Each relay can be selected to become either energized or de-energized when operated,
and to operate as latched, self-resetting or pulsed.
EVENTS
Range: Enabled, Disabled

The selection of the Enabled setting enables the events of the function.
TARGETS
Range: Disabled, Self-reset, Latched
Default: Self-reset
This setting is used to define the operation of an element target message. When set to
"Disabled," no target message is issued upon operation of the element. When set to
"Self-Reset," the target message and its LED indication follow the operate state of the
element, and self-reset once the operate element condition clears. When set to
"Latched," the target message will remain visible after the element output returns to
logic 0 until a RESET command is received by the relay.
