Output Objects
Output objects can be logically connected to any logic block output.
Alarms
There is a variety of alarms available in the DGC-2020. Use the drag and drop method to logically
connect an alarm to a logic input. More information on alarms is available in Section 3, Functional
Description.
Pre-Alarms
There is a variety of pre-alarms available in the DGC-2020. Use the drag and drop method to logically
connect a pre-alarm to a logic input. More information on pre-alarms is available in Section 3, Functional
Description.
Senders
Sender objects can be logically connected to any logic block input.
Components
Logic Gates
Logic gates available include AND, OR, Exclusive OR, and NOT.
Latches
Latches are used to set and reset an output. Use the drag and drop method to logically connect the inputs
and output of the latch logic blocks.
Pickup and Dropout Timers
Pickup and dropout timers are used to place a time delay in the logic. For example, you may want a
500ms delay between when IN1 is sensed to when OUT4 closes. See Figure 5-2.
To program logic timer settings, use the Settings Explorer within BESTCOMSPlus to open the
BESTlogic+ 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 10 seconds in 1-second increments.
Next, open the Components tab inside the BESTlogic+ 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.
Timing accuracy is
±15 milliseconds.

Logic Comment Block
The logic comment block is used for informational purposes only. First, the Logic Comment Block is
placed on the program grid. Then, informative text is entered by double clicking on the block. See Figure
5-3.
