CP143 H1 / TCP/IP manual Communication protocols 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.
CP143 H1 / TCP/IP manual H1 protocol 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.
CP143 H1 / TCP/IP manual Communication protocols 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.
TCP/IP protocol CP143 H1 / TCP/IP manual 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.
CP143 H1 / TCP/IP manual Communication protocols Level 5 Session layer The session layer provides the links that enable users of different systems to communicate. In addition to the standard transport services the session layer also provides high-level services that may be useful for certain applications. One of these services the control of interactive functions. The session layer administers the flow of data where data can only be transferred in one direction (similar to the token-management).
CP143 H1 / TCP/IP manual TCP/IP protocol 2.2.1.3 TCP/IP in relation to the ISO-OSI level model TCP/IP is older than the ISO-OSI level model. For this reason the different layers can not be applied directly to TCP/IP. The TCP/IP network layers correspond to level 1 and 2 of the ISO-OSI model. Levels 5 and 6 of the ISO-OSI model are already integrated into the protocols of the TCP/IP application layer.
CP143 H1 / TCP/IP manual Communication protocols 2.2.2 TCP/IP principle of operation TCP and IP are only two of the many protocols required for the establishment of a complete network architecture. The application layer of the computer supplies programs like FTP and Telnet. The standard handler modules of the program define the application layer of the CP143 TCP/IP.

CP143 H1 / TCP/IP manual Network planning 3 Network planning 3.1 Ethernet network-terminology An ethernet network provides a communication link between different stations on the network. The stations on the network may consist of personal computers, industrial computers, automation equipment etc. Stations are connected to the network and located a certain minimum distance from each other. The stations on the network and the LAN cable form a network segment. (See Fig. 3-1).
Ethernet network-terminology CP143 H1 / TCP/IP manual Three types of ethernet cable exist: • Thin-ethernet-cable (also called thin ethernet cable or Cheapernet-cable). • Thick-ethernet-cable (also called thick ethernet cable or standard ethernet-cable or yellow-cable). • Twisted pair-cable (telephone cable) Thin ethernet-cable is far more economical than thick ethernet-cable. This applies to the cost of the cable, the cost of installation and any additional hardware.
CP143 H1 / TCP/IP manual Network planning 3.2 Thin-ethernet-cable networks Thin-ethernet-cable network hardware This chapter contains a description and an illustration (Fig. 3-2) of the hardware required for a thinethernet-network.

Combining thin/thick ethernet cable in networks CP143 H1 / TCP/IP manual 3.4 Combining thin/thick ethernet cable in networks It is possible to combine thin-ethernet and thick-ethernet cabling in a single network.. The lower price of the thin-ethernet cable may provide a more cost-effective solution than a system that is purely based on thick-ethernet cable. When thick-ethernet cable is used to link repeaters the distance may be substantially larger than if the link was provided by a thin-ethernet cable.
CP143 H1 / TCP/IP manual Network planning 3.4.2 Thin/thick ethernet cable combination network-layout This chapter describes a method of combining thin ethernet cable and thick ethernet cable in a single network segment. This method employs as much thin ethernet cable as possible. Fig 2-7 illustrates this technique of combining thin and thick ethernet cable. The length of a network employing a combination of thin and thick ethernet cable may be between 185 m and 500 m.

CP143 H1 / TCP/IP manual Commissioning 6.2 Start-up properties When power is turned on the CP143 H1 / TCP/IP executes the BIOS routines (hardware initialization, memory test, initialization of drivers). Once the CP-job is started the CPs program control is initiated. The frames of the DPR are only controlled from this point onwards, i.e. after the CP-job has booted up (app. 10 seconds after power on). At this time the unit waits for the synchronization from the PLC.
