DeviceNet Communications
The Brooks SLA5800 Digital Series is also available with DeviceNet
TM
communication capability. DeviceNet is an open digital protocol capable of
high speeds and easy system connectivity. Brooks Instrument has several
of its devices available on this popular networking standard, and is a
member of ODVA
TM
(Open DeviceNet Vendors Association), the governing
standard body for DeviceNet.
DeviceNet
is similar to the RS485 standard in that it is a multi-drop connection
that allows a maximum of 64 devices to be connected on the same network.
Baud rate selections for DeviceNet
products are 125K, 250K and 500K and
can be selected via a rate switch mounted on the device.
The DeviceNet
communication link also provides access to many of the
Brooks SLAMf Digital Series functions for “control and monitor” operations,
including:
• Accurate setpoint adjustment and flow output measurement (including
units of measure selection)
• PID Settings (controller only)
• Valve Override (controller only)
• Calibration Gas Select
• Soft Start Control (controller only)
