Please:
I need urgent help!
My application use DNP 3.0 for RTU communications
But i need URGENTLY the CRC calculation algorithm
Implementations using the polynomial
X16 + X13 + X12 + X11 + X10 + X8 + X6 + X5 + X2 + 1
don't work!!
what is the mistery for this CRC calculation?
Thanks

 

Regarding X16 + X13 + X12 + X11 + X10 + X8 + X6 + X5 + X2 + 1, what software environment do you have? Is this a 32-bit Windows program or a microcontroller program. The platform makes a difference as to how to proceed.

Try http://www.dnp.org/ and use the search box (at the top of the page) to search for crc. They have a pdf document with example calculations in C.
