3.10.1
IEC 61850-9-2 LE sampled values sending SMVSENDER
3.10.1.1
Functionality
The SMVSENDER function block is used for activating the SMV sending functionality.
It adds/removes the sampled value control block and the related data set into/from
the sending device's configuration. It has no input or output signals.
SMVSENDER can be disabled with the
Operation setting value “off”. If the
SMVSENDER is disabled from the front port WHMI, it can only be enabled from the

Operation principle
The
MINCB_OPEN
input signal is supposed to be connected through a binary input
to the NC auxiliary contact of the miniature circuit breaker protecting the VT
secondary circuit. The
MINCB_OPEN
signal sets the
FUSEF_U
output signal to block
all the voltage-related functions when MCB is in the open state.
