Itdisplays only the contents of the record at the point when it was displayed andthe displayed record remains the same even if the status of the bit memorytable changes after that.Alarm list and alarm history elements cannot be used with NT11S, NT20S andNT600S.173Alarm6-3-1Section 6-3Alarm ListIf a bit memory table in the check objective range goes ON, the alarm list elementdisplays the contents (alarm message) of the character string memory table (stringtable) which is allocated to the bit memory table. It is also possible to display thecorresponding image/library data.NoteIt is possible to switch the screen by operating the alarm list element by setting thescreen number to which the screen should be switched for the bit memory table.Bit memory tableScreenCharacter string memorytable (String table)WARNING HIGH TEMP.No.1AlarmlistWARNING HIGH TEMP. No.2Image/library dataPressmessage(1) When the bit memory table number in the specified range goes ON, the alarmlist element reads out the alarm message from the character string memorytable (string table) and displays the message at the alarm list area in thescreen.(2) If an operator touches the displayed alarm message, the specified image/library data will arrive.NoteThe alarm message and the image/library data to be displayed are specified according to the setting at the bit memory table.Operation procedureSelection using the menu bar:[Objects] → [Alarm] → [List]Selection using the drawing toolbar:Related elements and settingsBit memory table:174[Tools] → [Table] → Bit Memory(Refer to 7-4 “Bit Memory Tables”.)AlarmSection 6-3TerminologyFrameImage/library dataDisplay lineForegroundBackgroundLengthPage scroll touch switchMessageBackground Line scroll touch switchProperty setting[General]Position:Indicates the display position of the alarm list.(The attribute point is at the upper left corner of the alarm list)Size:Indicates the size of the alarm list.MessageLength:Specify the number of characters of the message to bedisplayed.Max.

of Bits Referenced: Specify the number of bit memory tables which arechecked by the alarm list element.GuidanceS Using a line scroll touch switch and a page scroll touch switch, you can scrollmessages in units of a line or a page within the alarm list display area.S With NT31, NT31C, NT631, and NT631C, to display a line scroll touch switchand/or a page scroll touch switch, set a check mark in the line scroll touch switchand/or a page scroll touch switch check box in the Property setting dialog box.176AlarmSection 6-3S With NT31, NT31C, NT631, and NT631C, a line scroll touch switch and a pagescroll touch switch are a part of an alarm list element.
Therefore, they cannot bemodified as a touch switch. They can be moved only when the alarm list is modified. For NT31, NT31C, NT631, and NT631C, the line and page scroll touchswitch can be moved by clicking the desired touch switch while holding down theShift key and Ctrl key. ([Edit Object] from [Edit] menu (or pop–up menu) and Inskey can also be used for this operation.)With NT30, NT30C, NT620S, NT620C, and NT625C, however, a line scrolltouch switch and a page scroll touch switch are independent elements and theirposition, size, and label can be changed as required. However, the touch switchfunction and the lamp setting should not be changed, otherwise the switch andthe lamp will fail to function correctly on PT.S To display the image/library data, set a check mark in the check box of [DisplayImage Lib] in the Property setting dialog box.S The procedure for editing the image/library data display area is shown below.(1) Specify only the image/library data display area (dotted line frame) while holding down the Shift key and Ctrl key.
(automatically enters to “Edit Object”mode)Green J marks (handles) are displayed surrounding the image/library datadisplay area.There are other methods to enter “Edit Object” mode. For details, refer to“Specifying an element consisting of multiple elements” (p123).(2) Specify the display size of the image/library data display area and move it asdesired.S If the size of the image/library data is smaller than the display area, the image/library data is displayed taking the lower left corner of the display area as the reference.Image/library data display areaImage/library dataReference: With NT31, NT31C, NT631, NT631C, if image/library data is larger than the image/library data display area, the area exceeding the display area will not be displayedon PT while the whole data is displayed on the Support Tool.
Be sure to set image/library data display area so that image/library data fits inside it.177AlarmSection 6-3S For an alarm list element, the property settings, bit memory table, and characterstring memory table (string table) are related to each other as shown below.Alarm listDisplayedat ONCharacter string memorytable (String table):10ABCCharacter stringmemory table(String table)Bit memory tableImage/library dataPC (PLC) address:FE20:000100010ABC11DEF12GHI13JKLImage dataFE20Specified PC(PLC) bitNumber of bits; Set for “No.
