DFANA-M
DFANA-M: network analyzer module for
Domino
bus
DFANA-M and DFANA-S modules allow the measurements
of electrical variables of a three-phase network and it is
available, under request only, in special version for sin-
gle-phase network. DFANA-M module interfaces directly to
the
Domino
bus, thus making the measurements immedi-
ately available and easy to use. The measurements are
also showed on the front panel of DFANA-S by through a
back-lighted LCD display.
Among the several available measurements, shown on the
display of DFANA-S (with the symbol showed in the follow-
ing table), DFANA-M can report on the bus up to 20 vari-
ables to be chosen among the following:

DFNA-M module features a 2-way fixed terminal block for
the connection to
Domino
bus and a 3-way fixed terminal
blocks for the connection to DFANA-S module.
For information about terminal blocks, connections and the
several possible settings of the measurements section of
DFANA-S module, refer ti the related User's Manual
(DFANA-S_xxMIT).
Near to the bus terminal block, DFANA-M module features
a small pushbutton and a green LED that shows the oper-
ating status; this LED normally flashes every 2 seconds
about to signal that the module is properly connected to the
bus. DFANA-M module is housed in a standard 2M modu-
lar box for rail mounting
Note:
the setting up of DFANA-M module requires BDTools or
DCP IDE software.
Address programming
DFANA-M module takes, in dynamic mode, up to a maxi-
mum of 20 consecutive input addresses and, if enabled, 1
output address equal to the base address; the address can
be assigned by DFPRO programmer or by BDTools or
DCP IDE. A white label on the front panel allows the writing
of the assigned base address for an immediate visual iden-
tification. The effective amount of used addresses depends
on the number of measurements to be transferred on the
bus.

tween DFANA-M. DFANA-S and and
