What Components Are Required for an FX PLC System?
A basic FX PLC system c an consist of a stand
alone base unit, with the functionality and I/O
range increased by adding extension I/O and
special func tion modules. The following sec
-
tion provides an overview of options available.
Base units

-
ered with a mix of input and output styles. The
PLCscanbeprogrammedwiththeuserfriendly
GX or GX IEC Developer programming software,
allowing programs to be transferred between
different FX PLCs. All PLC base units include an
integrated real time clock.
Base units are available with different I/O con-
figurations from 10 to 128 points but can be
expanded to 384 points depending upon the
FX range selec ted.
Extension boards
Extension adapter boards can be installed
directly into the base unit and therefore do not
require any additional installation space. For a
small number of I/O (2 to 4) an ex tension
adapter boards can be installed directly into
the (lef t-hand side) FX1S or FX1N controller.
Interface adapter boards can also provide the
FX PLC with additional RS232 or RS485 inter
-
faces.To connec t special func tion modules
(e.g. Ethernet module) a communication
adapter has to be installed.
Extension I/O modules
Unpowered and powered ex tension I/O mod-
ules can be added to the FX1N, FX2N, FX3U and
FX3UC PLCs. For expansion modules powered
by the base unit, the power consumption has to
be calculated as the 5 V DC bus can only sup
-
port a limited number of expansion I/O (for
further details please refer to next page –
calculation of the power consumption).
Special function modules
A wide variety of special function modules are
available for the FX1N, FX2N, FX3U and FX3UC
PLCs. They cover network ing functionality, ana
-
log control, pulse train outputs and tempera
-
ture inputs.
Peripherals
Each FX PLC has options for memory cassettes,
hand held programming units as well as con-
nection to HMI and GOT interfaces.
