LPB bus
Allocation of device and segment addresses:
The
L
P
B bus
organizes the connection of
several heat generators
and heating circuit controller
s by allocating distinct addresses to the
c
ascade and heating circuit controller
RVA
47,
the module control
unit
L
M
U
as well as the
heating circuit controllers.
An expert
allocates the addresses during start-up.
Two parameters (Device
address
140
and
segment address
141)
are available for this
purpose
.
The allocation is carried out according to the following
rules:
1.
The controllers of the heat generator
receive s
egment address
0.
The controllers of the heating circuits receive segment address
1.
The address format consists of two
points
for the s
egment
address and two points for the device address separated by a
period e.g.
RVA
47
with the address
00.01
2.
D
RVA
47
always receives the Device address
1.
RVA
47
can address up to
12
L
M
U's.
The
L
M
U
of the heat generator module
receives the Device
addresses
2
upwards irrespective of whether it is the master
or slave cascade boiler
.
3.
Never allocate an address twice
