RTD Input Termination Module

Bailey DCS Overview

The Net 90 DCS and the INFI 90 DCS are products of Elsag Bailey Process

Automation N.V., now ABB, and are marketed and installed worldwide.

Net 90 and INFI 90

The Net 90 DCS, introduced in the 1980, and the INFI 90 DCS, introduced in

the 1988, are widely used for process control in process oriented plants, in

industries such as pulp and paper, power generation, cement making, glass,

chemical and many others. In these industries the Bailey DCS system are

respected for the high level of process automation reliability that they bring.

Data Highways

All DCS systems on the marketplace rely on a “data highway” for high speed

data communications between all of the distributed components of the DCS

system. Over the life of the Net 90 and INFI 90 product lines, three primary

data highways have been used: Plant Loop , Super Loop and INFI Net.

Connecting to Bailey DCS

The Driver may be connected to any Bailey DCS via a gateway device, variously

called a Computer Interface Unit (CIU), an INFI-NET to Computer Interface

(ICI) or a Plant Loop to Computer Interface (PCI). These interfaces, designed

for connection of external devices to the Bailey DCS, allow the OPC Data Server

to communicate with the Bailey DCS modules.

The CIU type interface consists of three modules:

• IIMLM0l multi-bus loop module

• IIMCP0l/02 multi-bus communication processor module

• IIMCL01 loop termination module 

The IIMLM0l multi-bus loop module, allows communication between the multibus communication

processor module (IIMCP0l or IIMCP02) and the INFINET or Plant Loop communication highway through the termination module(IIMCL01).

Two ribbon cables connect the loop module to the communication processor

module and to the communication loop module terminations. Dipswitches SW1

and SW2 select the node address and ring number of the console.

An IIMKM02 keyboard interface or an IIMRM02 reset module is present in the

multi-bus card cage. The modules provide power-up reset signal and power fault

interrupt on the multi-bus back-plane. 

Cabling for Serial Communications (IIMCP01 & IIMCP02)

The Driver is connected to the IIMCP02 via serial RS-232.

At the IIMCP01/02:

For serial connect the RS-232 cable to the 9 pin D connector labeled PORT-B.

Standard 9 pin RS232 cables can be used (not provided). IIMCP01/02 DIP

switch settings must be correct.

Once installed and verified, the analyzers provide fast and reliable measurements in the field without calibration.

Sensi+ analyzers include ABB's AnalyzerExpert™ functionality, which provides expert operation and insights directly from the device.

Features include built-in self-diagnostics, automatic laser line locking, real-time cross-talk compensation and operating condition monitoring.
