9424200994 Rev N 297BESTlogic™PlusBESTlogicPlus Programmable Logic is a programming method used for managing the input, output,protection, control, monitoring, and reporting capabilities of Basler Electric's BE1-11g GeneratorProtection System. Each BE1-11g has multiple, self-contained logic blocks that have all of the inputs andoutputs of its discrete component counterpart. Each independent logic block interacts with control inputsand hardware outputs based on logic variables defined with BESTlogicPlus. BESTlogicPlus equationsentered and saved in the BE1-11g system's nonvolatile memory integrate (electronically wire) theselected or enabled protection and control blocks with control inputs and hardware outputs. A group oflogic equations defining the logic of the BE1-11g is called a logic scheme.One default active logic scheme is preloaded into the BE1-11g. This scheme is configured for a typicalprotection 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 itto the BE1-11g. The default logic scheme can also be customized to suit your application.BESTlogicPlus is not used to define the operating settings (modes, pickup thresholds, and time delays) ofthe individual protection and control functions. Operating settings and logic settings are interdependentbut separately programmed functions. Changing logic settings is similar to rewiring a panel and isseparate and distinct from making the operating settings that control the pickup thresholds and timedelays of a BE1-11g. Detailed information about operating settings is provided in each chapter of thevarious protection and control functions.Overview of BESTlogic™PlusBESTlogicPlus settings are made through BESTCOMSPlus. Use the Settings Explorer to open theBESTlogicPlus Programmable Logic tree branch as shown in Figure 232.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.Figure 232.
