20.5 Modbus Addressing Table
To access XL+ registers, a Modbus Master must be configured with the appropriate register
type and offset. This is usually accomplished with one of two methods:
Method 1: The first method uses Traditional Modbus References, in which the high digit
represents the register type and the lower digits represent the register offset (starting with
Register 1 for each type). Since only four register types can be represented in this manner,
XL+ Modbus Function Blocks pack several XL+ register types into each Modbus register type.
Starting addresses of each XL+ register type are shown in the Traditional Modbus Reference
column of the Table 20.1.
Method 2: The second method requires the Modbus Master to be configured with a specific
Modbus Command and Modbus Offset. The supported Modbus commands and the associated
offsets are also illustrated in Table 20.1.
