Resetting; Direct Inputs And Outputs - GE D30 Instruction Manual

INPUTS/OUTPUTS
The virtual inputs and outputs are digital signals associated with UR-series internal logic signals. Virtual inputs include
signals generated by the local user interface. The virtual outputs are outputs of FlexLogic™ equations used to customize
the device. Virtual outputs can also serve as virtual inputs to FlexLogic equations.
There are 96 virtual outputs that can be assigned using FlexLogic. If not assigned, the output is forced to 'OFF' (Logic 0). An
ID also can be assigned to each virtual output. Virtual outputs are resolved in each pass through the evaluation of the
FlexLogic equations. Any change of state of a virtual output can be logged as an event if programmed to do so.
For example, if Virtual Output 1 is the trip signal from FlexLogic and the trip relay is used to signal events, the settings is
programmed as follows:
VIRTUAL OUTPUT 1 ID
VIRTUAL OUTPUT 1 EVENTS

Some events can be programmed to latch the faceplate LED event indicators and the target message on the display. Once
set, the latching mechanism holds all of the latched indicators or messages in the set state after the initiating condition
