14.1 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.
Information
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.

14.2 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.
