Three-Phase Connection (3P4W) - Siemens SENTRON 7KM PAC2200 Product Manual

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
BYTE No.
Byte 1
Byte 2
Byte 3
Byte 4
Bytes 5-6
Bytes 7-12
All measurement data that can be read out via the M-BUS are listed in the following table.
