Reading Elements

The read element request contains the following fields:

Sensors in the Vutlan monitoring system

Sensors with a discrete output (clas = discrete)

Possible states: not connected, normal, alarm

Range of possible values: 0, 1

Parameters (attributes):

  • hwport - hardware port (connector name on the device body), read only;
  • reset - Reset the sensor memory or turn off the power:
    • 0 - immediate reset of the sensor alarm;
    • 1..86400 - reset by the timeout, after the specified time;
    • negative value (-1) - auto reset is disabled;
  • high - the upper threshold of the sensor in % (1-200 for airflow, 1-100 for other sensors);
  • low - the lower threshold of the sensor in % (1-200 for airflow, 1-100 for other sensors);
  • reverse - the flag of the sensor output inversion (0 or 1), inverts the sensor state;
  • spec - reference information for sensor adjustment (read only);

If the element does return any one of the attribute from the specified - then the value of this attribute is not determined in the process of work and its installation does not affect the operation of the element.

Elements with a discrete output can also have other attributes.

Sensors with analog output (clas = analog)

Possible states: not connected, low alarm, low warning, normal, high warning, high alarm

Parameters (attributes):

  • hwport - hardware port (connector name on the device body), read only;
  • vmax - maximum value for the measuring range, read only;
  • vmin - minimum value for the measuring range, read only;
  • low_alarm - the threshold of the "alarm, below normal" state (except for the "factor" type);
  • low_warning - threshold of "warning, below normal" status;
  • high_warning - "warning, above normal" status threshold;
  • high_alarm - threshold of "alarm, above normal" status;
  • at0 is the calibration coefficient in the formula at0*x+at75;
  • at75 is the calibration factor in the formula at0*x+at75;
  • expr - expression for calculating the output value (for conversion sensors);
  • um - the unit of measurement for the value measured by the sensor (if this attribute is missing, the units of measurement are calculated by the type attribute).
  • descr - description of the sensor;

If the element does not return any attribute from the specified - then the value of this attribute is not determined in the process of work and its installation does not affect the operation of the element.

Elements with an analog output can also have other attributes.
