ViewPLUS SCADA Alarm Screens Application Notes
ViewPLUS Client Screen Alarm Page
The ViewPLUS Client screen alarm page consists of two parts.
The active alarm section, where active alarms are monitored, is indicated by number 1, while the alarm log section, which contains past alarms, is indicated by number 2.
Note: The information in this document is valid for ViewPLUS version 0.9.154 and later.
The alarms on the client screen can play in three different alarm sounds based on their priority level. To view the range of priority level values, open the Alarms section in the ViewPLUS channel tag editor. Select any alarm in the Alarms section and hover the mouse over the priority field to see that the information screen opens.
The priority levels for high-level alarms range from 0 to 31,
For medium-level alarms range from 32 to 63,
For low-level alarms range from 64 to 95,
For warning alarms specifically added, the priority level ranges from 96 to 127.
What sets warning alarms apart from other alarms is that when an alarm condition occurs, they do not play an alarm sound. Instead, they operate as silent alarms.
Note: If all alarm sounds are to be turned off, the "Mute Alarm Sounds" option on the client screen should be checked.
Active Alarms Section
The features in the active alarm section of the client screen are indicated by numbering them in Figure 2.
Number 1 Filter Alarms: If an alarm filter is to be used, the expression to be filtered in this section is entered.
Number 2: If an alarm filter is to be used, the feature to be filtered is selected from this section. The columns displayed on the screen are presented as filtering options here.
Number 3 Event Time: The time of occurrence of the alarm or the time when the last value of the alarm tag received by the SCADA system is written in this column if the alarm is idle.
Number 4 AlarmID: The alarm ID information in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section of the created alarm is written in this column. A different alarm ID is automatically assigned to each alarm by the ViewPLUS SCADA editor during alarm creation.
Number 5 Class: The name of the class in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section to which the created alarm is associated is written in this column.
Number 6 Name: The name of the alarm in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section to which the created alarm is associated is written in this column.
Number 7 Description: The description of the created alarm in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section to which the alarm is associated is written in this column.
Number 8 State: The current status of the created alarm is written in this column. There are two different states for created alarms, [TRG] Alarm triggered and [IDL] Alarm idle.
For example, when an alarm value is sent to the tag associated with the alarm, the alarm state of the created alarm will be [TRG] alarm triggered.
If the created alarm is not acknowledged and a value different from the alarm value is sent to the tag associated with the alarm, the alarm state will be [IDL] alarm idle. In this case, it is evaluated by ViewPLUS SCADA as if the alarm is still active. If the alarm is to be removed from the active alarms section, it must be acknowledged.
If the created alarm is acknowledged and a value different from the alarm value is sent to the tag associated with the alarm, the alarm will be removed from the active alarms section.
Number 9 Priority: The priority of the generated alarm is written in this column in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section. By applying an alarm filter based on the priority value entered here, you can list your alarms in order of priority. 255 different levels can be defined as alarm priority.
Number 10 Acknowledger: If the generated alarm has been acknowledged, the username of the person who acknowledged it is written in this column.
Number 11 Ack Message: If the generated alarm has been acknowledged, the acknowledgement message is written in this column.

Server Engine Screen Alarm Page
The alarms created via the SCADA editor can be monitored not only from the client screen but also from the server screen. The server screen alarm page consists of three tabs.
Active Alarms Section
To monitor active alarms from the server screen, go to ViewPLUS SCADA Editor -> Tools -> Start Server -> Alarms -> Active Alarms tab. The active alarms tab on the server screen has the following features, numbered in Figure 4.
Note: The features in the active alarm section of the client screen and the active alarm tab of the server screen are similar to each other. If the accuracy of the alarms created on the client screen needs to be verified, these two sections can be compared.

If the checkbox is checked when creating the alarm, the value written here will be 1, and if it is not checked, the value written here will be 0. This option allows the created alarm to be enabled or disabled.
Number 6 Ack Required: Whether the checkbox for "Ack Required" in the ViewPLUS SCADA Editor -> Tag Channel Editor -> Alarms section is checked or not is indicated in this column. If the checkbox is checked when creating the alarm, the value written here will be 1, and if it is not checked, the value written here will be 0. This option determines whether the created alarm will require user acknowledgment (acknowledge).

Number 3 Current State: The current state of the alarm is written in this column. Two different states occur for created alarms: alarm active or alarm idle. For example, when the value of the tag associated with the alarm arrives, the alarm state of the created alarm will be alarm active. If the alarm is not acknowledged and a value different from the alarm value arrives at the tag associated with the alarm, the alarm state will be alarm idle.
Number 4 Event Type: The event types of the generated alarms are written in this column.
The possible event types are as follows:
