buffering capability reduces the chances of missing data state changes. Use unbuffered
reporting for local status display.

The following settings are available.
Number of Status Points
Range: 8 to 128 in steps of 8
Default: 8
This setting specifies the number of "Ind" points (single point status indications)
instantiated in the GGIO1 logical node. Changes to this setting take effect when the
Plus
D90 is restarted.
GGIO1 Indication 1, GGIO1 Indication 2,..., GGIO1 Indication 128
Range: any logic operand
Default: OFF
These settings assign logic operands to represent GGIO1 status indications.
The GGIO2 logical node provides access to the D90
virtual inputs are single-point control (binary) values that can be written by clients. They are
generally used as control inputs. GGIO2 provides access to protection virtual inputs
through the following IEC 61850 standard control model (ctlModel) services:
• Status only
• Direct control with normal security
• SBO control with normal security
Settings are used to select the control model for each point. Enable each protection virtual
input used through GGIO2, and program the corresponding SPSCO ctlModel setting to the
appropriate control configuration.
