11.2 ETHERNET RJ45 PORT CONNECTION (Modbus TCP - BACnet IP - Web Server)
The SySmart
3
microprocessors can be connected to a supervision and/or BMS (Building Management System) system,
which adopts the Modbus TCP (Standard) or BACnet IP (Accessory) protocol through a dedicated RJ45 serial board.
Through the RJ45 serial board it is also possible to view supervision Web pages through the Web Server function (Accesso-
ry).
To make the connection to the Ethernet network, simply connect the SySmart
3
microprocessors through the RJ45 port on
the board:
