ABB INFI-NET Interface Modules INTRODUCTION
INTRODUCTION
INFI-NET is a unidirectional, high speed serial data highway
shared by all INFI 90® OPEN nodes. The INFI-NET to INFI-NET
interface modules provide sophisticated interfaces for data
exchange between nodes on an INFI-NET communication net
work. These network interface units use state-of-the-art INFI
90 OPEN modules.
INTENDED USER
Anyone who installs, operates or performs maintenance on the
INFI-NET to INFI-NET interfaces should read this manual
before placing an interface into service. Installation requires an
engineer or technician with experience handling electronic cir
cuitry and who is familiar with communication networks.
This interface transfers system data, control and configuration
messages, and exception reports between the central and
remote INFI-NET loops. Many of the operating characteristics
of the INIIT12 module are determined by specifications in the
INIIT12 executive block (function code 202). These specifica
tions are configurable to fit the needs of the application.
