I have begun porting the FreeModbus Libary (http://freemodbus.berlios.de/) for the mbed.
So far modbus functions 3,4,6 & 10 for modbus RTU have been implemented.

Hi, I was looking at this code for possible use in ModbusTCP mode. When I enable the TCP mode the compiller can't find the mbtcp.h file, it's missing from the install. Has the TCP mode been tested?
Cheer!
G'day John,
I have not had a requirement for Modbus TCP as yet, so have never gotten around to trying to implement it. I'm not sure that I will be having time to revisit this project any time soon. I will be interested to hear if you are able to get TCP mode working. Good luck!
Cheers

Hi Cam,
Wondered if you'd care to share something on how do a simple "Hello World!" type of test of MODBUS RTU using your port of FreeMODBUS? Is there something on the web you can point me to help? What MODBUS testing software would you recommend? I appreciate your help.
Thanks,
Peter

Hi,
Still wondering if anyone has implemented MODBUS TCP using FreeMODBUS? I've tried but have been unsuccessful in getting the FreeMODBUS TCP code to compile with any of the mbed network libraries. Any hints really welcomed.
Thanks,
Peter
