Industrial automation trends
In
the past, factory automation and process control related to plant and machinery
that was big, bulky, static and represented several years, if not decades, of
investment. Industrial automation hardware ranged from programmable controllers
(PLCs) to large distributed control systems (DCS) with a sprinkling of PCs for
interface. Today, the tools of discrete automation and distributed controls are
merging, with PLCs becoming front-end I/O controllers and networked PCs taking
over the DCS environment.
Software
growth arenas of the past were SCADA, data acquisition and HMI simply
emulating the functions of a DCS at a reduced price. Today, those functions are
integrated inexpensively in most equipment, and growth is in the arena of
manufacturing execution systems (MES) software and integration of factory and
business-wide functions and logistics. Tomorrow's software will operate
multi-processor systems to coordinate peer-to-peer I/O and controls.
New
technology is moving too fast, and the rate of change of performance is
increasing too rapidly, to play by the old ground rules. New equipment will be
small, cheap, reliable, flexible, expandable and disposable.
Operation will be intuitive and training quick and effective.
In
a global environment there will be smaller, distributed factories built near the
source of raw materials and dismantled when the source is depleted. Operator
knowledge, training and assistance will be distributed over the Internet.
Coordination of worldwide production and process plants will be through
real-time information networks.
The
Future is here
Formerly,
industrial controls were all hard-wired because wireless connections were slow
and expensive, and there was some mistrust of remotely operated systems that
could be tampered with. Today, wireless links are fast and economical; soon
bandwidth will be plentiful, to connect everything to everything. Also, advanced
encryption technology makes wireless links trusted and advantageous.
At the
local calibration-and-troubleshooting level, the old mechanisms of plugging in
will soon obsolesce as Bluetooth connections proliferate. Instrument technicians
will use wireless personal digital assistants (PDAs). When there is insufficient
capability, the PDAs will link via the Internet to higher levels to download
"advice".
Micro
Electro Mechanical Systems (MEMS) will bring the analog and digital worlds
closer together than ever before-through revolutionary improvements utilizing
semiconductor fabrication techniques to produce miniature sensors, motors,
gears, and actuators. A key benefit of MEMS is not only small size, but also
very low power, allowing more miniature, battery-operated sensors with wireless
connections to be scattered throughout the factory and in the field.
Central
control hierarchies will yield to new self-organizing P2P networks, where
intelligence resides directly in the I/O the sensors and actuators. By these
new standards, today's PLC and PC-based controls and software will seem
ineffective, expensive, and even archaic. Old, deterministic control
architectures will disappear, giving way to CAS (complex adaptive systems). CAS
provides easy expandability to very large systems plus reliability through
redundancy at the I/O level, with unprecedented robustness and systems
effectiveness.
Growth
& Success
The
industrial instrumentation & controls business is at an inflection point.
Old knowledge is widely disseminated and many products have become commodities,
causing a general business decline.
Growth
and success will result for the leaders who recognize the revolutionary
advantages that new technology brings, and for those who have the ability to
provide new products and advances for old and new markets.
