You can use the SmartServer to integrate and manage BACnet, LON, and Modbus devices.  You can also use the SmartServer to monitor and control local discrete inputs and outputs or control relay outputs using the IOX I/O Expansion Module, and to monitor and log energy consumption using the IOX with Metering.  The BACnet, LON, and Modbus protocols all support multiple communications media.  All three support communication over Ethernet, and the SmartServer includes built-in support for communicating with BACnet, LON, and Modbus devices using an Ethernet interface.  The BACnet and Modbus protocols also support communication using RS-485.  The SmartServer IoT Pro EX model includes built-in support for communicating with Modbus RTU devices using an RS-485 interface.  The LON protocol also supports communication using free topology (FT) twisted-pair cable, high-speed twisted-pair (TP-1250) cable, and power line (PL-20) communication.  You can add expansion modules to the SmartServer to communicate with devices that do not use Ethernet or Modbus RTU.  The following table summarizes the built-in and available network and I/O interfaces for the SmartServer.  You can also create your own custom drivers for the SmartServer to support other protocols and communications media.
