Poll the DATA_READY coil @ address 2. If it returns true,
there is sensor data ready to view.
Read / Interpret Sensor Data
The actual data delivered by the sensor can be quickly read
by scanning the Fast Read Registers (FRR). The purpose of
these registers is to allow for efcient access to the remote
wireless device’s most current data.
Any write to the st address in the FRR will zero out the latest
measurement and time. Sensors may be set to report data in
ten second intervals out of the box, but typically should be at
10 minute intervals by default.
The following table represents the gateway’s FRR:
ADDRESS FORMULA = 41001 + (8*WDL_SLOT)
Example:
Record Name Address Record Name Address
FRR [0] 41001 FRR [99] 41793
These records consist of eight (8) registers per wireless de-
vice. The format of these records are:
Name Offset Description
TIME_H,
TIME_L
0, 1 UInt32 representation of time in seconds
DATA_0,
DATA_1,
DATA_2,
DATA_3
2, 3, 4, 5 See table below.
Battery 6 register value / 100 = x.xx Volts
RSSI 7 a negative number from -20 to -110 dBm
