Post by alexgooi on No Bootproject possible ^{CODESYS Forge talk (Post)}
Hello Simon, Thank you for your response. The problem occurs after about 10 online changes, after this a full download is required, but that means that the installation is going down. Is it possible to enlarge the space reserved for online changes, so that the problem occurs after 100 online changes for example? Kind regards Alex

Ok, I think I understand. The problem is my language-setting being "swedish". I will check if I can switch to english. Update/confirmed. Change LANG to en_GB, this enabled the architechture to be correct and the control SL again to appear and to be possible to be updated. Thanks!

Post by rcaponi on Codesys Control RTE V3. Remote Control ^{CODESYS Forge talk (Post)}
Hello, I would like to have, if possible, some clarification on this function. That is, I would like to understand if it is useful for managing, fom my development PC, the RTE runtime executed on a remote control. This is what the help says: Remote PLC: Opens the Remote Configuration dialog. By enabling or disabling the Control remote PC, not local option, you determine whether a PLC is used that is on a remote or local PC. Accordingly, the menu commands Start PLC, Stop PLC, and PLC Configuration refer to the local PC or a PC reached on the network. For the remote PC, specify the Target PC address, Port number, and a Timeout value (in ms) for the connection (Remote Timeout [ms]). But does this mean that I also need to install the RTE runtime on my development PC? Is it possible to have some more information? Best regards Roberto Caponi

Post by latassan on RaspberryPi 5 gateway problem ^{CODESYS Forge talk (Post)}
Hello, I'm trying to use a raspberryPi 5 as a PLC. I fixed its IP address, I can ping it. I've also installed the CODESYS Control for Raspberry Pi 64 SL runtime on it. So I've created a gateway (IP address of the Raspberry, TCP port 1217). I see the green dot next to this gateway. When I do a network scan, I can see my raspberry (see photo). When I try to connect to it, I have to define an administrator profile, which I do. On validation, I see a message: No device is responding to the scan request. I've checked that port 1217 is listening on the raspberry, I've uninstalled the runtime then installed it again, but I can't connect. Also, when I try to configure the user groups before connecting, I see that Offline mode is not supported by the device, even though I'm connected to it in the Deploy Control SL tab. When I try to refresh, I see: Gateway not configured properly. How can I connect to my Raspberry? Have I defined my gateway incorrectly?

Post by timvh on License problem gateway ^{CODESYS Forge talk (Post)}
What we are trying to explain is that, yes CODESYS creates the software, but Epis decides how they implement it on their hardware, which runtime version they use and they decide which functionality they support. So it is always a combination of the two. What CODESYS provides is a runtime with options for e.g. visualization or softmotion. Epis could add this softmotion license as default to their controller, but if they don't then CODESYS provides another option with a single license in a "Wibu CodeMeter" container. Eventhough the feature exists, Epis has to add this "CodeMeter" software on their controller to be able to access the licenses in the container. We don't know if they did this. Then finally it depends on what type of runtime is on this controller and which license Epis is using. So if they have an OEM license (not an application based license), then most likely you will need the Softmotion license (not a number of axis). See https://store.codesys.com/en/codesys-softmotion-sl-bundle.html. But to be sure if this is supported by the Epis controller, you must ask Epis.

Hello, I am currently trying to use the AM243 LaunchPad as a PROFINET device and connect to it using CODESYS. In my setup I am also using a Raspberry Pi running the CODESYS PROFINET Runtime, which acts as the PROFINET controller. The setup of the Profinet controller is correct, so all devices are in the same subnet. However, I encounter an issue when scanning for PROFINET devices in CODESYS. The AM243 LaunchPad appears in the scan results, but the following error is reported: RPC Aborted: 0x16C9A049 Additionally, CODESYS shows the message that the identification data is not available and the IP address should be checked. Because of this error, the controller cannot establish a connection to the device. Another observation is that I cannot ping the AM243 LaunchPad from my PC, even though I configured what should be the correct IP address. Setup: PROFINET Device: AM243 LaunchPad PROFINET Stack: Industrial Communication SDK example PROFINET Controller: Raspberry Pi running CODESYS with PROFINET Runtime Engineering PC: CODESYS IDE Network: Ethernet connection between PC, Raspberry Pi, and AM243 In the attachments there is a screenshot of the corresponding error. Did anybody had the same error? Any hints or debugging suggestions would be greatly appreciated. Thank you!

Post by garyl on Comments in arrays and assigning RST coil's to 600 outputs ^{CODESYS Forge talk (Post)}
Hello all, im working on a project that requires me to convert an old automation direct DirectSoft PLC d2-250-1. One of the problems im encountering is that all of the comments are attached to members of the different addresses. When i convert the addresses (1777 "C" registers, 777 X registers, and 20,0000 V registers) im running into difficulties keeping the inputs/outputs correct since they are missing documentation. Is there a good way to retain the comments of the indexes in the array? Secondly, initially i was declaring the "C" and "V" addresses individually and this worked to retain the comments as to which register did what, however i ran into a problem when one rung reset (or set to 0) approximately 600 C Addresses. Since each tag is separately declared this proved to be nearly impossible without a literal wall of code that attempted to crash the program. So i converted all of the registers (C,X,Y,V) into separate structs, declared them as arrays and pointed all of the original call outs in the program to the newly defined structs. However i have now lost comments and the program is very hard to follow. Thanks for any help with this issue.

Post by tariq on Using Hilscher CIFX Cards as EtherCAT Masters in CODESYS ^{CODESYS Forge talk (Post)}
Dear Codesys Support Team, I hope this message finds you well. I am currently working on a project that involves using a Hilscher CIFX card to act as an EtherCAT master within the CODESYS environment. Despite following the available documentation and setup guides, I have encountered some challenges and require assistance to ensure proper configuration and operation. Questions: 1- Could you please confirm if the Hilscher CIFX card is supported as an EtherCAT master in CODESYS? If so, are there specific drivers or configuration files that need to be installed? 2- Are there detailed setup guides or example projects available that demonstrate the integration of Hilscher CIFX cards with CODESYS for EtherCAT communication? 3- Is there any additional software or plugins required for ensuring seamless communication between the CIFX card and the EtherCAT slaves within CODESYS? Your support and guidance on these matters would be greatly appreciated, as it is crucial for the success of our project. Thank you for your time and assistance. I look forward to your prompt response. Best regards, TB

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

Noob alert! I’m just getting my feet wet with CODESYS. I have a “Hello World” project in the CODESYS IDE. I’m using the Win SoftPLC on the same computer. I’ve added a Communication Manager under the Application node. Under that is “OPC UA Server -> IEC Symbol Publishing 01”. I also added “OPC_UA_Symbols -> Information Model”. I’m not sure I need the second thing. I was grasping at straws. I also set up several dummy symbols in the IEC Symbol Publishing 01 node. In my C# application, I am trying to get an instance of EndpointDescription from CoreClientUtils.SelectEndpoint(“opc.tcp://localhost:1217/Gateway-1”, useSecurity: false, 15000). I wasn’t sure about the “Gateway-1”. I found that in the CODESYS IDE under the project -> Communication Settings. When I execute the previous method call in C#, I get: “BadSecureChannelClosed”. I have no idea what that means. Any pointers to documentation are welcome.

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne

Post by bmatlove on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?

An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.

Post by gseidel on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
Hi SLUCodesys, dwErrorId is a drive specific error number. The drive documentation should be consulted to interpret it. (Note that you should use MC_ReadAxisError to read this error, see https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/MC_ReadAxisError.html. Accessing the internal variable will result in outdated values if the acis error is not mapped by PDO and is not recommended in general.) uiDriveInterfaceError holds errors of the SoftMotion driver for the drive. It is also an internal variable, not intended for direct access. It is intended for logging, the PLC log will contain the drive interface error, consisting of this number and an error text. My recommendation for handling axis errors in the CODESYS application: 1) Use MC_ReadStatus on the axis to find out whether it is in state Errorstop 2) If in Errorstop, there are two possibilities: an error reported by the drive (MC_ReadAxisError) or an error of the SoftMotion function blocks (output MC_ReadStatus.FBErrorOccured). 3) If there is no drive error, you can use SMC_ReadFBError https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/FBError/SMC_ReadFBError.html Best regards, Georg

In the IOMappingExample.project, I noticed that EtherCAT devices provide additional configuration tabs in the Device Editor, such as General, Process Data, etc. However, for custom I/O driver examples (based on IoDrv), the Device Editor only shows the default tabs like <devicename> I/O Mapping or <devicename> Parameters.</devicename></devicename> I’d like to create custom tabs or configuration pages in the Device Editor (e.g., “General Settings”, “Communication”, etc.) to allow users to configure parameters in a more structured way. Could anyone explain: How to define and register custom tabs or UI pages in the Device Editor? What tools or SDKs are needed to create UI elements such as combo boxes or check boxes? How to bind those UI controls to device parameters defined in the XML (device description)? Any example, SDK reference, or documentation link would be really helpful. Thanks in advance!

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.

Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, In our workshop we have a Lenze i950 servo drive that has an EtherCAT bus and CiA402 compatibility. The WAGO is PFC200 750-8212 and as per documentation it has built-in license for SoftMotion Light functionality. It is not capable of supporting the full SoftMotion functionality like gearing and synchronizing. I added the EtherCAT esi files from Lenze and the EtherCAT master does see the drive, then I added a SoftMotion Light Axis object. The problem is that I can only energize the axis, I cannot execute any other commands. I set the positive and negative torque limits from the PDOs to 200% and when I try to move the axis by force it does not move back to its original position. I use the SML function blocks from the PLCOpen library and the error from the function blocks is that the op mode cannot be changed. Then I tried using a standard SoftMotion axis object and everything works fine, except the MC_Home function block. The axis moves back to its position when forced out of it. I follow this guide from Lenze - Lenze i950 CODESYS V3 What could cause this issue with the SoftMotion Light axis object? Best Regards Konstantin Kolev
