Figure 5-128: Time of day timer example
The FlexLogic operand follows the state of the timers. In addition, one-second pulses are generated on the
TIME OF DAY 1 ON
and FlexLogic operands when the timers turn on and off, respectively (see the
TIME OF DAY 1 START TIME OF DAY 1 STOP
following figure). These operands can be combined in FlexLogic with the day and month FlexLogic operands and/or with
FlexElements operating on the DAYOFYEAR, DAYOFMONTH, and SECONDOFDAY FlexAnalog parameters to create virtually
any time and date condition for custom time or season-based control actions. To activate these FlexAnalog parameters,
enable at least one time of day timer.
