Communications
The Brooks SLA5840 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 MAC ID switches mounted on the device.
The DeviceNet
communication link also provides access to many of the Brooks SLA 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)
