5.5.3 FLEXLOGIC EVALUATION
Each equation is evaluated in the ascending order in which the parameters have been entered.
FlexLogic provides built-in latches that by definition have a memory action, remaining in the set state after the set
input has been asserted. These built-in latches are reset dominant, meaning that if logical "1" is applied to both set
and reset entries simultaneously, then the output of the latch is logical "0." However, they are volatile, meaning that
they reset upon removal of control power.
When making changes to FlexLogic entries in the settings, all FlexLogic equations are re-compiled whenever any
new FlexLogic entry value is entered, and as a result of the re-compile all latches are reset automatically.
5.5.4 FLEXLOGIC EQUATION EDITOR
PATH: SETTINGS  FLEXLOGIC  FLEXLOGIC EQUATION EDITOR
There are 512 FlexLogic entries available, numbered from 1 to 512, with default END entry settings. If a "Disabled" Element
is selected as a FlexLogic entry, the associated state flag will never be set to ‘1’. The ‘+/–‘ key may be used when editing
FlexLogic equations from the keypad to quickly scan through the major parameter types.
5.5.5 FLEXLOGIC TIMERS
PATH: SETTINGS  FLEXLOGIC  FLEXLOGIC TIMERS  FLEXLOGIC TIMER 1(32)
There are 32 identical FlexLogic timers available. These timers can be used as operators for FlexLogic equations.
• TIMER 1 TYPE: This setting is used to select the time measuring unit.
• TIMER 1 PICKUP DELAY: Sets the time delay to pickup. If a pickup delay is not required, set this function to "0".
• TIMER 1 DROPOUT DELAY: Sets the time delay to dropout. If a dropout delay is not required, set this function to "0".
