* The memory unit stores screen data for one PT in each area (bank 0,
bank 1). (The total data storage is for two PTs.) SW2-3 sets which of
these two banks is used for automatic transmission.
Reference: S 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.
S In the following case, a protect setting error occurs.
• Writing to the write destination has been disabled by the setting for SW2-1
or SW2-2.
S For details on mode setting errors and protect setting errors, refer to Errors
When Using a Memory Unit (page 3 to 25).
In this mode, the screen data in the NT31/NT31C is forcibly written to the
memory unit irrespective of the setting status of the NT31/NT31C.
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 opera-
tion 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 (there is no effect on the other area).
Method of Execution
Use the following procedure to write the screen data in the NT31/NT31C to the
memory unit by automatic transmission.
1, 2, 3... 1. Check that the power supply to the NT31/NT31C is OFF, then set the DIP
switches of the memory unit as follows after installing the memory unit in
NT31/NT31C.
OFF
SW1
SW2-3 ON: Bank 1
OFF: Bank 0
SW2

It is not strictly necessary to set SW 2-1 to OFF (to disable writing to the
memory unit), but it is recommended to do so to avoid loss of data in the
event of operating errors.
2. Switch the NT31/NT31C power ON.
The screen data is automatically written into the memory unit. The screen
data in the NT31/NT31C is preserved.
The messages Preparing, Transmitting, Verifying, and Finished are dis-
played on the screen in accordance with the progress of data writing.
When messages Preparing, Transmitting, and Verifying are displayed, the
RUN LED flashes, and when the message Finished is displayed, the RUN
LED lights.
3. Switch the NT31/NT31C power OFF, remove the memory unit. To operate
NT31/NT31C continuously, switch the NT31/NT31C power back ON.
In this mode, screen data is forcibly written from the memory unit to the
NT31/NT31C irrespective of the setting status of the NT31/NT31C.
Since data transmission by this method is faster than when the Support Tool is
used, it can save a lot of time. When transmitting the same system program or
screen data to multiple NT31/NT31C, this mode becomes convenient.
