The FX2N-485BD interface adapter board
provides the FX2N unit with an additional
RS-485 interface. The adapter, which is sim-
ply inserted into the base unit’s expansion
slot, enables the configuration of RS-485
1:n multidrop, parallel link or peer-to-peer
networks with FX0N/FX2N systems.
You can also transfer data directly to other
RS-485 peripherals using the RS dedicated
instruction.
In peer-to-peer network configurations
the adapter enables active communica-
tion between the individual FX0N/FX2N
controllers via the RS-485 interfaces.
In 1:n multidrop networks the adapter
can be use to provide communication
with a host master station of the A series.

The FX0N-485ADP communications mod-
ule enables the configuration of 1:n mul-
tidrop, parallel link and peer-to-peer data
networks using the RS-485 interface.
Configuration of peer-to-peer data net-
works requires version 2.00 of the FX0N-
485ADP (see p. 21 for details).
In FX0N systems the module is con-
nected directly to the communications
bus on the left-hand side of the FX0N
base unit. The FX2N-CNV-BD communi-
cations adapter is required for connec-
tion to FX2N base unit.
