MODBUS Data Map and Information
Interpretation of Moxa Switches
The data map addresses of Moxa switches shown in the following table start from MODBUS address
30001 for Function Code 4. For example, the address offset 0x0000 (hex) equals MODBUS address 30001,
and the address offset 0x0010 (hex) equals MODBUS address 30017. Note that all the information read
from Moxa switches are in hex mode. To interpret the information, refer to the ASCII table for the
translation (e.g. 0x4D = ‘M’, 0x6F = ‘o’).
