DISPLAYING
Date and time, instant data and processed data. Possibility to perform commutations and tests.

DATA PRE-PROCESSING (instantaneous measurements)
Data processing (corective tornslas, calculation algori- thms, and more).

STATISTICAL PROCESSING (recorded measures)
MicroDA acquires the instantaneous values and stores them in a temporary archive. At the end of a settable time base, stored values are processed to compute and elaborate the desired statistical data. For each measurement it is possible to define the acquisition frequency and the recording frequency. Main statistical elaborations are: instant measurements, arithmetic mean, accumulation, period, integral, vector mean, trigonometric average, minimum and maximum.

STORAGE
Initially the acquired data are saved in a temporary area (tipical- ly hourly set). Then data are permanently stored in an internal FAT memory area. Data can also be copied into an external SD memory card. Memory management can be either in linear mode (continuo-us storage up to full memory card capacity), or circulate mode data are overwritten once the memory card is full. Record track is done with a compact binary structure, to minimize the costs and time required to transfer data to a remote station.

COMMUNICATION / TRANSMISSION
• Data transmission via: internal UMTS / LTE modem (in the LTE version).
• Optional transmission via UHF radio or satellite terminal (for all versions).
• Sending data to FTP servers and alarms also via SMS.
• Communication protocols TCP-IP, FTP, MODBUS.

SELF DIAGNOSTICS
MicroDA has a set of procedures for the following controls:
• Check on the single acquisition channel;
• Check on the storage area;
• Verification of communication with the transmission system;
• Proper MPPT charger working point management.

CONFIGURABLE PARAMETERS
• Parameter name and engineering units;
• Minimum and maximum value detectable by the sensor (start of scale and full scale);
• Number of decimals after the decimal point to set the measurement;
• Corrective formula: conversion formula to obtain the value in engineering units from the incoming signal;
• Intervals for acquisition / recording and processing of data that can be generated;
• All information for sending data.

ALARMS MANAGEMENT
• Possibility to set minimum and maximum alarm thresholds (hysteresis option included to reset prior condition);
• Possibility of sending alarm SMS and changing operating frequency for data transmission.
