Example of Increasing the Number of I/O Points Using Fiber-optic
FA-bus Type 2 Modules
You can install fiber-optic FA-bus type 2 modules in both main and subunits and connect
them with fiber-optic cables. This enables distributed arrangement of remote I/O points,
increase in the number of I/O points, and control of I/O modules via high-speed, noise-
immune communication.

Figure A1.4 Increasing the Number of I/O Points Using Fiber-optic FA-bus Type 2 Modules
The maximum number of subunits that can be connected is 7.
Subunit numbers are determined depending on the setting of the rotary switch on the
fiber-optic FA-bus type 2 module mounted to a subunit.
