Answer :
This is based on the application level of your application.
If you have an application defined with an M580 of 2.70 and lower, you will see the T_M_ECPU_HSBY.
If you have an application defined with an M580 of 2.80 and higher, you will see the T_M_ECPU_HSBY_EXT.
In the PDF attached the differences between the 2 types have been identified.
