About this manual
This manual describes applications of the CP143plus and CP143 TCP/IP modules. These modules
are plug-compatible with any PLC (AG-115U trough AG-188U) and do not require forced air
ventilation. The standard handling modules (SEND, RECEIVE) that are supplied by Siemens may
be used for TCP/IP task processing by the PLC. The description of the handler modules is contained
in the respective manuals available from your CPU.
The application of the two modules is described separately in this manual. The different chapters0
describe the H1-elements first, followed by the TCP/IP-specific elements.
Due to technical progress the illustrations of modules contained in this manual may differ from the
original.

1 Introduction
1.1 Safty and handling precautions for the user
1.1.1 Handling electrostatically sensitive modules
The modules produced by VIPA carry MOS-VLSI components. These components are highly
susceptible to high voltages that may be caused by electrostatic discharges.
These modules bear the following symbol to highlight the sensitive nature of the components:
This symbol is attached to the module, module carriers or on the packing material and indicates that
the module is sensitive to electrostatic discharge.
Modules that are sensitive to electrostatic discharges may be destroyed by energies and voltages that
lie far below the threshold of human perception. It is possible that damaging voltages may occur if a
person who has not been discharged handles a module that is electrostatically sensitive. The
resulting damages to the components will seriously impair the operation of the module or render it
unusable. Modules that have been damaged in this way are rarely recognized immediately. In many
cases the error becomes apparent only after the module has been operating for a while.
Components that have been damaged by an electrostatic discharge may exhibit temporary
malfunctions when they are subjected to temperature variations, shock or changes in electrical load.
The only effective method for the prevention of damages to modules that are sensitive to
electrostatic discharge is the use of protective gear and the strict adherence to the respective rules.

Safty and handling precautions for the user CP143 H1 / TCP/IP manual
1-2 Rev. 00/07
1.1.2 Shipping electrostatically sensitive modules
Modules to be shipped must be packed in their original container. You may also wrap additional
conductive material around modules that are about to be shipped. Conductive material comes in the
form of antistatic foils or metallized enclosures.
Some modules may contain a battery. Please ensure that the conductive
packaging does not come into contact with or short out the battery.
1.1.3 Tests and modifications to electrostatic sensitive modules
Please not the following when testing modules that are sensitive to electrostatic discharge:
• Any floating instrumentation must be discharged for a short period.
• Any test instruments must be grounded.
Please use a grounded soldering iron when you implement modifications to modules that are
sensitive to electrostatic discharge.
It is important that the person as well as the test gear and tools are grounded
properly when modules that are sensitive to electrostatic discharge must be
manipulated
.

2 Communication protocols
2.1 H1 protocol
The Industrial Ethernet H1 LAN provides the basis for the implementation of large, high-tech,
decentralized automation systems. Industrial Ethernet H1 is the complete solution for the
implementation of large, open networks between the different departments of a company.
Compatible devices include:
• PLCs 115, 135, 150, 155
• programmers PG 685, PG 730, PG 750, PG 770
• computers
• other PLCs
The Industrial Ethernet H1 LAN may be used in the following applications:
• central control and supervision of production lines
• monitoring and communicating the status of machines
• management information
• production statistics
• the transfer of large amounts of data
• remote programming of PLCs
2.1.1 Structure of Industrial Ethernet H1
The Industrial Ethernet H1 LAN consists of separate segments. A single segment can support up to
100 terminal devices (PLCs, computers) and its length may be up to 500 m. Individual segments
may be linked by means of repeaters. A maximum of 2 repeaters may be placed between any two
terminal devices.
Repeaters may also be used to construct so-called remote-repeater-configurations. This combination
requires two repeaters and two additional Industrial Ethernet H1 transceivers.
The LAN cable may either be the triaxial cable (yellow cable) or the thin ethernet-cable
(cheapernet).
Triaxial cable:
All terminal devices or repeaters must be connected to the transceivers by means of a drop-cable
(plug-in cable 727-1) (max. length 50 m). The connection between the bus cable and the transceiver
is provided by coaxial plugs. A terminator is required at both ends of the bus cable.
A transceiver on the triaxial cable may be connected to a multiport repeater that can support up to 8
terminal devices.
Thin-Ethernet:
Terminal devices are connected directly to the cable, that is transceivers and drop-cables are not
required. The bus cable is connected to the module by means of BNC plugs. A terminator is
required at both ends of the bus cable.

H1 protocol CP143 H1 / TCP/IP manual
2-2 Rev. 00/07
2.1.2 Operation
The Industrial Ethernet H1 LAN (in conformance with the Ethernet system standard) employs a
random access technique: every terminal device accesses the bus when required. Access to the bus
is co-ordinated by a CSMA/CD (Carrier Sense Multiple Access/Collision Detection) mechanism:
every terminal device “listens”on the LAN and accepts transmissions that match its own address.
Terminal devices can start a transmission only if the bus line is not engaged. Should two terminal
devices initiate a transmission simultaneously, they detect this event and stop transmitting. After a
random delay time they will restart the aborted transmission.
The programmers PG 685, PG 730, PG 750 and PG 770 may be connected directly to the Industrial
Ethernet H1 by means of a transceiver. You may then remotely modify the program of any PLC that
is connected to the LAN. The 923C co-ordinator or the programming multiplexer can also be used
to program a number of modules via a single connection.
The user services of LEVEL 4/4a (handler modules or libraries for PC-modules) are also available.
2.1.3 Structure and operation of the PLC interface
A dual-port RAM connects the CP143 H1 / TCP/IP directly to the back plane bus-LAN. At the PLC
the dual-port RAM is available as a standard-CP-interface with 4 tiles. Any H1 data traffic is
conducted via standard handler modules (SEND and RECEIVE).

2.2 TCP/IP protocol
The TCP/IP protocol was an integral component of the Berkeley UNIX version 4.2 and as such it
became a de-facto standard in local-area networks. Many manufacturers of workstations have since
opted for the ethernet - TCP/IP -UNIX combination. All hardware systems that are currently of
importance support versions of the TCP/IP protocol. This applies equally to the low-end PC, the
typical mini-computer, right through to mainframe computers (the TCP/IP protocol has been
implemented on IBM systems as well) and also to special purpose computers like vector processors
and parallel processors. It is for this reason that TCP/IP is often used when heterogeneous systems
must be linked.
Using TCP/IP it has become possible to implement comprehensive open networks linking different
departments within an organization.
The following tasks may be solved by means of a TCP/IP bus system:
• central control and monitoring of manufacturing facilities
• transfer of the status of machines
• management information services
• production statistics
• the transfer of large amounts of data

2-4 Rev. 00/07
2.2.1.1 General
The ISO-OSI level model is based upon a suggestion that was developed by the International
Standards Organization (ISO). It represents the first step in the direction of an international standard
for the different protocols currently in use. The model is referred to as ISO-OSI level model. OSI is
the abbreviation for Open Systems Interconnection, that is communication between open systems.
The ISO-OSI level model is not a network architecture as the services and the protocols used on the
different levels have not been defined. The model simply provides information about the task that
each level must perform.
2.2.1.2 Description of the different levels
Level 1 Physical level (bit-transfer level)
The physical level transfers data bits via a communication channel. This level is generally
responsible for the mechanical, electrical and procedural interfaces and for the physical
communication medium that is used by the physical level:
• the voltages representing a logical 0 and a logical 1.
• the duration for which the voltage must be present to represent a valid bit.
• establishes a connection and terminates it when necessary.
• pin-allocation for the respective interface.
Level 2 Data link layer
The data link layer converts raw data into a data series ready for transfer. This is where the frame
delimiters are inserted during transmission and where they are detected during reception. This is
achieved by inserting a special bit-pattern at the start and at the end of a frame. In many instances a
flow-control and error detection mechanism is integrated into the data link layer.
Level 3 Network layer
The network layer is concerned with the selection of the packet path between the source and the
destination (other networks as well). Paths may be hard-wired in the network. They may also be
dynamic, that is they may be determined on the fly for every packet in order that the load on the
network optimized. The network layer must also ensure that different packets do not interfere with
each other. This layer is responsible for administrative functions for the transferred data, that is
counting of packets, characters or bits, etc.
The network layer must have the capacity to perform these tasks so that users of heterogeneous
networks may communicate with each other.
Level 4 Transport layer
The purpose of the transport layer is to accept data from the session layer, then to divide it up into
smaller portions, transfer this data to network layer and to ensure that every item arrives properly at
the destination. The transport layer generates a unique network connection for every transport link
required by the session layer. The transport layer determines the type of service that is provided to
the session layer. It can also increase the throughput, establish multiple network connections and
assign the data to these connections.
In addition to managing the use of multiple access channels by many message streams the transport
layer must also administer connections that the network establishes and relinquishes.
