21.3 Saved Data Content
The following data is saved on the memory cassette.
*1. This function is supported in FX
3U
PLC Ver. 3.10 or later.
Do not connect a memory cassette with special parameters saved to any FX
3U
PLC earlier than
Ver. 3.10.
*2. This function is supported in GX Works2 Ver. 1.73B or later.
*3. The total size of the pr co file registers must not exceed the maximum capacity of
the memory cassette.
*4. The maximum number of points for the memory capacity, comments, and file registers, can be
specified when the FX
3U(C)
programming tool is selected. The maximum number of points cannot be
specified when a programming tool other than the FX
3U(C)
is selected.
*5. It is possible to check the symbolic information capacity using the memory capacity calculation
(offline) of GX Works2.
Refer to the GX Works2 Version 1 Operating Manual (Common) for details.
Cautions on using the symbolic information
The FX
3U
PLC Ver. 3.00 or later can store symbolic information.
Note the following cautions when using symbolic information.
• When symbolic information is stored, it is deleted if the memory capacity set by parameters is changed.
After changing the memory capacity, write the symbolic information again.
• Memory cassettes (except for the FX
3U
-FLROM-1M) which are storing symbolic information can be used
by FX
3U
PLCs whose version is earlier than Ver. 3.00. In this case, the FX
3U
PLC operates, but the written
symbolic information is invalid.
• For writing symbolic information and changing the set values of timers and counters using a peripheral
device, it is recommended to create programs with set values specified indirectly.
If the set values are specified directly, programs cannot be restored from symbolic information after the set
values are changed.
