Modbus communication freeware


Thread Starter

Maurizio Scavazzon

I'm developing an application (using BCB4 Pro) to connect a PC to an electronic device using ModbusRTU Protocol. Does anybody know if exist any freeware Modbus drivers, ActiveX/OCX or
shareware that works fine. I've tried many shareware OCXs but don't work very well.
Thanks to everybody.

Ciao, Maurizio

How about the slaves ...
I need the algorithm to implement modbus comm. on 8051 microcontroller.
Could anybody give me the source code ?
