R-DPA96 A/AN - R-Module 3 (
RS485 - JBUS/MODBUS
®
)
GENERAL INFORMATION
FUNCTIONS
The optional IP Communication module must be
connected to the
R-DPA96 A/AN
(réf. : 4825 0A40,
4825 0A41, 4825 1A40, 4525 1A41). It provides an
RS485 serial link (2 or 3 wires) with JBUS/MODBUS
®
protocol for the use of
R-DPA96 A/AN
from a PC or
PLC.
GENERAL POINTS
For a standard configuration, an RS 485 link is used to
connect up to 31
R-DPA96
with a PC or a PLC over a
distance of 1500 metres, using JBUS/MODBUS

Recommendations:
You should use a shielded twisted pair (LIYCY type).
In a disturbed environment or large network (in terms
of length) we recommend the use of 2 shielded pairs
(type LIYCY-CY). In this case, one pair is used for the
+ and the –, and another pair, where the 2 wires are
short-circuited, for the 0 V.
A repeater (1 channel) or an arrestor (4 channels)
should be used if you intend to exceed the distance
(1500 m) and/or maximum number (31) of
R-DPA96
.
Please contact us for more information.
NB :
A 120 ohm resistance (found on the additional module)
must be fixed at both ends of the link.
Other solutions are available (modem, optical fibre, etc.).
Please contact us.
