generally be used for SOE logs since the buffering capability reduces the chances of
missing data state changes. Unbuffered reporting should generally be used 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) that are
instantiated in the GGIO1 logical node. Changes to this setting will not take effect until

the D90 is restarted.
GGIO1 Indication 1, GGIO1 Indication 2,..., GGIO1 Indication 128
Range: any logic operand
Default: OFF
These settings assign operands to represent GGIO1 status indications.
The GGIO2 logical node is available to provide access to the D90
inputs are single-point control (binary) values that can be written by clients. They are
generally used as control inputs. GGIO2 provides access to virtual inputs through the
IEC 61850 standard control model (ctlModel) services:
• Status only
• Direct control with normal security
• SBO control with normal security
Configuration settings are available to select the control model for each point. Each virtual
input used through GGIO2 should be enabled and the corresponding SPSCO ctlModel
setting programmed to the appropriate control configuration.
