Example alarm tag configuration for common scenarios are provided.
Example: Annunciated/Dial-out Alarm Tag
The following is an example of an alarm tag named Intrusion. This is how a typical annunciated/dial-out alarm would be configured.
To create an annunciated/dial-out alarm tag
1. In your HMI system, create a tag that you want to set up an alarm in SCADAlarm.
2. Start SCADAlarm.
3. On the Maintenance menu, click Alarms / Tag Names. The Alarm / Tag Data Point Definition dialog box appears.
4. In the Type of Connection box, click Data Server Status with <Server Name>.
5. Click New to add a new tag to SCADAlarm.
6. In the Name box, type in the name of the tag that you created in the HMI system (in this example, "Intrusion").
7. Select the Enable Alarm check box.
8. Configure all other required fields. For more information, see "Adding a Tag to the SCADAlarm Database" on page 66.
9. Enter all required items. In order to SCADAlarm to detect when a tag is in alarm, you must enter the alarm value or string into the Value when On or In alarm field. Also, make sure the Enable alarm option is selected. Select the operator Call Group that you want to notify in case of alarm.
Example: Analog "Information Only" Tag
The following is an example of an analog (information-only) tag named
TankLevel. Numeric data tags are typically used in the tag report script of an alarm tag, or as part of a data acquisition tag report script.
Note When the tag is an analog "information only" tag, the Speech file for Engineering Units voice prompt file is spoken immediately after the numeric value is spoken in a tag report script (for example, feet, GPM, and so on.)
To create an analog "information only" alarm tag
1. In your HMI system, create a tag. For example, "TankLevel." 2. Start SCADAlarm.
3. On the Maintenance menu, click Alarms / Tag Names. The Alarm / Tag Data Point Definition dialog box appears.
4. In the Type of Connection box, click Data Server Status with <Server Name>.
5. Click New to add a new tag to SCADAlarm.
6. In the Name box, type in the name of the tag that you created in the HMI system (in this example, "TankLevel").
7. Make sure that the Value When On or In Alarm box is blank. This indicates that this is an analog status-only tag.
8. Configure all other required fields. For more information, see "Adding a Tag to the SCADAlarm Database" on page 66.
Example: Discrete "Information Only" Tag
The following is an example of a discrete (information-only) tag namedP1Run. Discrete status tags are typically used in the tag report script of an alarm tag, or as part of a data acquisition tag report script.
To create an discrete "information only" alarm tag
1. In your HMI system, create a tag. For example, "P1Run."
2. Start SCADAlarm.
3. On the Maintenance menu, click Alarms / Tag Names. The Alarm / Tag Data Point Definition dialog box appears.
5. In the Name box, type in the name of the tag that you created in the HMI system (in this example, "P1Run").
6. Make sure that the Enable alarm check box is not selected.
7. In the Value When ON or In Alarm box, type the string reported by the HMI system when the point becomes in alarm.
8. In the Type of Connection list click Get data from <Server Name>. 9. Configure all other required fields. For more information, see "Adding a
Tag to the SCADAlarm Database" on page 66.
Example: Server Status Tag
Use the Data Server Status with <Server Name> data type to create a server "watchdog" tag. This can be used to monitor the status of the connection between a server and SCADAlarm. You could configure SCADAlarm to dial- out in the event that the server fails. Define one data server status tag per server.
To create a "server status" tag
1. In your HMI system, create a discrete tag with read/write capability. For example, "ServerStat". In Wonderware InTouch, you would create a "memory discrete" type tag. In Intellution, you would create a "DO" or "DR" with Output Enable capability and an Open Label of 0 and a Close Label of 1. Configure the SCADAlarm tag with a ".A_CV" field type. 2. Start SCADAlarm.
3. On the Maintenance menu, click Alarms / Tag Names. The Alarm / Tag Data Point Definition dialog box appears.
4. In the Type of Connection box, click Data Server Status with <Server Name>.
5. Click New to add a new tag to SCADAlarm.
6. In the Name box, type in the name of the tag that you created in the HMI system (in this example, "ServerStat").
7. Select the Enable Testing and Alarm check box.
8. Configure all other required fields. For more information, see "Adding a Tag to the SCADAlarm Database" on page 66.
SCADAlarm will periodically toggle this status bit to the HMI. If SCADAlarm fails to toggle the bit (HMI is down), a server status alarm will be posted at SCADAlarm.
