1st Automation structure
Touch display – Central PLC – Control wiring – Fieldbus –
Remote I/o
Complex wiring systems connected to the central PLC become
unnecessary through the use of touch displays and remote I/Os.
For the first time, the touch display also offers a communication
link to an ERP system. An onsite production manager is no longer
required here, and machine data can now be accessed remotely.
Together with the fieldbus, remote I/Os are used to replace
complex machine cabling. Remote I/Os function at the same time
as data collectors that are interconnected by means of a fieldbus.
These types of architectures are nowadays in widespread use.
They also integrate components such as hydraulic valves. In other
words, each innovation stage integrates more functions such as
a hydraulic or electric drive. The significant feature here is that
for the first time the data from the machine is now fed and made
available to a higher-level system.
2nd Automation structure
Touch display – Central PLC – Control wiring – Fieldbus –
SmartWire-DT – Remote I/o
This automation structure is basically the same as the previously
described structure, however with the key difference that the
use of SmartWire-DT considerably reduces the wiring required
for pilot devices, motor starters and circuit-breakers. For example,
pushbutton actuators, indicator lights, and switching devices
can be fed with the operational current and integrated in the
communication structure via a single SmartWire-DT line. The
clear and simple structure therefore shortens also the test and
commissioning phase as well as the wiring required. SmartWire-
DT is connected via gateways to Profibus or CANopen fieldbus
systems. Compared to the overall engineering design, the
requirements in the SmartWire-DT line are considerably reduced.
Other components such as sensors and actuators are primarily
connected via remote I/Os to fieldbus systems.
3rd Automation structure
hmI/PLC with integrated SmartWire-DT – Fieldbus –
Remote I/o
The touch display PLC replaces the central PLC. A gateway
to the fieldbus is no longer required; the SmartWire-DT line is
connected directly to the HMI-PLC. Operating data from the motor
feeders, such as motor current, thermal motor load, switching
states, trip indications such as overload, short-circuit, phase
loss, is transferred via SmartWire-DT to the HMI/PLC. Servo
drives, frequency inverters and some sensors are integrated

The vision – Lean Automation: HMI/PLC – Remote intelligence with SmartWire-DT 3rd party
in the automation structure via standard fieldbuses. Electrical
and hydraulic drives replace the mechanical system and thus
enable flexible production without the need to retrofit mechanical
equipment. The machine operator selects the production
quantities and recipes via a touch display and the machine is
reset automatically. Downtimes and changeover times become a
thing of a past. This complete and fully automated total solution is
already available from Eaton.
The vision – Lean Automation
hmI/PLC – Remote intelligence with SmartWire-DT
This visionary “lean automation” structure eliminates the need
for remote I/Os and any signal wiring to sensors or actuators.
“Lean connectivity” brings SmartWire technology directly into the
devices. The structure consists of an HMI/PLC with integrated
SmartWire-DT and components with remote intelligence. Starting
from the display, SmartWire-DT connects pushbutton actuators,
indicator lights, switchgear right up to the sensors. Frequency
inverters and safety systems, as well as hydraulic and electrical
drives are integrated via SmartWire-DT. “Lean automation” finally
brings together the world of hydraulics and the world of electrics
in the automation world. To strengthen this vision, Eaton is also
offering the SmartWire-DT technology to other manufacturers
for the integration of their own components in SmartWire-DT.
Manufacturers can thus obtain an implementation set to develop
SmartWire-DT slave components.
Summary
A “lean automation” solution, consisting of SmartWire-DT and
HMI/PLC technology “slims down” control cabinets, simplifies
the wiring, increases data transparency, reduces engineering
and commissioning requirements, increases performance and
reduces the cost requirements, as well as bringing fewer fault
sources and greater flexibility for modular machine concepts. In
order to also make these significant benefits transparent in terms
of expenditure, Eaton has developed its own software tool that
compares different automation concepts with the Eaton “From
lean connectivity to lean automation” solution. All prospective
collaborators and third party manufacturers are called upon to
take part in Eaton’s vision through discussions and/or their own
components.
