sysmac Studio end, I've made the variables and set them to network inputs/outputs, registered them in EIP settings, but when I try to set the target device (the Codesys project), I suspect I need to import an EDS file for the EIP mapping. Back in the Codesys project, I'm not sure how to: - Make an EDS file to share with Sysmac Studio - How to link the target device (Omron PLC) to the EIP fieldbus - How to map the inputs from the Omron PLC. Im sorry for my very open request for help, i'm kind of lost looking through the various forums/video/tutorials as many of them dont match what im trying to do. Any help, or sample programs would be so so greatly appreciated. If you need any further clarifications, please feel free to ask. Thanks in advance, Toby

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

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 caprez95 on Deleting the trend recording history ^{CODESYS Forge talk (Post)}
Hallo Ich möchte eine laufende Trendaufzeichnung stoppen, den Inhalt löschen und Trend-Diagramm auf 0 zurücksetzen. Laut Codesys soll das mit dem folgenden Code möglich sein: You can insert an input element in the visualization which the operator can use to delete the previous value recording in the trend visualization at runtime. The curve displayed until then is removed and the display starts over. In the application (example: in the program PLC_PRG), implement the following code: itfTrendRecording : ITrendRecording; itfTrendStorageWriter : ITrendStorageWriter; itfTrendStorageWriter3 : ITrendStorageWriter3; sTrendRecordingName : STRING := 'TrendRecording'; itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); xClearHistoryTrend: BOOL; IF xClearHistoryTrend THEN itfTrendRecording := GlobalInstances.g_TrendRecordingManager.FindTrendRecording(ADR(sTrendRecordingName)); IF itfTrendRecording <> 0 THEN itfTrendStorageWriter := itfTrendRecording.GetTrendStorageWriter(); IF __QUERYINTERFACE(itfTrendStorageWriter, itfTrendStorageWriter3) THEN itfTrendStorageWriter3.ClearHistory(); END_IF END_IF In the visualization of the trend recording, add a button for deleting the previous curve. Configure its Toggle property with the variable PLC_PRG.xClearHistoryTrend. ⇒ When xClearHistoryTrend is set to TRUE, the previously recorded curve is deleted. The recording immediately starts again. Dies löscht auch die Daten vom Trend, aber das Diagramm wird nicht auf 0 zurückgesetzt, sondern läuft einfach da weiter wo man gestoppt hat. Braucht es für den Diagramm-Reset noch einen zusätzlichen Befehl? Gruss

Post by greenwood on CODESYS Control Raspberry Pi mit Servotreiber T6 von StepperOnline ^{CODESYS Forge talk (Post)}
Hallo, ich versuche, eine Modbus-RTU-Kommunikation zwischen meinem Raspberry Pi mit CODESYS Control für Raspberry Pi 64 SL und einem Servotreiber von StepperOnline, Typ T6, herzustellen. Die Verbindung ist wie folgt: RJ45-Stecker am Servotreiber -> Kabel mit RJ45 an einem Ende und USB-A-Stecker am anderen Ende -> Seriell-zu-USB-Konverter -> Raspberry Pi. Der Seriell-zu-USB-Konverter und die Kabel habe ich zusammen mit dem Motor und Treiber von StepperOnline gekauft und sie sind dafür gedacht, den Servotreiber mit einem Computer zu verbinden, auf dem deren Setup-Software läuft. dmesg | grep tty auf dem Pi sagt mir, dass der USB-zu-Seriell-Konverter auf ttyusb0 ist. Ich weiß nicht, wie man das in einen COM-Port übersetzt, ich habe COM 1 genommen. Ich habe ein Projekt in Codesys erstellt und ein Modbus_COM-Gerät hinzugefügt, einen Modbus_Master_COM_Port und einen Modbus_Slave_COM_Port angehängt. Auf der Registerkarte "Allgemein" des Modbus_COM habe ich die folgenden Werte eingestellt: Slave address 1 Baud rate 9600 Parity None Data bits 8 Stop bits 2 Ich habe den Servotreiber auf die gleichen Werte eingestellt. (Ich habe auch andere Werte getestet, aber mit dem gleichen Ergebnis). Auf der Registerkarte "Modbus Slave Channel" des Modbus_Slave_COM_Port habe ich einen Kanal hinzugefügt und die folgenden Werte eingetragen: Access type Read Holding Registers (Function Code 3) Read Register offset 0x0000 Length 1 Ich habe noch keinen Code geschrieben, weil ich noch nicht herausgefunden habe, wie man die Kommunikation programmiert. Wenn ich das Projekt zum Raspberry Pi herunterlade scheint der Modbus_Master_COM_Port zu laufen (grünes Symbol), aber der Modbus_Slave_COM_Port nicht (rotes Dreiecksymbol). Wenn ich einen anderen COM-Port eintrage, haben sowohl der Master als auch der Slave das rote Dreiecksymbol. Ich habe dies auch mit meinem Windows-PC unter Verwendung von Codesys Control Win 64 versucht und die gleichen Ergebnisse bekommen. Ich wäre dankbar für jede Hilfe oder Tipps, wie ich den Grund dafür herausfinden kann, warum der Servotreiberreiber nicht reagiert.
