Memory Cassette Functions
Section 6-6
Reading Data from
the Memory Cassette
to the CPU Unit
The CX-Programmer's Memory Cassette function can be used to read data
stored on the Memory Cassette, and transfer it to the corresponding areas in
the CPU Unit. The data to be read can be individually specified.
This function can be used for operations such as writing the required backup
data to the CPU Unit for maintenance.
Precautions when
Using the Memory
Cassette Data
Transfer Function
• In order for Memory Cassette data to be transferred, the Memory Cas-
sette must be mounted in the CPU Unit.
• The BKUP indicator will light while data is being transferred to or verified
in a Memory Cassette. Never turn OFF the power to the PLC or remove
the Memory Cassette while the BKUP indicator is lit. Doing either may
make it impossible to use the Memory Cassette.
• Memory Cassette data transfers and verification are possible only when
the CPU Unit operating mode is PROGRAM mode. The Memory Cassette
transfer function cannot be used in either RUN or MONITOR mode.
• When using automatic transfer from a Memory Cassette at startup, be
sure to transfer the data to the Memory Cassette if any changes are made
using online editing.
• The operating mode cannot be switched from PROGRAM mode to RUN
or MONITOR mode while a Memory Cassette data transfer or verification
is in progress.
• The following table shows whether data transfers are enabled when the
CPU Unit is protected in various ways.
Programs, parameters, DM initial
values, comment memory, etc.
