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) Data transfer function using the non-procedure method.

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 Communication User’s

Manual.

2) Data transfer function using a 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 Communication

User’s Manual.

3) Parallel link function.

The 485BD transfers automatically 50 auxiliary relays and 10 data registers when two FX1S Series

PLC’s (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 Communication User’s Manual.

4) Easy PC link function.

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

FX1N/FX0N/FX2N/FX2NC Series PLC units are connected. For the setting procedure and program

examples, refer to the FX Series Communication User’s Manual. For the FX2N Series PLC, the version

should be 2.00 or greater (manufacturer’s serial No. 780000 or later).

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: This screw cannot be removed.

• 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.
