DeviceNet Communications
The Brooks SLAMf Digital Series is also available with DeviceNet
TM
communi-
cation 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 rate switches 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)
For external connection see DeviceNet connections on Figure 1-6.
Note: Aux Input is used for Remote Trans-
ducer Pressure Controllers only.
