Add a device server for Logix5000, PLC-5, or SLC 500
controllers
To use device-based alarms in Logix5000 controllers, or tag-based alarms in PLC-5,
SLC 500, or Logix5000 controllers you must add a device server to your application.
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.
Before you begin
„ If you are using device-based alarms, define your alarms, as shown in Chapter 3,
“Define device-based alarms in Logix5000 controllers”.
„ If you are using tag-based alarms, you can create a controller program to detect
alarm conditions and then communicate them through tags that are monitored by
the FactoryTalk Tag Alarm and Event Server.
