Distributed I/O System

The ControlWave Micro Distributed I/O System (DIOS) is a

remotely mounted housing for the installation of additional

ControlWave Micro I/O modules. The DIOS supports up to

fourteen slots of I/O using the same form factor as the

ControlWave Micro. The DIOS supports installation of most

ControlWave Micro I/O modules. The remotely mounted

DIOS communicates with the ControlWave Micro base unit

through a standard Ethernet connection.

The DIOS contains a CPU module used as an Ethernet

communication engine that is dedicated to

communications between the main processor located in the

ConrolWave Micro base unit and the DIOS unit. The CPU

module in the DIOS unit also includes power fail/recovery

control and battery backed RAM to retain I/O data during

short power outages.

Display/Keypad

An optional 4-line by 20-character LCD display with

adjustable contrast is available with either a 2-button

keypad or a 25-button keypad. Both options are connected

to the ControlWave Micro base unit via a standard CAT5

cable.

The display with the 2-button keypad allows you to view site

configuration and process data on the display. Screens are

organized in a series of lists. You can select a list and then

manually scroll through the data. Additionally, an

automatically scrolling user-defined list of data can be set.

The display with the 25-button keypad performs the same

functions as the 2-button display and also allows you to view

and modify the ControlWave Micro inputs, process

variables, calculated variables, setpoints, tuning

parameters, and outputs. Status controls include the alarm

state, alarm acknowledge, control, and manual (Auto/Man).

Software

The ControlWave Micro is supported by multiple software

packages for programming, system configuration, and

diagnostics.

ControlWave Designer – ControlWave Designer is a fully

IEC 61131-3-compliant programming environment for the

ControlWave Micro. ControlWave Designer includes all five

IEC 61131-3 process languages for batch, continuous, and

discrete control: Function Block Diagram, Structured Text,

Sequential Function Chart, Ladder Logic Diagram, and

Instruction List.

ControlWave Designer includes an extensive library of more

than 200 basic IEC 61131-3 functions and function blocks

common to many IEC 61131-3 based products. These

include:

 Flip-flops, Counters, and Timers

 Ladder diagram functions – coils and contacts, etc.

 Numerical, Arithmetic, and Boolean functions – Sine,

Cosine, Add, Sub, Square Root, And, Or, etc.

 Selection and Comparison – Min, Max, Greater Than,

Equal, Less Than, etc.

 Type conversions – Integer to Real, Boolean to Word,

etc.

ACCOL III – In addition to the basic functions and function

blocks, ControlWave Designer brings the benefit of over

twenty years of SCADA and plant control experience in

Emerson’s ACCOL III function block library. ACCOL III

includes over sixty function blocks valuable for use in oil and

gas, water and waste water, and process measurement and

control applications. The ACCOL III library includes function

blocks for:

 Average, Compare, Totalize

 Scheduling and Sequencing

 PID and Lead/Lag

 AGA gas flow and liquids calculations

 File handling

OpenBSI – Emerson’s OpenBSI (Open Bristol System

Interface) is a set of network setup, communication

diagnostic, and data viewing utilities that provide access to

both ControlWave and Network 3000 controllers and RTUs.

At the core of OpenBSI is a communication interface

through which other applications communicate. OpenBSI

supports both serial BSAP protocol and Ethernet Internet

Protocol communication to ControlWave RTUs and

controllers.

ObjectServer – OjectServer is an OPC-compliant server that

provides direct communication to the ControlWave family

of controllers, RTUs, PLCs, and flow computers through the

OpenBSI communications interface. It supports serial multi-

drop, remote telemetry, and Ethernet communication

networks. Unlike traditional OPC servers, ObjectServer is

designed to provide reliable access to RTUs that are
