Alicat devices are compatible with a variety of analog, serial, or industrial communication protocols for easy data collection and analysis. Options include analog (4-20 mA, 0-10 Vdc, 0-5 Vdc, or 1-5 Vdc), ASCII and Modbus RTU over RS-232, ASCII and Modbus RTU over RS-485, PROFIBUS, PROFINET, DeviceNet, EtherNet/IP, Modbus TCP/IP, and EtherCAT.
In this article, we provide answers to common questions about EtherNet/IP.

EtherNet/IP is available on most of Alicat mass flow and pressure devices:
Exceptions (incompatible with EtherNet/IP):
Yes. Gas instruments with EtherNet/IP have the full Gas Select™ list of gas calibrations and Composer™ gas mixing firmware.
EtherNet/IP uses a full duplex 10/100 Ethernet hardware layer for data rates up to 100 mbit/s.
The MOD and NET LEDs are standards in debugging EtherNet/IP networks. They are located on the case top.
The instruments are EtherNet/IP compatible and ODVA certified.
No. EtherNet/IP can only be ordered on new instruments due to the hardware and firmware requirements during installation.
DLR: Device Level Ring. Device Level Ring provides the ability to connect a series of mass flow controllers (MFCs) in a fault-tolerant ring network. It is a network topology wherein connections are made from the master to an MFC, then from MFC to MFC to MFC. DLR often reduces cabling, and adds redundancy. DLR requires a specialized ring supervisor switch, which is not provided with the instrument.
