HMI tag alarm features
Using HMI tag alarms, you can:
Monitor any analog or digital HMI tag for alarms, up to a maximum of
40,000 tags per HMI server (10,000 of these can be analog tags).
Show the most recent 2,000 alarm transactions in an HMI tag alarm
Define up to eight different severity levels to distinguish alarms
Use system default messages or custom messages to describe HMI tag
Log alarm messages to a file, to a printer, or to both.
Suppress HMI tag alarms for maintenance and tuning purposes.
Associate a command or macro with an alarm to provide custom
handling of the alarm.
Share alarm information with other FactoryTalk View SE components.
For example, you can use alarm HMI tag alarm functions in
expressions in a graphic display.
Use the Acknowledge bit to synchronize alarm acknowledgment on
redundant HMI server pairs.
Use the AlarmEvent command to respond to alarm detection
algorithms you create for notification, logging, printing, and for display
in HMI tag alarm summaries.
About FactoryTalk Alarms and Events
An HMI tag alarm system only detects alarms set up for tags in an HMI
server’s tag database. HMI tag alarm detection does not include FactoryTalk
To centralize alarm monitoring and control at the FactoryTalk Directory, set
up these types of FactoryTalk alarms:
Device-based alarms, set up by programming alarm detection
instructions directly into Logix5000 controllers.
FactoryTalk View SE Clients receive device-based alarms by way of
Rockwell Automation Device Servers (RSLinx Enterprise) that you
add to a FactoryTalk View SE application.
Tag-based alarms, set up to specify alarm conditions for tags in older
programmable controllers (PLC-5 or SLC 500), in third-party devices
