= Virt Op 4
END
In this expression, the virtual output 4 input to the four-input OR is listed before it is created. This is typical of a form of
feedback, in this case, used to create a seal-in effect with the latch, and is correct.
8.
Always test the logic after it is loaded into the relay, in the same way as has been used in the past. Testing can be
simplified by placing an "END" operator within the overall set of FlexLogic equations. The equations are evaluated up
to the first "END" operator.
The "On" and "Off" operands can be placed in an equation to establish a known set of conditions for test purposes, and
the "INSERT" and "DELETE" commands can be used to modify equations.

There are 1,024 FlexLogic entries available, numbered from 1 to 1024, with default END entry settings. If a "Disabled"
element is selected as a FlexLogic entry, the associated state flag is never set to '1'. Press the +/– key when editing
FlexLogic equations to quickly scan through the major parameter types.

There are 32 identical FlexLogic timers available. These timers are used as operators for FlexLogic equations.
— Selects the time measurement unit.
TIMER 1 TYPE
— Sets the time delay to pickup. If a pickup delay is not required, set this function to "0."
TIMER 1 PICKUP DELAY
— Sets the time delay to dropout. If a dropout delay is not required, set this function to "0."
