EM4300 Meter Modbus Registers and data types

Have reviewed the User Manual 7EN02-0356-02 06/2016.  It is likely that we will have customers with application for this device.   Confused by three things?

1.  Int24

2.  Int48

3. Clusters and Attributes

We are very familiar with Modbus registers and BACnet objects.  In these worlds data is typically in groups of 16 bits that are either signed (+/-) or unsigned.  Larger number are often in an IEEE or Mod10k format.

Can anyone tell what Int24 or Int48 represent?

In Modbus data is often stored in 4x register.  BACnet has Objects.  How do we use Clusters and Attributes?
