Defining alarm conditions for HMI tags
You can define alarms for HMI analog and digital tags.
At run time, FactoryTalk View scans the tag values in the tag database and compares them
to the limits set for these tags. If a tag value crosses a limit, an alarm is triggered.
When an HMI tag is set up with an alarm, an X is shown in the Alm column of the Tags
editor’s spreadsheet. When the tag is selected, the Alarm button in the editor’s form
becomes available.
For more information about setting up an alarm system using HMI tags, see Chapter 11,
Setting up HMI tag alarms.
Modifying HMI tag and alarm properties at run time
You can modify HMI tags and their alarm definitions in a FactoryTalk View SE network
distributed application, and have the changes take effect at connected run-time clients
without restarting the clients.
For a redundant network distributed application, you can also replicate changes made at
the primary server to the secondary server.
For more information, see “Modifying HMI tag and alarm properties at run time” on
page 14-23.
