Omron NT31 NT31C manual Method of Execution

Using a Memory Unit (-Vj Versions) Section 3-5

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 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 (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 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 memory unit to NT31/NT31C.

SW1	SW2	SW2-4 ON: System/Screen transmitted simultaneously
		OFF: System/Screen not transmitted simultaneously

SW2-3 ON: Bank 1

OFF: Bank 0

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 operating errors.

Reference: S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disables the setting of SW1-4.

SSetting 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.

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.

At the same time, the progress of the data writing status is displayed by the means of the number of bytes and blocks (1 bank = 16 block = 1024k byte).

RUN LED operates as follows according to the processing status.

Preparing	: flashes at intervals of 1 second
Transmitting	: flashes at intervals of 0.5 second
Verifying	: flashes at intervals of 0.5 second
Finished	: lights up

3.Switch the NT31/NT31C power OFF, remove the memory unit.

To operate NT31/NT31C continuously, switch the NT31/NT31C power back ON.
