BSI R11A0-XXR-CXP360-S75G
Capacitive uniaxial inclination sensor with Modbus interface
Enter direction of rotation (holding register)
The "Direction of rotation" parameter determines whether
the sensor has a positive rotation clockwise (0 = cw) or
counterclockwise (1 = ccw)
Application:
With assembly variant 1,
object and sensor turn
clockwise.
The value 0 = cw has to be
in register 135.
The sensor counts from 0°
to 359.99°
With assembly variant 2, the
object turns clockwise and
the sensor
counterclockwise.
The value 1 = ccw has to be
entered in register 135 so
that the sensor does not
count backwards (see
Section Rotation axis). The
sensor counts from 0° to
359.99°, even though it is
turning counterclockwise.

Enter indicator range (holding register)
The parameter "Indicator range" determines whether the
inclination indicator is in the range 0° to 359.99°
(parameter value = 0) or in the range of –180 to + 179.99°
(parameter value = 1).
Application:
With objects that only turn in one direction from a zero
point (e.g. solar trackers), the 0° to 359.99° indicator has
to be selected.
With objects that turn in both directions from a logical zero
point (e.g. medical tables), the –180 to + 179.99° indicator
has to be selected.

Enter offset (holding register)
The "Offset" parameter determines by how many degrees
the internal 0° position is shifted from the horizontal.
Application:
If the 0° position of the sensor is not level, but is instead
tilted by x° in relation to the machine, this tilt angle can be
declared the 0° position. In other words, the sensor starts
counting from 0° from its tilted zero setting.
In the following example, the zero position is at 45°.

Read out values (input register)
The actual values are in the input registers which are read
only (see register table).
The function code for reading applies to all input registers.

Read out inclination in the range of 360° (input register)
With the "Inclination" parameter, the inclination is read out
in the range of 0° to 359.99° with clockwise direction of
rotation (cw) in the 0 register.
