Post by fari on Configure J1939 I/O Mapping via Scripting ^{CODESYS Forge talk (Post)}
Hi everyone, With the latest version of Codesys, it’s now possible to import DBC files directly into the J1939 Manager, which is great. However, I’m trying to achieve the same thing programmatically and can’t find any scripting functions related to import_dbc or any host_parameter that would let me configure PGNs and signal mappings automatically. So far, I’ve managed to add the J1939 Manager and an ECU, and I can pass the DBC database to it, but I’m stuck when it comes to adding the signals. Has anyone figured out if this can be done through scripting? (Attached is an illustration of what I am trying to accomplish programmatically). Thanks in advance.

runtime could always be in latest version. just keep everything in CODESYS stable and deploy the latest runtime. This will work.

Post by wchin on Passing EtheNetIP adapter device into a Function Block to access it's IO ^{CODESYS Forge talk (Post)}
We are creating helper function blocks for our VFD(EtherNetIP). How should I set it up so that I can pass the device into and out of the Function Block so that ideally I can access the IO of the device by devicename.channelname. So something like for example we have a VFD with a start bit that is in the ControlWord channel and a SetVelocity that is a channel. And we want to create a Function Block called StartVFD. So I declare something like: FUNCTION_BLOCK StartVFD VAR_IN_OUT device: ioDrvEthernetIP.RemoteAdapter; END_VAR VAR_INPUT velocity : REAL; So in the code it would look something like device.SetVelocity := velocity; device.ControlWord.6 := True; We have a pretty basic eds file for our VFD and can update it if necessary. Thanks in advance.

Post by miltos on licensing question ^{CODESYS Forge talk (Post)}
Greetings to all, I'm working on a webvisu project on control win V3 x64 runtime, and have purchased 3 licenses for my application. -Codesys Control Standard M -Codesys Visualization L -Codesys Communication M I have them installed on a Codesys usb dongle When I try to download the program, a login error window appears with the message "No valid license found for the webvisualization". The control win v3 communicates with 3 plc, and have enabled communication over codesys V3 communication by adding one datasource for every plc in the datamanager. If I remove the data manager from the project, the rest of the visualisation can be downloaded normally. Do I need to purchase another License and which one? Please find attached the software metrics and the error screen.

Post by msirotkin on EtherCAT status errors ^{CODESYS Forge talk (Post)}
Hello, I'm trying to understand the reason for the many errors on the EtherCAT master status page. If we set the cycletime to 1ms we see a lot of rxerrors and lostframes, but the send and recive times are quite good (see attachement). And the status of the EtherCAT bus is good (no other errors, all is green, slave has no errors) But when we set 2ms cycletime the lostframe errors are gone, but periodically increses rxerror counter (see attachement). The questions is, what do these errors actually mean and what we can do to get gid of them? Linux RT, imx8, Codesys runtime for ARM 3.5.21.10, Ethercat 4.10 Thanks

Post by imdatatas on Error: C0138: No matching 'FB_Init' method found for instantiation of VisuClientObjectMgr ^{CODESYS Forge talk (Post)}
Unfortunately, the "C0138: No matching 'FB_Init" method found" error is a nightmare for CODESYS V3.5 SP21. I'm not sure if anything has been done about this or if anything will be fixed. I've encountered the same issue many times, and it was only resolved by completely uninstalling SP21, deleting all related files and folders from my computer, and then installing SP19. So, I've given up on using SP21 and switched back to SP19patch7. Here are some previous posts regarding the "C0138: No matching 'FB_Init" on SP21 of Codesys. https://forge.codesys.com/forge/talk/Visualization/thread/0763d6ca8e/ https://forge.codesys.com/forge/talk/Motion/thread/9074005bf4/

Post by tali on Configuration of disabled/deactivated visu elements ^{CODESYS Forge talk (Post)}
would be great to have such fucntionality. Sometimes it is not clear for user which elemetns are blocked and which are not - the greyed out eleemtns are not so different for low resolution / low quality screeens. What I have in my mind as well is to have a possibility to detect the visu Element clicked on and get its Access Rights. If it is blocked/deactivated, the dialog can be rised with INFO 'please login first with proper rights'. It is possible now to have a Mose event Handler ( Examples -> EventHandler) and rise the dialog out of ST (Exapmpals -> ST Dialogs). I am struggling still with getting the separate Visu Element under the mouse and its structure info

Good afternoon Please help with localizing the error. Periodically, but on the same time grid, the error SysEthernet: packet could not be sent occurs. PLC and motors from XINJE. PLC — XSA-330L, rev. 1.2, drivers — DC5C2 (rev.5) In the task configurator, all tasks are set to simple numbers (11, 13, 41 ms) for convenience. The jitter for EtherCat and SoftMotion tasks is less than the task cycle (2 ms jitter for a 6 ms task). The power supply is sufficient for both the PLC and the motors. The cables are in good condition. Please suggest where to look for the problem. P.S. The PLC uses proprietary Linux and there is no SSH access.
