|Full service initiative in industrial communications
For many years, the name Gleichmann is synonymous with extraordinary,
farreaching design-in support. Whether in the field of Motor Control, Health
Care, Building Management or Industrial Automation, only one thing counts for
us: “the optimum solution for each customer”. This is embedded in the minds of
all our employees and has gifted us with a unique design competence. In some
particularly expansive segments even our specialists are, now and then,
dependent on external support. One example of this is in the field of industrial
communications. Just the sight alone at some of the following terms is enough to
make some users break out in a sweat: PROFIBUS, DeviceNet, Modbus, Ethernet,
CC-Link, ControlNet, CANopen, Interbus, Foundation Fieldbus, Lonworks,
AS-Interface and Bluetooth. How do I bring all of the topologies used in our
company under one roof? Are there technologies and products, which are equally
suitable for all applications and which once again help me to be able to
calculate the effort and costs? These are simple questions, but simple answers
are not so easy.
Those of you that already have practical experience with industrial
communications networks know the underestimated complexity of this thematic and
the numerous pitfalls lying in wait.
In the run-up to this year’s SPS/IPC/DRIVES 2006 in Nuremberg, Gleichmann has
set itself a goal: to end this dilemma by means of a unique initiative. In
addition to NEC Electronics und Wind River, we have also been able to win over
additional well-known names - like Gleichmann, also members of PROFIBUS
Nutzerorganisation e.V. (PNO) - for a PROFINET partnership. This will, in
future, allow Gleichmann to be the first components distributor to offer all
services and products relating to PROFINET from a single source. One example is
the close partnership with the Technologie Management Gruppe (TMG) in Karlruhe,
Germany. For more than 20 years, TMG questions conventional thinking patterns
and therefore, opens up new chances for sound competitive differentiation, while
at the same time being fast, consequent and results oriented in execution. In
future, Gleichmann customers will, if required, not only have access to our own
internal experts, but also the experienced TMG designers and consultants will be
placed at their disposal for all questions relating to PROFINET.
Together, we will support you with: knowledge transfer and building, technology
customer specific hard and software solutions as well as the preparation for
the necessary certification.
Detailed information about TMG can be found on page 6/7 of this Gleichmann
Newsletter. Our full service concept in the field of industrial communications

|MINICUBE2 – another revolution! ||
In recent years, NEC Electronics’ CUBE tools have
revolutionised the development of microcontrollerbased applications, offering a
combination of marketleading features, innovative functions for developing in
situ and above all low-cost. This range is now further enhanced by the
introduction of MINI-CUBE2, a new fullyfeatured on-chip debugging and Flash
programming development tool with a whole lot more to offer.
MINICUBE2 has 6 key features
- On-chip debugging and full Flash programming functionality
- Single-tool support for 8-, 16-& 32-bit microcontrollers
- Easily upgradeable for any future Flash microcontrollers
- Powered by USB so no external supply necessary
- Just 4.8 cm²!
- Low price!
Let’s now take a look at these in more detail … The on-chip debug (OCD)
peripheral is a common function of NEC Electronics’ latest Flash
microcontrollers, and using this function, MINICUBE2 enables debugging of a
device on the target system itself. Since debugging takes place with the target
device operating on the board, it also makes MINICUBE2 ideal for debugging in
Depending on the target device, MINI-CUBE2 offers an abundance of debug
features, including 2 hardware break points for real-time debugging, 4 ROM area
software break points and 2000 RAM area break points. Run, Run from Here, Run to
Here, Restart and step execution are also included, plus forced break, RAM
monitoring, time measurement, Reset pin masking and writing to memory during RUN
For extra security, a 10-byte code authentication is also provided. Debugging
takes place through one serial function (3 or 4 pins) with user memory space or
through the OCD interface, again depending on the target device. The same unit
offers full Flash programming functionality, suited to both the development
environment as well as mass production. Using a standard programming interface
and parameter file, 3.0 V or 5.0 V power can be applied with either a 4 MHz, 8
MHz or 16 MHz clock. Security setting is also available.
In addition, MINICUBE2 also features a self-testing function to detect faults
and perform maintenance. A single MINICUBE2 unit will support most NEC
Electronics Flash microcontrollers, including the low pin count 78K0S 8-bit
range, the 78K0/Kx2 general purpose and 78K0/Lx2 LCD controller 8-bit ranges,
the V850 All Flash general purpose 32-bit ranges and the brand new 78K0R/Kx3
And in case you get confused, a clever multicoloured LED will tell you
exactly which technology the unit is currently set for! As well as supporting
existing devices, MINICUBE2 has also been future-proofed with the capability to
update the firmware using a simple Web download, so you can be sure that as NEC
Electronics continuously releases new Flash microcontrollers in the coming
months and years, you can keep using the same tool.
With a USB cable included, there is no need to use any other external power
source – simply plug in and either start the debugger to use the onchip debug
function or start the programming GUI to perform Flash programming. To make
getting up and running even easier, an appetiser version of the very latest IAR
Workbench for use with MINICUBE2 is now available to download from the web, with
individual device target boards also available to enable instant evaluation of
NEC Electronics’ Flash microcontrollers using the onboard clock, LEDs, switches
and a universal prototype area.
All of this functionality is provided in an ultra-compact, ultralightweight
tool. MINICUBE2 is just 4.8 cm² and only 30 g, so you can easily carry it in
your pocket if you really want to! And at around onethird of the cost of the
original MINICUBE, which is already well known for being a very low cost tool,
it is now almost impossible to find a reason not to start developing your next
project with MINICUBE2 right now!

HMS – Plug-In Communication Modules for all
|Anybus-CC provides a flexible communication interface for automation
Anybus-CompactCom Anybus-CC) modules are designed to meet the
increasing communication requirements in industrial automation. Automation
devices with an Anybus-CC slot on board can be instantly connected to all major
fieldbus and industrial Ethernet networks.
The Anybus-CC modules are designed similar to a Compact Flash
card, featuring small size, low price and easy integration. These smart cards
provide the performance and functionality level required to meet the
communication demands of intelligent automation devices such as HMI´s, robots,
inverters, instruments and scales.
Saving up to 70% Development Cost
The modules are fully standardized regarding their mechanics
and hardware/ software interfaces. Automation devices with an Anybus-CC slot on
board can use all available modules and achieve instant connectivity to all
major industrial communication standards. Anybus-CC considerably simpli. es the
development work required to implement a multi network communication interface
and is - even in high volumes – an attractive alternative to inhouse developed
For all Fieldbusses and Industrial Ethernet
Anybus-CC modules are intelligent communication option cards.
The complete protocol of the specific network is performed by the Anybus-CC
module. This of. oads the microprocessor of the automation device from all time
critical protocol transactions. Active Anybus-CC modules are based on the Anybus
NP30 RISC microprocessor. NP30 is a powerful multi-network controller which was
developed by HMS to perform the hardware and software tasks of an industrial
network protocol on a single chip. As of October 2006, the Anybus- CC series
consists of solutions for Pro. bus-DP, CANopen, DeviceNet, Modbus-RTU,
Modbus-TCP, EtherNet/IP, USB, RS-232 and RS-422/-485. Further modules for Pro.
net IO, ControlNet, Interbus, Lonworks, CC-Link and Bluetooth are under
development and will be released shortly.
The small but rugged housing is designed for use in
industrial environments. The mechanics include an easy slide-in and reliable
locking mechanism. No specific tools are necessary to install the Anybus-CC
modules and thus they can be installed anywhere in the delivery chain from the
device manufacturer to the end customer. This simplifies logistics, reduces the
stock level and allows easy selection of the desired network interface. The use
of the standard CompactFlash connector reduces price and ensures availability
from multiple sources.
The Software interface (API) between the Anybus-CC module and
the automation device has been fully standardised by HMS. The object oriented
interface method permits a maximum of network independence and
interchangeability. The Anybus-CC host application interface supports both
asynchronous fast serial as well as a Dual Port Ram based parallel interfacing.
High data throughput and low power consumption based on 3,3 Volt technology let
the Anybus-CC modules fit well into all kind of modern automation devices.

Ethernet + Profinet + IRT = NEC ERTEC!
NEC Electronics, in January 2006, launched a new and unique
series of Enhanced Real Time Ethernet Controllers (ERTEC) designed to deliver
class leading real time performance for Industrial Automation equipment based on
The growing demand for reduced cost of ownership, increased flexibility, and
greater control of the factory floor has been driving increasing sales of
Industrial Ethernet devices. The ARC advisory group expects 51.4% CAGR growth in
Industrial Ethernet device sales through 2009.
With the launch of these new ERTEC devices NEC Electronics has positioned itself
as a leading player in the supply of real time Ethernet solutions.
|Why Ethernet for industrial networks?
The organic growth of communications within the factory has
led to a complex network of different standards for the many different areas
within factory and process automation. Upstream (goods incoming) may be managed
by an Ethernet network closely coupled to inventory management, order
management, and accounting systems. The manufacturing floor, however, is most
likely managed by one or more fieldbuses such as Profibus. In addition to a
major fieldbus, industrial networks also may include multiple local buses based
on simple serial protocols like CC-Link or (Actuator- Sensor Interface) ASi. As
such neither communication is compatible with the others or with Ethernet.
Ethernet is the accepted standard for enterprise networks and carries
communications to all parts of an organisation responsible for running day to
day business. Systems based on well renowned databases like SAP and Oracle
regularly aid in management of inventory, order book, and customer relationship.
All of these aspects are held in the enterprise world and are therefore based on
Ethernet however they directly impact manufacturing ef. ciency. If incoming
goods and outgoing goods are managed using Ethernet it only makes logical sense
to manage the industrial manufacturing network in the same way.
In fact manufacturing is the only part of the business that is not based on
Ethernet today. It is therefore not easily accessible from the enterprise
network. In fact easy access is only possible directly from the factory floor.
Accessibility is only part of the argument for Ethernet on the
factory floor. Total cost of ownership can also be greatly reduced through the
use of Ethernet. In today’s fieldbus based systems, installation, wiring, and
maintenance costs are high because specialised knowledge is required to set up
new machinery. This is very unlike the Ethernet world, in which a new piece of
equipment is simply plugged into the ‘Ether’ and is instantly connected to the
others. Set up and programming becomes easier as communication between a PC and
any Ethernet connected device is well known. As a result assembly lines can be
tuned very easily to alter speed or function, orto perform routine maintenance
at very low cost and with minimal disruption to the assembly line itself.
|Performance and flexibility
Machines within assembly lines require precise
synchronisation to ensure maximum throughput. Any delay at any point on the line
causes a delay in the entire process, which could lead to severe cost penalties.
Today, factories use fieldbuses such as Profibus, which 9 ensure that
communications can deliver the performance required to maintain synchronisation.
This is also referred to as real time performance. It is obvious to see the
detrimental effects of introducing TCP/IP data from the of. ce network into the
real time environment of the factory. Although there are significant advantages
to converting the factory to Ethernet, among them the advantage of connectivity
with the enterprise network, it is clear that real time performance, hence speed
of communications, must be taken into account. The two main factors that affect
speed of communication are processing time and transmission time.
Processing time includes the time it takes to identify and
mark data as real time. Transmission time is the time it takes for the data to
get from sender to receiver. Processing time is dependent on the processing
power available from the CPU, as the data is read and labelled as real time by
software. The less work that must be done by software the shorter the processing
time and the faster the data can be made ready for transmission. Transmission
time is most greatly affected by network traffic. The more data that is present
on the network the longer the transmission time.
Profinet – a new wave in industrial
Profinet is an open standard that maximises communication speed by minimising
both processing and transmission time. Processing time is minimised by the use
of a fast ARM9 CPU to process data as quickly as possible. Transmission time is
minimised by dividing the standard Ethernet bandwidth into two channels, one for
standard non real time TCP/ IP traffic and the other dedicated to real time
traffic. Real time traffic is inserted into the standard flow of data at
predetermined times ensuring that this data is available on the network as soon
as possible. The time between real-time ‘slots’ is predetermined and constant,
so deterministic behaviour is guaranteed. This is called Isochronous Real Time
(IRT). The analogy is that of a fast lane on a highway in which only real time
traffic is allowed. Not only is real time performance guaranteed but the
solution is completely compatible with existing Ethernet networks. Standard
TCP/IP traffic can be used in combination with IRT requirements.
Profinet allows for three levels of performance – standard non real time,
soft real time, and IRT. This allows Profinet to span the entire range of
industrial network solutions, from non real time I/O modules to IRT based motion
controllers requiring less than 1 ms cycle time and less than 1 µs jitter. This
wide scope of performance is the reason why many communications standards exist
today within the industrial network. However, Profinet has the potential to
coexist with these standards and also to allow equipment based on these
standards to communicate with the rest of the industrial and enterprise network.
Cost of installation is extremely low as very little systems integration is
required. Because the Profinet network is self managing for IRT traffic, there
are no pre-requisites for the network topology. Maintenance costs are also low
because any tuning or diagnostics can be run from a PC using non real time data.
There is no need to go to the factory floor and no need to interrupt the line.
|ERTEC – enabling deterministic real time performance
The ERTEC device from NEC Electronics delivers the
performance required by Profinet by including an intelligent hardware network
switch on chip that performs the time slicing required for IRT. It creates the
fast lane necessary to guarantee real time performance. NEC Electronics is the
only semiconductor supplier of a device that conforms to all aspects of the
Profinet standard. Reducing the bill of materials for Profinet applications As
well as delivering real time performance the ERTEC range integrates two or four
standard Ethernet ports including the physical layers, which eliminates the need
for multiple linear discrete components – thereby reducing the bill of materials
for Profinet applications.
ERTEC is currently available in two variants, ERTEC200 offering two Ethernet
ports, and ERTEC400 offering four Ethernet ports. Both are based on the Fast
Ethernet (100 Mbps) standard delivering high bandwidth for both real time and
non real time data. Development kits are now available for both variants and
include ten samples of either the ERTEC200 or ERTEC400.
The integration of industrial and enterprise networks is an inevitability
that opens up possibilities for reduced cost, increased efficiency, and
unsurpassed flexibility for manufacturers. Profinet delivers on its promise of
enabling that integration and the NEC Electronics ERTEC device range is the only
sol tion capable of enabling the full range of Profinet functionality.

Bright future for ERTEC and PROFINET in industrial
The total number of installed industrial Ethernet nodes is estimated to
exceed 13 million by 2010. One of the reasons for such an optimistic prognosis
is, among others, new innovative components, such as the ARM9 based Enhanced
Real Time Ethernet Controller (ERTEC) from NEC Electronics.
Wolfgang Wagener, Technical Product Support at NEC Electronics
Europe answers five questions regarding ERTEC and PROFINET:
Where do you see the advantages of PROFINET?
“We see the advantages of PROFINET essentially in three
areas: First of all, there is the high real-time performance. The deterministic
data transfer capability of PROFINET ensures that complex, technical control
functions (motion control) can be completed, while at the same time the
equipment is connected to a classical TCP/IP based network. This is important,
because it will be a future requirement to integrate manufacturing plants with
the IT infrastructure of the company. Only in this way can it be guaranteed that
factories, in a world requiring ever increasing production efficiency, can be
operated and monitored. Secondly, PROFINET is able to operate with all fieldbus
protocols. Because of this, it will be very simple to “see” all equipment in the
Ethernet network. Manufacturing plants can be upgraded step-by-step with
PROFINET bridges, which close the gap between established fieldbus and the IT
infrastructure. Last, but not least, the PROFINET protocol is defined in an open
standard. All manufacturers of automation equipment can be certain that their
PROFINET compliant equipment will operate, without difficulties, with PROFINET
equipment from other manufacturers.”
Why is NEC Electronics committed to
“NEC Electronics’ entrance into the PROFINET market is the
result of our cooperation with Siemens Automation and Drives Group (A&D),
the leading manufacturer in this field worldwide. The activities of both
companies complement each other, in this market segment, in an ideal manner. NEC
Electronics is well-known as one of the most important suppliers of
semiconductor solutions for industrial applications. We believe that we have a
leadership position, particularly in ASIC technologies, and are therefore able
to offer class leading solutions for even the most complex Industrial Automation
PROFINET with ERTEC: how do you assess the chances in
“Excellent. I am convinced that PROFINET will establish
itself as the future de facto industrial communications standard. Nowadays, in
modern manufacturing plants, a high level of flexibility is demanded and not
just from the automobile industry, which pioneered modularized production
methodologies. In the meantime, the demand to be able to upgrade or replace
individual equipment and machines on the production line, without stopping
production, is increasing. The required modularization can, however, only be
obtained by means of “hot swap” capabilities of the equipment. This means that,
in contrast to the current centralized solutions, local intelligence for
communication between the equipment is needed. This is exactly the philosophy
behind PROFINET and ERTEC: the distribution of intelligence and control of
networked equipment in a manufacturing plant. PROFINET provides this flexibility
in a unique way from the programmable logic controller (PLC) to the sensor and
What are the advantages of PROFINET equipment with
“ERTEC enables customers the simplest and most effective
route to PROFINET solutions. This covers the complete spectrum of PROFINET
real-time capabilities from Non Real- Time (NRT) to Isochronous Real-Time (IRT).
Beyond this, ERTEC is not just a piece of silicon: a real-time operating system
(VxWorks) and the most complex portion of the PROFINET software are already
implemented and can be used immediately. This means that, as a rule, the user
only needs to carry out simple adaptation for his specific hardware and can,
therefore, concentrate extensively on the application software.”
How does NEC Electronics support customers with the
use of ERTEC components?
“The technical support from NEC Electronics is recognized by
customers worldwide as first class. It goes without saying that we also support
ERTEC components, in close cooperation with Gleichmann’s product specialists,
with the same high level as for all other standard MCUs and MPUs. This includes,
among others: complete documentation, applications support, technical workshops,
Internet based Q&A service and a FAQ webpage. Beyond this, NEC Electronics
supports complete solutions for industrial automation with 8/16/32-bit MCUs, a
broad range of power MOSFETs, standard and high-speed optocouplers, design
support, applications guides, software IP and first leading development tools.”

Powerful nanophosphate lithium-ion cell
Gleichmann offers an extremely powerful, and at the same time environmentally
friendly, nanophosphate lithium-ion rechargeable battery from the U.S.
manufacturer A123Systems. The ANR26650M1 has a 10x life cycle vs. conventional
lithium ion batteries and allows for much higher power density, or rate of
charge and discharge. The battery has the ability to recharge to 90% of its
capacity in five minutes. 3000 Watts per Kilogram guarantees the highest
performance in the smallest form factor. The new cell, which for the first time
uses a nanophosphate positive electrode (cathode), has a nominal capacity and
voltage of 2.3 Ah, 3.3V. The internal impedance (1kHz AC) is 8 mΩ typical.
Maximum continuous discharge is 70A and pulse discharge at 10 sec is 120A for
each cell. With an operating temperature range of -30°C to +60°C, the ANR26650M1
allows for use in harsh environmental conditions.
A123 nanophosphate lithium-ion highperformance cells do not
use any toxic heavy metals and are therefore, in contrast to nickel cadmium
cells, particularly environmentally friendly. Due to the use of thermally
stable, noncombustible active materials, the ANR26650M1 cell offers a high level
of safety, even without additional protection circuitry. This feature is a
significant distinction compared with conventional cobalt-based lithium ion
cells. Because nanophosphate lithium-ion cells do not require any protection
components, this allows future high performance rechargeable batteries to be
manufactured much simpler than in the past and therefore, also makes them
suitable for low volume production quantities.
