CHAPTER 7
Memory Card Component
This chapter describes the Memory Card component available to CV-series PLCs and CS/CJ-series PLCs and its
ability to store and transfer data. File storage is achieved by a File memory card for a CV-series PLC and a
Compact Flash or EM memory configured as 'file memory' for a CS1-series PLC.
Information can be transferred from the PLC to the memory card or from the memory card to the PLC. A saved
program can be transferred from the memory card to the program area during operation. Extended PLC setup and
program files can be automatically transferred at PLC startup if they are named autoexec.std and autoexec.obj
respectively.
It is possible to run the Memory Card component whilst the PLC is offline.
The Memory Card component can be forced to be displayed in focus by selecting the Always on top option from
the Options menu.
For moving, resizing, maximising, minimising and closing windows, refer to Microsoft Windows online help for
further information.
Access to the Memory Card component is from the invoking application.

Memory Card Operation

The appearance and behavior of the Memory Card component is similar to Microsoft Windows Explorer.
Differences between the Microsoft Windows Explorer exist within the Memory Card component when certain
functions are accessed. Refer to Microsoft Windows Explorer help, part of the standard Microsoft Windows
documentation for options and functions not described in this chapter but available within the Memory Card
component.
The status bar provides instant help, the PLC and CPU type, and quick reference information describing how
much space is available on a particular device for the selection in the left pane.
In addition to the devices and folders supported by the PC, the Memory Card component also displays the
connected PLC device. In terms of the device/folder structure of Microsoft Windows Explorer, the PLC contains
a Memory Card folder if available (i.e. if fitted), Program Area, IO Memory Area and Parameter Area. For a
CS/CJ-series PLC, a Memory Card folder can contain subfolders.
A memory card can be displayed for each connected PLC and allows their contents to be moved between
destinations. The operation is aborted if there is not enough space. Snapshots of PLC Memory areas can be taken
by transferring information from the Program Area, IO Memory Area or Parameter area to the Memory Card
folder.
Caution: Memory cards must be formatted prior to use.
Note:
In order to view or execute on the PLC a file from the memory card, the file must be
copied back to the PC folder. Double clicking on the files in the list has no action
associated with it since files cannot be opened across the communications connected to
the PLC.
