- In the following cases, a mode setting error occurs.
- More than one of the SW1 switches are set to "ON".
- None of the SW1 switches are set to "ON".
- In the following case, a protect setting error occurs.
- Transmitting to the write destination has been disabled by the setting for
SW2-1 or SW2-2.
- In the following cases, a data transmission error occurs.
- An attempt is made to transmit data other than the system program to PT sys-
tem program area.
- An attempt is made to transmit the system program to PT screen data area.
- For details on mode setting errors and protect setting errors, refer to "Errors
When Using a Memory Unit" (page 54).
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 operation is
not possible, or if someone unfamiliar with touch switch operation at the operation
site is using the system.
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 affeceted).
S Method of execution
Use the following procedure to write the screen data in the NT631/NT631C to
the memory unit by automatic transmission.
(1) Check that the power supply to the NT631/NT631C is OFF, then set the DIP
switches of the memory unit as follows after installing memory unit to
NT631/NT631C.
SW1
SW1-4 ON: System program
OFF: Screen data
It is not strictly necessary to set SW2-1 to "OFF" (to disable writing to the
PT), but it is recommended to do so to avoid loss of data in the event of mis-
operation.
- Setting SW2-4 to ON (System/Screen transmitted simultaneously) disables the
setting of SW1-4.
- Setting SW2-4 to ON (System/Screen transmitted simultaneously) disables the
setting of SW2-3, writes the system program into bank 0, and the screen data
into bank 1 at all times.
SW2
SW2-4 ON: System/Screen transmitted simultaneously
OFF: System/Screen not transmitted simultaneously
SW2-3 ON: Bank 1
OFF: Bank 0
