Although the JACE can communicate Modbus Serial over one of its serial ports, the Modbus protocol does not allow points to be discovered like BACnet points, which requires manual configuration of each Modbus register. This can be difficult and very time consuming. By using the BASgatewayLX – Modbus to BACnet/IP gateway, with pre-defined Modbus device profiles, configuration of Modbus device registers is just as quick as configuring BACnet points. This allows for greatly reducing the time to configure Modbus devices in the field. Modbus Serial or Modbus TCP/IP points appear to the JACE's Ethernet port as BACnet/IP discoverable points.
