Preface
The INIPR01 INFI-NET®to Plant Loop Remote Interface links a
remote satellite Plant Loop and a central INFI-NET loop. The
INFI-NET to Plant Loop remote interface (IPR) permits the
exchange of exception reports, configuration and control mes-
sages, and system status data between INFI-NET and Plant
Loop communication systems.
An INNIS01 Network Interface Slave Module, an INIPT02
INFI-NET to Plant Loop Transfer Module, and an IMMPI01
Multi-Function Processor Interface Module make up an IPR
remote interface. Two IPR interfaces, one connected to the
Plant Loop system and one connected to the INFI-NET system,
are required for a complete link.
This instruction explains the IPR interface features, specifica-
tions and operation. It also includes installation and trouble-
shooting procedures for each module.

Safety Summary
®
GENERAL
WARNINGS Equipment Environment
All components, whether in transportation, operation or storage,
must be in a noncorrosive environment.
Electrical Shock Hazard During Maintenance
Disconnect power or take precautions to insure that contact with
energized parts is avoided when servicing.
Special Handling
This module uses electrostatic sensitive devices.
SPECIFIC
WARNINGS Disconnect power before installing dipshunts on the module mount-
ing unit backplane. Failure to do so will result in contact with cabinet
areas that could cause severe or fatal shock. (p. 3-9, 3-18)
Wear eye protection whenever working with cleaning solvents.
When removing solvents from printed circuit boards using com-
pressed air, injury to the eyes could result from splashing solvent as
it is removed from the printed circuit board. (p. 6-1)
SPECIFIC
CAUTIONS Always operate the IPT module with the machine fault timer circuit
enabled. Unpredictable module outputs may result if the machine
fault timer circuit is disabled. These unpredictable module outputs
may adversely affect the entire communication system. (p. 3-14)
To avoid potential module damage, evaluate your system for com-
patibility prior to module installation. The INIPT02 module uses con-
nections to the module mounting unit backplane that served other
functions in early Network 90 systems. (p. 3-17)

AVERTISSEMENTS
D’ORDRE
SPÉCIFIQUE
Interrompez l'alimentation avant d'installer des dipshunts sur le fond
de panier du châssis de montage des modules. Sinon, tout contact
avec cette zone entraîne des risques d'électrocution sérieuse ou
fatale. (p. 3-9, 3-18)
Des lunettes de protection devraient être portées lors de travail
avec des solvants nettoyants. Lorsqu’on enlève les solvants des cir-
cuits imprimés à l’aide d’air comprimé, les éclaboussures de solvant
pourraient causer des blessures aux yeux. (p. 6-1)
ATTENTIONS
D’ORDRE
SPÉCIFIQUE
N'utilisez jamais un module IPT sans l'usage de sa minuterie de
détection de défaillance (MFT). Sinon, les sorties du module pour-
raient prendre des valeurs ou des états imprévisibles. Le comporte-
ment imprévisible des sorties pourrait perturber la totalité du
système de communication. (p. 3-14)
Afin d'éviter tout dommage au module, évaluer la compatibilité avec
votre système avant l'installation du module. Le module INIPT02
utilise des connexions sur le panneau arrière du chassis de mon-
tage des modules qui servaient à d'autres fonctions dans les
systèmes Network 90 de premières générations. (p. 3-17)

OVERVIEW
I-E96-613A 1 - 1
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 1-1). 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.

INTRODUCTION
MODULE DESCRIPTION
1 - 2 I-E96-613A
®
The IPR interfaces transfer system data, control and configura-
tion messages, and exception reports between the central and
remote satellite systems. Many of the operating characteristics
of the IPT module are determined by the specifications in the
INFI-NET to Plant Loop remote transfer module executive block
(function code 203). Configure these specifications to fit the
needs of the application.
MODULE DESCRIPTION
The IPR interface is made up of one INNIS01 Network Interface
Slave Module (NIS), one INIPT02 INFI-NET to Plant Loop Trans-
fer Module (IPT), and one IMMPI01 Multi-Function Processor
Interface Module. The central INFI-NET system and the remote
satellite Plant Loop system each require one IPR interface.
INNIS01 Network Interface Slave Module
The INNIS01 Network Interface Slave Module (NIS) works in
conjunction with the IPT module. This allows nodes within the
system to communicate with any other node.
The NIS module is a single printed circuit board that occupies
one slot in the module mounting unit. The circuit board con-
tains microprocessor based communication circuitry that
enables it to interface with either local IPT module (one in the
central INFI-NET system and one in the remote Plant Loop
system).
Two captive latches on the front-mounted faceplate secure the
module to the module mounting unit. There are 16 LEDs on
the faceplate that display error codes and event/error counts.
Each NIS module connects to its communication loop by a
cable connected to an NTCL01 Communication Termination
Unit (TCL) or an NICL01 Communication Termination Module
(ICL). Communication between nodes is through coaxial or
twinaxial cables that connect the termination units or modules
on each node.
Power and I/O expander bus connections follow the same con-
nector assignments common to most INFI 90 modules (P1 for
power, P2 for I/O expander bus). Connector P3 connects the
NIS module to the NTCL01 or NICL01 termination device.
INIPT02 INFI-NET to Plant Loop Transfer Module
The INIPT02 INFI-NET to Plant Loop Transfer Module (IPT) sup-
ports bidirectional communication through two RS-232-C
ports on the IMMPI01 Multi-Function Processor Interface Mod-
ule (MPI). Ports one and two pass system data. Connector P4 is

INTRODUCTION
FEATURES
I-E96-613A 1 - 3
a dedicated diagnostic port. The central INFI-NET IPT module
can use a variety of means to link to the remote satellite Plant
Loop IPT module such as a modem, microwave or transceiver.
The IPT module communicates directly with an NIS module
through the I/O expander bus.
The IPT module is a single printed circuit board that occupies
one slot in the module mounting unit, adjacent to its NIS and
MPI module. Two captive latches on the IPT module faceplate
secure the module in the module mounting unit. The faceplate
contains 16 CPU LEDs, a red/green status LED, and a stop/
reset pushbutton.
The IPT module is terminated through a 60-pin ribbon cable
connected to the IMMPI01 module. Power and I/O expander
bus connections follow the same connector assignments com-
mon to most INFI 90 modules (P1 for power, P2 for I/O
expander bus). Connector P3 is unused at this time.
IMMPI01 Multi-Function Processor Interface Module
The IMMPI01 Multi-Function Processor Interface Module (MPI)
provides the INIPT02 INFI-NET to Plant Loop Transfer Module
(IPT) with two RS-232-C communication ports. The MPI mod-
ule is an interface device that handles I/O to and from the IPT
module. Control and data signals from the IPT module travel
through a 60-pin ribbon cable to the MPI module.
The MPI module connects to an NTMP01 Multi-Function Pro-
cessor Termination Unit, NIMP01 or NIMP02 Multi-Function
Processor Termination Module. Input and output signals enter
and leave the MPI circuit board connector P3 through an
NKTU01, NKTU02, NKTU11 or NKTU12 cable to the termina-
tion device.
FEATURES
The INFI-NET to Plant Loop remote interface has the following
features:
•The IPR interface modules provide localized start-up/shut-
down on power failure without operator intervention.
•Each node can operate independently of other nodes.
•The IPR interface modules handle four message types:
Broadcast, time synchronization, multicast and NIS poll.
•All messages contain cyclic redundancy check codes (CRC)
and checksums to insure data integrity.
•The IPT module on the INFI-NET loop has full INFI-NET
communications diagnostics capability.

SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
INFI-NET and Plant Loop are unidirectional, serial data high-
ways that all INFI 90 nodes can utilize. The INIPR01 INFI-NET
to Plant Loop Remote Interface (IPR) enables communication
between a central INFI-NET node and a remote satellite Plant
Loop node. The INIPT02 INFI-NET to Plant Loop Transfer Mod-
ule (IPT), IMMPI01 Multi-Function Processor Interface Module
(MPI), and INNIS01 Network Interface Slave Module (NIS) make
up an IPR interface. Communication between a central
INFI-NET loop and a remote Plant Loop requires an interface
on each loop. This section of the product instruction provides
an overview of the interface module operating theory.
MODULE INTEGRITY
All INFI-NET communication modules have normal INFI 90
security functions that insure module integrity. Module hard-
ware checks for illegal addresses, and monitors the machine
fault timer and the I/O expander bus clock. If a module detects
an illegal address, it generates a bus error and displays an
error code on the faceplate LEDs. If the processor fails to reset
the machine fault timer, it expires. When this happens, the
communication module stops and the status LED turns red.
Module hardware also monitors the I/O expander bus clock. If
there is no clock signal, the module hardware generates an
interrupt.
INFI-NET to Plant Loop Messages
Central INFI-NET messages destined for the remote satellite
Plant Loop are received by the central INFI-NET NIS module.
The central INFI-NET NIS module sends messages over the I/O
expander bus to the central INFI-NET IPT module. The central
INFI-NET IPT module converts the messages to the appropriate
Plant Loop serial link format and transmits all commands and
replies through the central INFI-NET MPI module to the remote
satellite Plant Loop MPI module over the serial link. The remote
satellite MPI module passes the commands and replies to the
remote satellite Plant Loop IPT module which issues the appro-
priate Plant Loop formatted message to the remote satellite
Plant Loop NIS module for transmission around the Plant
Loop.

Plant Loop to INFI-NET Messages
Remote satellite Plant Loop messages destined for the central
INFI-NET loop are received by the remote satellite Plant Loop
NIS module. The remote satellite Plant Loop NIS module sends
the messages over the I/O expander bus to the remote satellite
Plant Loop IPT module. The remote satellite Plant Loop IPT
module converts all messages to the serial link format. These
commands and replies are transmitted through the remote sat-
ellite Plant Loop MPI module and across the serial link to the
central INFI-NET MPI module. The central INFI-NET MPI mod-
ule passes the commands and replies to the central INFI-NET
IPT module. The central INFI-NET IPT module issues the
appropriate INFI-NET messages to the central INFI-NET NIS
module for transmission around the INFI-NET loop.
INNIS01 NETWORK INTERFACE SLAVE MODULE
The NIS module serves as an I/O module for the IPT module.
This section provides an overview of the NIS module operating
theory.
Messages
The NIS module processes four different message types: Broad-
cast, time synchronization, multicast and NIS poll.
BROADCAST
A node generates a broadcast message when sending informa-
tion to all system nodes. Typically, these messages announce
changes in node status. Broadcast messages include NODE
ON-LINE, NODE OFF-LINE, NODE RESTART, and NODE BUSY.
TIME SYNCHRONIZATION
The time synchronization message is a high priority broadcast
type of message. The NIS module services this message type
immediately. Time synchronization provides a common system
time base to be used for sequencing exception reports access-
ing trend data and display on a system console.
MULTICAST
A message that contains data for multiple destinations is a mul-
ticast message. This message can have one to 64 destinations.
