 VIRTUAL OUTPUT 1

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:
: "Trip"

Some events can be programmed to latch the front panel LED event indicators, target messages, and/or graphical front
panel annunciator windows. Once set, the latching mechanism holds the latched indicators, messages, or windows in the
set state after the initiating condition has cleared until a
FlexLogic latches) to the reset state where the initiating condition has cleared. The
front panel RESET button, a remote device via a communications channel, or any selected operand. The Modbus execute
function 05h with operation code 1 command is also available to perform the same function as the front panel RESET key.
