Documentation not accesible #199

Closed Mk-arc closed 2 years ago

Hi,

i am pretty new to mbus. And the documentation website seems to not respond? Is there a mirror anywhere? visitng http://www.rscada.se/ just gives an error.

I got a cheap usb to mbus converter and hooked it up with an Relay PadPulse M2: https://www.relay.de/produkte/m-bus-slaves/padpuls-m2

When I try to run the scan I get following result:

./mbus-serial-scan -d /dev/ttyUSB0

How to get started with figuring out whats wrong?

Is it possible there are multiple M-Bus slaves connected with the same primary id? Did you tried scanning for secondary address?

Mk-arc commented 2 years ago

Hi @lategoodbye yes. It worked when I send data requests to address 254 and also set address worked and then the direct access without broadcast also worked fine. So I closed this issue.

Thanks!
