To adjust the setting of this bit memory table,please refer to “Data Conversion (Bit memory conversion)”in Appendix A.179AlarmSection 6-3S The [Settings] of an alarm list element are used to specify the range of bitmemory tables which are subject to the check.The check objective range is determined by setting the start bit memory tablenumber and the number of bit memory tables. The maximum allowable numberof bit memory tables varies according to the PT model and the setting of the number of bit memory tables. The range of bit memory table numbers is displayed inparentheses in the dialog box: set the start memory table number and the number of memory tables so that the displayed range is not exceeded.While an alarm list element is displayed, the status of the bit memory tables in thespecified range is always checked and the element displays the message orimage/library data which is set for the bit memory table when a bit memory tableis turned ON.Allocation of a PC (PLC) bit to a bit memory table is specified at the bitmemory table.
(Specified character string memory table (string table)and image/library data code are also specified at the bit memory table.)Bit memory tablePC (PLC)No.0123Alarmrange128129The alarm range, i.e., the start address (No.) in the bit memorytable and the size, is specified by the alarm list element.180Alarm6-3-2Section 6-3Alarm HistoryIf a bit memory table for which a check mark is set for the history property goes ON,the date/time and the number of going ON events are recorded in an alarm history.An alarm history element displays the recorded bit table numbers in the order ofoccurrence or frequency when the element is displayed.An alarm history element can also display the contents (alarm message) of thecharacter string memory table (string table) and the image/library data which areallocated to the bit memory table.Bit memory tableScreenWARNING HIGH TEMP.Character string memorytable (string table)98/04/10 16:02No.1AlarmhistoryWARNING HIGH TEMP.No.2Image/library dataAlarm history record dataWARNING HIGH TEMP.98/04/10 16:02WARNING HIGH PRESS.
98/05/12 18:25(1) When a bit memory table for which a check mark is set for the history propertygoes ON, the alarm history element reads out the alarm message from thecharacter string memory table (string table) and records the message with thedate/time of the occurrence. The recorded information is displayed when thealarm history element is displayed.(2) If the operator touches the displayed alarm message, the specified image/library data is displayed.NoteThe bit memory tables to be checked are determined according to the settingsmade at the individual bit memory tables.Operation procedureSelection using the menu bar:[Objects] → [Alarm] → [History]Selection using the drawing toolbar:Related elements and settingsBit memory table:[Tools] → [Table] → Bit Memory(Refer to 7-4 “Bit Memory Tables”.)181AlarmSection 6-3TerminologyFrameMessageBackgroundImage/library dataDisplay lineForegroundPage scroll touch switchLengthBackgroundLine scroll touch switchProperty setting[General]Position:Indicates the display position of the alarm history.(The attribute point is at the upper left corner of the alarm history)Size:Indicates the size of the alarm history.MessageLength:Specify the number of characters of a message to be displayed.Max.

If a check mark is set for this item, the date/time of alarm occurrence is displayed with an alarm message in the case of “order of occurrence”, or the frequency of occurrence is displayed with an alarmmessage in the case of “frequency of occurrence”. The display format of thedate/time of occurrence is set for [Info Type]. If the date/time or frequency of occurrence is displayed, the number of alarm message display characters is reduced accordingly.Order TypeOrder of Frequency:Alarm messages are displayed in the order ofoccurrence frequency.Order of Occurrence:Alarm messages are displayed in the order ofoccurrence (from the oldest record or from the newestrecord). The order in which the alarm messages aredisplayed depends on the system memory setting.183AlarmSection 6-3Info Type:If the setting is so made to display the date/time of alarm occurrence, the displayformat of the date/time is specified for this item.
The setting for this item is invalidif the date/time is not displayed with an alarm message.Y/M/D h:m (14 digits)M/D h:m (11 digits)h:m (5 digits)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 check box for the linescroll touch switch and/or a page scroll touch switch in the Property setting dialogbox.S 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. To move a line scroll touch switch or a page scroll touch switch, click thedesired touch switch while holding down the Shift key and Ctrl key. ([Edit Object]from [Edit] menu (or pop–up menu) and Ins key 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.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.(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 data184AlarmSection 6-3Reference: 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.S For an alarm history element, the property settings, bit memory table, and character string memory table (string table) are related to each other as shown below.History dataH0001512 97/02/12 10:51Displayedat ONAlarm listABC02/12Character stringmemory table(String table)Bit memory tableCharacter string memorytable (String table):1010ABCImage/library data:FE2011DEFPC (PLC) address:H000151212GHI13JKLImage dataFE20Specified PC(PLC) bitNumber of bits; Set for “No.
