Explanation:
● Operating time counter: the working time of the device is stored in non volatile memory since first power on or since last reset
command (see par 4.5); this increasing counter has resolution 0,1h (6 min)
● Temperature: it's the temperature measured internally by electronics, with 0,1°C resolution; this value is volatile
● Temperature Max: it's the maximum temperature measured internally by electronics, with 0,1°C resolution, stored in non vol-
atile memory, since first power on or since last reset command (see par 4.5)
● Nominal Span: it's the full range stroke of the device as defined in the ordering code, with 1um resolution
● Serial Number: it's the Serial Number as reported on device nameplate
● Calibration Date: it reports the date of calibration of device in the coding YYYYMMDD
● SensorSWVersion: SW version of the processor managing the measure

Explanation:
● ResetUserStatisticsData: through this command the user can request the reset of following statistics data:
- OperatingTimeCounter
- TemperatureMax
● StoreStatisticsData: through this command the user can force an immediate storage of statistics parameters (OperatingTime-
Counter and TemperatureMax), otherwise the auto saving happens every 6 min
In case of Diagnostics events the WPA-F / WRA-F communicates through Profinet alarm messages the following:

Number of cursors Error
5
Temperature Error
19
Internal Communication Error
Explanation:
● Parameterization Error: the device received an uncorrect parameterization
● Supply Voltage Error: the error rises according to the configuration of parameter "Voltage Supply Alarm"
● Number of cursors Error: the error rises according to the configuration of parameter "Number of Cursors Alarm"
● Temperature Error: the error rises if Electronics temperature overtakes the working temperature limit
● Internal Communication Error: the error rises if a failure in internal communication between processors happens
