A1.1 System Configuration
 Basic Configuration
The basic configuration of FA-M3 is a unit.
A unit is a system with the minimum configuration consisting of the following modules.
Install these modules on the base module to compose the unit.
Table A1.1 Modules (Components) of a Unit
Module Description
Base module Six types are available, allowing different number of
modules to be mounted.
Power supply module A unit must have at least one power supply module.
CPU module Different types are available with different
functionalities. A unit must have at least one CPU
module.
I/O module Various types are available with different I/O and
number of I/O points.
Special module Various types are available, including analog I/O
and communication modules.
 Main Unit
A unit in which a CPU module is installed is referred to as a main unit. Thus a main unit
is comprised of only one unit.
The unit number of a main unit is 0.
 Subunit
Subunits are used to increase the number of I/O ports. A subunit contains no CPU
module. A maximum of seven subunits can be added to the system to handle up to 8192
(depending on the CPU module type) I/O points. The unit number of a subunit is either
1, 2, 3, 4, 5, 6, or 7.
