Is DNP Based on IEC 870-5? 

DNP's framing is based on (but not identical to) a framing format specified in 870-5-2. The application layer is not based on any of the 870 standards. DNP was specified soon after 870-5-2 was published, before the 870-5-4, -5 and -101 application standards were published.

 

Is DNP IEC 870-5 compliant?

No.
