5.2 PRODUCT SETUP
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 B90
virtual inputs.
The GGIO4 analog configuration points are shown below:

changed, the B90 must be rebooted in order to allow the GGIO4 logical node to be re-instantiated and contain the newly
configured number of analog points.
The measured value settings for each of the 32 analog values are shown below.

 GGIO4 ANALOG
 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.
