Free Windows Modbus Master

I've build this page to share my learning of modbus protocol with anyone interested. You will find here some Windows 95 software to communicate with modbus slave devices. All software here are freeware and all source code it's also included, I don't know any other freeware Modbus Master , but there are many commercial products , see the link section .

My English is awful, but I hope that you understand the documentation.

The purpose of this page is not to teach modbus protocol , if you are looking for this information try these sites inside Modicon:
 - Schneider Automation site intended  to provide vendor-independent source of information for MODBUS protocol. - this is the basic document that explains modbus protocol.
