ABB has developed a wide portfolio of control

cabinets to be able to meet today’s diverse and

evolving customer requirements within power

distribution. The ready-made solutions offer a

cost-effective and convenient way to increase

automation in the distribution network to

improve the availability and reliability of power

supply. The modular cabinet design also supports

fully customized solutions. Secure connectivity

over the wireless network makes accessing the

remote assets both easy and cost-effective.

Improved availability and reliability of power supply

Uninterrupted power supply is not only a practical

necessity in everyday life and business, but is also

crucial to securing the availability of vital public

services, such as emergency services, infra

structure and other important locations, such as

commercial centers.

The INIIT12 INFI-NET to INFI-NET Transfer Module supports

bidirectional communication through two RS-232-C ports. Port

one passes system data only. Port two passes system data or

can be used as a diagnostic port. The central INIIT12 module

can use a variety of means to link to the satellite INIIT12 mod

ule such as modems, microwave and transceivers. The INIIT12

module communicates directly with an NIS module through

the I/O expander bus.

The INIIT12 module is a single printed circuit board that occu

pies one slot in the module mounting unit, adjacent to its NIS

module. The circuit board contains the serial communication

circuitry necessary for it to communicate with another INIIT12 module.

Two captive latches on the INIIT12 faceplate secure the module

in the MMU card cage. The faceplate contains eight CPU LEDs,

a red/green status LED, and a stop/reset switch.

Interface termination is through a cable connection between

P3 of the INIIT12 module and an NTMP01 Multi-Function Pro

cessor Termination Unit or NIMP01 Multi-Function Processor

Termination Module. INIIT12 module power and I/O expander

bus connections follow the same connector assignments com

mon to most INFI 90 OPEN modules (P1 for power, P2 for I/O expander bus).

Communication between nodes is through coax or twinax

cables that connect the termination units or modules on each

node. Power and I/O expander bus connections follow the

same connector assignments common to most INFI 90 OPEN

modules (P1 for power, P2 for I/O expander bus).

INIIT12 INFI-NET to INFI-NET Transfer Module

The NIS module works in conjunction with the INFI-NET to

INFI-NET transfer modules. This allows any node to communi

cate with any other node within the INFI-NET system.

The NIS module is a single printed circuit board that occupies

one slot in the module mounting unit (MMU). The circuit board

contains microprocessor based communication circuitry that

enables it to interface with the INFI-NET to INFI-NET transfer

modules via the I/O expander bus. Both the INFI-NET to

INFI-NET interfaces require a specific interface module and an

NIS module (the INIIL02 module requires two NIS modules).

Two captive latches on the front-mounted faceplate secure the

module to the MMU card cage. There are 16 LEDs on the face

plate that display error codes or event/error counts.

Each NIS module connects to its INFI-NET communication

loop by a cable connected to an NTCL01 Communication Ter

mination Unit or NICL01 Communication Termination Module.

INTERFACE DESCRIPTION

The INFI-NET to INFI-NET interfaces are the INIIR01 INFI-NET

to INFI-NET Remote Interface and the INIIL02 INFI-NET to

INFI-NET Local Interface. The INNIS01 Network Interface Slave

Module is the front end of the INFI-NET to INFI-NET interfaces.

It is the intelligent link between a node and the INFI-NET loop.

The network interface slave (NIS) module and an INFI-NET to

INFI-NET transfer module create a specific node interface.

The INIIR01 INFI-NET to INFI-NET Remote Interface is made

up of the NIS module and the INIIT12 INFI-NET to INFI-NET

Transfer Module. This interface is a node on a central loop that

can communicate to an interface node on a remote satellite

loop (two interfaces are required, refer to Figure 1-1). Bidirec

tional communication from the central loop to the remote sat

ellite loop is through standard RS-232-C ports. The INFI-NET

to INFI-NET remote interface can support hardware redun

dancy. Refer to Appendix E for information on hardware redundancy.

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.
