The newly
developed sensor Profibus module model 9221 is
predestined for integration of various analog sensor
output signals into complex, networked and peripheral
automation structures. This module finds its fields of
application in the industrial automation technology as
well as the test stand technology based on its secure
and reliable transfer mode, the fast transfer speed
and its simple construction.
The inputs (e.g. PLC signal gage) and outputs in
addition to the external control allow a zeroing by
trigger via proximity switch or fast alerting on
passing of setpoint values.
Industrial type connection and mounting techniques
enable the user the adaption and integration in the
existing mechanical and electrical environment.
The excellent quality of measurement together with the
high grade capture of mean values also enable the
application in research and development.
The use of standardized Profibus protocols makes the
connection an easy task for the programmer.

| Description |
 |
The
universal sensor Profibus module is well-suited for
measuring mechanical values such as e.g. force, torque,
pressure, acceleration, displacement and angle. Strain
gage, potentiometric and standard signals may be
captured and processed without problems. A powerful 16
bit A/D converter ensures a precise and fast
processing of analog sensor signals.
The module itself features a stable and precise sensor
supply voltage. The calibration and configuration data
are memorized on an EEPROM, protected against zero
voltage.
The user friendly configuration software makes a
simple conditioning of input signals and the setup of
parameters on the module in regards to the PLC and
Profibus parameters possible. The version DPV1 enables
the parameterization and backup function via Profibus.
Functions such as the arithmetrical calculation of
mean values, input signal filtering, zero adjustment,
min/max-memory and setpoint values can be realized
with a speed up to 12 Mbaud via Profibus.
Two potential-free and freely configurable digital
inputs are available for the external PLC-control (e.g.
erase min/maxmemory, tare function). Two digital
outputs can be defined as local setpoint value
switches for alerting functions, for example.
The bus-sided control of the sensor lines on fractures
or shortcircuits and the galvanic separation between
the Profibus-ASIC and the Profibus connector belong to
the standard features.
The visualization of operating conditions such as bus
connection, sensor-sided errors or active state of
module are realized by three LEDs.
The DIN rail mounting allows quick and simple mounting
in switchboard cabinets.
