About FactoryTalk Alarms and Events

Before
FactoryTalk Alarms and Events
,
FactoryTalk View
 Site Edition supported only HMI tag alarm monitoring. With
FactoryTalk Alarms and Events
, a
FactoryTalk View
 application can include the following alarm monitoring:
  • Device-based alarms, including:
    • Logix instruction-based alarms
      Alarm instructions are programmed and then downloaded into
      Studio 5000
       controllers. The controller detects alarm conditions and publishes the alarm information, which is routed to
      FactoryTalk Alarms and Events
      .
    • Logix tag-based alarms
      Logix tag-based alarms associate alarm conditions with tags for
      Studio 5000
       controllers. Logix tag-based alarms monitor tag values to determine the alarm condition, but they are not part of the logic program and do not increase the scan time for a project. Logix tag-based alarms are supported only on
      Compact GuardLogix
       5380,
      CompactLogix
       5380,
      CompactLogix
       5480,
      ControlLogix
       5580, and
      GuardLogix
       5580 controllers.
  • Server tag-based alarms
    Alarm conditions are defined and managed with software that monitors programmable controllers through tags. Tag-based alarm monitoring is supported by
    Rockwell Automation
     controllers communicating through
    Rockwell Automation
     device servers (
    FactoryTalk Linx
    ), third-party controllers communicating through OPC data servers, and HMI tags. Use server tag-based alarm monitoring if you do not want to use the pre-built instructions in Studio 5000 Logix Designer, or do not have Studio 5000 controllers.
  • OPC UA alarms
    Alarm conditions are provided by third-party OPC UA servers. The alarm data is then routed to
    FactoryTalk Alarms and Events
     through FactoryTalk Linx OPC UA Connector.
Regardless of whether alarms are detected through device-based, server tag-based, or OPC UA alarm monitoring, alarm data is provided to
FactoryTalk Alarms and Events
, which routes alarms to a central log and to graphic objects hosted in
FactoryTalk View
 graphic displays.
FactoryTalk Alarms and Events
 enables participating
FactoryTalk
 products, such as
FactoryTalk View
, to use alarm information detected from devices distributed across an application, including:
  • Studio 5000
     controllers communicating through
    Rockwell Automation
     Device Servers (
    FactoryTalk Linx
    )
  • PLC-5
     and
    SLC 500
     controllers communicating through
    RSLinx Classic
     and Tag Alarm and Event Servers
  • Third-party PLCs communicating through OPC data servers, using Tag Alarm and Event Servers.
  • Third-party PLCs communicating through OPC UA servers, using FactoryTalk Linx OPC UA Connector.
Operators interact with alarms through graphic objects, which include:
  • Alarm and Event Summary
  • Alarm Status Explorer
  • Alarm and Event Banner
  • Alarm and Event Log Viewer
FactoryTalk Alarms and Events
 services can reside on a single computer or can be distributed over a network.
