6-9-10 Setting the Resume Function
The NT631/NT631C has a function to keep the contents of the memory tables
even when the power to the NT631/NT631C is OFF and write back them to
the host when the power is turned ON.
If the resume function is OFF, the memory tables are initialized to these initial
values on switching to the RUN mode. If the resume function is ON, these are
not initialized and are kept the battery-backed up contents.
When the memory table is initialized, its contents are reset to the initial state
that is set by the Support Tool.
When the system is started up the next time, the screen is displayed using the
previous contents of the memory table.
• ON: The resume function is used.
• OFF: The resume function is not used.
The default (factory) setting is OFF.
Reference: • When the voltage of the NT631/NT631C’s built-in battery becomes low,
the memory table contents cannot be retained even if ON is set for the
resume function.
• For details on the resume record function, refer to 2-15-3 Resume Func-
tion in the Reference Manual.
