2.5.3.1 Three-phase connection (3P4W)
The measurement data is presented on three pages (Mapping 0) and on four pages
(Mapping 1). Multipage-capable masters can read out all three or four pages.
As an example, the coding of the data record with ID 13 (connection type 3P4W, Mapping 1,
i.e. version 32) is more accurately explained in the RSP_UD2 response datagram (see also
M-BUS specification):
Measured variable ID 13: L2 active energy export tariff 2
