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

Writing Screen Data to the PT Using Automatic Transmission (Memory Unit to PT)

In this mode, the system program or screen data in the memory unit is forcibly written to NT31/NT31C irrespective of the setting status of the NT31/NT31C. Since data transmission by this method is faster than when the Support Tool or system installer 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.

Reference: When data is written to the NT31/NT31C, the data that has been stored up until that point is lost. When the system program is changed, the operation of NT31/NT31C also changes.

Method of Execution

Use the following procedure to write the screen data in the memory unit to the NT31/NT31C by automatic transmission.

1, 2, 3... 1. Check that the NT31/NT31C power is OFF, then set the DIP switches on 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 SW2-2 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.

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. In this case, the data transmission becomes possible only if the data inside memory unit is in either of following combinations.

Bank 0: system program, Bank 1: other than system program

Bank 0: other than system program, Bank 1: system program

If the combination is not as listed above, a data transmitting error occurs.

SWhen writing the system program into the NT31/NT31C, the type of system program inside memory unit and the type of PT unit must be corresponding.

2.Switch the NT31/NT31C power ON.

The screen data is automatically written into the PT.

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

The 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.
