I don't understant why I'm not able to write a new value (ex: 0.0.22.0.0.255) for HDLC destination address in cosem objects 0.0.25.9.0.255 and 0.4.25.9.0.255. There is no problem when we set an IPV6 address with service=Tcp.
The meter response says "Hardware fault" :
Hi,
Hi,
The content of the data seems correct. You need to ask the meter manufacturer what they are expecting and is the meter supporting HDLC push messages.
