1-11 Specifications for GF40/GF80 Series Devices

Enhanced Diagnostics and User Interface
The mass flow controller is typically the most complex and critical
component in a gas delivery system, When dealing with toxic or reactive
gases, removing the MFC to access its functionality should be the last
resort. To address this, Brooks GF Series devices include self-diagnostics
and an independent service port for in-situ device evaluation and
troubleshooting:
• Embedded self-test routines at power-up
• Independent RS485 service port that can be accessed while the MFC is
in operation for data logging and troubleshooting
• A convenient Zero button to enable easy re-zeroing during scheduled
maintenance
Communication Interfaces
The GF40/GF80 Series supports 0-5 Vdc, 4-20 mA, DeviceNet, and
Profibus communication protocols. DeviceNet, Profibus, and RS485 are
multi-drop connections that allow a maximum of 64 devices for DeviceNet,
128 devices for Profibus and 32 devices for RS485 to be connected on the
same network. Brooks Instruments' DeviceNet profile has been certified by
the ODVA (Open DeviceNet Vendor's Association).
Brooks Instrument Profibus interface has been certified by the PNO
(Profibus User Organization).
