ALR121-S01 YOKOGAWA Multipoint Serial Communication Modules Field Control Station ESB Bus Node Unit
ALR121-S01 YOKOGAWA Multipoint Serial Communication Modules Field Control Station ESB Bus Node Unit
Description:
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.
This document describes about Models ALR111 and ALR121 Serial Communication Modules (for N-IO/FIO) that a field control station (FCS) uses to perform serial communication with subsystems such as FA-M3.
