About ROM operation/high-speed RAM operation function
5Functions set with parameters
* About backup
During the ROM operation, programs are backed up from the ROM area, and parameters and error log files
are backed up from the RAM area.
* About direct execution
While in the ROM operation, local variables cannot be rewritten by direct execution.
* About the continue function
While in the ROM operation, the continue function is disabled even if it is set.
The continue function saves the execution status at the time of power OFF, and starts operating from the
saved status the next time the power is turned on.
*About extension memory
When extension memory is installed or removed during the ROM operation, an error will occur. Install or
remove extension memory only after switching to the RAM operation.
* About operating times
The operating times (power ON time and remaining battery time) are updated regardless of switching
between the ROM and RAM operations.
* About production information
The production information monitor (program operation count, cycle time, etc.) of Personal Computer sup-
port software is not added or updated during the ROM operation.
