CHAPTER 4: INTERFACES FLEXLOGIC DESIGN USING ENGINEERC60 BREAKER PROTECTION SYSTEM – INSTRUCTION MANUAL 4-654Create events every minute, then every 100 msFigure 4-68: One-minute timer turns on LED and creates events every 100 msPreparation — Under Settings > Inputs/Outputs > Virtual Outputs, virtual output 5 is named EVStart, 6 is namedEVTriggered, and 7 is named EVMakeEventTop logic — One-minute timer triggerMiddle logic — Turn on LED 17 for 10 seconds when trigger startsBottom logic — Create events at 100 ms intervals for the same 10 second period4.4.1.2 Add existing FlexLogic equationsA logic diagram can be created using existing FlexLogic equations (this section) or by creating new ones (next section).When using existing equations, you modify them in the FlexLogic Equation Editor in the Offline Window area, then applythem.To create a logic diagram using existing FlexLogic equations:1. In the Offline Window area, modify the FlexLogic for the device under FlexLogic > FlexLogic Equation Editor. If thedevice is not listed, right-click the device in the Online Window area and select the Add Device to Offline Windowoption.Upon saving the modified FlexLogic, a yellow icon appears for the device in the Offline Window area to indicate thatthe logic differs from the Online device.2. In the Offline Window area, access Engineer for the device, then Logic Designer. The logic opens.3. Click the Edit > Auto Populate Workbook menu item. If the software prompts if you want to keep or discard existingsheets, either is acceptable, with the older excluded sheeted being denoted by brackets, such as < Sheet 1 >. The logicdisplays in the various tabs. The FlexLogic created in the equation editor appears in Sheet 1, for example.4.4.1.3 Create logic diagramUpon access of the Logic Designer, the FlexLogic equations of the device display. You can create new logic in new sheets ormodify the ones that display.This procedure uses input / output logic as an example.To create a logic diagram:1. In the Offline Window area, access Engineer for the device, then Logic Designer. If the device is not listed, right-clickThe FlexLogic Equation Editor window is in view-only mode when the Logic Designer is open. To instead work in theFlexLogic Equation Editor, close the Logic Designer window, then re-open the FlexLogic Equation Editor.
