OSx feature that allows an operator to interact with the process. When a

pre-defined process event is triggered, an action request informs the

operator and requests a response. Action request icons appear at the lower

right of the screen.

client.

Collection of alarm tags grouped according to device, physical location, or

other common characteristic. When an alarm occurs in the OSx system, the

group associated with that alarm is activated, and the system notifies the

OSx station of the alarm condition. Alarm groups allow an operator to

acknowledge alarms collectively rather than tag by tag.

Parameter in the Event Preferences dialog box that determines how often

OSx updates alarm summaries and alarm group displays.

OSx function that allows the controller to monitor process variables for limit

violations or device failures. The monitored results are placed in the status

attribute of the process I/O tag. If the process I/O tag is configured for

alarming, OSx will log and display the alarm condition.

example) by another physical variable (such as the height of a column of

mercury).

A historical or real-time plot of continuous (as opposed to digital) data

points.
