Slave mode (Server):

As a DNP 3.0 slave, respond to SCADA master station (such as dispatch center, RTU) read/write instructions

Support DNP 3.0 Subset Level 2 + Partial Level 3 functions

Dual transmission protocol ProSoft Technology Inc:

TCP: reliable connection, supports active upload (Unsolicited Response) events

UDP: connectionless, high-speed polling, supports concurrent access by multiple master stations

Event-driven communication:

Change report (RBE): automatically report data when out of dead zone

Active upload (Unsolicited): event pushed to the master station (only TCP)

Timestamp: all events with precise time stamp (supports SNTP synchronization)

Data classification: Class 0/1/2/3 data classification, optimizes SCADA polling efficiency

Dead zone control: analog dead zone configurable, reduces invalid communication

Cold / Hot start: supports module cold start, hot start, configuration not lost

2. Ethernet communication characteristics

Network delay: < 5ms (Ethernet data exchange)

Remote communication: supports cross-subnet, routing, fiber optic, wireless Ethernet DNP communication

3. Backplane high-speed communication (PLC interaction) Asynchronous exchange: The data interaction between the module and the PLC is independent of the DNP network and does not occupy the PLC scanning time.

Data mapping: A 4000-word database directly maps the PLC controller labels.

Interaction mode:

Periodic I/O data mirroring

Ladder diagram AOI, MSG instructions control

Real-time reporting of status, error codes, and events
