Virtual outputs are FlexLogic™ equations whose output (or result) can be used as inputs to
other equations. The 745 has five (5) virtual outputs. One application of these outputs may
be to contain a block of logic that is repeated for more than one output.
This section contains the FlexLogic™ equations to configure virtual outputs 1 to 5. The
setpoints describe the parameters of the FlexLogic™ equation for virtual output 1(5) as
described in Introduction to FlexLogic™ on page 5–99.

Protection and monitoring elements already have their own programmable delay timers,
where they are required. For additional flexibility, ten (10) independent timers are available
for implementing custom schemes where timers are not available. For example, a pickup
delay timer may be required on a logic input; or, a single delay timer may be required on
the output of a block of logic.
• TIMER 1(10) START: Select the FlexLogic™ entry which, when operated or asserted, will
start timer 1(10).
• TIMER 1(10) PICKUP DELAY: Enter the delay time during which the start condition for
timer 1(10) must remain operated or asserted, before the timer will operate.
• TIMER 1(10) DROPOUT DELAY: Enter the delay time after which the start condition for
timer 1(10) must remain not operated or not asserted, before the timer will stop
operating.
