1. Notes to User

1.1 Outline of product

The MELSEC-I/O LINK REMOTE I/O SYSTEM MASTER BLOCK FX2N-16LNK-M (hereinafter referred to as

"master block") is connected to an FX0N/FX1N/FX2N/FX2NC Series programmable controller (PC), and realizes

a remote I/O system which saves wiring and enables easy programming for communication with remote I/O

units.

Applicable PC

The master block can be connected as a special block of an FX0N/FX1N/FX2N/FX2NC Series PC.

When it is connected to an FX2NC Series PC, a connector conversion interface FX2NC-CNV-IF is required.

Features

1 ) Many control points

One master block can control up to 128 points (64 input points and 64 output points) (when mixed I/O

type remote I/O units having 8 or 16 control points are used).

To one master block, up to 16 remote I/O units can be connected.

2 ) Wiring saving

A master block and a remote I/O unit can be easily connected with a twisted-pair or cabtyre cable.

3 ) Total extension distance: 200 m

The distance can be extended up to 200 m in the entire system.

Terminal resistors are not required, and connection using T branches can be realized.

4 ) Free from system down caused by failure in one station

Even if failure has occurred in a remote station in the system, the system does not come down.

Diversified error indication LEDs facilitate quick troubleshooting.

5 ) Easy programming

Element Nos. for inputs (X) and outputs (Y) are assigned to remote I/O units in the same way as general

I/Os.

Communication programs are not required.
