13 Application Examples
13.1 Test of Modbus protocol and fieldbus nodes
You require a Modbus master to test the function of your fieldbus node. For this
purpose, various manufacturers offer a range of PC applications that you can, in
part, download from the Internet as free of charge demo versions.
One of the programs which is particularly suitable to test your ETHERNET
TCP/IP fieldbus node, is for instance ModScan from Win-Tech.
Additional Information
A free of charge demo version from ModScan32 and further utilities from Win-
Tech can be found in the Internet under:
http://www.win-tech.com/html/demos.htm
ModScan32 is a Windows application that works as a Modbus
master.
This program allows you to access the data points of your connected ETHERNET
TCP/IP fieldbus node and to proceed with the desired changes.

13.2 Visualization and Control using SCADA Software
This chapter is intended to give insight into how the WAGO ETHERNET fieldbus
coupler/controller can be used for process visualization and control using
standard user software.
There is a wide range of process visualization programs, called SCADA
Software, from various manufacturers.
SCADA is the abbreviation for Supervisory Control and Data Acquisition.
It is a user-orientated tool used as a production information system in the areas
of automation technology, process control and production monitoring.
The use of SCADA systems includes the areas of visualization and monitoring,
data access, trend recording, event and alarm processing, process analysis and
targeted intervention in a process (control).
The WAGO ETHERNET fieldbus node provides the required process input and
output values.
