Memory Card Function
The memory card is optional and serves as memory in addition to the internal
memory in the fieldbus controller. The user program, user data, the source code of
the project or device settings can be saved on the memory card and thus already-
existing project data and programs can be copied to one or more fieldbus
controller(s).
If the memory card has been inserted, it is incorporated into the directory structure
of the internal file system of the fieldbus controller as drive S:. This way, the
memory card can be addressed like a changeable medium on a PC.
Deactivate write protection!
In order to be able to write data on the memory card, you must deactivate the
small push switch for the write protection setting. This switch is on one of the
long sides of the memory card.
The function of the memory card in normal operation and possible errors that can
arise when using the memory card will be described in the following sections for
various steps during operation:
•
System start (automatic loading of device settings from the memory card)
•
Back-up function (saving of device settings on the memory card)
•
Restore function (loading of device settings from the memory card)
•
Inserting a memory card during ongoing operation
•
Removing the memory card during ongoing operation
•
SPS access to the file system of the memory card
