Cause
Allocated words have not been
set for the PT status control area
and PT status notify area.
The type of registered screen
data does not match that at the
NT31/NT31C.

the screen number set in the PT
status control area or the Initial
Screen set with the Support Tool.
Or the screen number which
does not exist are registered.

cable) inside the NT31/NT31C is
disconnected.
The memory switches have been
initialized due to discovery of an
error in the memory switch
settings.
There is an error in the date/time
values due, for example, to low
battery voltage.
Initialization has been executed
because of an error in the
backup data area.
Protocol settings for serial port A
and serial port B are
mismatched.
