6.4. User data

Contrary to diagnostic data, user data refer directly to the process being controlled or monitored.

Regarding the inclination sensor, user data are both the inclination data of the two axes that are

transmitted via Profibus to the control (master), and second maybe a preset or offset value.

Significance is as follows:

Preset: The inclination sensor can be preset to a certain angular value.

Offset: A predefined angular value is added to the measured angular value.

User data are exchanged in Data_Exchange Mode, the general conditions for the exchange (for example

resolution of the inclination sensor) are to be previously defined in the configuration.

By data exchange the slave informs the master in case a diagnostic incident occurred, the master will then

request the actual diagnostic and status information.

For setting a preset, the master transmits to the slave the preset value (within the range from –30000 ….

+30000 to –30 ... +30, depending on the selected solution). See also „preset function“.

In mode "Data Exchange" the DUO-LED in the bus cover is green continuous.

6.5. Inclination angle readout

Inclination angle readout is by two dual words each, since for each axis there are 4 bytes each to read-in.

Taking for granted a previously parameterized resolution of 0.1° (not shown in the figure) the inclination

angle of the X-axis in the above figure is: 39h= 57dez = 5.7°

Analogue calculation relating to the Y-axis = B7h = 183dez = 18.3°

The inclination angle of the 360° inclinometer sensor release as x-axis. The Y-axis cannot transmit any

value and therefore the Y-axis is always zero.
