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.

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.
