BACnet EtherNet/IP Gateway

The Siemens ProtoAir gateway provides BACnet and EtherNet/IP communications for Siemens electromagnetic, Coriolis, and clamp-on ultrasonic flow meters.

It is a cost effective interface available either as a stand-alone component for installation in a control panel or installed within a NEMA 4 enclosure with a power supply for field mounted applications.

The gateway has two (2) serial ports, one (1) Ethernet port, and a wireless access point. One serial port connects with the flow meters via an RS-485 network and communicates Modbus RTU.

The second serial port is for connection with an Automation network via BACnet MS/TP. The Ethernet port also connects with an Automation network via BACnet/IP.

The gateway also serves as an EtherNet/IP adapter.

The gateway supports a web server for setup and diagnostics. For setup, the user specifies the communication protocol and the flow meter profile.

Profiles are pre-configured and map the instrument Modbus data to BACnet or EtherNet/IP communication objects.

The profiles provide process variable, alarm, and instrument diagnostic data.

The web server is accessible via the Ethernet port or via the wireless access point. The gateway supports network security.
