Which Types are ModBus registers RAM or Flash


I'd like to manipulate the Grid-Setpoint using an own script.
This is part of ESS-Mode2:

I already was successful setting the Grid-Setpoint using ModBus TCP (Unit-ID 242 / Register 37)
Means everything is still controlled by ESS just the Grid-Setpoint is manipulated.
So technically it works.

The only thing I was not able to find is which type of Register is it.
If it’s a RAM Register, perfect
If it’s written to the Flash a script which updates the value regularly will possibly destroy the register within days as a flash usually has about 100.000 write cycles only.

Where can I find that information? I assume there should be some list. Its not contained in the CCGX-Modbus-TCP-register-list-2.31.xlsx
