IDX 8 Data Exchange and Alarms and Events
|Configuring a Logic alarm that analyses the state of a Heartbeat and Value/Condition alarm.|
The Snapshot alarm allows you to generate a value snapshot of one or more Alarm Event items, such as Data Exchange tags, at the time the alarm is triggered in the alarm tree. You can format the snapshot message to your requirements with custom text so that the data snapshot is presented as required in an Email or SMS message. At the time an alarm occurs, there is also the option to perform an action, which includes running a program, controlling a Windows service or writing a value into an Alarm Element such as a Data Exchange tag. We have used the service control action in a number of projects where alarms are set to monitor the health of other real-time data interfaces that happen to stop working once in a while. The Alarm action allows us to restart the interface services to get the data moving again without any user intervention.
