Pickup and Dropout Timers
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.
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 Figure 5-2, Pickup and Dropout Logic Timer Blocks.

Saving a BESTlogic+ File
After programming BESTlogic+ settings, click on the Save button to save the settings to memory.
Before the new BESTlogic+ settings can be uploaded to the DGC-2020, you must select Save from the
File pull-down menu located at the top of the BESTCOMSPlus main shell. This step will save both the
BESTlogic+ settings and the operating settings to a file.
The user also has the option to save the BESTlogic+ settings to a unique file that contains only
BESTlogic+ settings. Click on the Logic Library drop-down button and select Save Logic Library File. Use
normal windows techniques to browse to the folder where you want to save the file and enter a filename
to save as.
