You can build your own.
1-Modbus plus protocol is free, lots of source and code in C.
2-Use any microcontroller with SPI bus(PIC,atmel.I used motorola hc12 since easeir to implemet and debug modbus stuff.)
3-Use PIC 28J60 SPI - ethernet interface chip.(ı didnt try this part.)
How much money Schneider sells it?
Can we be rich, if you sell and if I produce

Oops, I was thinking of modbus plus as modbus tcp.
To forgive me, i searched modbus plus and foud some spec like info at below links:
www.modicon.com/techpubs/pdf/plangde.pdf
www.sksct.fi/Downloads/mb_plus.pdf
www.eecs.umich.edu/~modbus/documents/PI_MBUS_300.pdf
I could not find any source code related to modbus plus. But people say that it is pretty like modbus RTU. But I could not find any exact spec.
So change 1st step of my first post as:
1-Lots of source and code in C for modbus but modbus plus seems more specific.
Sorry..

for modbus specificaton see www.modbus.org
for modbus slave or master (simulation) softwares use www.modbustools.com
for simulation of UART (COM) in pc use Virtual Serial Port Driver sofware(search in gioogle),so you do not need to have real hardware.
for PC side you can find many applications and sources in delphi.
