Overview
The System 200 V is a modular automation system for centralized and
decentralized applications requiring low to medium performance
specifications. The modules are installed directly on a DIN-rail. Bus
connectors inserted into the DIN-rail provide the interconnecting bus.
The following figure illustrates the capabilities of the System 200V:

Components
The System 200 series consists of a number of PLC-CPUs. These are
programmed in STEP5 of Siemens and they are compatible with existing
programs that are executable on the Siemens series 90U through 115U,
STEP7 of Siemens or in accordance with IEC 61131-3.
CPUs that are fitted with integrated Ethernet interfaces or additional serial
interfaces simplify the integration of the PLC into an existing network or the
connection from additional peripheral equipment.
The application program is saved in Flash RAM or an additional plug-in
memory module.
The PC based CPU 288L can be used to implement operating/monitoring-,
control applications or other file-processing applications.
The modules are programmed in C++, Pascal or in accordance with
IEC 61131-3.
The PC 288-CPU provides an active interface to the back panel bus and it
can be employed as central controller for all peripheral and function
modules of the VIPA System 200V.
With the appropriate expansion interface the System 200V can support up
to 4 rows.
In combination with a Profibus DP-Master and -Slave the PLC-CPU's or the
PC-CPU form the basis for a Profibus-DP network in accordance with DIN
19245-3. The DP network can be configured with any configuration tool.
Parameters are saved in a plug-in Flash ROM module.
The module can also be configured directly via the Profibus network by
means of the VIPA software WinNCS when this is used in conjunction with
a Profibus-Master PC plug-in module that is available from the company
Softing. Alternatively, all Profibus modules are available with a plastic FO-
connector.
Other field-bus systems can be connected by means of slaves that can
interface with Interbus, CANopen and DeviceNet.
A large number of peripheral modules are available form VIPA, for
example digital as well as analog inputs/outputs, counter functions,
displacement sensors, positioners and serial communication modules.
These peripheral modules can be used in centralized as well as
decentralized mode.

ISO/OSI reference model
The ISO/OSI reference model is based on a proposal that was developed
by the International Standards Organization (ISO). This represents the first
step towards an international standard for the different protocols. It is
referred to as the ISO-OSI model. OSI is the abbreviation for Open
Systems 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 systems are based on the ISO/OSI reference
model (OSI: Open System Interconnection) 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:
Layer Function
Layer 7 Application Layer
Layer 6 Presentation Layer
Layer 5 Session Layer
Layer 4 Transport Layer
Layer 3 Network Layer
Layer 2 Data Link Layer
Layer 1 Physical Layer
Depending on the complexity and the requirements of the communication
mechanisms a communication system may use a subset of these layers.
Interbus-S and Profibus for instance only use layers 1 and 2. For this
reason the following paragraphs will be limited to a short description of
these layers.

Chapter 1 Introduction VIPA System 200V Manual

Layer 1 Bit-communications layer (physical layer)
The bit-communications layer (physical layer) is concerned with the
transfer of data bits via the communication channel. This layer is therefore
responsible for the mechanical, electrical and the procedural interfaces and
the physical communication medium located below the bit-communication
layer:
• Which voltage represents a logical 0 or a 1.
• The minimum time that the voltage be present to be recognized as a bit.
• The pin assignment of the respective interface.
Layer 2 Security layer (data link layer)
This layer performs error-checking functions for bit strings transferred
between two communicating partners. This includes the recognition and
correction or flagging of communication errors and flow control functions.
The security layer (data link layer) converts raw communication data into a
sequence of frames. This is where frame boundaries are inserted on the
transmitting side and where the receiving side detects them. These
boundaries 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.
Layer 3 to 7
In accordance with Interbus-S and Profibus these layers have not been
implemented on the bus couplers supplied by VIPA.

Communication layers employed by automation systems
The flow of information in a company presents a vast spectrum of
requirements that must be met by the communication systems. Depending
on the area of business the bus system or LAN must support a different
number of users, different volumes of data must be transferred and the
intervals between transfers may vary, etc.
It is for this reason that different bus systems are employed depending on
the respective task. These may be subdivided into different classes. The
following model depicts the relationship between the different bus systems
and the hierarchical structures of a company:
Plant
computer
PPS CAD
Plant-oriented
control computer
manufacturing, stock,
production data
PPS CAD
Machine and control
computer
Peripheral systems. machines, CNC, NC,
controllers (PLC), measuring systems
Peripheral components

Operational layer
Management layer
System layer
Process layer
Sensor / actuator
layer
Factory bus
MAP Broadband
Cellular bus
MAP Carrierband
Field bus
Sensor / actuator

TCP/IP
H1
It is common that very large volumes of data are transferred on the
operational level that are not subject to timing restrictions. However, on the
lowest level, i.e. the sensor / actuator level, an efficient transfer of rather
small data volumes is essential. In addition, the bus system must often
meet real-time requirements on the sensor / actuator level.
It is for this reason that Interbus-S is most suitable as the sensor / actuator
bus for the cyclic transfer of low volume data packets at predefined
intervals.
