6.3 Metering values, addressing und data traffic
Basic type 3
Basic type 3 was implemented according to the LVSG profile of the PROFINET user
organization (PNO) and comprises fourteen data blocks containing metering values. These
are preassigned such that unmodified use is only meaningful with a 3WA circuit breaker with
metering function.
The predefined data blocks cannot be modified.

Basic type 4
Basic type 4 comprises four data blocks. These are preassigned such that they are primarily
suitable for use with a 3WA circuit breaker without metering function. The most important
currents of the phases are transferred.
The predefined data blocks cannot be modified.
