Associated Manuals

1. Outline of Product

The RS-485 communication board FX1N-485-BD (hereafter referred to as "485BD") is connected to the

FX1S/FX1N Series PLC basic unit, and available for the applications described below.

Only one function expansion board can be connected to one PLC basic unit. Accordingly, the 485BD cannot

be used together with the FX1N-422-BD or the FX1N-232-BD.

1.1 Features

1) No protocol communication.

The 485BD transfers the data using the RS instruction between a bar code reader, personal computer

or printer.

As the 485BD is not equipped with buffer memory, it sends and receives the data using data registers

specified by the RS instruction.

For the RS instruction and the communication setting, refer to the FX Series User's Manual - Data

Communication Edition.

2) Computer link by dedicated protocol.

The 485BD transfers the data when a personal computer directly specifies devices of the PLC.

For the dedicated protocol and the communication setting, refer to the FX Series User's Manual - Data

Communication Edition.

3) Parallel link.

The 485BD transfers automatically auxiliary relays and data registers when two FX1S Series PLC’s or

two FX1N Series PLC’s are connected on a one-to-one basis.

For the setting procedure and program examples, refer to the FX Series User's Manual - Data Commu-

nication Edition.

4) N:N network.

The 485BD transfers automatically up to 64 auxiliary relays and 8 data registers when up to eight FX1S/

FX1N Series PLC units are connected. For the setting procedure and program examples, refer to the

FX Series User's Manual - Data Communication Edition.

2. Installation

2.1 Installation procedure

Make sure to turn off the power before installing the 485BD.

A) Communication board 485BD (function expansion board)

B) Connector for optional equipment

C) M3 screw to fix board (2 pieces) (offered as accessories of board)

D) Top cover for board (offered as an accessory of board)

E) M3 screw to fix top cover (offered as an accessory of board)

Note: Do not remove this screw of FX1S.

• Plug the communication board A) in to the connector B).

• Fix the board to the basic unit with two M3 screws C). (Tightening

torque: 0.3 to 0.6 Nxm)

• Remove the top cover of the basic unit, and attach the top cover for

board D) instead.

During attachment, remove D)’ with a nipper, etc. so that the connector of the board is exposed.

• Fix the top cover with the M3 screw E). (Tightening torque: 0.3 to 0.6 Nxm)

• When the FX1N-5DM is used also, refer to the Hardware manual offered with the FX1S/FX1N Series

PLC main unit.

• Only one function expansion board is available for one FX1S/FX1N Series PLC basic unit. Never stack

up two or more function expansion boards. (Even if they are stacked up, they do not function at all.)

• The 485BD can be used with the FX1N-EEPROM-8L only for program transfer.

(The FX1N-EEPROM-8L cannnot be connected continuously.)
