Introduction
Table 1 – feature list describing those available in each version
1.4.2 Telemetry and SDI-12 Diagnostics
Monitoring operation of the communications modules and SDI-12 bus is possible from the iLink software. The
Architecture allow for remote monitoring, monitoring over open channels (Radio) even monitoring of the operation of
the channel being used. The information obtained is time stamped real time log with three levels (information,
warning/error), which this can be filtered and captured for later analysis.
1.4.3 Power Management
The iRIS supports power management in two main ways. These can be used to save power for sites that have a small
power budget:
§
LED activity – The status LED can be set to turn off after a user defined timeout.
§
Checking SMS on Cellular module – the checking for incoming SMS can be disabled to save power.
1.4.4 Data Logging
The iRIS supports the logging of data from up to twenty virtual sensors. Each of the virtual sensors can obtain
information from one of the following data sources:
§
Analogue input on AIN1 – AIN2
§
Pulse counter attached to DI1, DI2 or DIO
§
Simulated pulse counter enabled by DI1, DI2 or DIO
§
Frequency counter attached to DI1, DI2 or DIO
§
Up/down counter attached to DI1, DI2 or DIO simultaneously
§
SDI-12 instrument channel 1
§
Change of status on charger input (dc supply)
§
Battery voltage
§
Supply (charger) voltage
§
Logger temperature
§
Received Signal Strength Indication (RSSI)
§
Change Of State on digital I/O channels DI1, DI2 or DIO
§
Serial instrument (using the Modbus protocol) (Only available on iRIS Under Cover Pro Version)
Each sensor can be set up to scale the raw data source into engineering units through the application of a multiplier and
offset (slope and constant). The scaled value can be logged to non-volatile memory at rates between once per minute to
once per hour or immediately in true event mode for pulse inputs.
It is also possible to configure a sensor to also log associated values such as minimum, maximum, standard deviation (for
all source types) or a calculated flow rate or volume (pulse type sources only). See the next section for further details on
configuring these extended logging features as part of the Sensor Cfg menus.
