Dear friend:

I invite you to visit modbus-ida organization WEB site (http://www.modbus-ida.org/). Modbus is an open source protocol and there you will find its full description and programming examples in different languages.

 

Check http://www.nmodbus.com. Nmodbus is a C# implementation of the modbus protocol.

 

Hi, I wrote a Modbus application in VB.Net 2005 that supports commands 01, 02 03, 04, 06, 15
It will show you how to build xmt strings and parse rcv strings; and it has a CRC generator.
Email me and I'll send you a copy.
