7 System Overview
A powerful software package for remote control is available for the
automation platform IndraWorks. The NetSupport client software is
therefore installed on the control unit. When connecting via TCP/IP, the
service PC can access the control unit either using the NetSupport control
software or a WEB browser (as of IE4.0).
The WEB browser thereby communicates via an ActiveX Control with the
WEB server integrated on the control system. An additional installation on
the service PC is not required.
7.1 Network Topologies
A remote session can be run using a large variety of network topologies,
such as remote data communication/Internet or within various LAN
topologies. Several possible configurations are listed in the following to
provide you with a better overview of these various possibilities.
Direct Connection via Remote Data Communication/Internet
The simplest network structure possible for connecting a remote ession
between a control unit and a service PC is a remote data communication
connection.
Under Windows the control system must be configured as a RAS server
and the service PC as a RAS client. The actual connection is then
established by the modem of the control system via the telephone line to
the modem of the service PC.
If the control system and the service PC are connected to the Internet,
then remote diagnostics can also be carried out directly via the Internet. In
this operating mode, the NetSupport client software must be accordingly
configured on the control system in order to prevent unauthorized access
by users on the Internet.

Note: I-Remote via a direct telephone connection is preferable to an
Internet connection for reasons of security.
