7.5 Using the SD card as the main memory or
additional memory
The SD card can be used as main or as additional memory.
Figure 7-6 shows how to proceed to use the SD card as the main or additional memory.
Figure 7-6 Procedure for using the SD card as the main or additional memory
7.5.1 Main memory
If you use the SD card as the main memory, all application-specific data is stored on the SD
card.
The SD card is recognized during the initialization phase of the controller.
• Make sure that the SD card is inserted before switching on the controller to enable the
controller to use it as the main memory.
Do not remove the SD card
during operation
If you are using the SD card as the main memory, you may not remove the SD card during
operation.
Should the SD card be accidentally removed during operation, the controller signals an er-
ror, stops processing the application program, and switches to the READY state. The FAIL
LED indicates an error. If an online connection to PC Worx Engineer is active, a display ap-
pears in the cross-functional area indicating that the SD card was unintentionally inserted or
removed.
Changing operating modes
If you are operating the controller without an SD card, all application-specific data is stored
on the internal parameterization memory of the controller.
When changing operating modes (operating the controller with/without SD card), please
note the following:
Change: operation without
SD card  operation with
SD card
To change the controller mode from “operation without SD card” to “operation with SD card”,
proceed as follows:
• Switch off the supply voltage of the controller.
• Insert the SD card, see Section 4.5.
