This network system collects data from various building automation (BA) systems, including HVAC, lighting, smoke and fire detection, etc. It utilizes the industrial communication companion chip RZ/N2L MPU and various devices to support communication protocols like Ethernet-based 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, BACnet
    • Industrial Ethernet protocols such as Modbus TCP, EtherNet/IP, EtherCAT, etc.
    • RS-485 transceiver with BA serial communication such as BACnet MS/TP, Modbus RTU, etc.
    • NB-PLC modem that supports PLC communication in the BA system.
  • MPU has a built-in TSN-compliant 3-port Gigabit Ethernet switch and can support Time-Sensitive Networking (TSN) compatible devices.
  • MPU HOST I/F allows for easy and high-speed connectivity to the existing system.




  • Building automation (BA) systems
  • HVAC systems (like unitary controllers)
  • Network gateway
