B.7 M-Bus Metering
The Xenta 913 can be configured to communicate with an M-Bus serial
adaptor to allow meter monitoring through an I/NET or LON control
system.
A number of M-Bus Metered Values can be connected to a correspond-
ing set of LON Network Variables or I/Net Points to allow one or more
M-Bus meters to be monitored. The Xenta 913 is able to cooperate with
either a temporary or permanent M-Bus application master.
