Continuous buzzer2. Short intermittent buzzer3. Long intermittent buzzer58SectionAreas for Control/Notification2-2When stopping the buzzer by PT status control bit operation, set all three of thebits above to 0 (OFF).Reference:S The buzzer will actually sound only when the Buzzer Sound memory switch ofthe PT is set to ON.S The buzzer can also be stopped in other ways: by using a touch switch to whichthe buzzer stop attribute has been assigned (page 301), or by setting thescreen attribute that stops the buzzer sound (page 45).S The buzzer can also be controlled by using the Buzzer screen attributes (page45).S Even if the buzzer is controlled using PT status control bit operation, changesin the displayed screen may cause the status of the buzzer to changed depending on the buzzer setting in the screen attributes. Reset the PT status controlbits if necessary.Display History Initialization (Bit 11)This bit is used to initialize the display history recorded in the PT.When it is switched from 0 (OFF) to 1 (ON), the display history in the PT is initialized.After initialization, return its status to 0.Reference: The display history can also be initialized from the MEMORY INIT.
MENU screenunder the System Menu of the PT.Backlight Mode (Bit 8)The backlight mode is used for controlling the backlight of the PT. This bit is invalid in the NT631.The status of bit 8 has the following effects.• 1 (ON):lit• 0 (OFF):flashingScreen Printing (Bit 7) (Not Supported by the NT21)Hard copies of the screen can be made when a printer is connected to the PT.When bit 7 is set from 0 (OFF) to 1 (ON), printing of the currently displayedscreen starts. Note that it is not possible to stop printing while printing is in progress.Check that bit 7 (printer operating status) of the PT status notify area is in the 0(OFF) status before starting printing.When printing starts and bit 7 has been set to the 1 (ON) status, return the screenprinting bit to 0 (OFF).Reference:S It is also possible to print screens by using a touch switch assigned the Printscreen function.S The printer type (control protocol) and printing method, are set with thememory switches of the PT.PT Window Opening Bit (Bit 6)The PT window opening bit is used to disable opening of a window by operationat the PT.The status of bit 6 has the following effects.59SectionAreas for Control/NotificationBit 62-2Function0 (OFF) Windows can be opened by operation at the PT.1 (ON)Windows cannot be opened by operation at the PT (windows that arealready open can be closed by operation at the PT).Also, when a keyboard screen attribute is designated for a screen, thewindow will not open when the screen is switched by operation at the PT.Reference: If the interlock function has been set for a touch switch, window operations fromthe touch switch can also be disabled by turning OFF the corresponding interlockbit in the PC.Numeral/Character String Input (Bit 5)This bit is used to disable the input of numeric values and character strings intonumeral setting/character string input fields by operation at the PT.
It also controls input from thumbwheel switches, recipe objects, and bar code readers.The status of bit 5 has the following effects.Bit 5Function0 (OFF) Input into numeral setting input fields and character string input fields ispossible.1 (ON)Input into numeral setting input fields and character string input fields isdisabled (it is also not possible to change the contents of numeral/character string memory table entries by operation at the PT, such as copyingmemory table entries with touch switches).The contents of numeral/character string memory table entries can bechanged without restriction from the host. It is also possible to copymemory table entries using the PT status control area.Reference: If the interlock function has been set for a numeral input, character string input,thumbwheel switch, or recipe object, the input can also be disabled by turningOFF the corresponding interlock bit in the PC.PT Screen Switching (Bit 4)This bit is used to disable screen switching by operation at the PT.The status of bit 4 has the following effects.Bit 4Function0 (OFF) Screen switching by operation at the PT is possible.1 (ON)Screen switching by operation at the PT is not possible.The screen can be switched by the instructions from the host (screenswitch setting word of the PT status control area, bit memory table operations).Reference: If the interlock function has been set for a touch switch, screen switching by thetouch switch can also be disabled by turning OFF the corresponding interlock bitin the PC.Memory Table Copy Execute (Bit 3), Memory Table Copy Type (Bit 2)The memory table copy execute and memory table copy type bits are used tocopy data between memory table entries in the PT by PT status control area operations.Proceed as follows to copy between memory table entries using the PT statuscontrol area:Operation1, 2, 3...601.
Set the numbers of the copy source and copy destination memory table entries for copy source memory table entry number (word n + 1) and copy des-SectionAreas for Control/Notification2-2tination memory table entry number (word n + 2) of the PT status controlarea.2. Set the type of the memory table to be copied for memory table copy type (bit2) of the PT status control bits (word n + 3) as follows:• 1 (ON):When copying between numeral memory table entries• 0 (OFF): When copying between character string memory table entries3. Set 1 (ON) for memory table copy execution (bit 3) of the PT status controlbits (word n + 3).Memory table entry data is copied.4. After copying has been executed, return memory table copy execution (bit3) to 0.Reference:S If the display method or number of registered words is different for the copysource and copy destination memory table entries, the data may not be displayed correctly.S If the contents of memory table entries are changed by PT status control areaoperation, the change in memory table contents is not notified by the PT statusnotify area.S Memory table entries are copied differently when the PT is set to NT20S orNT30/620 compatible mode.
Refer to Appendix C for details on the NT20S andNT30/620 compatible modes.Alarm History Initialization (Bit 1)This bit is used to initialize the alarm history recorded in the PT.When it is switched from 0 (OFF) to 1 (ON), the alarm history in the PT is initialized.After initialization, return its status to 0.Reference: The alarm history can also be initialized from the MEMORY INIT. MENU screenunder the System Menu of the PT.2-2-2 PT Status Notify Area (PT to Host)The PT status notify area is provided to notify the host of changes in the status ofthe PT. The host can determine the status of the PT by reading this area.The PT status notify area is configured as two consecutive words as shown below.
The first word (word m) is set in the Control/Notify Area settings in the PTconfiguration settings made with the Support Tool.15 14 13 12 11 10 9Word8765432mNumeral/character string memory table number(4-digit BCD or hexadecimal value)m+1PT status notify bits010 BitContent updatememory table00PT statusReference: The configuration and functions of the PT status notify area are different whenthe PT is set to NT20S or NT30/620 compatible mode.
