YOKOGAWA Serial Communication Modules ALR121

GENERAL

This document describes about Models ALR111 and ALR121 Serial Communication Modules (for FIO) that a field control station (FCS) uses to perform serial communication with subsystems such as FA-M3. These serial communication modules can be mounted on field control units (AFV30, AFV40, AFV10, and AFF50), ESB bus node unit (ANB10), optical ESB bus node unit (ANB11), and ER bus node unit (ANR10).

*1: The applicable transmission speed depends on the communication function, subsystems, and connection method.

An FCS collects data from subsystems or sets data with control calculations to subsystems using the builder functions

by way of serial communication modules. A communication module selects only one communication function, thus

two ports must have identical communication functions. It is not possible to select different communication function

for every port. The communication functions and those transmission speeds for each communication module are as

shown in the table below.
