Information
The Fluke Helios I Computer Front End is a data acquisition
and control subsystem that can be used with any kind of
personal or mainframe computer. The Front End combines a
full range of measurement capabilities with easy
programmability. It includes:
o An RS-232-C and an RS-422 standard serial Interface port
for communication with a host computer.
o A microcomputer with ROM and RAM to provide local
intelligence.
o Six option slots that accept any of a range of measurement
and control modules, supporting a variety of both analog and
digital inputs and outputs. Expansion chassis can be added
to accommodate more up to a maximum of 1500 in the system. A
maximum of 1000 channels can be accommodated if the
Scan/Alarm option is in use.
The Computer Front End is a smart intermediary between a
computer and a real world measurement application. Through a
standard computer Interface the Front End gathers data
about physical quantities and generates control or stimulus
signals.
The Front End is a medium speed, highly accurate measurement
and control system. It can be adapted to a very broad
spectrum of applications, with a capacity ranging from a
single channel in a minimal configuration to 1500 (or 1000
with the Scan/Alarm option) in a fully expanded system.
A microcomputer in the Front End executes commands received
from the host computer, drives the measurement and control
hardware, and sends appropriate responses back to the host.
The command set is a collection of high level instructions,
presented in a readable and easy-to-grasp format.
Channel definition commands select ranges and sensor types.
From then on, automatic signal conditioning and data
conversion take place for sensors as common as
thermocouples, RTDs and strain gauges, or as unique as a
user-defined sensor type. Thus, the Front End responds to a
measurement request command by returning a value in
appropriate units of measurement. Conversely, a channel set
command, which assigns a value to a control output, is
translated into an electrical signal.
