Measured value expander block MVEXP

Identification

Function description
Measured value expander block

Functionality

The current and voltage measurements functions (CVMMXN, CMMXU, VMMXU
and VNMMXU), current and voltage sequence measurement functions (CMSQI
and VMSQI) and IEC 61850 generic communication I/O functions (MVGGIO) are
provided with measurement supervision functionality. All measured values can be
supervised with four settable limits: low-low limit, low limit, high limit and high-
high limit. The measure value expander block has been introduced to enable
translating the integer output signal from the measuring functions to 5 binary
signals: below low-low limit, below low limit, normal, above high-high limit or
above high limit. The output signals can be used as conditions in the configurable
logic or for alarming purpose.
