MELSEC FX0N/FX2N
SYSTEM DESCRIPTION
Extension and Special Function Modules
In general
Additional special function modules are
available that make it possible to extend
the capacity of the basic and extension
units of your PLC system.
There are three basic categories of special
function modules:
Modules that occupy digital I/Os (con-
nected on the right hand side of the
controller unit). These are the digital
compact and modular extension units
as well as the special function modules.
Modules of the FX0N series that do not
occupy any digital I/Os (connected on
the left hand side of the controller unit).
These are the FX0N-232ADP and the
FX0N-485ADP.
Internal adapter boards for the FX2N
series. These expansion units are in-
stalled directly in the controller and do
not occupy any digital I/Os.
FX0N series configuration notes
The configuration specifications for the
FX0N series permit connection of the follow-
ing combinations of expansion units to the
base units:
a maximum of 2 special function
modules
or
digital expansion modules with up to
32 inputs and outputs (4 x 8 I/Os or
2x 16 I/Os)or
one special function module and one
digital expansion module with up to
16 inputs and outputs (2 x 8 I/Os or
1x 16 I/Os)
The same configuration specifications apply
for the connection of compact expansion
modules.
Provided you observe these rules the sys-
tem’s power supply will also be adequate to
provide the 24 V DC input required by the
FX0N-232ADP communications module.
Similarly, the power supply for MMIs such
as the FX-DU control panels and MAC
operator terminals is provided via the
system’s 5 V bus.
FX2N series configuration notes
The configuration specifications for
the FX2N series permit connection of
the following combinations of units:
A maximum of 8 special function
modules or
Digital expansion modules with up
to 256 I/Os
Please note that it is important to cal-
culate the connected load to ensure
that the internal 5 V bus has adequate
capacity for the installed modules.
When using special function modules
you must also check the 24 V power
supply load – the necessary 24 V
power can be drawn from the internal
service power supply, but it may be
necessary to complement this with an
external power supply in some con-
figurations.
You can calculate the precise power
load with the values provided in the
table on the next page.
