5.14.1.3 Backup Data Restoration

To restore backup data, perform the reversed backup operation (Enter the setting for the personal computer in [A:Dev], and
the setting for CNC controller in [B:Dev]).
The PLC must be STOP before restoration is started.

5.14.1.4 Precautions

Precautions for input/output between different NC models or between systems with different additional
specification status
If the large capacity PLC (256 kilo steps)/large capacity PLC (512 kilo steps) additional specification is enabled, the size of
sequence programs that can be stored in CNC is increased.
USERPLC.LAD output while Large PLC capacity (256 kilo steps)/Large PLC capacity (512 kilo steps) additional specification
is enabled may not be input to the system in which the enabling/disabling of Large PLC capacity option is switched,
depending on the size of the sequence programs stored when output.
[Large capacity PLC additional specification, type of input USERPLC.LAD, and operation]
Large capacity PLC additional specification is
disabled in M800V series
Large capacity PLC (256 kilo steps) additional
specification is enabled in M800V series
Large capacity PLC (512 kilo steps) additional
specification is enabled in M800V series
When the PLC project extension (3 projects)/PLC project extension (6 projects) (additional specification) is enabled, the
number of projects and device points that can be used increases when the multi-project function is active.
The USERPLC.LAD output while the PLC project extension (3 projects)/PLC project extension (6 projects) (additional
specification) is enabled may not be input to the system whose PLC project extension option is switched between enabling/
disabling, depending on the number of projects and device points set at the time of the output of USERPLC.LAD file.

fication is disabled in M800V series

tional specification is disabled in M800V

tional specification is disabled in M800V
