SETTING PARAMETERS
To minimise the dimensions of the product,
the pulse concentrator module parameters
can only be set with the help of:
- the CX³ EMS configuration software
or
- the mini-configurator Cat.No 4 149 36.
■ Possible settings for the pulse
concentrator module:
For each of the 3 pulse inputs, the pulse
weight can be modified as well as the
measurement unit of.
Setting parameters on the
mini-configurator:
Setting parameters on the CX³ EMS
configuration software:
Setting parameters is identical
and easily done using either
method.
DATA TRANSFER
The measurement module sends the
information back directly to the CX³ EMS
bus, allowing the data to be fed back to
an operating system.
As seen on page 23 (section
«Viewing data»), the information is
available on the mini configurator
Cat.No 4 149 36, the touch screen Cat.No
0 261 56, the Energy Management Software
Cat.No 4 149 38/39 and the Energy Web
Servers Cat.No 4 149 47/48/49.
The Modbus register table is available for
use by a system integrator. In this case,
an CX³ EMS / RS485 Modbus interface is
required.
MODBUS ADDRESSING
Addressing can be done:
■ Locally on the product
- addressing from 1 to 9 using a selector.
■ Via software
– addressing from 1 to 247,
– the selector then stays on 0.
The specifications for connection
to the CX³ EMS bus are common
to all CX³ EMS devices and are
described in the product technical data
sheets.
Local setting using the selector
takes priority over software
Setting parameters. In the event
of malfunction, check that the selector is
definitely on zero.
