Control.com - Nerds in Control

Does anyone know where I can find the source for modbus_tcp written by Phil Costigan? specifically, modbus_tcp.c and modbus_tcp.h. I have been unable to contact Mr. Costigan-- it appears that the links to his website and email that I have come across are out of date.

I am trying to interface a PC-104 linux computer with some sixnet ethertrak control modules that speak modbus/tcp.

Thanks!

I'm not sure if it's the one you're thinking of, but the MatPLC can handle Modbus, and parts of our Modbus module were written by Phil Costigan...
http://mat.sourceforge.net
http://mat.sourceforge.net/manual/io/modbus.html

As you can see from the manual, the MatPLC is really only ready to be used as a Modbus master (not a slave); however, this is probably the side you need...

Cool! That sounds like an exact fit for MatPLC... Any more details you'd be willing to share with us? (Either here or on the mat-devel mailing list?)
