Introduction

1-2 ADAM 4000 Series User's Manual

Introduction

1.1 Overview

The ADAM Series is a set of intelligent sensor-to-computer interface

modules containing built-in microprocessor. They are remotely controlled

through a simple set of commands issued in ASCII format and transmitted

in RS-485 protocol. They provide signal conditioning, isolation, ranging,

A/D and D/A conversion, data comparison, and digital communication

functions. Some modules provide digital I/O lines for controlling relays

and TTL devices.

Software Configuration and Calibration

ADAM modules contain no pots or switches to set. By merely issuing a

command from the host computer, you can change an analog input module

to accept several ranges of voltage input, thermocouple input or RTD

input. All the module’s configuration parameters including I/O address,

speed, parity, HI and LO alarm, calibration parameters settings may be set

remotely. Remote configuration can be done by using either the provided

menu-based software or the command set’s configuration and calibration

commands.

By storing configuration and calibration parameters in a nonvolatile

EEPROM, modules are able to retain these parameters in case of power

failure.

Watchdog Timer

A watchdog timer supervisory function will automatically reset the ADAM

modules in the event of system failure. Maintenance is thus simplified.

Power Requirements

Although the modules are designed for standard industrial unregulated 24

VDC power supply , they accept any power unit that supplies power within

the range of +10 to +30 VDC. The power supply ripple must be limited to 5

V peak-to-peak, and the immediate ripple voltage should be maintained

between +10 and +30 VDC.

Chapter 1

Connectivity and Programming

ADAM modules can connect to and communicate with all computers and

terminals. They use RS-485 transmission standards, and communicate with

ASCII format commands. The command set for every module type consists

of approximately ten different commands. The command set for input

modules is larger because it incorporates alarm functions. All communica-

tions to and from the module are performed in ASCII, which means that

ADAM modules can be programmed in virtually any high-level language.

RS-485 Network

The RS-485 network provides lower-noise sensor readings, as modules can

be placed much closer to the source. Up to 256 ADAM modules may be

connected to an RS-485 multi-drop network by using the ADAM RS-485

repeater, extending the maximum communication distance to 4,000 ft. The

host computer is connected to the RS-485 network with one of its COM

ports through the ADAM RS-232/RS-485 converter.

To boost the network’s throughput, the ADAM RS-485 repeaters use a

logical RTS signal to manage the repeater’s direction. Only two wires are

needed for the RS-485 network: DATA+ and DATA-. Inexpensive

shielded twisted pair wiring is employed.

Panel/DIN Rail mounting

ADAM modules mount on any panel, on provided brackets, on DIN rails

or may be stacked together.

Introduction

The RS-485 network, together with screw-terminal plug connectors, allows

for system expansion, reconfiguration and repair without disturbing field

wiring.

Protection against the environment

Hardened plastic packing forms the outer shell of every module. Since all

configuration is controlled by software, the module is not designed to be

opened. This greatly enhances resistance against corrosive materials,

moisture and vibration. ADAM modules’ low power requirements help

them to operate in temperatures from 0 to 70oC,and in humidities from 0 to

95% (non-condensing). They’re built compactly using automated SMT

technology so you can pack them into water-tight and explosion-proof

industrial enclosures.
