Instruction Manual C200
2.4 Measuring input addresses
The measuring inputs are referred to
as
P1
to
P8
for subsequent programming.
The bottom measuring input is always
P1
. It is possible to connect more than 8
measuring inputs, the
C200
column gauge,
however, can only address and read in the first
8 inputs.
Note :
When connecting further column gauges via
IMB-cas
adapter cables, the measuring inputs
( P1
to
P8
)
of the first column gauge are also
available at the subsequent column gauges
and are referred to as the
same addresses.
Therefore, there is no complex behaviour to pay
attention to when programming.
When connecting several column gauges, please take
into account the following facts:
A further measuring module in a series of column gauges
will interrupt the connection to the previous measuring
modules, and make available its inputs for the subse-
quent column gauges, including the one it is fitted into.
See also example 2 on page 14 of this manual.
Note for wireless application :
The
IMB-rf1
modules allow the reception of measure-
ment values from 1…8
IBRit-rf1
radio modules. There-
fore each
IMB-rf1
module contains eight channel num-
bers.
Each channel can be assigned to one of the 1...120
addresses of an
IBRit-rf1
radio module.
When you use an
IMB-rf1
module together with other
IMB-modules in one
C200
, then you must install the
IMB-rf1
module as the last module of the
C200
( upper
position ). Because the
C200
supports only eight chan-
nels and the
IMB-rf1
has already eight channels, all other
IMB-modules behind the
IMB-rf1
module are ignored by
the
C200
.
The programming of
IBRit-rf1
radio modules and the
address assignment of the 1…120
IBRit-rf1
module
addresses to the 1…8
IMB-rf1
channels can be done
by using the PC software
C200_PC
(
provided by IBR
free of charge ). The settings are made in the menu
“Programming of IMBus modules”.
