devices only require a few simple operations to
integrate into the control system. This gives you
the option to transfer data about the state of
the motor feeder and sections of the system to
the higher-level controller. At the Lägerdorf plant
NZM2 and motor starters (reversing starters
and DOL starters) were each used with a PKE
electronic motor-protective circuit-breaker.
SmartWire-DT is based on standard fieldbus
systems such as Profibus DP or CANopen,
thus enabling a simple integration into standard
PLC programming systems (such as CoDeSys
and STEP7) and SCADA systems. Each
slave on the SmartWire-DT is automatically
assigned an address on the gateway at the
push of a button and in the order in which the
slaves are connected. The individual slaves
are not activated until the address is called.
The SmartWire-DT software (SWD-Assist)
supports the user during planning. It offers help
in correctly selecting the function elements,
suggests accessories and carries out plausibility
checks. For network configurations (such as
Profibus configurations) the software can also be
used to create specific device description files
(GSD file) which are then simply imported into
the appropriate programming system.
SmartWire-DT keeps mounting and wiring
requirements to a minimum. The continuous
green SmartWire-DT cable is a striking feature in
the switchboard. It provides the communication
link between the required components.
SmartWire-DT furthermore eliminates the need
for the entire control system wiring – the single
SmartWire-DT cable normally provides the power
supply required. Conventional I/O modules are
also not used since the I/O level on SmartWire-
DT is directly integrated in the switchgear, thus
totally excluding the possibility of faults.
SmartWire-DT therefore opens up the problemfree
control and reading of process data. With
the PKE and NZM this consists of both simple

and independent product sectors
binary data such as switch positions and also
more extensive messages such as causes of
tripping and also analog data such as motor
currents and the thermal load of a motor. The
differentiated transmission of data provides
users with new possibilities in monitoring
and controlling processes. These range from
increased transparency in manufacturing
processes (monitoring) to the early detection
of critical states or failures right through to
preventative maintenance management.

Gerd Sievers, in charge of system planning and engineering at the Lägerdorf
plant, summed up as follows: “We were looking for an intelligent motor
starter for controlling the conveyor belt for our clinker production. We found
what we were looking for at Eaton. The SmartWire-DT system currently
integrated in our switchboards offers us a high level of reliability and secures
product quality. Even more important for us was the fact that SmartWire-DT
enables us to design our process with greater efficiency, transparency
and clarity. If required, it is also possible to exchange components during
operation. We were able to fully implement our switchboard concept with
SmartWire-DT. The host of functions provided exceeded our initial planning
specifications, such as the system-immanent manipulation protection,
the extremely precise diagnostics or the presettable values in the SCADA
system – SmartWire-DT offers us considerable added value.”
