CHAPTER 2
PLC Memory Component
This chapter describes the PLC Memory component and its ability to allow the user to view, edit and monitor
either channels (words) or individual bits in areas of the PLC.
The PLC Memory component allows viewing, editing and monitoring of PLC memory areas, monitoring and
forcing of bit addresses and symbols and forced status information.
The PLC Memory component displays the values of the memory area being accessed within the PLC. Areas to be
monitored are selected from the memory area workspace. The address workspace shows individual bits,
individual channel symbols and forced status information by selecting or entering specific PLC addresses or
symbol names. The current values of these areas are displayed in the PLC Memory component. There are no
values displayed when the PLC is offline.
The PLC Memory component can be forced to stay as the top window by selecting Always on top from the View
menu.
For moving, resizing, tiling, maximising, minimising and closing windows, refer to Microsoft Windows online
help for further information.
Access to the PLC Memory component is from the invoking application.
To close the PLC Memory window, select the Close button in the title bar.
The left pane, known as the Data Area Workspace, displays the current PLC in terms of its data areas and
addresses. The data areas that form part of the PLC memory differ depending on the PLC type. The status bar
provides instant help, displays the PLC and CPU type and describes the operating mode of the PLC.
The display of the Data Area Workspace can be controlled by selecting Data Area Workspace from the View
menu.
The toolbar and status bar can both be turned on or off. Select Status Bar from the View menu to control the
display of the status bar. Select Toolbar from the View menu to control the display of the PLC Memory toolbar.
To expand the hierarchy in the left pane, select this icon.
To collapse the hierarchy in the left pane, select this icon.
To view the content of a particular branch in the hierarchy, double-click on the item in the Data
Area Workspace: a window is displayed within the PLC memory component. The associated
icon in the Data Area Workspace changes to denote that a window has been opened. Multiple
windows can be opened at the same time.
Select the Close button in the window's title bar to close the window.
Columns can be resized using the Resize Column button from the toolbar to fit the visible
display area. These options are useful when changing data format, for instance to Binary.
