2105 Interface Module
Section 3 Modbus Protocol and 2100 Output
3-6
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:
The register definitions for the individual modules (Modbus
ASCII addresses 2 + (N - 1)) are in Table 3-2:
