4-76 L30 LINE CURRENT DIFFERENTIAL SYSTEM – INSTRUCTION MANUALFLEXLOGIC DESIGN USING ENGINEER CHAPTER 4: INTERFACES4To import a file from a device:1. Close all open files in Engineer that relate to the device, else a message displays to that effect, for example to closethe FlexLogic view associated with the file. When the file is not associated with a live device, a message displays tothat effect; you need to identify the device to which you want to send the file. The order codes must match.2. Right-click the device in the Online Window area and select the Add Device to Offline Window option. After you entera name for the file, it is written to the Offline Window area.4.4.3 Monitor logicAfter creating the logic diagram, validating it, and uploading the FlexLogic to a device, the results from the device can beviewed.The following checks are performed automatically when switching from design to monitoring, and prompts display whennecessary:• Verify that the order code of the linked relay matches the settings file• Verify that the version of the linked relay matches the settings file• Verify that the FlexLogic Equation Editor of the linked relay matches the settings file. Solution: Compile the FlexLogiclogic diagram and send the settings file to the relay.• Verify that the FlexLogic Timers of the linked relay match the settings file. Solution: Compile the FlexLogic logicdiagram and send the settings file to the relay.• If the settings file contains a serial number lock, then verify that the serial number of the linked relay matches thesettings fileTo view results:1. In the Offline Window area of the software, expand the Engineer entry for the device.2. Double-click the Logic Designer entry and Compile the logic.3. Double-click the Logic Monitor entry, or click the M button in the toolbar at the top of the window. With successfullaunch, the logic displays and a green indicator displays at the bottom of the tab.When the file is not associated with a live device, a message displays to that effect; you need to identify the device towhich you want to send the file. The order codes must match between the Offline Window and the Online Window.When the device is offline, a message indicates problems communicating with the device.When the devices are not synchronized, a message indicates the FlexLogic does not match the settings file. To sendthe offline file to the device, right-click the device name and select the Write Settings to Device option.When the state of a symbol is OFF, the symbol is shown in the default color or no color.When a symbol's state changes to ON, the symbol and connection line turns green.The state of some symbols can either be unknown or the state transitions faster than the update interval. For thesetwo cases, the state of the symbol is considered 'UNKNOWN' and the symbol is outlined in red.The colors for the ON and Unknown state can be customized in the Preferences.The figure shows that the software is communicating with devices (square green indicator) and that a minor error ispresent (green box outline). In this case, the battery is weak and needs to be replaced. This can be viewed as theReplace Battery message on the front panel of the device and in the EnerVista software under Actual Values > FrontPanel > Front Panel or Display/Keypad.
