Status registers (6601-6603) contain a bit-packed representation defining the devices that are operational in the wireless
system.
If the device's status register (input 8) contains a 128, a one (1) is written to the Discrete Status Register area, indicating the
device is active in the wireless system. If the device's I/O 8 contains any number other than a 128, a zero (0) is written,
indicating the device is not active within the wireless network. In this way, an analog value representing the device's status
within the wireless network is converted to a discrete value.
Input registers from all devices use Modbus registers 6611 through 6683 to organize the least significant bit into a
sequential array of registers. The first register contains the least significant bit from the input values for the Gateway through
Node 15. The second register contains the input values for Node 16 through Node 31, and the third register contains the
input values for Nodes 32 through 47.
For discrete inputs, only the least significant bit is used. For analog inputs, the least significant bit indicates if the analog
value is above or below the selected threshold value (when using the threshold parameter). For example, a least significant
bit of one (1) indicates the analog value is above the selected threshold value. A least significant bit of zero (0) indicates the
analog value is below the threshold value.
Output registers from all devices use Modbus registers 6691 through 6753 to organize the least significant bit into a
sequential array of registers. Output 8 (I/O point 16) cannot be written using the discrete format.

2.2.3 Analog 16-Bit Registers (Registers 6801 through 9098)

The most efficient way to read (or write) analog data from a Gateway is by using these 16-bit analog registers. Most
networks consist of similar Nodes reporting data using the same I/O registers for each Node. For this reason, the analog
data is arranged by I/O point using Modbus registers 6801 through 9098. For example, Input 1 for Gateway and all Nodes is
stored in the first 48 contiguous blocks of 16-bit analog registers, beginning with register 6801.
