have to shut down the entire machine
by releasing compressed air with a
redundant safety or control dump
valve. Instead, the Numatics 503 Series
valve manifold can be configured
to shut down air and power only to
the group of valves that controls the
machine's motion in the operator's
vicinity. The flexible approach also
significantly reduces safety system
cost and allows machine space to
be saved for other purposes, says
the company. - ASCO Valve, Inc.,

New software for enhanced
corrosion management
This company's new Data Offline
software (photo) provides corrosion-management
personnel with
enhanced analytics and reporting
that enable new levels of insight for
controlling corrosion. The software
is compatible with all offline Microcor,
ER, LPR and Ultracorr ultrasonic
corrosion-monitoring field instruments.
The software package gives
users a comprehensive look at a
total system or plant, while illustrating
the factors that affect corrosion
rates. Imported data from corrosionmonitoring
points and other process
parameters, including laboratory
analysis, inspections and chemical
injection rates, can be analyzed,
correlated and compared. The software
produces time-related graphical
displays of corrosion data, allowing
direct correlation with other factors,
such as temperature and pressure,
for optimal corrosion control. -

This segment coupler provides
speed on Profibus DP
With the basic segment coupler
(photo) - the successor to SK1 and
SK2 - Profibus PA nodes appear as
DP nodes in the distributed control
system (DCS) and can be configured
and diagnosed without additional
tools. The basic segment coupler
provides this
transparency without
any configuration of its own. The simplicity
of this design assists in efficient
generation of big data for optimized
32
process management. At the same
time, both transmission rate and
timing of the two systems are completely
de-coupled. Communication
to the DCS benefits from responses
with zero delay by the PA nodes
at a transmission rate of up to 1.5
megabits/s on Profibus DP. The basic
segment coupler from FieldConnex
supports a high segment count
per cabinet requiring only 20 mm on
the DIN-rail and very low heat dissipation.

Reduce investment and
operating costs with pneumatics
Water supply company Landeswasserversorgung
(Stuttgart, Germany)
employed this company's pneumatic
automation technology for the construction
of the multimedia and activated-carbon
filtering basins in a
new groundwater filtration system.
The automation technology controls
the water flow using pneumatic valve
actuators (photo) and process valves
for regulation and shutoff, as well as
for preventing return flow. The company
installed seven open two-tier
filters in the new groundwater filtration
system. During backwashing of
one multimedia filter, the pipelines
are opened and closed by 10 shutoff
valves, which are actuated by
this company's DAPS pneumatic
quarter-turn actuators. The actuators
are controlled by valve terminals
with a Profinet connection. Overall,
the technology saved Landeswasserversorgung
10% on its investment
and operating costs compared to
electric automation, says this company.
