Eaton PT 10 Instruction Manual page 31

Each data object occupies two registers (four bytes) in length, except for certain energy objects. These energy objects occupy
four registers. Since these objects have the capability to change in real time, a complete data object must be obtained in a
single transaction to avoid data tearing. Attempting to access a partial data object will result in an exception code 84. (See
Section A.3.11)
