Automation & Controls Engingeering Ltd.
Application: Laundry Tunnel processing
machines (wash, rinse, dry, fold)
SoftPLC Processor, Industrial
workstation for HMI/TOPDOC communicating via ethernet. GE Fanuc Series
Motivation: Previous design
using GE 90/70 had limited communications. SoftPLC provided better network
& I/O communications, improved speed and quality, overall was a more cost
Key Features: Systems installed
at Disneyworld and elsewhere.
Schenck - Germany
Applications: Non-contact Wheel Alignment
Hardware: Industrial workstation for custom
data acquisition software & TOPDOC, COMARK Coprocessor for SoftPLC. Phoenix
Contact Interbus I/O
Motivation: Original machines
used PASCAL, customers wanted ladder logic for maintainability. Integration of
proprietary PLC would have been more difficult.
Features: Schenck wrote interface to communicate from their HMI software
to SoftPLC over the PC backplane using SoftPLC's
ONE Programmer's Toolkit.
Systems currently installed at a variety of automotive plants all over the
world. First system installed 7/95.
Frigo France - France
Application: Automotive Fluid Fill &
Brake Test machine
SoftPLC Processor, TOPDOC via COM
on laptop when needed. Phoenix Contact Interbus I/O.
Motivation: Replaced Modicon PLC for control plus a computer
running a test program written in Basic, with a single SoftPLC doing the
control as well as running a custom
TLI to do testing
Key Features: First one installed in 2/94 was the first
SoftPLC controlling I/O in the world.
Additional "like" machines have been manufactured by A'Gramkow, Denmark
utilizing similar technology, with the addition of support for 28 COM ports
(using COMGENIE) for bar code
Polar Cerveciana - VenezuelaApplication: Beer manufacturer - Machine unpacks, washes,
fills, then repacks bottles - 1600/minute
SoftPLC Processor. Used existing
A-B 1771 I/O.
Motivation: Replaced existing PLC-3
and (2) PLC-5/15's to increase performance and simplify application. A-B
announced that PLC-3 was to become obsolete, and PLC-5/15's were also obsolete
Features: Total scan time under 13
msec, even with 16 full racks of A-B I/O.
Sandvik Sorting Systems - KY
Application: High-Speed overnight
envelope sorting conveyors
Pentium PC with A-B 1771 or SLC-500 I/O
Needed to replace SLC-500/PLC-5 because they were too slow. Replaced (2) PLC's
with a single SoftPLC.
CONVEYOR instructions for
sorting algorithm makes SoftPLC even faster!
