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 summary.

Define up to eight different severity levels to distinguish alarms visually.

Use system default messages or custom messages to describe HMI tag alarms.

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 alarms.

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 communicating
through OPC data servers, or in an HMI server’s tag database (HMI tags).

FactoryTalk View SE Clients receive tag-based alarms by way of FactoryTalk Tag
Alarm and Event Servers that you add to a FactoryTalk View SE application.
