19.4 Modbus Addressing Table for XLE/XLT Units
To access XLE/XLT 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,
XLE/XLT Modbus Function Blocks pack several XLE/XLT register types into each Modbus
register type. Starting addresses of each XLE/XLT register type are shown in the Traditional
Modbus Reference column of the Table 19.1.
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 below, Table 19.1.
