Memory Cassette Functions
Section 6-6
Data that Can be
Stored on a Memory
Cassette
The following data can be stored on a Memory Cassette.
The areas for storing various types of data have fixed allocations in the Mem-
ory Cassette, and a single Memory Cassette corresponds to a single CPU
Unit.
Therefore it is not possible to simultaneously store multiple items of the same
type of data (e.g., two user programs).
Also, the data can only be read to a CPU Unit. It cannot be directly managed
from a personal computer like files.
The only data that can be stored on a Memory Cassette is the data from a
CPU Unit.
Note
The CX-Programmer's function for saving DM initial values is used for saving
the values in the DM Area (D0 to D32767) to the built-in flash memory as ini-
tial values. By means of a setting in the PLC Setup, these initial values can
then be automatically written to the DM Area (D0 to D32767) when the power
is turned ON.
