Product Description Ordering Key

G 3496 0004 is designed as a

cost-effective solution for

interfacing Dupline®I/O’s to a

Omron PLC. It performs three

functions: Dupline®channel

generator, power supply syn-

chronization (enables 3-wire

system with supply) and

RS232/RS422/RS485 inter-

face.

Mode of Operation

The Dupline

Master Module

(DMM) controls a 3-wire bus

with signal, DC-power and

common GND. The DMM is

connected to a standard DC-

supply, which it synchronizes

with the Dupline

carrier signal

before it is output to supply.

The synchronization is neces-

sary in order to enable the

Dupline

and DC-supply to

share the GND-wire.

The Dupline

Master Module is

a Dupline

Channel Generator

with the function of a master.

This means that the 128

Dupline

I/O’s will be read/writ-

ten by the DMM and then sent

to the PLC.

The DMM can run in two dif-

ferent modes – Normal mode

and split I/O mode. In Normal

mode, Dupline

operates as a

peer-to-peer system, where

the channel generator auto-

matically establishes a con-

nection between Dupline

inputs and Dupline

outputs

which are coded to the same

Dupline

address. If e.g. an

input coded for B5 is activat-

ed, the output(s) coded for B5

will also be activated.

Consequently, a Dupline

-out-

put can either be activated

through the output-data

received on DMM or by an

active Dupline

input coded

for the same Dupline

address. In “Split I/O” mode,

the channel generator treats

the Dupline

inputs and

Dupline

outputs indepen-

dently. If e.g. an input coded

for B5 is activated, the DMM

will make the information avail-

able for the PLC (like in normal

mode), but it will not automati-

cally activate the Dupline

out-

put(s) coded to B5. The

Dupline

outputs are con-

trolled exclusively through the

output data received from the

PLC. In this mode, up to 128

Dupline

inputs and 128

Dupline

outputs are available,

since an input and an output

coded to the same Dupline

address can operate indepen-

dently.
