20.4 Modbus Addressing Table for EXL10/XL10 PRIME Units
To access EXL10/XL10 PRIME 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, EXL10/XL10 PRIME Modbus Function
Blocks pack several EXL10/XL10 PRIME register types into each Modbus register type. Starting addresses
of each EXL10/XL10 PRIME 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.
