The Schneider Electric LSS100300 is a dedicated BACnet/IP Gateway designed specifically for integrating KNX building automation systems with Building Management Systems (BMS). Unlike the LSS100100 and LSS100200 logic controllers, the LSS100300 serves as a protocol converter, enabling bidirectional communication between KNX installations and BACnet-based BMS platforms like EcoStruxure Building Operation.

Key Features
Bidirectional Protocol Gateway
KNX to BACnet/IP conversion: Seamlessly integrates KNX devices into BACnet-based BMS
Bidirectional communication: Read and write operations between both protocols
Multi-device support: Connects entire KNX installations to BMS platforms
BMS Integration
EcoStruxure Building Operation: Native compatibility with Schneider Electric BMS
Third-party BMS support: Works with any BACnet/IP-compliant building management system
Simplified commissioning: Reduces integration complexity for mixed-protocol environments
Core Functions
Protocol translation: Automatic conversion of KNX data points to BACnet objects
Data mapping: Flexible configuration of KNX group addresses to BACnet properties
Real-time monitoring: Live status updates between KNX field devices and BMS
Control operations: BMS can send commands to KNX actuators through the gateway
Network Services
KNX IP routing: Functions as KNXnet/IP router
BACnet B-BC profile: BACnet Building Controller certification
Ethernet connectivity: Standard RJ45 connection to IP networks
