MMXU DEADBANDS
The MMXU deadband settings represent the deadband values used to determine when the update the MMXU “mag” and
“cVal” values from the associated “instmag” and “instcVal” values. The “mag” and “cVal” values are used for the IEC 61850
buffered and unbuffered reports. These settings correspond to the associated “db” data items in the CF functional con-
straint of the MMXU logical node, as per the IEC 61850 standard. According to IEC 61850-7-3, the db value “shall repre-
sent the percentage of difference between the maximum and minimum in units of 0.001%”. Thus, it is important to know the
maximum value for each MMXU measured quantity, since this represents the 100.00% value for the deadband.
The minimum value for all quantities is 0; the maximum values are as follows:
• phase current: 46
×
phase CT primary setting
• neutral current: 46
×
ground CT primary setting
• voltage: 275
×
VT ratio setting
• power (real, reactive, and apparent): 46

GGIO1 STATUS CONFIGURATION
The
NUMBER OF STATUS POINTS IN GGIO1
setting specifies the number of “Ind” (single point status indications) that are
instantiated in the GGIO1 logical node. Changes to the
NUMBER OF STATUS POINTS IN GGIO1
setting will not take effect until
the C60 is restarted.

The GGIO2 control configuration settings are used to set the control model for each input. The available choices are “0”
(status only), “1” (direct control), and “2” (SBO with normal security). The GGIO2 control points are used to control the C60
virtual inputs.
