SECTION 1 - INTRODUCTION
OVERVIEW
INFI-NET is a unidirectional, high speed serial data communi-
cation highway shared by all INFI 90
®
nodes. Plant Loop is a
unidirectional, medium speed serial data communication high-
way. The INIPR01 INFI-NET to Plant Loop Remote Interface
(IPR) provides for data exchange between a central INFI-NET
system and a remote Plant Loop system.
INTENDED USER
Anyone who installs, operates or performs maintenance on the
IPR interface should read this instruction before placing the
interface into service. Installation requires an engineer or tech-
nician with experience handling electronic circuitry and who is
familiar with communication networks.
INTERFACE DESCRIPTION
Two interconnected IPR interfaces provide a communication
path between a central INFI-NET system and a remote satellite
Plant Loop system (see Figure
). Bidirectional communica-
tion between the central system and the remote satellite sys-
tem is through standard RS-232-C ports. A single serial
channel is required for communications while two serial ports
can be used for increased throughput or redundancy. The
actual link between the central IPR interface and the remote
satellite IPR interface must be supplied by the customer.
