DNP3 Driver - A Python implementation for DNP3 protocol communication over IP.

This driver implements the DNP3 (Distributed Network Protocol 3) protocol

for SCADA communications, supporting master station functionality to communicate

with DNP3 outstations over TCP/IP.

Protocol Structure:

- Data Link Layer: Frame format with CRC-16 error checking

- Transport Layer: Message segmentation and reassembly

- Application Layer: Function codes and data object handling

Supported Features:

- Binary Inputs (Group 1, 2)

- Binary Outputs (Group 10, 12)

- Analog Inputs (Group 30, 32)

- Analog Outputs (Group 40, 41)

- Counters (Group 20, 22)

- Class data polling (Class 0, 1, 2, 3)

- Select-Before-Operate (SBO) control

- Direct Operate control

- Time synchronization

- Unsolicited responses

Public API (import from dnp3py):

DNP3Master, DNP3Config, DNP3Error, DNP3CommunicationError,

DNP3TimeoutError, DNP3ProtocolError, DNP3CRCError, __version__
