Mbus - Christopher - 18.08.2023
Hi.
I'm trying to poll some carlo gawazzi meters an have tried everything (i think) but are nok able to get a respone from them.
I'm using this script and have tried to change the baud rate and duplex.
I have tried to scan for 254 elements,
Code:
require('mbus')
mbus.init('/dev/RS232', 2400)
res, err = mbus.scan( 0, 10, 5)
log(res)
log(err)I have also tried to check my connections on the Rx/Tx both on LM5 and the meters.
But still I only got these responses:
Code:
m-bus 18.08.2023 12:45:44
* table:
m-bus 18.08.2023 12:45:44
* nilHW: LM5 Lite + Ext (i.MX6)
SW: 20230607
I there something I'm missing out?

You need an external Mbus to RS232 or RS485 converter.

"You need an external Mbus to RS232 or RS485 converter. "
Do you got any examples of a converter like this?

We've used these converters: http://www.techbase.eu/en/products/mbus-converters.html

Hi Admin,
I take this opportunity to ask you about the integration of M-BUS Engelmann heater meter using Techbase interface.
Is enough simply to know that the meter is M-bus or shall it has some technical features?
Thanks.

I have already read it. So the only important data is knowing the baud rate of the meter and the type of communication (rs232 or 485).
Thanks.
