A1. Overview
The Model F3LR01-0N Fiber-optic FA-
bus Module (hereinafter referred to as ‘the
module’ or ‘this module’) is an interface module for configuring a distributed control
system on a fiber-optic FA bus.
A user can configure an efficient remote I/O system by installing Fiber-optic FA-bus
modules in the FA-M3 main unit and subunits and connecting them via a fiber-optic FA
bus (fiber-optic cable). Modules in the subunits can then be handled like modules in the
main unit.
A1.1 Features
A remote I/O system
*1
configured with Fiber-optic FA-bus modules has the following
features.
- Users need not be concerned with I/O refresh time in ladder programming.
- Subunits can include contact input/output modules, as well as RS-232-C
communications modules and other special modules (except for Ethernet Interface
modules, NX Interface modules, FL-net Interface modules, FA Link H modules, FA
Link H2 modules, Fiber-optic FA Link H modules, Hard Disk modules, and PC Card
modules).
- Subunits connected with Fiber-optic FA-bus modules can be accessed like modules
installed in a main unit.
- Optical transmission delivers high noise immunity.
- The maximum permissible total distance is 200 meters.
*1: I/O refers to contact input and output modules.
Remote I/O is located far away from the CPU module, but can be handled in the same way as contact input/output
modules close to a CPU module.
