M-bus on EibPC

[McKajVah]

Hi.

Does anybody know if it is possible to "connect" M-bus devices on the EibPC with an interface like this "http://www.a2s.pl/en/m-bus-10-p-3150.html"

Hey,

it should be possible to connect the EibPC to this device. It depends a little on the protocol of the device. As seen with the 1Wire Interface HA7E there is the possibility to write some code to read and write from and to the RS232 given. I have not seen any further protocol information so this should be examined prior to a purchase.

Regards,
Bernd

It would be surely connectable, but do you have some information on the RS232 Protocol of this device? In this case we can support your project.

I have requested information from the manufacturer. Will get back here when I know more.

This is the answer I got from them.

"Dear Kaj,

Our MBus10 converter is fully transparent so it will works correctly with every data format trnsmitting over RS232 and MBus.
It converts only hardware level signals beetwen RS232 and MBus so that every telegram from MBus is transmitted to RS232 and opposite.

If you have any questions please do not hesitate contact me.

I don't think I understand what they mean with "fully transparent"...

Any ideas?

I think this means that there is only a voltage-conversion needet...
The telegrams (content) are the same

Yes, that's my guess. So now, we need a MBUS Protokol. Do you know if there is any freely available?

It can be found on M-Bus

I haven't had time to look deeply into it, but I think all doumentation should be here.

Ok, I've checked it and it could be done - but not in a 5 Minute Job ... If you want to start, you will have my fully support, directly per my mail, if you want to. Just tell me, and I'll send you a PN.
