GENERAL

This document describes about Model ALF111 FOUNDATION  fieldbus Communication Module (for FIO) which is to es- tablish communication between field control stations (FCS) and fieldbus devices compliant to the FOUNDATION  fieldbus

(H1) such as transmitters and valve positioners.

This FOUNDATION  fieldbus communication module can be mounted on the 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).

Fieldbus power supply units (*1) and terminators are required depending on the network configuration.

 
HARDWARE SPECIFICATIONS

The FOUNDATION  fieldbus communication module (ALF111) performs as the Link Active Scheduler (LAS) to exchange

data with devices compliant with FOUNDATION  fieldbus (H1) protocol.  The hardware specifications for this module are as

shown in the table below.
