MAQ®20 Industrial Data Acquisition & Control System

The MAQ®20 Industrial Data Acquisition and

Control System encompasses more than 25

years of design excellence and quality in the

process control industry. The initial offering in

this high performance and highly flexible system

is a family of DIN rail mounted, programmable,

multi-channel, industrially rugged signal

conditioning input and output modules and

communication modules. Each I/O module has

a 1500Vrms isolation barrier between field-

side and system-side wiring, and some models

offer per-channel isolation. All field wiring ter-

minals are heavily protected against overload,

accidental connection of incorrect signals, and

ESD. Modules mount on the industry standard

35x7.5mm gull-wing DIN rail, and a backbone

mounts within the rail providing power and

communication interconnections between the

communication modules and each I/O module.

One communication module can interface to

up to 24 I/O modules to construct a system

with a maximum of 384 channels that fits

within a standard 19” instrumentation rack!

Processors within each module make this

distributed system extremely powerful.

single-ended input for precise measure-

ment of voltage and current signals; they

also offer 8-channel measurement of five

thermocouple types including accurate cold

junction compensation and linearization.

All channels are individually configurable

for range, alarm limits, and averaging.

- RTD Input Modules interface to 2-wire,

3-wire, and 4-wire sensors including five

RTD types and potentiometers. Modules

offer six channels, each configurable for

range, alarm limits, and averaging.

- Strain Gage Input Modules connect to

full bridge sensors, have narrow or wide

bandwidth filtering and offer four channels,

each configurable for range, alarm limits,

and averaging.

- Frequency Input Module accepts zero-

crossing and TTL signals with frequencies

of 500Hz to 100kHz and provides a DC

stimulus for contact sensors. This module

has four channels, each configurable for

range and alarm limits.

• Analog Output Modules: Process Current

and Voltage Output models drive valves,

perform other crucial process operations,

and provide up to eight channels of output

which can be independently configured

• Discrete Input/Output Modules: Provide

multiple channels of input and output per

module and offer advanced special

functions as well as alarm capability

The System Backbone resides within the

DIN rail used for module mounting and pro-

vides power to and interface between the

communication module and the I/O modules.

Communication Modules are offered in two models covering

standard industrial buses: Ethernet, RS-232, RS-485, and USB. Host

software interfaces to the system using the Modbus TCP or RTU

protocol. When using the Ethernet interface, up to four simultaneous

socket connections are supported and each socket can process up to

four simultaneous Modbus TCP transactions. Serial communications

over RS-232 or RS-485 can be run at baud rates as fast as 921.6kbps.

Another useful feature of the system is the capability to store acquired

data locally for later analysis. Each communication module has an easily

accessible and removable 4GB micro-SD memory card that can be

used to log data from all input modules.

To power the system, a 7-34VDC power source is connected to the

communication module. Regulated and protected supplies within the

module then provide power both to the internal circuits and to all mod-

ules in the system. When many high power I/O modules are used in a

system, load-sharing power boost modules can be installed in standard

I/O module slots to provide the necessary additional power.

Typical at TA = +25°C and +24VDC system power

Analog Input Modules interface to a wide range of standard

industrial sensors and equipment, including volt, millivolt, milliamp,

thermocouple, RTD, potentiometer, strain gage and frequency. Four to

16 channels of input on the modules results in physically small control

systems and low cost per channel. Signal ranges are user selectable

and offered in both differential and single-ended configurations. Chan-

nels can be independently configured and alarms can be set to match

the most demanding applications.

Modules are offered with 4-20mA and 0-20mA process current

output or up to ±10V voltage output with drive capability; they control

motors, drive valves and perform many other crucial process opera-

tions. Up to eight channels of output on the modules results in physi-

cally small control systems and low cost per channel. Output modules

have each field-side channel galvanically isolated from all others to

eliminate common mode signal problems and offer maximum durability.

Signal ranges are user selectable and channels can be independently

configured to match the most demanding applications. Processing

power within each module allows users to enter waveshapes to output

to field devices. Power-on delay and default channel states guarantee

proper process performance upon startup and during power interrup-

tions. Field I/O connections are made through a pluggable terminal

block with positions provided for the termination of wiring shields.

input and output per module. Solid state circuits provide or interface to

discrete signals up to 60V and 3A. In addition to standard discrete I/O,

these modules provide advanced special functions including Pulse/

Frequency Counter with or without de-bounce, Waveform Measure-

ment, Time Between Events, Frequency Generator, PWM Generator,

mounting and provides power to and interface between the commu-

nication module and the I/O modules. Standard backbones provide

for one communication module and 4, 8, 16, or 24 I/O modules. The

longest backbone, which accommodates 24 I/O modules, fits in an

industry standard 19” rack. Each backbone utilizes a pluggable con-

nector system on each end such that varying system channel counts

can be configured using the standard backbones. As a result of this

pluggable system, the main part of a system, including the commu-

nication module, can be installed in one location while other sets of

I/O modules installed in remote locations connect to the main system

through a wire harness.

Once a system is established with a system backbone and a com-

munication module, system configuration is accomplished by applying

power and installing the I/O modules. These are hot swappable and

true ‘plug and run’. When an I/O module is plugged into any backbone

position, the communication module automatically recognizes that it

has been added to the system, registers it in the system configuration

record, and makes it immediately available in the ReDAQ® Shape for

MAQ®20 host software for use in data acquisition and control. Simi-

larly, when a module is removed from any backbone position, the com-

munication module recognizes that it has been unplugged, removes it

from the system configuration, and disables it in the ReDAQ® Shape

for MAQ®20 software.

ReDAQ® Shape for MAQ®20 Software

Dataforth offers ReDAQ® Shape for MAQ®20

software as the easiest and most efficient devel-

opment tool for use with the MAQ®20 Industrial

Data Acquisition and Control System. This out-of-

the-box software enables users to create, save,

and open graphical user interface projects for test,

process, data collection and data analysis applica-

tions. Built-in functions in the Acquire and Analyze

panels are pre-configured and can be used with-

out setup. Just three easy steps are required to

create data acquisition and control projects using

18 high quality tools and powerful MAQ®20 func-

tions. These projects are developed and executed

in the software’s Presentation panel.

ReDAQ® Shape for MAQ®20 software also

provides the most effective way to configure and

customize MAQ®20 functions for specific applica-

tion requirements. The toolbox tools are easily

moved, re-sized, cut, copied, pasted, and deleted.

The main screen of ReDAQ

shows a representation of the system inclusive

of the communication module and any installed

I/O modules. This graphic is updated as I/O mod-

ules are added to or removed from the system.

Modules can be given unique identifiers, and I/O

module channels can be assigned tag names to

represent process variables they control. These

Shape for MAQ®20

identifiers and tag names are propagated

throughout the software anytime these modules

and signals are used.

In contrast to other graphical software environ-

ments, ReDAQ® Shape for MAQ®20 software

has a very short user-learning curve. It is

based on programming tools incorporated from

Microsoft Visual Studio® and National Instruments

Measurement StudioTM, ensuring its ease of use

and integrated, across-the-board applicability for

data acquisition and control applications.
