1 Introduction
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
communication from the office world up to the individual data point in the
industrial installation. 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
standardized fieldbus systems, exchanges data between the connected I/O
devices and the internal process data memory. This data can be accessed
for reading and writing 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 extensions of the functions. The development system is
economical to build up and many engineers are familiar with the
development environment. All our interfaces are open so that the
experienced user can also bring his own applications into 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.
