M-BUS MEdiA
In a standard configuration, an M-BUS
connection can be used to link up to 250* products with
a PC or PLC, over a range of 1000 metres**.
* depending on the M-BUS master
** depending on the number of products and the
communication speed
Recommendations
The use of a JYSTY Nx2x0.8 mm (0.5 mm²) unshielded
twisted pair is recommended.
If the range of 1000 m and/or the limit of 250 products
are exceeded, a repeater will need to be connected.
→
if the 250 limit is exceeded: only use the secon-
dary address.
M-BUS protocol
The M-BUS protocol operates using a master/slave
structure.
COUNTIS
(slave) units are compatible with both pri-
mary and secondary addressing modes.
Primary addressing can be configured via the product
interface. Secondary addressing uses a fixed, unique
address shown on the front face of the product (
a
).
M-BUS
COUNTIS
units also have the «Wildcard
addressing» function which allows products to be sear-
ched for on the M-BUS network.
Option to broadcast to addresses 254 and 255.
In addition, M-BUS
COUNTIS
units are OMS-
compatible (Open Metering Systems).
