For CV-series PLCs memory cards can be either RAM, EPROM, or EEPROM. EPROM and EEPROM cards can
only be written to using the Memory Card Writer.
For CS1-series PLCs memory cards can be either Compact Flash disk or configured EM memory.
There are three ways in which memory cards can be accessed:
♦
They can be read from/written to during an online operation using programming software;
♦
By instruction via a program in the PLC;
♦
Using the Memory Card component;
Refer to the associated PLC manual for further information.
The Memory Card component automatically detects whether the memory card is in place or not. An error message
is displayed if it is detected that the memory card has been removed whilst the Memory Card component is active.
Files held on the memory card can be compared with data in the PLC. File formats can be one of four types:
♦
.LDP indicates partial program area files;
♦ .OBJ indicates full program area files;
♦
.STD indicates PLC setup area files;
♦
.IOM indicates any other type of file.
The CS/CJ-series PLC also supports the configuration of EM memory as file memory. Providing the EM Table
Setting Enabled option from the Settings menu is set within the PLC Setup component whilst in Program mode.
Refer to Chapter 4 - PLC Setup Component for further details.
A fitted memory card on CV-series PLCs or Compact Flash card on CS/CJ-series PLCs must be formatted to be
used as a file storage device. Setting a CS1-series PLC as file memory in the PLC Setup component automatically
formats EM file memory for use in the Memory Card component.
Memory Card Display
The Memory Card component can be manipulated in the same manner as most Microsoft Windows displays to
control what is displayed; for example, expansion of the file storage hierarchy.
The left pane displays the content, in terms of Devices, Networks and Points.
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 left
pane.
Select the Large Icons button from the toolbar to display the content of the right pane as large
icons.
Select the Small Icons button from the toolbar to display the content of the right pane as small
icons.
Select the List button from the toolbar to display the content of the right pane as a list.
Select the Details button from the toolbar to display the content of the right pane with
associated details.
Use the following procedure to copy or move information from or in the PLC Memory component.
1, 2, 3… 1. Select an item, or items, in a window. More than one item can be selected by pressing Shift
and selecting another item to extend the selection, or by pressing Ctrl and selecting another
item to add to the selection.
2. Select the Copy button from the toolbar to copy the item, or the Cut button from the
toolbar to move the item.
3. Select an area to move the items to, for instance copying data area values into another data
area.
