This
vendor specific device profile
is based on the DeviceNet Fluid Flow
Controller (FFC) device profile. The
device type is 00 due to the pre-
release status of the FFC profile.
Type 00 is a Generic Device type.
A Fluid Flow Controller (FFC) is a
device that measures and controls
the flow rate of a fluid (liquid or gas).
It contains three principle compo-
nents: a flow rate sensor that can
be a virtual sensor based on other
sensors, for example pressure; a
fluid flow metering valve that can
be actuated by one of a variety of
actuator types, including, for example,
solenoid or a stepper motor; and,
a controller that closes the loop by
receiving a set point and driving the
actuator such that the fluid flow
rate is controlled to the setpoint.
This chapter contains two primary
sections. First, the device profile is
specified as it appears in general
DeviceNet specification. Second,
the vendor specific attributes,
services, behaviors, ranges and
capabilities are specified.
