IEC 61850 LOGICAL NODE NAME PREFIXES
The IEC 61850 logical node name prefix settings are used to create name prefixes to uniquely identify each logical node.
For example, the logical node “PTOC1” may have the name prefix “abc”. The full logical node name will then be
“abcMMXU1”. Valid characters for the logical node name prefixes are upper and lowercase letters, numbers, and the
underscore (_) character, and the first character in the prefix must be a letter. This conforms to the IEC 61850 standard.
Changes to the logical node prefixes will not take effect until the C60 is restarted.

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
•
