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.
