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 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 dominggus on FileDialog - OnDialogClosed not called anymore ^{CODESYS Forge talk (Post)}
Hi, since the latest update it seems the OnDialogClosed is not called anymore?? using CODESYS SP20 Patch 3 with CODESYS Visualization 4.6.0.0 I am using LoadWriteRecipe to load a recipe file from disk (with some custom dialog settings), and I need to run a function (Recipes_LoadFromRecipeData()) afterwards which I execute when OnDialogClosed is closed with OK button. See attached screenshot and code below: *** OnDialogClosed : Recipes_OnLoadFileDialogClosed(pClientData): *** // the DialogManager is provided via the implicitly available VisuManager dialogMan := VisuElems.g_VisuManager.GetDialogManager(); IF dialogMan <> 0 AND pClientData <> 0 THEN FileOpenCloseDialog := dialogMan.GetDialog('VisuDialogs.FileOpenSave'); // gets the FileOpenSave dialog IF FileOpenCloseDialog <> 0 THEN result := FileOpenCloseDialog.GetResult(); // gets the result (OK, Cancel) of the dialog IF result = VisuElems.Visu_DialogResult.OK THEN Recipes_LoadFromRecipeData(); END_IF END_IF END_IF *** OnMouseClick: Execute ST-Code *** // override FileOpenSave Dialog settings // Visu_FbFileListProvider.Initialize(stDirectory, stFilter, stFileIn, stTitle, iRowCount, bBrowseDirectory, bTouch) VisuDialogs.g_FileListProvider.Initialize('./', '*.bunkerrecipe', '', 'Load recipe', 20, TRUE, FALSE); VisuDialogs.g_FileListProvider(); This used to work in CODESYS v3.5 SP20 Patch 1, but it seems it doesn't work anymore unfortunately? The OnDialogClosed just never seems to be called anymore....

Post by edvard-munch on How I can get "Done flag" for "Modbus Slave Channel"? ^{CODESYS Forge talk (Post)}
This is from 10 years ago, I know. But I have been using (SLAVE_DEVICE.iChannelIndex = CHANNEL_NUMBER) AND (SLAVE_DEVICE.xDone) I suppose that it shows xDone for the channel that shows up in the iChannelIndex at the same cycle? It seems to be working properly for two devices that I have been using it before But now I have another device and using two write channels, for one register each. One channel works properly and returns DONE flag When another channel is triggered, I see that it shows up in iChannelIndex, but flag DONE not received, but no Error for the channel. Also, when i check the register in the device it's evident that data has been transferred. Is this could happen sometimes with CODESYS, so DONE flag not received? Or this is a problem with a given device? With this certain register

Post by imdatatas on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, I have experienced such situations with some servo drive devices in the past. The home completion information is reported to the upper controller by the slave drive with the states of the relevant bits in the StatusWord (for example; 6041h Bit10, Bit12 in Home mode). If the states of these bits are correct in terms of number and state but the motor does not actually perform the action; You can contact the slave drive manufacturer. There may be a problem with the device firmware. Another area you can play around with is looking at the settings in the "Advanced configuration" for Softmotion axis on the page the link to below, and trying it out and using the one that works for you. https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_cmd_add_softmotion_cia402_axis.html A method I recommended worked for a user as in below message. https://forge.codesys.com/forge/talk/Engineering/thread/40bc82454d/ I hope your problem will be solved as soon as possible and by sharing the result here, you will help others to know and overcome it. Good luck. Best regards, Imdat

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

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Im looking for a way to define predefined version of the same structures through "extends"/inheritance. What I want to do is best shown with an example: TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE (* this/below is not possible as I understand from the compiler?? *) TYPE LOG_DATA_BOOL extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.BOOL_; END_STRUCT END_TYPE TYPE LOG_DATA_INT extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.INT_; END_STRUCT END_TYPE etc. for LOG_DATA_REAL and ..STRING. The system will not allow me to "re-define" "val_type" however. Instead I must do the work-around of defining four different types with all fields individually defined. The benefit if I could extend the base item would be that Im (more) sure the structures are identical. In usage I can call in a specific type rather use the base type and assign which type. Usage by pointer/ref to log_data_base would also be easier.. (* Usage: *) log_data : log_data_int := (name, value etc.) (* Instead of: *) log_data : log_data_base := (name, value, val_type).. Is this possible to achieve in some way that I have missed?

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 struccc on The future and proper use of CAA.BOLT, CAA.SEMA,.. ^{CODESYS Forge talk (Post)}
Dear All, Dear CODESYS, I'm curiously following CODESYS transitioning away from the CAA libraries, and I'm mostly in favor of these major changes. Naturally, I'd like to align my current (not end-user) developments accordingly. I'm tracking , reading release notes, ... And want to figure out the future :) Is it possible to hear / read more about the reasons, objectives and scope of these changes? One important element is CAA Types - CAA Types Extern. What is the plan with that? What's the future of CAA.SEMA, CAA.BOLT ? I have never used them (always relied on SysLib*), but they are tempting... Would be useful to have a platform independent "Macro" for this functionality... Is there something in existing or planned ? Are they suitable to be used in low level libraries... For Example IO-Drivers, Components, "to-become system libraries"? CAA.TaskLock, CAA.TaskUnlock ? Well, they don't claim platform independency, so I can't rely on those.... Any up-to-date advise, standard, pattern to follow in new libraries for task and resource locking? Practical set of conditional defines to be used? If this information is not publicly available, can you please send a private message about the proper way to achieve this? I have support agreement, just couldn't get trough with these questions...

Post by r-c-r on SM3RaspiStepper 0.0.0.6 issue ^{CODESYS Forge talk (Post)}
Ok, so i made some tests in the meantime and i have some conclusions. It apears that the enable bit is activated only when a motion function is executed. I implemented a very simple program with MC_Power and MC_Jog. If i enable everything on MC_Power, the enable GPIO pin stays off. However, as soon as the MC_Jog function is used the enable GPIO pin turns ON and remains ON. In version 0.0.0.4 this is not happening. The GPIO enable pin turns on or off when the MC_Power is enabled or disabled. From this behaviour i understand that in version 0.0.0.6 the GPIO enable bit is activated together with pulse and dir pins when motion starts. When motion stops, enable bit remains with the last state (on in this case) and you cannot turn it off for example. For me this bit is useful because i can turn on and off the stepper drive with MC_Power function. Now i can turn it on, but never off.

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 pernockham on AC Persistence - values are not read from file during start? ^{CODESYS Forge talk (Post)}
Im struggling with the AC Persistence. AC persistence seems to work for any variable that is changed online and values are kept during reboot. However, if I try to edit the persistence files offline or replace the persistence files with a previously downloaded older persistence file (with modified values), the online value will not follow, as if the system did not at all read the file at boot? My testing sequence. - Edit a the value of a persistenced variable (with xSaveOnChange = True) - Save/download the associated persistence file, (and confirm the value has changed). - Edit the value online for a second time . - Stop runtime - Replace (upload) the persistence file with my previously downloaded file . - Coldstart/Warmstart/Start runtime - Whatever Im trying the value of my persistence variable will always be equal to that of my second edit as if the file is not read/considered during boot. What am I doing wrong?

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

Post by nicetuxedo on Can not activate license on Raspberry pi ^{CODESYS Forge talk (Post)}
Hello everyone, I'm hoping for some assistance with a license activation issue: a software crash has left my license in a strange state. Here is the sequence of events: I purchased a new license for the Raspberry PI from the official CODESYS web store. I opened the CODESYS and started the online activation process using the ticket number I received. During the activation, the CODESYS software threw an exception and crashed. I was not able to see if the activation completed. After restarting CODESYS, I attempted to run the activation process again with the same ticket number. The License Manager now gives me an error stating that the ticket has already been activated/used. I am now stuck because my installation is not licensed, but the activation server believes my ticket has been consumed. Has anyone encountered this before? Is there a way to have the ticket status reset?

Post by spiessli on Softmotion axis to CANopen Maxon IDX drive ^{CODESYS Forge talk (Post)}
Thanks for the advise, indeed, this was somewhat, what my intention was. I tried around again with EDSes and DCFs, anyway. It appears that the DCFs end up in a subfolder in the attach device dialog. Astonishingly, when attaching the DCF version I get a device in the device tree, where I can add a SoftMotion axis, whereas when I attach the device not in the subfolder, then I cannot. Further astonishingly, when looking in the CANopen parameters in supported profiles, "402" is listed in the case of the DCF variant, whereas in the EDS variant "0" is shown. Comparing EDS and DCF files I cannot guess, where the difference is coming from. I cannot tell either why I have always attached the EDS variant and apparantly never the DCF variant. As I am not in the lab right now, I cannot test if the connection actually is working. Thanks again, spiessli

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...

But when I try the same setup on another PC(2), I get an error message: Error loading Python DLL: D:\SCRIPTING\3.5.16.40\python27.dll (error code 14001) My setup on both PC's is thus: 1. Downloaded and installed Python 2. Copied the folder with the scripting collection to C: (because of admin rights) 3. Placed my .library file in the same folder as the scripting collection Only difference is that Python is v3.12.0 on PC1 and v3.12.1 on PC2. I thought maybe it was something with Python, but then I have tried using the scripting collection from 3.5.16.1, and that seems to work. Just not for scripting collection 3.5.16.4. I also can't seem to find any scripting collections on newer versions of Codesys? (e.g. 3.5.19.10) Thanks in advance!

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
I am trying to implement a mechanism to send alarm SMS. For this, I have created an Alarm Class with a Notification Action which calls a POU. This POU implements IAlarmNotifiable making it selectable in the Alarm Class configuration. IAlarmNotifiable has an Execute method which is called by the alarm class. Now, I want to extract the alarm message of the triggered alarm. The Execute method comes with a VAR_INPUT itfAlarm: AlarmManager.IAlarm which supplies a method called GetMessage. The help text says: Returns the message text, that has been configured for the alarm. The result is a pointer to the buffer, where the message text is stored The type of the result is CharBufferPtr, and at some place I read that it can be interpreted as a pointer to string. But I cannot manage to extract the alarm message, all I get are numbers. I have tried the following: psAlarmText := itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^; sAlarmText := TO_STRING( itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^ ); So how do I get access to the alarm message as clear text? (In this case, "Larm 1")

When i do a cold restart, the profinet master becomes active again and the devices are found again. In the log i get Ethercat packet receive error: sysethernet. I am a little confused, there is no ethercat device in the device tree. I already set the send clock and the reduction ratio to higher values, but without result. Can codesys be configured, so that the communication re-establishes without doing the cold reset? This is very annoying and is causing a lot of prodution losses. regards Tim

I have set up a brandnew Beckhoff panel pc with a codesys control runtime V3. I configured it together with 2 profinet field devices: a 16in/16out IO module from Turck and an MTS linear encoder.
