The SmartServer has built-in alarming that allows you to see alarms in the CMS Alarms widget and to receive alarm emails. Every alarm type only shows up once in the Alarms widget for each target even if the alarm criteria has occurred more than once.
You can define custom datapoint value alarm conditions for datapoint values exceeding high and low limits as described in Editing Datapoint Value Alarm Conditions in Defining Datapoint Properties, and you can specify warning and error levels for the custom datapoint value alarm conditions. You can also set up e-mail notifications for alarms as described in Setting up Alarm Email Notifications.
This section includes of the following tasks:
Viewing Alarm Notifications
Once an alarm occurs it will show up in the Alarms widget for a specific target (device or datapoint) as shown below. You must first clear this alarm in order to see another occurrence in the Alarms widget for this same alarm type for that specific target. Even though only one entry appears in the Alarms widget, you will receive an email each time the alarm criteria is met.
For example, a datapoint has up to four alarms types: Low Warning, Low Error, High Warning, and High Error. You will only see one entry for each alarm type in the Alarms widget for a specific datapoint. However, you can see the same alarm type for multiple datapoints. You will receive an email every time an alarm criteria is met, so you can get multiple emails for any alarm type.
Datapoint alarms are defined in the Datapoint Properties widget and may also be defined in a DLA file. To disable an alarm type do not specify an alarm (leave the entry blank) in the DLA file.
Alarms are only supported for scalar datapoints; datapoints with multi-fields are not supported. If you need alarms for multi-field datapoints (e.g., SNVT_switch) then you should consider using a SmartServer internal app.
With SmartServer IoT 2.5 or higher, you can use the Active Only option on the Alarms widget to display only the active alarms. Active Only refers to alarm conditions that are still active. For example, if a high-error datapoint value alarm for a temperature datapoint is set for 100 degrees, and the current measured temperature is greater than 100 degrees, then the alarm is active. If the current measured temperature is less than 100 degrees, then the alarm is not active.
If Active Only is disabled, then the alarm will be shown in both cases. If Active Only is enabled, then the alarm will only be shown in the first case (where the current measured temperature is greater than 100 degrees), as shown in the example below.
