Autonomy

PC-Based Systems Daytronic "Front-End" Systems
  • Operation is COMPUTER- DEPENDENT

  • Power interruption or software crash halts monitoring and control

  • Completely STAND-ALONE to ensure maximum system uptime; when multiple units are networked, each node operates as an independent stand-alone system

  • All data acquisition and control functions TRANSPARENT TO THE COMPUTER and continue without loss of configuration or data when the computer is down

Universality

PC-Based Systems Daytronic "Front-End" Systems
  • Specific cards limited to particular transducer types and ranges

  • FIXED ARCHITECTURE: The system is tied to a specific computer platform, and requires upgrading with each new computer generation (high potential for rapid obsolescence)

  • Accepts mixed inputs from VIRTUALLY ALL TRANSDUCERS for an exceptionally wide range of measurements

  • Interfaces with VIRTUALLY ANY COMPUTER under any operating system and programming language; positioned for compatibility with new computers as they become available

  • OPEN-ARCHITECTURE LINKAGE makes real-time and historical data accessible via computer-independent third-party software (Autonet, Labview, Lab Windows, Paragon, etc.)

Functionality

PC-Based Systems Daytronic "Front-End" Systems
  • Depends on available computer hardware and software resources; often requires multiple vendors and extensive programming

  • Data displays are dependent on software; simultaneous display of multiple screens normally requires multiple computers, while display modifications usually require halting the process and reprogramming

  • Standard operating firmware means NO PROGRAMMING: Simple English mnemonics initiate user-selected setup and run-time functions; the system can be up and running in a very short time

  • SINGLE VENDOR, single responsibility

  • Larger systems support MULTIPLE INDIVIDUALLY CONFIGURABLE DATA DISPLAYS with adjustable update rates; display formats may be created or modified by the operator even while the measured process is running

Expandability

PC-Based Systems Daytronic "Front-End" Systems
  • Depends on available computer expansion slots (even with an expansion chassis, you can quickly run out of slots!)

  • Addition or replacement of cards entails opening the computer--and all the risks associated with this action!

  • INDEFINITELY EXPANDABLE through addition of mainframe racks and/or networking of individual "on-site" units

  • Quickly and easily RECONFIGURAIBLE IN THE FIELD, with no computer programming; cards can be added or replaced WITHOUT TAKING THE MAINFRAME APART

Connections

PC-Based Systems Daytronic "Front-End" Systems
  • Special transducer connection panels often required, with difficult access and cable hookups

  • Proximity to process sensors limited by computer location and power source; usually requires a maze of cables back to the central computer

  • DIRECT TRANSDUCER CONNECTIONS from rear of instrument, allowing quick disconnect while on-line

  • Remote data collection and control units can be located CLOSE TO PROCESS SENSORS, greatly reducing costly and troublesome cable connections

  • DC-powered units for vehicle operation

Troubleshooting

PC-Based Systems Daytronic "Front-End" Systems
  • Built-in troubleshooting typically not available

  • BUILT-IN HEALTH MONITORING

  • System modularity and ease of access facilitate RAPID DIAGNOSIS AND REPAIR

A/D, Signal Processing & Control

PC-Based Systems Daytronic "Front-End" Systems
  • ALL DATA PROCESSING PERFORMED BY THE COMPUTER; this restricts the computer's time and ability to perform other critical tasks, while adding significantly to the total software overhead and programming demands

  • Critical control response time is difficult to determine because of variable processing speed and other factors

  • SUPPLIES THE HOST COMPUTER WITH FINISHED ENGINEERING-UNIT DATA WHEN (AND ONLY WHEN) REOUESTED SO ALL THE COMPUTER NEEDS TO DO IS ASK FOR IT

  • PROCESSING FUNCTIONS include automatic conversion to floating-point format; maintaining individual multichannel data displays; archiving and playback of historical data; limit checking and alarming; linearization and calibration; cross-channel calculations; analog and digital control outputs (including high-frequency analog output and PID loop control) with precisely determined response times; counter/timer functions; on-line SPC; repon generation; and much more--all completely independent of the computer

Speed

PC-Based Systems Daytronic "Front-End" Systems
  • WITH CONVENTIONAL PC'S, YOU TRADE OFF SOFTWARE OVERHEAD FOR FINISHED-ANSWER THROUGHPUT

  • Unless you're exclusively interested in high-speed dynamic analysis, a fast sampling rate yields "raw data" only; to produce an acceptable "finished answer rate--especially when a large number of channels must be processed--typically consumes 25% to 100% of the PC's time and resources, and also has an adverse effect on the screen update rate

  • FINISHED-ANSWER PROCESSING (INCLUDING DATA DISPLAY AND REAL-TIME PROCESS CONTROL) MAKES NO DEMANDS AT ALL ON THE HOST COMPUTER

  • For systems with over 60 measurement inputs or with complex calculations, throughput of finished-answer data is typically FASTER than the comparable PC-based system--and this includes computation of true average of highly dynamic variable--with no display update delay

Accuracy

PC-Based Systems Daytronic "Front-End" Systems
  • Electrically noisy environment limits accuracy of sensitive input signals and the reliability of associated control functions

  • Sampling of dynamic signals with unrestricted input bandwidth can produce significant aliasing errors

  • Lack of specific calibration functions requires user to improvise his own techniques, thereby introducing overall measurement inaccuracies

  • Features the proven reliability of TRUE ANALOG SIGNAL CONDITIONING, with accurate, remotely sensed excitation and with separate amplifier, 3-pole filter, and selectable digital filter for each input

  • LOW-NOISE FRONT-END ENVIRONMENT ensures drift-free measurement and dependable control action

  • Optional synchronous data collection yields VIRTUALLY ZERO TIME SKEW

  • Accurate BUILT-IN CALIBRATION for a wide variety of sensors
