Hello, is here anybody who can help me, please? Thanks A Lot

Hallo together, i am working on some tests on linux ubuntu virtual, using openPowerlink stack 2.7. My powerlink connction works well, but with different features i have some issues. For my tests is necessary to use SDO over UDP. But the problem is on sending those packets. At first I send an payload of 23 bytes with function oplk_WriteObject, selecting kSdoTypeUdp, which returns 0x0 (No Error), but the packets are at 95% not sent. Sometimes are visible in wireshark just normal with source and destination...

Hi, thanks again. It is very dificult. I have no other possibility as get the data from powerlink over SPI, because this is an offical powerlink modul. So, where the data are stored on host application is clear, but how to use those data for openSAFETY? How to define at all incoming ant outcoming data on host application (is this some kind of array)? Is there any other example of this implementation available which is easiest? Thanks a lot for support. Best Regards

Hi, thanks for response. I am using https://www.anybus.com/products/embedded-index/anybus-compactcom-modules/m40-details/anybus-compactcom-m40-module---powerlink as a powerlink modul. Now i need to integrate the openSafety but i have no idea how to use the blackchannel and i dont know where to start with implementation. Can you somehow help me please? Best Regards Thanks

Hi Jannik, did you get to work the openSafety on 2 linux PCs? Or maybe someone else did implement openSafety over powerlink on 2 linux PCs? Thanks

Hi Guys, I have question about black channel of powerlink which is used for openSafety? What is it, how can we use him? Need to be something special implemented in order to use him? Or is already implemented in powerlink stack, and needs to be used just some defined index in objdict.h? Is maybe some documentation somewhere, because I could not find it? Can somebody explain a little bit about black channel? Thanks a lot!
