Writing Screen Data to a
Memory Unit Using
Automatic Transmission
(PT to Memory Unit)
In this mode, system program or the screen data in the NT631/NT631C is
forcibly written to the Memory Unit irrespective of the setting status of the
NT631/NT631C.
This mode is convenient if the touch panel is broken and touch switch opera-
tion is not possible, or if someone unfamiliar with touch switch operation at the
operation site is using the system.
Reference:
When screen data is written to the Memory Unit, the data that has been
stored in the specified area up until that point is lost (if the data is written into
only one Bank, the other Bank will not be affected).
Method of Execution
Use the following procedure to write the screen data in the NT631/NT631C to
the Memory Unit by automatic transmission.
