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 rossanoparis on Clarifications regarding the appropriate runtime system to use ^{CODESYS Forge talk (Post)}
Hallo all I would appreciate some clarifications regarding the appropriate runtime system to use. I've been using 'KUNBUS CPUs' and 'CODESYS Control for Raspberry Pi MC SL' for the last 4 years. Recently, there have been some changes in the CODESYS licensing policy. [ https://store.codesys.com/en/howto_applicationbasedlicenses ] My questions are mainly two: 1) If I need to start a new project using 'KUNBUS CPUs', which is the correct runtime system to use. 2) Old projects built using 'CODESYS Control for Raspberry Pi MC SL' should be updated to another RT system? Current RT systems ... a)CODESYS Control for Raspberry Pi MC SL b)CODESYS Control for Linux ARM SL c)CODESYS Virtual Control SL May I count on receiving an explanation to understand the differences among the runtime systems listed above? A detailed and well-organized answer would be greatly appreciated. Kind regards Rossano

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 dom4u on Using PEAK CAN PCIe card (IPEH-004040) with Codesys Control RTE V3 ^{CODESYS Forge talk (Post)}
Some findings on this issue: PEAK CAN Driver is the same as in every PCI card from PEAK. I updated the inf file. Here are my steps: 1. Include right VendorID into the *.inf file 2. Disable Windows driver check (Disable WHQL check). This you need because 3S driver is not certified. You will find steps via google or ask chatgpt :) 3. Select: Select driver from a list and navigate to the folder. Say yes to install an uncertified driver. 4. Driver installed and device without errors I did the same with CAN Card from ESD, but here you dont need to include the vendor ID. In ANY CASE it was not successful. The RTIOwdmgeneric is not available in Codesys or anyhow accassable :( I wonder that it fails in two cases, two suppliers, two driver in the same way. How can RTIOwdmgeneric implemented into the project?

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!

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?

Post by rene-h on ClientFilter used the same Client ID 2 times - Bug? ^{CODESYS Forge talk (Post)}
Hello, like the topic name says, i have a problem on one Visu which i cannot reproduce on another Visu. We filter buttons with input locks and visible items with [CURRENTCLIENTID] on different WebVisu's with different ID's, and one time the itfClient used the same Client ID for 2 Clients, so the Visualization on the first ID was wrong, because that one which connected after did not have the same permissions like the first, so the first one was blocked. We read the Clients with the VisuClientIteration project: //count active clients gCli.iNumberOfClients:=gCli.iNumberOfClients+1; // if client is active write data to global struct IF gCli.iNumberOfClients > 0 THEN gCli.astClientInfo[gCli.iNumberOfClients-1].iClientID:=itfClient.ClientId ; gCli.astClientInfo[gCli.iNumberOfClients-1].stCurrentVisu:=itfClient.CurrentVisuName; gCli.astClientInfo[gCli.iNumberOfClients-1].wsUserName:=itfClient.UserName; gCli.astClientInfo[gCli.iNumberOfClients-1].sIpAddress:=itfClient.GetIPv4Address(); gCli.astClientInfo[gCli.iNumberOfClients-1].ClientType:=itfClient.ClientType; END_IF Runtime from the device: 3.5.19.20 Codesys we use: 3.5.20.10 I added a screenshot where the same ID exists 2 times.

UC3100 comes with Arm Cortex-A8 1 GHz and belongs to Moxa Industrial Linux 1 (Debian 9) for Arm-based Computers. I tried to install the CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC. Unfortunately, the Third-party requirements: - libc >= 2.27 (required by CodeMeter Runtime) of the CODESYS Control for Linux ARM SL cannot be met on the Debian 9, which comes with glibc 2.24. I read the post by @johnlee (Getting Start with Codesys Control for Linux SL) (https://forge.codesys.com/forge/talk/Runtime/thread/0a515ced3f/). Where he discusses installation of CODESYS Control for Linux ARM SL on Debian 9. There was CODESYS Linux runtime v3.5.14 availble and it was successfully intalled on the Debian 9. However, the CODESYS Store has the oldest version V4.1.0.0 32 bit available. There is no way to find the CODESYS Linux runtime v3.5.14. So is there any work around for this? Or I cannot install the CODESYS Runtime on any of the Moxa IPCs based on the Moxa Industrial Linux 1 (Debian 9)?

Post by vahasa on CAN TPDO / RPDO ^{CODESYS Forge talk (Post)}
Hi I'm automation engineering student and I'm not yet quite familiar with CAN-bus. What I am trying to achieve, to send two byte message via CAN from Epec display to Scott Drive inverter. I'm using code template made with Epec Multitool in Codesys 3.5 Problem i'm facing is that drive responds with same COB-ID. In multitool, you can create TPDO/RPDO. And depending on that, display either sends or only receives. This is problem, because for parameter polling from drive, you need to send two byte request to 0x399 and drive responds with eight bytes. If request is longer, drive don't respond. 0x399 is currently setted as RPDO, so display doesn't send anything on startup and I made program that sends messages to 0x399 bytes 0 and 1 and bytes 3-7 are shown in display. If setted as TPDO, display send all eight bytes and therefor drive cannot respond. But, I think because they are defined as RPDO, display won't send message, although monitoring with Codesys, values are changed. Question is, how should COB-ID be configured in Codesys, so it wouldn't automatically start to send message but would send when needed?

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 manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

Post by acc00 on Main Task cycle too long leading to PLC Fail ^{CODESYS Forge talk (Post)}
I have 2 Wago PFC200 PLC, running with Runtime SP19 Patch 5, with the Redundant application. The PLC communicates as Modbus Master with at this moment 15 Modbus Slaves -later there will be 28 in total- (Drives, Power management units,...). These devices are connected in 2 rings (1 ring of Drives, 1 ring of Power Management units), with 2 Managed Moxa Switches being part of the ring. Each PLC is connected to one of these switches. The issue I'm encountering is that the Cycle time of the Active PLC goes very high when I'm closing the Drive ring (simulating an issue on one Cabinet supply, resulting in that one Drive shut down, which can happen on field quite often). As a result of this long cycle, the PLC fails and goes to Exception, and the Passive PLC does not take control of the system. A normal cycle is around 30ms for the Main task, and a few ms for the Ethercat task. When I monitor with Profiler, I see that in this Maximum Cycle, the main Task is only taking 13ms, so I'm not sure where the PLC is hanging for so long. Is the remaining cycle time the Redundant management/sync or something else? Thank you in advance.

When loading the program into S_PLC, a message appears stating that there is no connection to the S_PLC controller. Timeout error. Restart the controller, attempt to load, and see the above. After changing the cycle time for S_PLC to 50ms, the problem no longer occurs. My question, besides the difficulty of installation for a new user, is what causes the cycle time for S_PLC to be so long, and how can I fix it?

Post by nickpoon on SysProcessCreate stopped working after SP21? ^{CODESYS Forge talk (Post)}
I'm going through the process of updating the CODESYS Project a machine to 3.5 SP21 (old version was 3.5 SP20). One function that stopped working when upgrading was SysProcessCreate. I need to run a .exe file that is located in C:\Program Files\MQTTStream. Some initial searching suggested that there are new security rules that prevent the SoftPLC from reading/writing files to outside of its Device folder (located here - C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\24FD6770) Relocating files helped fix my JSON file reader/writer functions (which were failing previously), but not the case for SysProcessCreate. I've even attempted to just run window's cmd.exe and with: pszCommandLine = 'cd /d C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS\CODESYSControlWinV3x64\24FD6770\PlcLogic\MQTTStream & sift-proxy.exe --grpc_uri="https://grpc-api.siftstack.com" --api_key="xxxxxxxxxxxxxxxxxxx" mqtt-client --broker_ip=10.0.10.101 --broker_port=1883 --config_file="mqtt_telemetry_config.json" --username Plantd --password 1234 --stream_metrics --storage_path="sift-proxy-logs"' I have not been able to find a lot of documentation on this, and I suspect the new update may have created a bug for SysProcessCreate.

Hier mein bisheriger Fortschritt: Um nähere Informationen zu bekommen, habe ich einen strace erstellt: PID ermitteln: $ ps aux | grep codesyscontrol | grep -v grep --> 560 sudo strace -tt -f -p 560 -o /tmp/codesys_strace.log (Die Logdatei wird schnell einige hundert MB groß.) Mit grep -B 100 'si_signo=SIGABRT' /tmp/codesys_strace.log konnte ich die relevanten Einträge finden: (Die PID hat sich inzwischen wegen einem Reboot geändert) 1023 15:33:49.497136 writev(2, [{iov_base="Unexpected error 9 on netlink de"..., iov_len=45}], 1 <unfinished ...=""> .. 1023 15:33:49.498352 tgkill(545, 1023, SIGABRT <unfinished ...=""> 1023 15:33:49.498440 <... tgkill resumed> ) = 0 .. 1023 15:33:49.498730 --- SIGABRT {si_signo=SIGABRT, si_code=SI_TKILL, si_pid=545, si_uid=0}</unfinished></unfinished> Der Codesys Log zeigt zu diesem Zeitpunkt: Exception: HANDLED EXCPT <excpt>NonContinuable</excpt> in CH_COMM_CYCLE Mit sudo lsof -p 545 habe ich die Anzahl der geöffneten Dateien überprüft ohne Auffälligkeiten Mit sudo netstat -tunaep | grep codesys habe ich die offenen Netzwerkverbindungen der codesys Prozesse überprüft Hier sieht es so aus, dass codesyscontrol und codesysedge über die externen Netzwerkschnittstelle anstatt über den localhost kommunizieren: udp 0 0 172.19.11.127:1740 0.0.0.0: 0 17882 549/codesyscontrol. udp 0 0 172.19.11.255:1740 0.0.0.0: 0 17883 549/codesyscontrol. udp 0 0 172.19.11.255:1743 0.0.0.0: 0 16993 529/codesysedge.bin udp 0 0 172.19.11.127:1743 0.0.0.0: 0 16992 529/codesysedge.bin Leider kann ich keine Konfiguration mit einer anderen Schnittstelle einstellen..

Die Funktion pthread_setname_np() erhält einen EBADF-Fehler. Ich weiß leider nicht, ob das eine heiße Spur ist. Parallel dazu habe ich die Aufrufe von Systemfunktionen über SysProcess_Implementation.SysProcessExecuteCommand2 auskommentiert ohne den Fehler damit abzustellen. An diesem Punkt habe ich wegen Termindruck den alten Stand der Runtime (4.11.0.0) mit der Codesys Version 3.5 SP20 wiederhergestellt und die geänderten Programme und Visualisierungen manuell getauscht mit dem Ergebnis, dass der Fehler in den letzten 2 Stunden nicht mehr aufgetreten ist. Wenn jemand das Problem kennt, wäre ich für einen Austausch dankbar. Frohe Ostern!

Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');
