CP143 H1 / TCP/IP manual Communication protocols
Rev. 00/07 2-3
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
