The graphical user interface
5.6 Logic editor view
The Setting and Monitoring Tool includes a graphical Logic editor. The function logic
is program-med by using logic and application-specific function blocks. The inputs,
function blocks and outputs are positioned on a worksheet and are connected
correspondingly.
As soon as a MELSEC-WS CPU module is located in the Configuration area, the
Logic editor can be accessed via the tab of the same name.
The Logic editor window consists of the following sub-windows:
Menu bar with the menus Project, Device, Extras
Toolbar with icons for rapid access to menus that are often used
Tabs for switching between the Hardware configuration, Logic editor, Network
module [13] (if the project contains at least one network module), Report,
Diagnostics and Data Recorder view.
Specific toolbar for the logic editor with the following functions:
Add/Delete/Rename page, Print current page, Zoom, Copy/Cut/Paste/Delete
elements, Undo/Redo last action, Open dialog to edit logic result markers,
Show/Hide grid, Show grid of lines/dots, Show function block I/O description,
Search function block, Start simulation mode and Start forcing mode
Selection windows for Function block, Inputs, Outputs and Diagnostic inputs
FB preview window on the bottom left for displaying the important system
resources such as the number of used/available function blocks or the current logic
execution time (cycle time of the logic). When the cursor is moved over a function
block in the worksheet, additional information on this function block is displayed in
the FB preview window.
