In this article, we provide answers to common questions about DeviceNet.

Where can I find supporting download files?

Find supporting downloads such as EDS files and the ODVA declaration of conformity here.

Which products can have DeviceNet installed?

Most Alicat flow and pressure instruments are compatible with DeviceNet.

Exceptions (incompatible with DeviceNet):

How does DeviceNet change instrument specifications?
  • Alicat part number: -DNET
  • Analog signals?: No
  • Electrical connections: Male 5-pin M12 connector for DeviceNet (top port) and male 9-pin D-sub connector for RS-232 comms (side port)
  • Additional power requirement: 170 mA
  • Available with display?: No
  • Software compatibility: LabVIEW
  • Max number of devices on network: 64
Do I still have a choice of gases and gas mixes on DeviceNet instruments?

Yes. Gas instruments with DeviceNet have the full Gas Select™ list of gas calibrations and Composer™ gas mixing firmware.

How fast are communications with a DeviceNet instrument?

The default baud rate for DeviceNet is 125 kbps. You can change the rate to 250 or 500 kbps using DeviceNet or RS-232 serial commands.

Does DeviceNet on Alicat instruments comply with the industry standard?

Yes. DeviceNet instruments are ODVA certified.

Can I update my existing instruments to have DeviceNet?

No. DeviceNet can only be ordered on new instruments due to the hardware and firmware requirements during installation.

What if I need to debug?

Your Alicat device comes with an RS-232 debug side port for diagnostics and configuration.
