Key functions
COV and cross-subnet access
Supports COV subscriptions and BBMD cross-subnet access for change notifications and BACnet network integration.
BACnet alarms and events
Provides BACnet alarm and event functions for monitoring objects configured from the field point list.
Scripts and triggers
Use JS scripts and triggers for required control logic alongside the configured communication points.
Point-list configuration
Configure acquisition and forwarding mappings from the field point list, then upload the project for supervisory-system access.
Typical applications
Lighting-device connectivity and management; Field-meter data integration.
Model selection essentials
- Model configuration: 1 Ethernet port, 1 RS485 channel.
- This model has multiple hardware editions; confirm the processor, supply and port configuration when ordering.
Native bus ports and wiring
1 Ethernet port; COM1 is 1 native two-wire MBus port (M+/M-), and COM2 is 1 RS485 serial port (A+/B-). Connect two-wire MBus to COM1 and use a 24 V supply; four-wire MBus communication wires may connect to COM2. Do not interchange these interfaces. The ordinary serial-port count is 1; MBus is counted separately. Check each power edition for its other specifications.
