4.7. Modbus

Demo

Programs

nModbus is a C# 3.0 implementation of the Modbus protocol. It is developed and
maintained on a voluntary basis and provided free of change.

The DLL based on the official releases from

http://nmodbus.googlecode.com

was

verified and improved. Programmer can use the DLL released to develop a Modbus
application for regular Windows based PCs.

The relevant Modbus demo and SDK can be obtained from the following OMEGA
website.
