Multi-Protocol Network System for Building Automation

Network systems for building automation are essential for managing, controlling, and monitoring various functions within a building, such as heating, ventilation, and air conditioning (HVAC), lighting, security systems, and energy management.

This network system collects data from various building automation (BA) systems, including HVAC, lighting, and smoke and fire detection. It utilizes the industrial communication MPU and various devices to support communication protocols like Ethernet-based OPC Unified Architecture (OPC UA) and BACnet. Additionally, it supports communications via RS-485 and power line communication (PLC), commonly used in BA networks.

System Benefits:

• Supports gateway systems covering various network hierarchies:
  • BA Ethernet functions such as OPC UA and BACnet.
  • Industrial Ethernet protocols such as Modbus TCP, Ethernet/IP™, and EtherCAT^®.
  • RS-485 transceiver with BA serial communication such as BACnet MS/TP and Modbus RTU.
  • Narrowband PLC (NB-PLC) modem supports PLC communication in the BA system.
• The MPU has a built-in TSN-compliant 3-port Gigabit Ethernet switch and can support Time-Sensitive Networking (TSN) compatible devices for real-time data transmission and network efficiency.
• MPU HOST I/F allows for easy and high-speed connectivity to the existing system.
