Virtual Outputs; Resetting - GE M60 Instruction Manual

INPUTS/OUTPUTS
Application example 4
A latching contact H1a is to be controlled from a single virtual output VO1. The contact is to remain closed as long as VO1
is high, and is to remain opened when VO1 is low. Program the relay as follows.
Write the following FlexLogic equation (EnerVista example shown).
Program the Latching Outputs by making the following changes in the
OUTPUTS  CONTACT OUTPUT H1a
OUTPUT H1a OPERATE
OUTPUT H1a RESET

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
