DIRECT INPUT 1-1(8) DEFAULT — Selects the logic state of this particular bit used for this point if the local relay has just
completed startup or the local communications channel is declared to have failed. Setting
DIRECT INPUT 1-1(8) DEFAULT to
“On” means that the corresponding local FlexLogic operand (DIRECT I/P 1-1(8)) has logic state “1” on relay startup or during
communications channel failure. When the channel is restored, the operand logic state reflects the actual state of the
corresponding remote direct output.
5.9.5.3 Direct outputs
SETTINGS  INPUTS/OUTPUTS  DIRECT  DIRECT OUTPUTS
The relay provides eight direct outputs that are conveyed on communications channel 1 (numbered 1-1 through 1-8) and
eight direct outputs that are conveyed on communications channel 2 (numbered 2-1 through 2-8). Each digital point in the
message must be programmed to carry the state of a specific FlexLogic operand. The settings are used to select the
operand that represents a specific function (as selected by the user) to be transmitted.
Direct outputs 2-1 to 2-8 are functional in three-terminal systems.
