RFID, BARCODES & MOBILE SOLUTIONS:
PATHS TOWARDS INTELLIGENT MAINTENANCE
The intelligent maintenance concept has not lost any of its relevance and was
intensively discussed in all its facets at the "RFID, Barcodes & More"
conference. Technical details, single solutions and the interaction with co-
workers during an introduction of RFID all had their place at the event.
This insight report introduces current
developments in intelligent maintenance which
both users and providers are currently involved in.
The first article, a conference report, examines to
what extent intelligent maintenance has
established itself. It focuses on RFID technology
which, however, is still uncertain to flourish in wide
areas of all industries. The second article examines
the relationship of RFID to barcodes. The third
article details data collected in our study and
clearly supports the trend that the use of RFID is
increasing. The report concludes by including
experiences that have been gathered in practice.

However, the practical experience from recent
years shows that the hype was not entirely
unfounded.
Opportunities to simply optimise existing processes
are limited. For example, it is impossible to
completely avoid errors in the transmission and
identification of assets in manual maintenance

possible.

COEXISTENCE OF BARCODES AND RFID
Intelligent maintenance is not the domain of a single technology. RFID and
barcodes both have their own advantages. In practice it is about finding the
right solution for a company; barcode, RFID or another alternative.
RFID was only one aspect of the intelligent
maintenance conference. Frank Matheußik from
NBB Netzgesellschaft Berlin-Brandenburg and
Marian Pufahl of SD&C presented a choice of
mobile workforce management systems offering a
choice of RFID and barcodes. Rainer Brenk-Ortolf,
head of the department of mobile business at
Begis mbH also dealt with the differences between
RFID and barcodes. The consensus among the
conference participants was that RFID will not
replace barcodes. Each have their places. The first
question is always what should be achieved and
what solutions are most suitable. Depending on
the answers to those questions, different
technologies can be considered. Frank Matheußik, NBB Netzgesellschaft Berlin-Brandenburg mbH
& Co. KG, and Marian Pufahl, IT Consultant, SD&C Solutions
Development & Consulting GmbH
As Rainer Brenk-Ortolf of BEGIS mbH mentioned
however, it is clear that there is a growing interest
in RFID. One reason for this is the range of
possibilities enabled by use of RFID solutions. In
particular, recording information on assets’ RFID
tags is of interest to maintenance workers, who
usually have to work with offline solutions. And in
harsh industrial environments RFID offers a clear
advantage over other solutions due to its
robustness.
Despite this positive development RFID has not yet
widely established itself. The interest is there but
many companies shy away from RFID deployment
because of lack of experience. The costs of RFID
are also viewed critically however; this is not the
main reason why users decide against RFID. Rainer Brenk-Ortolf, head of department Mobile Business,
Begis mbH
Unlike five years ago, many providers of RFID
solutions and technology can now provide
references from maintenance departments. The
choice of a competent implementation partner will,
in future, be even more important.

5. STUDY
AUTHOR Jörn Grote
RFID USAGE IS INCREASING
Mateus Siwek of T.A. Cook introduced the first results of a recent best practice
study about the use of RFID in maintenance. The results of the study clearly
show that RFID use is increasing in maintenance.
For T.A. Cook’s RFID Best Practice study around
350 interviews were conducted, 73 of which were
with companies that currently use RFID in
maintenance The number of RFID projects
starting up has significantly increased over recent
years. Only eight percent of all RFID projects
began between 2000 and 2005 whereas in the
three years between 2005 and 2008 44 percent of
all current RFID projects started. Between 2008
and 2010 another strong increase is visible.
Introduction of planned RFID projects
Of those companies not currently using RFID in
maintenance almost half (45%) of them are
planning projects. Of these, 65 percent have
concrete plans for the use of RFID in the next five
years.

impression.
The question of processes is also of particular
importance during the introduction of RFID. One
approach is simply to let certain manual work
processes be taken over by RFID. However, the
process remains unchanged and it does not take
advantage of the full potential for efficiency
improvement. If RFID is introduced in this manner
the value achieved remains far below expectations.
Expansion of existing RFID projects
To actually exploit the full efficiency savings,
companies should conduct a process analysis and
clarify how the process can be improved. From this
the requirements for the technology can be
effectively derived. The search and selection of

consideration.
One of the biggest changes that the introduction
of RFID makes is a significant improvement in the
database. This enables proactive maintenance
processes that, due to previously inadequate
databases, could only be reactive before. For
example, thanks to an improved database failure

failures as needed.
"RFID BEST PRACTICE":
RFID USAGE IN MAINTENANCE
Although the possibilities of implementing RFID solutions are now well known, many
companies still have questions. Especially in the field of maintenance, there is little
information available. This study aims to close this gap in the future.
The study answers the following questions:
» What benefits do companies generate by using RFID in maintenance?
» What RFID solutions are available?
» How expensive are RFID projects and applications?
» How fast can RFID solutions be installed?
» What challenges arise during the implementation of an RFID project?
» What maintenance applications or processes is RFID used for?
» How are business processes changed by introducing RFID?
» What are the prerequisites for a successful RFID implementation?
» What technologies are suitable for RFID solutions?
A large part of the study addresses case studies that show specifically the use
of RFID in maintenance. It offers the maintenance industry a practice oriented
set of examples for practical implementations. The study offers the reader
the chance to assess the feasibility, cost estimation and cost-benefit analysis
of RFID implementations. To support this there is a study document and a
cost calculation tool enclosed.

MAINTENANCE CUSTOMERS AS A TARGET GROUP
RFID Providers have recognised that maintenance teams represent an
important target group. Many requirements for which a few years ago there
were no suitable products are now covered by the providers’ product
portfolios.
A few years ago maintenance managers had
difficulties finding tailored solutions to suit their
needs; but today the situation has now changed.
In particular, RFID tags used to be more tailored
to the needs of trade and logistics than the harsh
environmental conditions in industry. Attaching
RFID tags to metal surfaces presented problems in
the past as this interfered with reading data.
However, several of today’s solution providers
such as Meshed Systems, microsensys, Smart-Tec,
TNB an others now supply RFID tags that function
without problems on metal surfaces. Almost all
manufacturers of RFID tags currently offer

variations to suit heavy industries. These work in a
wide temperature range and are protected from
dirt, dust and liquids.
Maintenance teams also require ATEX certified
RFID tags. These are already available from
manufacturers such as Tectus, microsenys and
Trovan. At the conference, however, it was noted
that these RFID tags only have an ATEX category
2 certification. For practical application, ATEX
category 1 certified RFID tags are necessary but
not yet available.
In addition to the RFID tags, mobile readers
dominated most discussion themes. An array of
very different experiences was made using PDAs, Exhibition stand of mircrosensys GmbH
cell phones and tablet PCs. Each of these variants
had their advocates. One user said that given the
small size of the keys only the tablet PCs are
practical. For other users, these were not
successful because of the weight and size.
Users’ experience indicates that the choice of
reader should be made in consultation with
employees. It is the employees that ultimately use
the equipment and thus guarantee the success of
the project.

INNOVATION FROM PRACTICE
The further development of RFID technology in maintenance is not only being
driven by the suppliers. Users also initiate the development of new products
motivated by their needs or ideas and from their use of the technology.
The many demands on maintenance require
constant innovations. If the RFID tags do not
match the specific needs of a user, they often
develop a customised solution in collaboration with
the provider. One example was a collaboration
between Lufthansa, Hartig and the Frauenhofer
Institute for Integrated Circuits, which produced
the first air transport approved RFID tag. This
transponder also works outside the cabin and is
used for permanent identification of aircraft
components.
Other solution providers also reported that
collaborations between users and providers led to
marketable, competitive RFID solutions.
V-RFID usage in practice
Ideas for improvements and suggestions for
further applications often come directly from
practice. Once the employees are convinced of the
advantages of RFID technology, they often provide
useful information for further development. At
Evonik, for example, normal RFID tags were
developed further into visual RFID tags. The idea
that it might be possible to see the information on
the RFID tags without a reading device led to this
new development. This “V-RFID” displays basic
information about the asset it is attached to. They
can be used for activating electrical systems or for
periodic inspections and maintenance. Evonik
plans in the future to offer the V-RFID as a distinct
product.

Seven of the 20 presentations and discussions at the conference dealt in part
or completely with the practice of mobile maintenance. As the “RFID Best
Practice” study shows, the greatest interest both for current and future users
lies in mobile solutions.

LEGAL ASPECTS RAISE QUESTIONS
One topic that was of great interest for many visitors to the conference was
the legal side of RFID use. What statutory documentation requirements are
there and how does RFID data relate to data protection?
One advantage of RFID is the improved control of
activities carried out by a maintenance engineer.
There were different views amongst the
conference participants on whether and to what
extent these readings meet the legal
documentation requirements of inspections. Some
users reported experiences showing that RFID
readings are not an acceptable solution for legal
documentation. They continue to produce a
written and signed document as a form of
evidence. Other users reported that their legal
departments had decided that an RFID solution’s
records sufficed as proof of statutory inspections.

Xploy
Another difficult issue is employee monitoring.
Theoretically, RFID solutions offer an exact insight
to what staff members did at what times.
However, from a data protection point of view this
is very dubious. In such cases unions can claim
that the accurate performance monitoring of
employees is not possible. The discussions
amongst the conference participants showed that
the approaches differ toward internal and external
employees. More data is collected on external
employees to enable more accurate invoicing. In
this context the question arose about where to
draw the line between internal and external
employees.
The lively discussion in the plenum made it clear
that all questions concerning the legal aspects of Reiner Pape, mechanics planning, Roche Diagnostics GmbH
all usage of RFID solutions are far from being
answered.
