CHAPTER 4: INTERFACES FLEXLOGIC DESIGN USING ENGINEERB90 LOW IMPEDANCE BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL 4-614Figure 4-63: Logic diagram4.4 FlexLogic design using EngineerParts of EnerVista Viewpoint Engineer software are integrated in the EnerVista UR Setup software. Engineer can be used tocreate and modify FlexLogic that is used by a device, such as to monitor output, monitor triggers, and create self-tests.Features include• Automatically displays existing FlexLogic• Drag-and-drop interface• Open multiple tabs and edit simultaneously• Display symbols in IEC, ISO, or UR formats• Export a diagram as BMP file or copy it to the clipboard for import into other applications• Scale and print files in various paper sizes• Works with all UR firmware versionsThe figure shows an example where several inputs are used to trigger an output. With the OR function, any one of theinputs can trigger the output.
