The Modbus registers are assigned within 30 seconds after the
2100 module is powered up. To conserve power for the users who
do not use Modbus communications, no Modbus registers will be
updated with sensor readings until a Modbus master communi-
cates with the 2100 module.
The register definitions for the Site Information device (Modbus
ASCII address 1) are in Table 3-1:
Table 3-1 Modbus ASCII Address 1 Register Definitions
1 Number of module (N) (1-4)

ASCII addresses 2 + (N - 1)) are in Table 3-2:
