BESTlogicPlus Programmable Logic is a programming method used for managing the input, output,
protection, control, monitoring, and reporting capabilities of Basler Electric's DGC-2020HD Digital Genset
Controller. Each DGC-2020HD has multiple, self-contained logic blocks that have all of the inputs and
outputs of its discrete component counterpart. Each independent logic block interacts with control inputs
and hardware outputs based on logic variables defined in equation form with BESTlogicPlus.
BESTlogicPlus equations entered and saved in the DGC-2020HD system's nonvolatile memory integrate
(electronically wire) the selected or enabled protection and control blocks with control inputs and
hardware outputs. A group of logic equations defining the logic of the DGC-2020HD is called a logic
scheme.
One default active logic scheme is preloaded into the DGC-2020HD. This scheme is configured for a
typical protection and control application and virtually eliminates the need for "start-from-scratch"
programming. BESTCOMSPlus
® can be used to open a logic scheme that was previously saved as a file
and upload it to the DGC-2020HD. The default logic scheme can also be customized to suit your
application. Detailed information about logic schemes is provided later in this chapter.
BESTlogicPlus is not used to define the operating settings (modes, pickup thresholds, and time delays) of
the individual protection and control functions. Operating settings and logic settings are interdependent
but separately programmed functions. Changing logic settings is similar to rewiring a panel and is
separate and distinct from making the operating settings that control the pickup thresholds and time
delays of a DGC-2020HD. Detailed information about operating settings is provided in the
BESTCOMSPlus chapter.
Overview of BESTlogic
™Plus
BESTlogicPlus settings are made through BESTCOMSPlus. Use the Settings Explorer to open the
BESTlogicPlus Programmable Logic tree branch as shown in Figure 146.
The BESTlogicPlus Programmable Logic screen contains a logic library for opening and saving logic files,
tools for creating and editing logic documents, and protection settings.
