what have you tried so far?
oh man. this sounds like my first job out of college.
i wish i could help but i never learned modbus, tho it was often talked about.
my best advice to you is to obtain a copy of the standard and read it. as torturous as that may be it is the possibly only way you're going to do it.
Maybe some carefully chosen keywords for google?
