Decide what type of alarm monitoring you need
FactoryTalk Alarms and Events supports two types of alarm monitoring:
„
Device-based alarm monitoring . Built-in alarm instructions, that are available in
RSLogix 5000 v. 16 or later, are programmed in a logic project and then
downloaded to a Logix5000 controller. The controller detects alarm conditions
and publishes event information, which can be displayed and logged.
„
Tag-based alarm monitoring . Software-based tag alarm and event servers
monitor controllers for alarm conditions through data servers and publish event
information, which can be displayed and logged. Tag-based alarm monitoring is
supported for Logix5000, PLC-5, and SLC 500 devices communicating through
Rockwell Automation device servers (RSLinx Enterprise), or for third-party
controllers that communicate through OPC Data Servers.
You can use a mix of both types of alarm monitoring. Choose tag-based alarm
monitoring if you do not want to change the logic in your programmable controllers.
Choose tag-based alarm monitoring, if you do not want to update the firmware in
Logix5000 controllers.
What you need
„ Decide what type of application you are building.
„ Decide what type of alarm monitoring you need.
„ Install and activate FactoryTalk software.
„ Update Logix5000 firmware to version 16 if you plan to use device-based alarm
monitoring and alarm instructions that are built into Logix5000 controllers. If you
do not plan to use device-based alarm instructions, you can skip this step and use
tag-based alarm monitoring with a Tag Alarm and Event Server instead.
