2 Basics
2.1 Safety information for users
VIPA modules make use of highly integrated components in MOS-Technology. These
components are extremely sensitive to over-voltages that can occur during electrostatic
discharges. The following symbol is attached to modules that can be destroyed by elec-
trostatic discharges.
The Symbol is located on the module, the module rack or on packing material and it indi-
cates the presence of electrostatic sensitive equipment. It is possible that electrostatic
sensitive equipment is destroyed by energies and voltages that are far less than the
human threshold of perception. These voltages can occur where persons do not dis-
charge themselves before handling electrostatic sensitive modules and they can damage
components thereby, causing the module to become inoperable or unusable. Modules
that have been damaged by electrostatic discharges can fail after a temperature change,
mechanical shock or changes in the electrical load. Only the consequent implementation
of protection devices and meticulous attention to the applicable rules and regulations for
handling the respective equipment can prevent failures of electrostatic sensitive modules.
Modules must be shipped in the original packing material.
When you are conducting measurements on electrostatic sensitive modules you should
take the following precautions:
nFloating instruments must be discharged before use.
nInstruments must be grounded.
Modifying electrostatic sensitive modules you should only use soldering irons with
grounded tips.
CAUTION!
Personnel and instruments should be grounded when working on electro-
static sensitive modules.

2.2 Basics - ISO/OSI reference model
The ISO/OSI reference model is based on a proposal that was developed by the Interna-
tional Standards Organization (ISO). This represents the first step towards an interna-
tional standard for the different protocols. It is referred to as the ISO-OSI layer model. OSI
is the abbreviation for Open System Interconnection, the communication between open
systems. The ISO/OSI reference model does not represent a network architecture as it
does not define the services and protocols used by the different layers. The model simply
specifies the tasks that the different layers must perform. All current communication sys-
tems are based on the ISO/OSI reference model, which is defined by the ISO 7498
standard. The reference model structures communication systems into 7 layers that cover
different communication tasks. In this manner the complexity of the communication
between different systems is divided amongst different layers to simplify the task.
The following layers have been defined:
nLayer 7 - Application Layer
nLayer 6 - Presentation Layer
nLayer 5 - Session Layer
nLayer 4 - Transport Layer
nLayer 3 - Network Layer
nLayer 2 - Data Link Layer
nLayer 1- Physical Layer
Depending on the complexity and the requirements of the communication mechanisms a
communication system may use a subset of these layers.
The bit communication layer (physical layer) is concerned with the transfer of data bits via
the communication channel. This layer is therefore responsible for the mechanical, elec-
trical and the procedural interfaces and the physical communication medium located
below the bit communication layer:
nWhich voltage represents a logical 0 or a 1?
nThe minimum time the voltage is present to be recognized as a bit.
nThe pin assignment of the respective interface.
This layer performs error-checking functions for bit strings transferred between two com-
municating partners. This includes the recognition and correction or flagging of communi-
cation errors and flow control functions. The security layer (data link layer) converts raw
communication data into a sequence of frames. This is where frame limits are inserted on
the transmitting side and where the receiving side detects them. These limits consist of
special bit patterns that are inserted at the beginning and at the end of every frame. The
security layer often also incorporates flow control and error detection functions. The data
security layer is divided into two sub-levels, the LLC and the MAC level. The MAC (Media
Access Control) is the lower level and controls how senders are sharing a single transmit
channel. The LLC (Logical Link Control) is the upper level that establishes the connection
for transferring the data frames from one device into the other.
The network layer is an agency layer. Business of this layer is to control the exchange of
binary data between stations that are not directly connected. It is responsible for the log-
ical connections of layer 2 communications. Layer 3 supports the identification of the
single network addresses and the establishing and disconnecting of logical communica-
tion channels. Additionally, layer 3 manages the prior transfer of data and the error pro-
cessing of data packets. IP (Internet Protocol) is based on Layer 3.
Layer 4 connects the network structures with the structures of the higher levels by
dividing the messages of higher layers into segments and passes them on to the network
layer. Hereby, the transport layer converts the transport addresses into network
addresses. Common transport protocols are: TCP, SPX, NWLink and NetBEUI.

tion layer (physical layer)

The session layer is also called the communication control layer. It relieves the communi-
cation between service deliverer and the requestor by establishing and holding the con-
nection if the transport system has a short time fail out. At this layer, logical users may
communicate via several connections at the same time. If the transport system fails, a
new connection is established if needed. Additionally this layer provides methods for con-
trol and synchronization tasks.
This layer manages the presentation of the messages, when different network systems
are using different representations of data. Layer 6 converts the data into a format that is
acceptable for both communication partners. Here compression/decompression and
encrypting/decrypting tasks are processed. This layer is also called interpreter. A typical
use of this layer is the terminal emulation.
The application layer is the link between the user application and the network. The tasks
of the application layer include the network services like file, print, message, data base
and application services as well as the according rules. This layer is composed from a
series of protocols that are permanently expanded following the increasing needs of the
user.

Please regard the allowed environment temperatures:
1 horizontal assembly: from 0 to 60°C
2 vertical assembly: from 0 to 40°C
3 lying assembly: from 0 to 40°C
If you do not deploy SPEED-Bus modules, the assembly happens with the following
approach:
1. Bolt the profile rail with the background (screw size: M6), so that you still have min-
imum 65mm space above and 40mm below the profile rail.
2. If the background is a grounded metal or device plate, please look for a low-impe-
dance connection between profile rail and background.
3. Connect the profile rail with the protected earth conductor. For this purpose there is
a bolt with M6-thread.
4. The minimum cross-section of the cable to the protected earth conductor has to be
10mm2.
5. Stick the power supply to the profile rail and pull it to the left side to the grounding
bolt of the profile rail.
6. Fix the power supply by screwing.
7. Take a backplane bus connector and click it at the CPU from the backside like
shown in the picture.
8. Stick the CPU to the profile rail right from the power supply and pull it to the power
supply.
9. Click the CPU downwards and bolt it like shown.
10. Repeat this procedure with the peripheral modules, by clicking a backplane bus
connector, stick the module right from the modules you've already fixed, click it
downwards and connect it with the backplane bus connector of the last module and
bolt it.

3.3 Installation guidelines
The installation guidelines contain information about the interference free deployment of a
PLC system. There is the description of the ways, interference may occur in your PLC,
how you can make sure the electromagnetic compatibility (EMC), and how you manage
the isolation.
Electromagnetic compatibility (EMC) means the ability of an electrical device, to function
error free in an electromagnetic environment without being interfered respectively without
interfering the environment.
The components of VIPA are developed for the deployment in industrial environments
and meets high demands on the EMC. Nevertheless you should project an EMC planning
before installing the components and take conceivable interference causes into account.
Electromagnetic interferences may interfere your control via different ways:
nElectromagnetic fields (RF coupling)
nMagnetic fields with power frequency
nBus system
nPower supply
nProtected earth conductor
Depending on the spreading medium (lead bound or lead free) and the distance to the
interference cause, interferences to your control occur by means of different coupling
mechanisms.
There are:
ngalvanic coupling
ncapacitive coupling
ninductive coupling
nradiant coupling
In the most times it is enough to take care of some elementary rules to guarantee the
EMC. Please regard the following basic rules when installing your PLC.
nTake care of a correct area-wide grounding of the inactive metal parts when installing
your components.
– Install a central connection between the ground and the protected earth conductor
system.
– Connect all inactive metal extensive and impedance-low.
– Please try not to use aluminium parts. Aluminium is easily oxidizing and is there-
fore less suitable for grounding.
nWhen cabling, take care of the correct line routing.
– Organize your cabling in line groups (high voltage, current supply, signal and data
lines).
– Always lay your high voltage lines and signal respectively data lines in separate
channels or bundles.
– Route the signal and data lines as near as possible beside ground areas (e.g.
suspension bars, metal rails, tin cabinet).

nProof the correct fixing of the lead isolation.
– Data lines must be laid isolated.
– Analog lines must be laid isolated. When transmitting signals with small ampli-
tudes the one sided laying of the isolation may be favourable.
– Lay the line isolation extensively on an isolation/protected earth conductor rail
directly after the cabinet entry and fix the isolation with cable clamps.
– Make sure that the isolation/protected earth conductor rail is connected impe-
dance-low with the cabinet.
– Use metallic or metallised plug cases for isolated data lines.
nIn special use cases you should appoint special EMC actions.
– Consider to wire all inductivities with erase links.
– Please consider luminescent lamps can influence signal lines.
nCreate a homogeneous reference potential and ground all electrical operating sup-
plies when possible.
– Please take care for the targeted employment of the grounding actions. The
grounding of the PLC serves for protection and functionality activity.
– Connect installation parts and cabinets with your PLC in star topology with the
isolation/protected earth conductor system. So you avoid ground loops.
– If there are potential differences between installation parts and cabinets, lay suffi-
ciently dimensioned potential compensation lines.
Electrical, magnetically and electromagnetic interference fields are weakened by means
of an isolation, one talks of absorption. Via the isolation rail, that is connected conductive
with the rack, interference currents are shunt via cable isolation to the ground. Here you
have to make sure, that the connection to the protected earth conductor is impedance-
low, because otherwise the interference currents may appear as interference cause.
When isolating cables you have to regard the following:
nIf possible, use only cables with isolation tangle.
nThe hiding power of the isolation should be higher than 80%.
nNormally you should always lay the isolation of cables on both sides. Only by means
of the both-sided connection of the isolation you achieve high quality interference
suppression in the higher frequency area. Only as exception you may also lay the iso-
lation one-sided. Then you only achieve the absorption of the lower frequencies. A
one-sided isolation connection may be convenient, if:
– the conduction of a potential compensating line is not possible.
– analog signals (some mV respectively µA) are transferred.
– foil isolations (static isolations) are used.
nWith data lines always use metallic or metallised plugs for serial couplings. Fix the
isolation of the data line at the plug rack. Do not lay the isolation on the PIN 1 of the
plug bar!
nAt stationary operation it is convenient to strip the insulated cable interruption free
and lay it on the isolation/protected earth conductor line.
nTo fix the isolation tangles use cable clamps out of metal. The clamps must clasp the
isolation extensively and have well contact.
nLay the isolation on an isolation rail directly after the entry of the cable in the cabinet.
Lead the isolation further on to your PLC and don't lay it on there again!
CAUTION!
Please regard at installation!
At potential differences between the grounding points, there may be a
compensation current via the isolation connected at both sides.
Remedy: Potential compensation line

Never connect the shield of the cable with GND_ISO, as this could
destroy the interface!
Pin 6 (P5V) of the isolated interfaces carries the isolated 5V supply with the respective
ground GND on pin 5 (M5V). You may use this isolated voltage to provide defined static
voltage levels on the signaling lines by means of resistors and ensure that reflections are
reduced to a minimum.
