A basic FX PLC system can consist of a stand alone base unit, with the functionality and I/O
range increased by adding extension I/O and special function modules. An overview of available
options is given in sections 2.8 and 2.9.
Base Units
Base units are available with different I/O configurations from 10 to 128 points but can be
expanded to 384 points depending upon the FX range selected.
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 extension adapter boards
can be installed directly into the FX
vide the FX PLC with additional RS232 or RS485 interfaces.
Extension I/O Modules
With the exception of the FX
pact extension units modules can be added to all base units of the FX family. For modular exten-
sion blocks powered by the base unit, the power consumption has to be calculated as the 5 V DC
bus can only support a limited number of expansion I/O.
Special Function Modules / Special Adapters
A wide variety of special function modules are available for all FX PLCs, again the exception is
