INTRODUCTION
BESTlogic+ Programmable Logic is a programming method used for managing the input, output,
protection, control, monitoring, and reporting capabilities of Basler Electric's DGC-2020 Digital Genset
Controller. Each DGC-2020 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 BESTlogic+. BESTlogic+
equations entered and saved in the DGC-2020 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-2020 is called a logic scheme.
One default active logic scheme is pre-loaded into the DGC-2020. 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-2020. The default logic scheme can also be customized to suit your application. Detailed
information about logic schemes is provided later in this section.
BESTlogic+ 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-2020. Detailed information about operating settings is provided in Section 3, Functional
Description.
OVERVIEW OF BESTlogic+
BESTlogic+ settings are made through BESTCOMSPlus. Use the Settings Explorer to open the
BESTlogic+ Programmable Logic tree branch as shown in Figure 5-1.
The BESTlogic+ Programmable Logic screen contains a Logic Library for opening and saving logic
scheme files, tools for printing and editing, and three groups of objects used for programming.
