1.1 Scope of Performance
In automation technology it is becoming obvious that Ethernet with the TCP/IP
protocol from the classical conductor field is moving continuously forward into
the fieldbus region. Although attempts are being made to lead Ethernet up to the
individual I/O modules, yet neither all the technical aspects been satisfactorily
solved nor can it be realized with a sufficient effort.
This trend is further strengthened by the requirement for unbroken communicati-
on from the office world up to the individual data point in the industrial installati-
on. Remote maintenance via the Internet is the buzzword now.
This is where our fieldbus Gateway PKV 50 comes into its own. It connects the
Internet-/Ethernet world with the harsh industrial environment of established
fieldbus technology.
It consists of a Master interface connection, which, by means of one of the stan-
dardized fieldbus systems, exchanges data between the connected I/O devices and
the internal process data memory. This data can be accessed for reading and wri-
ting by means of TCP/IP telegrams.
The Microsoft Windows CE operating system is used on the Gateway. Here,
further tasks, such as SoftPLCs, are simply added in order to incorporate extensi-
ons of the functions. The development system is economical to build up and
many engineers are familiar with the development environment. All our inter-
faces are open so that the experienced user can also bring his own applications in-
to use on the Gateway.
A further highlight is the integrated Web-Server. HTML pages can be created on
a corresponding editor and then loaded on to the Gateway. Process data can be
linked via Java Applets. All that is still needed to access the data of the Gateway
via the Internet is a Web Browser such as for example, Microsoft Explorer or
Netscape Navigator.
The configuration of the Gateways is carried out locally with our SyCon System
Configurator via the RS232C serial diagnostic interface or remotely via TCP/IP.
The PKV 50 fieldbus Gateway is now offered for the most important fieldbus
systems.
Customer-specific solutions can be implemented by us or by the customer
himself.
