Is there any windows based software that can be used as a Test tool for checking MODBUS - RTU Slaves ?

I know a few like Modscan32 , ModbusPoll etc. But none of these can handle non standard function codes . Some vendors like Bonfiglioli develop their VFDs with such function codes : 100 for 32Bit write and 101 for 32Bit read.

I guess you have to ask these vendors for such a tool. Simply because that isn't Modbus anymore.
