Controls Consulting, Design, Installation and Service
SWFTEC has 44 years of experience in the controls industry
in Dayton, Ohio U.S.A.
the birthplace of aviation.
We also do much more than control systems. Scan down for that.
We can do systems using Pneumatic, Electric, Electronic, Analog and various Direct Digital
technologies. Systems can use Conventional, Fuzzy Logic,
Neural Net, Expert System, Model Based and/or Simulation
Based control methodologies. We do high reliability design.
In the HVAC Controls Market we have experience with systems from
many vendors including:
Johnson Controls Systems -
T6000, JC80, JC85/10, JC85/40, DSC8500, Metasys (Companion, Facilitator, N30, NAE, FX series)
(ASC devices, DX9100, VMA, FX series through current models, N2, BACnet, LON etc.)
Honeywell Systems -
SymmetrE, Accelon, CARE, Excel, LON tools (We have converted many CARE based systems to use
Echelon iLON SmartServers)
Trane Systems -
Tracer, Tracer Summit, PCM, UPCM, MP500 series etc.
Echelon - LON equipment including iLON SmartServers in Web applications. We sell a LON repeater.
Experience using LON, Modbus and BACnet with iLON SmartServers. We have the tools to produce special
applications for the Echelon iLON SmartServers.
Energy Management - Special demand reduction algorithms to minimize loads.
SWFTEC has software production capabilites. We mostly use Visual Basic and
Assembler for our applications. We can also do Apps for Android and Apple
devices. Some of our products include:
SWFTEC Graphic Program Generator
An automatic program generator with many applications.
Build programs by placing symbols on a drawing.
Graphic Program Generation is also called Function Block Programming
SWFTEC Graphic Interface System
A web-browser-like graphic user interface. This program
supports RS232 serial communication to any controller
with an ASCII text terminal type interface. Direct support
for VT100 and teletype modes. Also does http:, ftp:,
TCP/IP, UDP and E-Mail under script control. Has a special
scripting language which makes it easy to customize. A very
powerful Graphic User Interface.
We do special software for special applications. For example
we did the X-ray Spectrometer Lab software and Furnace
Terminal software for the Flowserve Foundry in Dayton.
We have experience with writing Multitasking, Multiuser Operating Systems
We have written a Variable Precision Floating Point Scientific Math Package.
Computer Models and Simulation Here is an example using our software.
Design equipment to work with Industry Standards
We have electronic design and prototyping capability. We have done
several designs which are compatible with Johnson Control's
Most recently we solved the problem of using JCI Metasys ASC devices
on a Facilitator system. We designed a module that acts as a repeater
on the N2 bus but will convert the type designation to match the
system it is on. So Facilitator devices can operate on a Metasys
system or Metasys devices can operate on a Facilitator system.
We have done designs for other vendors equipment such as the
LON Repeater we sell.
SWFTEC can apply embedded controllers to solve your product design,
interface and control problems. We also sell some ready made solutions.
We can utilize a number of different processors but tend to use
Microchip's PIC Processors
for most applications. Some examples include: Special Application PC Mouse Controller I.C.s
and the N2OPEN protocol above
We have done special integrated circuits for the computer interfaces (joysticks) for
the Bridge computers on large ships and our I.C.s are used in PC Industrial Terminals
in petrochemical and pharmaceutical plants all around the world.
Aids for the Handicapped - Special PC Mouse Controller I.C.s
Hardware Design, Mechanisms, Robotics, Interface & Sensing
We have electronic design and prototyping capability. We can also engineer
and build mechanical devices and systems. This includes a wide range of
things including Vehicles and Simple Robots.
We have Aerospace and autononous vehicle design capabilites including
guidance and control systems.
We can do quick design iterations using our 3D printing capabilites.
Virtual Reality Modeling, 3D capture, and Stereo stuff
SWFTEC is developing a line of products for Artificial Vision Applications
including robot vision systems, vision systems for autonomous vehicles and 3D model generating
