20.12.1.1 Alarm Guide

You can set the block, display mode, and the number of Alarm Histories stored for Alarm Message (History).

Block Settings

Set the display mode and the number of Alarm History records (the number of Alarm Histories stored in the display unit) in each mode for each block.

Block

A group of Alarm Messages to be registered. A maximum of 8 blocks can be used.

Display mode

Choose the Alarm Message display method from [History], [Log], or [Active]. Choose [Active] to display only alarms which are currently triggered. To display old alarms as well, choose [History] or [Log].

Displays Alarm Messages, data, trigger date, and time, in the order they are triggered. The time when the Alarm is acknowledged or recovered will be added to the same row. The change in the state of each Alarm can be viewed on a single row.

The messages, date/time, and read data are displayed in separate rows every time the state changes from [Trigger], [Acknowledged], to [Recovery]. The date can be viewed in every state.

Only [Trigger] alarms are displayed. When an alarm recovers, it is automatically erased.

Usage

Select the [Display Mode] to be used. A total of 8 display modes at maximum can be set for the whole Alarm History.

Records

Set the number of Alarm Histories stored for each display mode. When triggered alarms exceed the specified number, the oldest alarm is deleted.

This number varies depending on the display unit model and the [Alarm Type] setting.

*1When using the SP5000 Series Open Box, you can record the same number of records as the IPC Series by selecting [Folder] in [System Settings] - [Display Unit] - [WinGP] - [Historical Data Retentive Settings] - [Save in].

Print Format

Select whether or not to print the Alarm History.

20.13.2 Restrictions for Printing Alarm History

Real-time Print/Batch Print

Choose the printing timing from [Real-time Print] or [Batch Print].

Alarm history is printed every time an alarm is [Triggered], [Acknowledged], and [Recovery].

The print format is the same as the display format of [Log].

Even when two or more blocks are used, printing is performed as occasion arises regardless of the block.

When the bit 0 in [Print Word Address] is turned ON, the whole Alarm Histories stored in the designated block are printed.

The print format is determined by the [Display Mode] settings.

The settings are checked in the order of [History], [Log], [Active], and data is printed in the format of the first [Display Mode] set [On].

For example, when printing block 1

In this case, the block is printed using [History] format. If [History] were not set, the data would be printed using [Log] format. A page feed occurs after printing.

Multiple Line Message Printing

Specify whether to print alarm messages on lines separate from other information when printing. Since the message display area expands, you can quickly verify contents of long messages. You can print a maximum of 6 lines (one line for date/time + 5 lines of message) for one alarm. The number of lines depends on the message being registered.

  • If a message is more than five lines and uses text table, the message from the sixth line onward will not be printed.

Print Word Address

This address controls the printing of the Alarm History. After setting the type of alarm, turn ON the trigger bit (bit 0) to start printing.

Completion Bit Address

Set the bit address that will tell you when printing has completed. This bit will turn ON when printing finishes.

  • After the [Completion Bit] has been confirmed as ON, please turn it OFF again. It is recommended to turn OFF the bit 0 of [Print Word Address] also at this time.

Print Format

Displays the [Print Format Settings] dialog box.

Left Margin

Select the spacing between the character of the left-most item and the border from 0 to 100 characters.

Message Spacing

You can define this when [Alarm Parts]-[Basic]-[Message Display Method]-[Multiple line display] is selected. The maximum number of characters that can display on one line is 160 characters. The number of characters in the message that can display on one line is 160 characters minus the total of [Display Characters] and [Left Margin]. Set [Display Characters] from 0 to 20.

Select blocks to print

From [Date], [Trigger], [Message], [Acknowledged], [Recovery], [Occurrences], [Elapsed Time], [Level], and [Address 1] to [Address 8], specify items to print.

  • Date

Prints the date when the alarm was triggered.

  • Trigger

Prints the time when the alarm was triggered.

  • Message

Prints Alarm Message.

  • When [Alarm Parts]-[Basic]-[Message Display Method]-[Multiple line display] is selected, messages are always displayed and you cannot clear the check box.

  • Acknowledge

Prints the time when the alarm message was confirmed.

  • Recovery

Prints alarm's recovery time.

  • Occurrences

Prints the number of times the alarm was triggered. The maximum count is 65535.

  • Elapsed Time

Prints the total duration of time when the alarm was in the triggered state. The maximum duration is 9999 hours 59 minutes 59 seconds.

  • Level

Prints the alarm's importance level.

  • Address1 - Address8

Prints data that is retrieved when the alarm is triggered, acknowledged, or recovered.

Display Characters

Set the number of characters displayed for each item. Each item's setting range is as follows.

Date

5 to 100 or 8 to 100 single-byte characters

(The setting range differs depending on the selected date format)

Trigger, Acknowledged, Recovery

5 to 100 or 8 to 100 single-byte characters

(The setting range differs depending on the selected time format)

Message

1 to 160 single-byte characters

(up to 192 characters when [Alarm Type] is set to [Extended])

Occurrences, Elapsed Time, Level

2 to 100 single-byte characters

Addresses 1 to 8

0 to 100 single-byte characters

  • When you want to provide spaces between the items, set [Total Display Digits] larger than the number of characters that will actually be displayed.

Display Order

Set the display order of all items. Blocks starting from the top of this list will be printed from left to right.

Date Format

Choose a print format for the date from [yy/mm/dd], [mm/dd/yy], [dd/mm/yy], and [mm/dd].

Time Format

Choose a print format for the time from [12:00], [24:00], [12:00:00] or [24:00:00].

Font

Choose a font type for the Alarm Message from [Standard Font] or [Stroke Font].

Triggered Color/Acknowledged Color/Recovered Color

Choose from 8 colors for the Alarm Message's [Trigger], [Acknowledged], and [Recovery] colors. Messages are printed in the specified colors regardless of the display unit type.

  • When white is selected, messages are printed in black.

  • When the [Display Mode] is [History] and [Batch Print] is set, the trigger color will be used when printing a triggered alarm, the acknowledge color for an acknowledged alarm, and the recovery color for a recovered alarm. However, when acknowledging a previously recovered alarm, the recovery color will be used for printing. The color setting is effective for text only. The background color will not be printed.

CSV Settings

Set the format to save in CSV format.

Multiple Line Message Output (Save Alarm to CSV)

Specify whether to print alarm messages on lines separate from other information. Since the message display area expands, you can quickly verify contents of long messages. A maximum of five lines for one alarm message can be printed. The number of lines depends on the message being registered.

  • If a message is more than five lines and uses text table, the message from the sixth line onward will not be printed.

Date Format

Select the [CSV Date Format] from [yy/mm/dd], [dd/mm/yy], [mm/dd/yy], [20yy/mm/dd], [dd/mm/20yy], [mm/dd/20yy], or [mm/dd]. "yy" displays the last two digits of the year, and "mm" and "dd" use two digits to display the month and date.

  • To read log data from the CF card using Pro-Server EX (upload GP log data and read as Excel report), select [yy/mm/dd]. If you select an option other than [yy/mm/dd], the date may be read incorrectly.

  • When using the MES action's Get CF Alarm History File in Pro-Server EX before V1.32, select [yy/mm/dd]. If you select an option other than [yy/mm/dd], either an error will occur or the incorrect date is saved in the database.

Backup Alarm History

Define whether or not to save Alarm History to the display unit's backup memory (SRAM).
2.3 About the Display Unit's Internal Data

When backup is not selected and the display unit is turned OFF, all the Alarm Histories displayed before are erased. When the display unit is turned ON again, only the alarms triggered at the time and afterward are displayed.

Alarm Continuous Action at Power ON

If the value of device/PLC in the [Trigger Condition] remains the same before and after the device/PLC is turned off/on, the system uses this setting for displaying the alarm.

When you restart the display unit, the status of all previous alarms change to "recovered", except for the active alarms. The active alarms are shown as newly triggered alarms.

However, if you have specified any of the following settings, the previous alarms remain on the screen after the restart. This is true, even if the value of device/PLC specified in the [Trigger Condition] stays zero or if you have selected [Display as New Alarms].

All previous alarms remains on the screen after the Display Unit is restarted.

Behaviors of Back-up Function (when [Trigger Condition] is ON)

Storage Frequency

When using GP-4100 series (excluding GP-411*T3), set up the frequency for saving alarm history data to virtual backup memory from 1 to 60 minutes.

When the defined frequency elapses, if there are no data changes from the previous save, the storage operation does not take place.

You can store history data up to 200,000 times.

LOSS OF DATA

  • Do not turn off the display unit while saving the History Data in the virtual backup memory. It may cause the loss of data or damage to the virtual backup memory.
    Before turning the display unit off, turn ON the #H_Control_StopAlarmSave system variable and then save history data. The system variable #H_Status_AlarmSave turns ON after the history data save is completed. Confirm the system variable #H_Status_AlarmSave is turned OFF and then turn off the display unit.
    When you turn ON the system variable #H_Control_StopAlarmSave before turning off the display unit, the history data is saved. Thus, data will not be saved until the next time the bit is turned OFF even if the cycle set in the [Storage Frequency] elapses.
    For more information about system variables, please see the following.
    A.2.2.1 Bit Type - #H System Variables

  • Please save history data before going to offline mode.
    If you enter offline mode before saving, reset will cause the loss of all the latest history data.
    1.5.6.2 GP-4100 Series

Failure to follow these instructions can result in equipment damage.

External Operation

Select whether or not to perform [Ack All], [Clear All], [Clear All Number of Occurrences], and [Clear All Accumulated Time] from the host (PLC).

20.14 How to Run External Operations from Multiple Display Units

Control Word Address

Set the address which will control the type of operation performed from the PLC (operation code), and the type of alarm.

When an external operation is performed, it handles all Alarm Messages in the block (active, history, log). For example, if you perform a [Clear All] on block 1, all Alarm Messages in block 1 (active, history, log) are cleared. Within a block, Active, History, and Log cannot be operated individually.

The operation's order is [History], [Log], [Active].

  • After the operation, please set the operation code to [0]. Otherwise, you cannot start a new operation.

  • Design the system such that the [Control Address] and [Completion Bit Address] are set to zero at the startup. This is a precaution for when the display unit is turned OFF during operation.

Completion Bit Address

Set the address which will monitor the completion of the operation. This bit will turn ON when the operation finishes.

  • When you set the operation code to "0", the completion bit address turns OFF automatically.

Enable Groups

Select whether or not to use the Group feature. Set this feature to count the number of times that alarms have been triggered by group number.

Number of Alarms Start Address (Internal Device Word Address)

(A)

Set the start address in the display unit's internal device to write the number of alarm occurrences.

(B)

Among the addresses set up in (A), only those with the registered group number are used as the area for the writing frequency of internal device addresses.

(C)

Each time an alarm occurs, data in the corresponding group number's address (internal device) will be increased by 1.

  • The alarm occurrence counts from 0 to 65535.

  • The largest group number available is 6096. Hence, you can specify a different group number for every alarm message.

  • Please ensure that the number of groups is within the internal device's area (USR area or LS area). For the LS area, refer to the following.
    A.1.1 LS Area (Direct Access Method Area)

  • The alarm frequency gets erased when the display unit is turned OFF. When backing up the data, please use the internal device's backup feature.
    5.4.4.3 Display Unit [Mode] - Backup Internal Device

  • When data is written to an internal device which stores alarm frequency or the display unit's power turns OFF, data are cleared and not counted properly.

  • The data format of the alarm frequency is fixed as Bin.

  • Alarms with group number 0 are not counted.

Save Accumulation/Count

Specify whether the accumulated time of an alarm and the number of times an alarm is triggered is saved to an external storage device when [Alarm Type] is set to [Extended].

Save in

Select the "Save in" location from [CF card], [SD Card] and [USB storage].

Save Condition

Selects a condition to begin saving from [Frequency], [Bit ON], or [Bit Change].

Set the save cycle (1 to 60 minutes).

Saves when the address specified in the Control Bit Address turns ON.

Saves when the address specified in the Control Bit Address changes (ON/OFF).

Frequency

When the [Save Condition] is set to [Frequency], set the save frequency (1 to 60 minutes).

Control Bit Address

When the [Save Condition] is set to [Bit ON] or [Bit Change], define the trigger bit address for saving.

Status Address

Specify the address where the save state will be stored.
