(The total data storage is for two PTs.) SW2-3 sets whichof these two banks is used for automatic transmission.Reference:S In the following cases, a mode setting error occurs.• More than one of the SW1-1 to SW1-3 switches are set to ON.• None of the SW1-1 to SW1-3 switches are set to ON.S In the following case, a protect setting error occurs.Transmitting to the write destination has been disabled by the setting forSW2-1 or SW2-2.S In the following cases, a data transmission error occurs.• An attempt is made to transmit data other than the system program to PTSystem Program Area.• An attempt is made to transmit the system program to PT Screen DataArea.S For details on mode setting errors and protect setting errors, refer to ErrorsWhen Using a Memory Unit (page 36).Writing Screen Data to aMemory Unit UsingAutomatic Transmission(PT to Memory Unit)In this mode, system program or the screen data in the NT21 is forcibly written tothe Memory Unit irrespective of the setting status of the NT21.This mode is convenient if the touch panel is broken and touch switch operationis 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 inthe specified Area up until that point is lost (if the data is written into only oneBank, the other Bank will not be affected).Method of ExecutionUse the following procedure to write the system program or screen data in theNT21 to the Memory Unit by automatic transmission.1, 2, 3...ON11.
Check that the power supply to the NT21 is OFF, then set the DIP switches ofthe Memory Unit as follows after installing Memory Unit to NT21.ON234SW112SW2SW1-4 ON: System programOFF: Screen data34SW2-4 ON: System/Screen transmitted simultaneouslyOFF: System/Screen not transmitted simultaneouslySW2-3 ON: Bank 1OFF: Bank 0It 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 operatingerrors.Reference:S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disablesthe setting of SW1-4.S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disablesthe setting of SW2-3, writes the system program into bank 0, and the screendata into bank 1 at all times.33SectionUsing a Memory Unit3-52.
Switch the NT21 power ON.The screen data is automatically written into the Memory Unit. The screendata in the NT21 is preserved.The messages Preparing, Transmitting, Verifying, and Finished are displayed 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 themeans of the number of bytes and blocks (1 bank = 16 block = 1024k byte).RUN Indicator operates as follows according to the processing status.Preparing: flashes at intervals of 1 secondTransmitting: flashes at intervals of 0.5 secondVerifying: flashes at intervals of 0.5 secondFinished: lights up3.
Switch the NT21 power OFF, remove the Memory Unit.To operate NT21 continuously, switch the NT21 power back ON.Writing Screen Data tothe PT Using AutomaticTransmission (MemoryUnit to PT)In this mode, the system program or screen data in the Memory Unit is forciblywritten to NT21 irrespective of the setting status of the NT21.Since data transmission by this method is faster than when the NT Support Toolor system installer is used, it can save a lot of time.
When transmitting the samesystem program or screen data to multiple NT21, this mode becomes convenient.Reference: When data is written to the NT21, the data that has been stored up until that pointis lost. When the system program is changed, the operation of NT21 also changes.Method of ExecutionUse the following procedure to write the screen data in the Memory Unit to theNT21 by automatic transmission.1, 2, 3...ON11. Check that the NT21 power is OFF, then set the DIP switches on the MemoryUnit as follows after installing Memory Unit to NT21.ON234SW112SW2SW1-4 ON: System programOFF: Screen data34SW2-4 ON: System/Screen transmitted simultaneouslyOFF: System/Screen not transmitted simultaneouslySW2-3 ON: Bank 1OFF: Bank 0It is not strictly necessary to set SW2-2 to OFF (to disable writing to theMemory Unit), but it is recommended to do so to avoid loss of data in theevent of operating errors.Reference:S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disablesthe setting of SW1-4.S Setting SW2-4 to ON (System/Screen transmitted simultaneously) disablesthe setting of SW2-3.
In this case, the data transmission becomes possibleonly if the data inside Memory Unit is in either of following combinations.Bank 0: system program, Bank 1: other than system programBank 0: other than system program, Bank 1: system programIf the combination is not as listed above, a data transmitting error occurs.S When writing the system program into the NT21, the type of system programinside Memory Unit and the PT model must correspond.34SectionUsing a Memory Unit3-52. Switch the NT21 power ON.The screen data is automatically written into the PT.The messages Preparing, Transmitting, Verifying and Finished are displayed on the screen in accordance with the progress of data writing.At the same time, the progress of data writing status is displayed by themeans of the number of bytes and blocks (1 bank = 16 block = 1024k byte).The RUN Indicator operates as follows according to the processing status.Preparing: flashes at intervals of 1 secondTransmitting: flashes at intervals of 0.5 secondVerifying: flashes at intervals of 0.5 secondFinished: lights up3.
Switch the NT21 power OFF, remove the Memory Unit.To operate NT21 continuously, switch the NT21 power back ON.Reading and Writing Databy Manual TransmissionIn this method, the direction of transmission and Area of the Memory Unit usedare set by touch switch operations at the NT21. Transmission can be executedwhile checking the settings.Reference: When data is written to the NT21 or Memory Unit, the data that has been storedup until that point is lost.Method of ExecutionUse the following procedure to write screen data using manual transmission.1, 2, 3...1.
Check that the NT21 power is OFF, then set the DIP switches on the MemoryUnit as follows.ON1ON2SW13412SW2Setting of SW1-4 not relevant34Setting of SW2-4 not relevantSetting of SW2-3 not relevantIn order to avoid loss of data in the event of operating errors, it is advisable toset SW2-1 and SW2-2 so as to disable writing to the Unit from which the datais to be read.2.
