Secondary Device Functions (continued)
6.12 Inclination and Installation Aid
6.12.1 Description
This feature offers two functions:
– Inclination detection
– Installation and alignment aid
The inclination aid detects a deviation in the inclination
compared to a reference position. The reference position
can be freely selected and taught in.
The internal position sensor follows the vertical earth axis.
Angular deviations to this axis can be recognized, parallel
shifts to the axis or rotation around this axis cannot (see
Fig. 6-9).
Measurement data for inclination detection:
– Measurement range: 0…180°
– Resolution: 1°
– Accuracy: +/−1°
– Measurement period: 1000 ms (data refresh rate =
1 second)
With the inclination detection it can be recognized whether
the device has changed its original installation position and
therefore a possible misalignment and resulting
malfunctions can be detected at an early stage.
The configuration can be performed via ISDU parameters
(see chapter
ISDU
on page 80).
Using the feature
1. Switch on, establish IO-Link communication.
2. Send system command 0xC0 .
⇒
The inclination measurement data is available via
ISDU (e.g., 0x2154) or via the process data.
Recognizable adjustments
Reference
Only the inclination is detectable (as angle
difference to reference).
Non-recognizable adjustments
Reference
Vertical and horizontal
shifts
Rotation
Fig. 6-9: Recognizable and non-recognizable adjustments: The
adjustment can be a rotation, inclination or movement.
With the function, the inclination (green arrow) can be
detected, but shifts or rotation (red arrows) cannot.
6.12.2 Mathematics/Algorithm
The inclination deviation is compared neither directly with
the horizontal plane nor with the vertical gravitational field,
but rather with the taught-in orientation.
In summary:
– Inclination deviation = absolute value of (taught-in
reference orientation – actual orientation)
– Values: 0…180
– Unit: Degrees (°)
