CHAPTER 4: SETPOINTS FLEXLOGIC
850 FEEDER PROTECTION SYSTEM – INSTRUCTION MANUAL 4–417
The following cases depict the nature of the three time stamps after a file conversion.
In a typical scenario where both the FlexLogic Designer and FlexLogic Editor are used for
configuring FlexLogic, the updated time stamps will appear as shown in the following
figure.
Logic Designer: This entry can be used to initiate the launch of the ‘Logic Designer’ screen.
Once chosen, the existing ‘FlexLogic Equation Editor’ screen is set to Read-only and then
the ‘Logic Designer’ screen launch is initiated.If the user wants to re-visit the FlexLogic
Editor Screen, any existing read-only screen has to be closed first. Then, the screen has to
be re-opened. The FlexLogic Editor screen is now editable, again.
In order to maintain synchronization of FlexLogic, the following update rules are defined.
For example, when a user tries to open the ‘FlexLogic Equation Editor’ of a particular
device or file.
• If the ‘Logic Designer’ screen is open and in Edit mode, a message prompts the user to
save any changes. The ‘FlexLogic Equation Editor’ is not launched.
• If the ‘Logic Designer’ is open and in saved mode (no edits to save or compile), the
‘Logic Designer’ screen is closed and then the ‘FlexLogic Equation Editor’ launch is
initiated.
