When the transmit rate of the analog GOOSE communications is configured at a rate less than 1000 ms, only one
PMU can be used in the N60.
The measured value settings for each of the 32 analog values are shown below.

GGIO4 ANALOG 1(32) MEASURED VALUE
These settings are configured as follows.
• ANALOG IN 1 VALUE: This setting selects the FlexAnalog value to drive the instantaneous value of each GGIO4 ana-
log status value (GGIO4.MX.AnIn1.instMag.f).
• ANALOG IN 1 DB: This setting specifies the deadband for each analog value. Refer to IEC 61850-7-1 and 61850-7-3
for details. The deadband is used to determine when to update the deadbanded magnitude from the instantaneous
magnitude. The deadband is a percentage of the difference between the maximum and minimum values.
• ANALOG IN 1 MIN: This setting specifies the minimum value for each analog value. Refer to IEC 61850-7-1 and
61850-7-3 for details. This minimum value is used to determine the deadband. The deadband is used in the determina-
tion of the deadbanded magnitude from the instantaneous magnitude.
• ANALOG IN 1 MAX: This setting defines the maximum value for each analog value. Refer to IEC 61850-7-1 and
61850-7-3 for details. This maximum value is used to determine the deadband. The deadband is used in the determi-
nation of the deadbanded magnitude from the instantaneous magnitude.
Note that the
ANALOG IN 1 MIN and ANALOG IN 1 MAX settings are stored as IEEE 754 / IEC 60559 floating point
numbers. Because of the large range of these settings, not all values can be stored. Some values may be rounded
to the closest possible floating point number.
