Modbus Addressing Table For Exl10 Units - HORNER APG EXL10 OCS User Manual

20.4 Modbus Addressing Table for EXL10 Units

To access EXL10 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 Modbus Function Blocks pack
several EXL10 register types into each Modbus register type. Starting addresses of each EXL10 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.
