[hfebraud]

Hi everybody,

I'm looking for a solution to separate one data int64 into two data int32, in the aim to send energy from a smartlink (int64) via bacnet (int32).

In the device wich receive the two point int32 via Bacnet, i will aggregate this two points to reach the original value.

Thanks, 
Best regards
