If a touch switch displayed in a corner is pressed first, thetouch switch will function and the System Menu will not be displayed. In particular, when the touch switch has switch screen function, as a result of screenswitch over, it means the corner is not pressed even if it is kept pressing. To successfully call the System Menu, first press a corner where no touch switch is displayed, and then press any other corner regardless of the presence of a touchswitch.Reference: With the NT21, the System Menu can be displayed even if the screen has touchswitches registered at all four corners.Pressing a Touch Switch That Displays the System MenuThere is a control key that has the function of displaying the System Menu.By registering a touch switch for the System Menu display ([MENU]) on a screenwhen creating it, the System Menu can be displayed just by pressing this switch.Selecting Menu Items108The menu items in the System Menu are displayed on the NT21 screen as touchswitches.
Menu items can be selected simply by pressing them.Operation Modes and the System MenuSection6-3Example: Displaying the MAINTENANCE MODE MENU screen by pressingMaintenance Mode in the System Menu.Press Maintenance Mode.Returning from theSystem Menu to the RUNModeReturn to the RUN mode by selecting Quit in the System Menu and other menus.Reference: The NT21 does not return to the RUN mode automatically if no operations areperformed.109SectionMemory Initialization6-46-4Memory InitializationThe NT21 has the following initialization functions. Use them as necessary.• Clearing screen dataPage 110• Initializing memory tablesPage 114• Initializing memory switchesPage 116• Initializing display history record dataPage 112• Initializing alarm history record dataPage 113• Initializing recipe tablesPage 117Reference: If writing to the screen data memory is prohibited by the System Setting setting inthe System Installer mode, memory initialization is not possible.6-4-1 Clearing Screen DataUse this function if the screen data has been corrupted and the NT21 cannot bestarted up correctly.This operation clears (initializes) only the screen data and contents of the mathematical table.
The memory switch settings, display history data, alarm historyrecord data, and recipe data are retained.Reference:S When this function is used, all of the screen data contents registered in theNT21 up to that point are cleared.
Check that the created screens are backedup at the NT Support Tool before using it.S The screen data can be cleared in the System Installer mode too (page 119).S The following types of data can be initialized individually.Contents of numeral and character string memory tables (page 113)Memory switch settings (page 114)Display history record data (page 112)Alarm history record data (page 113)Recipe data (page 117)110SectionMemory Initialization6-4Clear the screen data by following the menu operations from the MaintenanceMode Menu as shown below.Select Memory Init..Select Screen Data.Select Yes.The screen data is cleared.
During clearance, the message Erasing Now... is displayed.If No is selected, the NT21 returns to the MEMORY INIT. MENU screen withoutclearing the screen data.On completion of screen data clearance, the NT21 returns to the MEMORY INIT.MENU screen.After the screen data has been cleared, if an attempt is made to set the NT21 tothe RUN mode before screen data has been transmitted from the NT SupportTool or Memory Unit, an error message will be displayed and the RUN mode willnot be established.111SectionMemory Initialization6-46-4-2 Initializing Display History Record DataThe display history record function keeps a record of the order of display of thescreens displayed during operation, and the number of times each screen is displayed.
These records are kept only for screens for which the History attributehas been set.The maximum number of records is 1024 for sort by occurrence (order of displayoccurrence) and 255 for sort by frequency (order of the number of times eachscreen has been displayed).Use the display history record initialization function to clear the history recorddata to 0, for example when the screen data has been changed, etc. Also, if Display History (Use Ring Buffer) under History Setting of System in PT Configuration (Tools) has not been checked, no more records will be stored after the maximum number of records has been kept, and therefore the records must be periodically initialized.
If Display History (Use Ring Buffer) is checked, when themaximum number of records is reached the oldest record is deleted and thenewest data is recorded.Reference:S The NT21 also allows the display history record data to be initialized by controlling the PT Status Control Area from the host. For details, refer to 2-2-1 PTStatus Control Area in the Reference Manual.S If the optional battery is not installed, the display history record data will be initialized when the PT’s power is turned OFF.112SectionMemory Initialization6-4Initialize the display history record data by following the menu operations fromthe Maintenance Mode Menu as shown below.Select Memory Init..Select Display History.Select Yes.The display history record data is initialized.During initialization, the message Initializingis displayed.If No is selected, the NT21 returns to the MEMORY INIT.
MENU screen withoutinitializing the display history record data.On completion of display history record data initialization, the message Finishedis displayed and the NT21 returns to the MEMORY INIT. MENU screen.6-4-3 Initializing Alarm History Record DataThe alarm history record function continually checks the status of host bits thathave been designated in advance in the bit memory table, and records the timewhen any of the bits is set to 1 (comes ON), and the number of times that each bitcomes ON.The maximum number of records is 256 for sort by occurrence (order of erroroccurrence) and 255 for sort by frequency (order of the number of times eacherror has occurred).Use the alarm history record initialization function to reset the alarm history record data to 0, for example when the screen data has been changed, etc.
Also, ifAlarm History (Use Ring Buffer) under History Setting in the PT EnvironmentSettings – System Settings has not been checked, no more records will bestored after the maximum number of records has been kept, and therefore therecords must be periodically initialized. If Alarm History (Use Ring Buffer) ischecked, when the maximum number of records is reached the oldest record isdeleted and the newest data is recorded.113SectionMemory InitializationReference:6-4S The NT21 also allows the alarm history record data to be initialized by controlling the PT Status Control Area from the host. For details, refer to 2-2-1 PTStatus Control Area in the Reference Manual.S If the optional battery is not installed, the alarm history record data will be initialized when the PT’s power is turned OFF.Initialize the alarm history record data by following the menu operations from theMaintenance Mode Menu as shown below.Select Memory Init..Select Alarm History.Select Yes.The alarm history record data is initialized.During initialization, the message Initializingis displayed.If No is selected, the NT21 returns to the MEMORY INIT.
