Hi, Thank you for your suggestion but the problem is fixed after I disabled and enabled the network adapter from Windows settings.

4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

CODESYS Forge

(Post)
Hi everyone, With the latest version of Codesys, itβs now possible to import DBC files directly into the J1939 Manager, which is great. However, Iβm trying to achieve the same thing programmatically and canβt find any scripting functions related to import_dbc or any host_parameter that would let me configure PGNs and signal mappings automatically. So far, Iβve managed to add the J1939 Manager and an ECU, and I can pass the DBC database to it, but Iβm 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.

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 msirotkin on EtherCAT status errors
CODESYS Forge

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

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/

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
