New ExperTune PID Tuner for Windows

October 21, 1994 -- Gerry Engineering's ExperTune DDE Faceplate PID Tuner
for Windows has been judged the easiest system to use - "The 5 Minute
Tuner" - and the only PID tuning program for Windows with a HELP system.
Automatic Tuning is only two steps away and the new SUPER-HELP guides the
user through every step of the process. For unusual applications, the new
TEKDisk feature automatically creates a data disk which can be forwarded
to Gerry Engineering for expert evaluation without charge.

"Tuning software is all we do," John Gerry, the firm's president told us.
"We're one of the oldest and largest in this business with more successful
world-wide installations than any other company. Through our eight years
of experience, our customers have helped us design what they tell us to be
the easiest and most productive tuning software available. It just works!
And maybe that's why our technical support continues to be offered without
charge while competitors may charge hundreds of dollars."

"We guide you through every step of the process," John added, " and it
keeps you in control at all times, avoiding 'phantom' or background
programming. Simply define your loop and click on the Auto-Tune Sequence.
Our new ExperTune for Windows DDE Faceplate offers a single window where
complete management of your PID loop takes place; you can easily change
controller mode, setpoint and output, or download new PID parameters."

The new ExperTune software offers three categories of load tuning,
optimized for process load upsets: Fastest, Fast, and Slow, which
corresponds to optimal, quarter amplitude damping, and 10% overshoot
tuning. A "probable performance increase" routine allows the user to
decide whether to download the new settings. Lambda Tuning matches
response to setpoint changes to a first order lag time constant called
lambda which ExperTune automatically sets to give no overshoot to setpoint
changes while permitting adjustment for faster or slower response.

DDE trending and archiving of data is included to tune any loop from a
windows DDE server. Hysteresis analysis, filtering, power spectral
density, and a host of advanced data editing features are also offered.

ExperTune for Windows is compatible with any software that writes plant
data in ASCII columnar format - DMACS, ExperTune PLC Interface, ExperTune
A/D Converter, Factory Link, The FIX, Genesis, Lab Tech Notebook, Lotus
1-2-3, Paragon 500, ProcessData, Wonderware, Quattro, etc.

Gerry Engineering specializes in PID tuning software for virtually any
controller type. Their other products include ExperTune PID Tuner which
includes a simple direct connection for tuning most PLC's and controllers,
ExperTune A/D Converter which easily gets voltage, thermocouple and RTD
data into your PC, Loop Simulator for off-line analysis of PID loops, and
Cascade/FeedForward Simulator to analyze and tune cascade loops on your
PC.
