20.12.1.1 Alarm Settings (Common Settings)

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].

• History

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.

• Log

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.

• Active

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].

Real-time Print/Batch Print

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

• Real-time 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.

• Batch Print

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.

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.

Print Format

Displays the [Print Format Settings] dialog box.

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.

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.

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.

• Display as a new 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].

• In [Bit Monitoring], [Trigger Condition] is OFF.

• In [Word Monitoring], the Alarm Value of [Trigger Condition] is zero.

• In [Word Monitoring], the Alarm Range of [Trigger Condition] contains zero.

• Hide Continuing 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.

Date/Time Format

When the [Append Date/Time to file name] check box is selected, set up the time stamp format with 16 single-byte characters or less. You can use single-byte alphanumeric characters, the following single-byte symbols, and the following macro symbols.

• Single-byte symbols

% _ - ( )

• Macro

Preview

Based on the defined [Date/Time Format], displays an image illustrating the file name with the current date and time. When the format is invalid, the preview is not updated.

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].

Completion Bit Address

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

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.

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].

• Frequency

Set the save cycle (1 to 60 minutes).

• Bit ON

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

• Bit Change

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.

Block

Select the Alarm blocks that will send e-mail.

Receiver Groups

Specify the receiver group number configured in [System Settings] - [E-mail].

E-mail Trigger

Select the e-mail trigger from [Trigger], [Acknowledged], [Recovery], or [Save CSV]. You can select multiple options.

When [Save CSV] is selected, an Alarm History CSV file is attached to the e-mail.

Launch RemoteHMI Link
