excom – Connecting to the Industrial Internet of Things

Future-proof thanks to parallel data

access
Parallel data access technology brings IIoT
to the process world. The data is routed
beneath the control system level to a par-
allel IT structure. This ensures that control
systems and process control are left un-
touched. Outside of these systems, the data
can provide valuable information about
efficiency and determine the prospective
probability of failure of components. The
increasing operating time of a valve closure
may for example indicate corrosion or the
formation of deposits. The findings from
these analyses are routed on the operation-

DTM for excom®

The modular excom DTM enables you to

manage the many different functions of the
I/O system. The individual components are
arranged in the “Rack”, “Module,” “Channel”
and “Connected device” levels in an FDT
frame. Using this hierarchy the user can
click on the individual assets directly via a
browser.

Diagnosis and identification

Another two useful functions of the DTM

are the “Diagnosis” and “Identification”
dialog windows. The channel faults of the
periphery are displayed in the Diagnosis
view. Any faults that have occurred are
indicated in plain text with the channel
number. The corresponding terminals
are shown in red. The Identification view
supplies the data required to manage the
system such as data type, order number,
batch code, version states and other device
information.

excom – Individual and Standard System Solutions

System solution benefit

Turck can also supply on request fully

pre-assembled excom control cabinets, ei-
ther as standard variants or with additional
fitted components to your specifications.
This has two clear advantages:
■ You will receive system approval for the
entire cabinet.
■ You will receive proof of intrinsic safety
for the complete
system.

No new approval required even for

expansions

The entire system is approved for the

appropriate Ex areas. Thanks to the system
approval, users can flexibly replace or
even add gateways or I/O cards. Plant
operators can carry out any necessary
re-evaluation of temperature values
themselves in the housing without
the need for an external test
body.

TEPS (USA)
Turck Mechatec and TEPS (Turck Engi-
neered Packaged Systems) offers complete
electrical system solutions to customer
specifications for all areas of industrial
automation. The Turck subsidiary can also
assemble excom control cabinets – either
in a standard configuration or individually
to customer specifications.

As a service provider Turck Mechatec places

great importance on customer service.
Turck mechatec has already implemented a
wide range of solutions for several cus-
tomers in all major industrial sectors. The
products and systems have been tried and
tested in a several different projects and
application conditions. Depending on the
project, the factory acceptance test (FAT)
can be carried out directly at Turck. The
benefit: You only have one contact partner
for your turnkey I/O system.
