Pickup and Dropout Timers
Drop Out
Timer A drop out timer produces a true output when the elapsed time is
greater than or equal to the Dropout Time setting after a true to
false transition occurs on the Initiate input from the connected
logic. Whenever the Initiate input transitions to true, the output
transitions to false immediately. Refer to Pickup and Dropout
Timers. Double-click or right-click on the logic timer to select from
timers 1 through 16.
Pickup Timer A pickup timer produces a true output when the elapsed time is
greater than or equal to the Pickup Time setting after a false to true
transition occurs on the Initiate input from the connected logic.
Whenever the Initiate input status transitions to false, the output
transitions to FALSE immediately. Refer to Pickup and Dropout
Timers. Double-click or right-click on the logic timer to select from
timers 1 through 16.
Triggers
Falling Edge The output of a falling edge trigger pulses true when the input goes
from logic 1 to logic 0. Double-click or right-click on the logic trigger
to change the type.
Rising Edge The output of a rising edge trigger pulses true when the input goes
from logic 0 to logic 1. Double-click or right-click on the logic trigger
to change the type.
* To select the symbol type for logic gates, click the Options buttons on the BESTlogicPlus toolbar.
Programming Pickup and Dropout Timers
To program logic timer settings, use the Settings Explorer within BESTCOMSPlus to open the
BESTlogicPlus Programmable Logic/Logic Timers tree branch. Enter a Name label that you want to
appear on the timer logic block. The Time Delay value range is 0 to 250 hours in 1 hour increments, 0 to
250 minutes in 1 minute increments, or 0 to 1,800 seconds in 0.1 second increments.
Next, open the Components tab inside the BESTlogicPlus window and drag a timer onto the program
grid. Right click on the timer to select the timer you want to use that was previously set on the Logic
Timers tree branch. The Logic Timer Properties Dialog Box will appear. Select the timer you want to use.
Pickup and dropout logic timer logic blocks are shown in Figure 147. Timing accuracy is
±15 milliseconds.
