Configuration / Configurazione

To configure this signal converter it is necessary to use a RF Programmer (2000.35.012) and the configuration software RF Programmer, available on download area www.pixsys.net. After connecting the RF Programmer via USB and activating the software, it is possible in "EDIT" mode to configure the device selecting type of sensor, measuring range, output for error signal and sampling frequency for the registration. The keys "WRITE” and “READ” allow to write and read data on the devices quickly and easily.

On the lower side of the display a list of all programmed devices is showed; it can be printed to confirm that the programming has been completed successfully.

La configurazione di questo convertitore di segnale richiede l'utilizzo di un base programmatore RF Programmer (2000.35.012) e del software di configurazione RF Programmer scaricabile dall'area download nel sito www.pixsys.net. Dopo aver connesso tramite porta USB I'RF Programmer e attivato il software è possibile con la modalità "EDIT" parametrizzare il dispositivo selezionando il tipo di sensore, range di misura, uscita per segnalazione errore e la frequenza di campionamento per la registrazione. Con i tasti "WRITE" e "READ" è possibile scrivere e leggere i vari dispositivi velocemente e in modo agevole.

Nella parte bassa dello schermo appare la lista riassuntiva dei dispositivi programmati, che può essere stampata per certificare la buona riuscita delle operazioni.

Data Logger

This signal converter is provided with a datalogging function for the input signal. Fixing the sampling time (1..3600 seconds) each time the loop 4..20mA powers the device up, this will store the input value into a non-volatile memory. Through the RF Programmer it is possible to download/display/print all data.

Questo convertitore di segnale è provvisto di una capacità di storicizzazione del segnale in ingresso. Fissando il tempo di campionamento (impostabile tra 1 e 3600 sec.) ogni volta che il loop 4..20mA alimenterà il dipositivo questo archivia il valore in ingresso su una memoria non volatile. Tramite I'RF Programmer è possibile scaricare tutti i dati e presentarli a video o stamparli.

A visual representation of logged data shows a trend of temperature over time, with a sampling point indicated.
