8 Application Examples

8.1 Test of MODBUS Protocol and Fieldbus Nodes

A MODBUS master is required to test for proper functioning of fieldbus
nodes. Various PC applications from different manufacturers are offered for
this purpose, and you can download some of these from the internet as free
demo versions.
A program that is very suitable for testing your ETHERNET TCP/IP fieldbus
nodes, e.g. ModScan by Win-Tech.
Additional Information
A free demo version of ModScan32 and other utilities from Win-Tech area
available online:
http://www.win-tech.com/html/demos.htm.
ModScan32 is a Windows application that functions as a MODBUS master.
Use this program to access data points for linked ETHERNET TCP/IP field-
bus nodes and make any required changes.

8.2 Visualization and Control Using SCADA Software

This section can and should provide only limited insight on using the WAGO
Fieldbus Controller with standard application software for process visualiza-
tion and control.
There is a wide range of process visualization programs (SCADA software)
available from a number of manufacturers.
Additional information
To view a wide selection of SCADA products, go to:

SCADA is the acronym for "Supervisory Control and Data Acquisition".
This is a user-oriented tool that is used in close touch with production as a
production data system for the sectors automation technology, process control
and production monitoring.
