Preface
The INICI01 and INICI03 INFI-NET®to Computer Interfaces
provide a host computer or console with access to an INFI-NET
communication loop. State-of-the-art INFI 90®modules are
used in these interfaces.
The INNIS01 Network Interface Slave Module (NIS) is a part of
all INFI-NET to computer interfaces. It provides the intelligent
link between a node and an INFI-NET loop. One NIS module
and one INICT01 INFI-NET to Computer Transfer Module make
up an INICI01 INFI-NET to Computer Interface. One NIS mod-
ule, one INICT03 INFI-NET to Computer Transfer Module, and
one IMMPI01 Multi-Function Processor Interface Module make
up an INICI03 INFI-NET to Computer Interface.

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 (ESD).
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. 3-8, 3-12, 3-20)
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 blown off the printed circuit board. (p. 6-1)
SPECIFIC
CAUTIONS Never operate the ICT module with the machine fault timer circuit
disabled (jumper pins connected). Unpredictable module outputs
may result. These unpredictable module outputs may adversely
affect the entire communication system. (p. 3-16)
To avoid potential module damage, evaluate your system for com-
patibility prior to module installation. This module uses connections
to the module mounting unit backplane that served other functions
in early Network 90 systems. (p. 3-19)

AVERTISSEMENT
D'ORDRE
SPECIFIQUE
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. 3-8, 3-12, 3-20)
Portez toujours des lunettes de protection lorsque vous utilisez des
solvants de nettoyage. L'air comprimé servant à enlever le solvant
des cartes de circuits imprimés provoque des éclaboussures qui ris-
quent d'atteindre les yeux. (p. 6-1)
ATTENTION
D'ORDRE
SPECIFIQUE
Ne jamais faire fonctionner le module ICT alors que le circuit MFT
(Machine Fault Timer) est hors-circuit. Il pourrait en résulter des sor-
ties imprévisibles. Ces sorties imprévisibles pourraient affecter trés
défavorablement le systéme entier de communication. (p. 3-16)
Pour éviter d'endommager des modules, évaluez la compatibilité de
votre système avante de les y brancher. L'usage que fait ce module
de certaines connexions au fond de panier du châssis de montage
diffère de l'assignation prévue par le système Network 90 original.

OVERVIEW
I-E96-610A 1 - 1
SECTION 1 - INTRODUCTION
OVERVIEW
INFI-NET is a unidirectional, high speed serial data highway
shared by all INFI 90 nodes. INFI-NET utilizes sophisticated
computer interfaces for data exchange. These computer inter-
faces use state-of-the-art INFI 90 modules.
INTENDED USER
Personnel installing, operating, or maintaining the INFI-NET to
computer interfaces should read this manual before performing
any installation, operation, or maintenance procedures. Instal-
lation requires an engineer or technician experienced handling
electronic circuitry and familiar with communication networks.
COMPUTER INTERFACE DESCRIPTION
The computer interfaces are the INICI01 and INICI03 INFI-NET
to Computer Interfaces. The INNIS01 Network Interface Slave
Module (NIS) is a part of all INFI-NET to computer interfaces. It
is the intelligent link between a node and the INFI-NET loop.
The NIS module and other modules make up a specific com-
puter interface. Refer to Figure 1-1.
INICI01 INFI-NET to Computer Interface
The INICI01 INFI-NET to Computer Interface (ICI) is made up of
the NIS module and the INICT01 INFI-NET to Computer Trans-
fer Module (ICT). This computer interface gives a host com-
puter access to point data. Point data is available through an
RS-232-C serial link at standard rates up to 19.2 kilobaud.
The INFI-NET to computer interface is command driven
through software on the host computer. The ICI computer
interface receives a command from the host computer, exe-
cutes it and then replies to the host computer.
INICI03 INFI-NET to Computer Interface
The INICI03 INFI-NET to Computer Interface (ICI) is made up of
the NIS module, the INICT03 INFI-NET to Computer Transfer
Module (ICT), and the IMMPI01 Multi-Function Processor
Interface Module (MPI). This computer interface gives a host
computer access to point data. Point data is available through
an RS-232-C serial link at rates up to 19.2 kilobaud or through
a SCSI parallel port. The INFI-NET to computer interface is
command driven through software on the host computer. The
ICI computer interface receives a command from the host com-
puter, executes it and then replies to the host computer.

MODULE DESCRIPTION
A description of each module used in the INICI01 and INICI03
INFI-NET to Computer Interfaces follows.
INNIS01 Network Interface Slave Module
The NIS module is an I/O module that works in conjunction
with the other INFI-NET communication modules. This allows a
node to communicate with any other node on the INFI-NET loop.
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 other INFI-NET communication
modules. All INFI-NET to computer interfaces require a specific
communication module or modules and the NIS module.
Two latching screws on the faceplate secure the NIS module to
the module mounting unit. There are sixteen LEDs on the face-
plate that display error codes and event/error counts.
The NIS module has three card edge connectors for external sig-
nals and power (connector P1, P2 and P3). Connector P1 con-
nects to common (ground) and +5 VDC power. Connector P2
connects the NIS module to the I/O expander bus to communi-
cate with a control module within its node. Serial communication
to other nodes is through connector P3 using a cable connected
to a termination unit or termination module. Communication
between nodes is through coaxial or twinaxial cables that con-
nect the termination units or modules on each node.

INICT01 INFI-NET to Computer Transfer Module
The INICT01 INFI-NET to Computer Transfer Module (ICT) pro-
vides the electronics needed to direct the operation of the
INICI01 INFI-NET to Computer Interface. It handles all com-
munication with the host computer through RS-232-C serial
communication ports (one or both) and communicates directly
with the NIS module over the I/O expander bus.
The ICT module consists of two printed circuit boards. One cir-
cuit board is a memory board while the other is a central pro-
cessing unit. These boards contain the serial communication
circuitry necessary for the ICT module to communicate with a
computer. The ICT module occupies two mounting unit slots
adjacent to its associated NIS module.
Two latching screws on the ICT module faceplate secure the
module in the module mounting unit. The faceplate contains
eight CPU LEDs, two memory LEDs, a stop switch, and a reset
switch.
The communication path to the computer is through a cable
connection between connector P3 of the ICT module and a
NTMF01 Multi-Function Controller Termination Unit or
NIMF01 Multi-Function Controller Termination Module. Power
and I/O expander bus connections follow the same connector
assignments common to most INFI 90 modules (connector P1
for power, connector P2 for I/O expander bus).
INICT03 INFI-NET to Computer Transfer Module
The INICT03 INFI-NET to Computer Transfer Module (ICT) pro-
vides the electronics needed to direct the operation of the
INICI03 INFI-NET to Computer Interface. It handles all com-
munication with the host computer through the IMMPI01
Multi-Function Processor Interface Module (MPI), RS-232-C
(one or both) or SCSI communication ports. The ICT module
also communicates directly with the NIS module over the I/O
expander bus.
The ICT module consists of one printed circuit board. This
board contains the communication circuitry necessary for the
ICT module to communicate, through an MPI module, with a
host computer. The ICT module occupies one module mount-
ing unit slot adjacent to its associated NIS module and MPI
module.
Two latching screws on the ICT faceplate secure the module in
the module mounting unit. The faceplate contains 17 CPU
LEDs and a stop/reset switch.

The host computer can be connected to the ICT module in one
of two ways. One way is to connect a SCSI communication
cable from the SCSI port on the MPI faceplate to the SCSI port
on the host computer. The other way is to connect a NKTU01,
NKTU02, NKTU11, or NKTU12 cable from the MPI module to
the NTMP01 termination unit or NIMP01 termination module
and then an RS-232-C communication cable from the termina-
tion device to the RS-232-C port on the host computer. Power
and I/O expander bus connections follow the same connector
assignments common to most INFI 90 modules (connector P1
for power, connector P2 for I/O expander bus).
IMMPI01 Multi-Function Processor Interface Module
The IMMPI01 Multi-Function Processor Interface Module (MPI)
provides the INICT03 INFI-NET to Computer Transfer Module
(ICT) with communication ports. It contains I/O ports (i.e.,
RS-232-C, SCSI) that the ICT module can use. The MPI module
is an interface device that handles I/O to and from the ICT
module. Control and data signals from the ICT 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 or NIMP01 Multi-Function Processor
Termination Module. Input and output signals enter or leave
the MPI circuit board through a NKTU01, NKTU02, NKTU11, or
NKTU12 cable to the termination device. The SCSI connection
comes out of the faceplate for connection to a host computer.
FEATURES
The INFI-NET to computer interfaces have the following fea-
tures:
•INFI-NET, which provides a plantwide communication net-
work, is used.
•INFI-NET time synchronizes the control process plantwide.
•Each INFI-NET node can operate independently of other
INFI-NET nodes.
•Computer interface modules provide localized start-up and

INTRODUCTION
I-E96-610A 2 - 1
SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
INFI-NET is a unidirectional, high-speed serial data highway
that can be used by all INFI 90 modules. The INNIS01 Network
Interface Slave Module (NIS) and the INICT01 INFI-NET to
Computer Transfer Module make up the INICI01 INFI-NET to
Computer Interface. The NIS module, INICT03 INFI-NET to
Computer Transfer Module, and the IMMPI01 Multi-Function
Processor Interface Module make up the INICI03 INFI-NET to
Computer Interface.
MODULE INTEGRITY
All INFI-NET communication modules have normal INFI 90
security functions that insure module integrity. The module
hardware checks for illegal addresses and monitors the
machine fault timer (MFT) 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 micropro-
cessor fails to reset the MFT timer, it expires. When this hap-
pens, 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 gen-
erates an interrupt.
INNIS01 NETWORK INTERFACE SLAVE MODULE
The NIS module serves as an I/O module to both the INICT01
and INICT03 modules. While each computer interface uses dif-
ferent INFI-NET communication modules, the NIS module
operates with each communication module in the same man-
ner. This section provides an overview of INFI-NET communi-
cation module operating theory.
Exception Reports
Each INFI 90 module establishes exception reporting parameters
for process inputs (points). Some examples of exception report
parameters are high and low alarm limits, minimum and maxi-
mum report time intervals, and percent of change in span limits.
When a point changes more than a given parameter, or an alarm
state changes, the module generates an exception report.
The computer transfer module polls modules (via the Control-
way or module bus) for exception reports, and packs the excep-
tion reports having a common node destination. Packing
places all exception reports for a destination (or multiple desti-
nations) into one message (of variable length). The NIS module
