Transmitter High

A Transmitter High alarm is similar to the PV High alarm. It can be used to

indicate a failed transmitter signal.

For each alarm, you can also specify the alarm priority, sub-priority and the

specific limit. Alarm priorities and sub-priorities are described in “Defining

Events, Alarms, and Alarm Priorities” on page 162. Alarm limits are described

below.

Alarm Limit

You use the Limit field for each alarm type to specify the value (in engineering

units) at which the alarm should be generated.

Unreasonable Low and Unreasonable High Alarms for Analog Points

In addition to the previous alarm types, you can also configure a set of alarms for

an unreasonable high value and an unreasonable low value for the PV of an

analog point.

To define these alarms, you need to use Station as well as Quick Builder:

• You use Station to define the unreasonable high and unreasonable low limit

values.

• You use Quick Builder to define the alarm priority and sub-priority for

unreasonable values for each point.

Using Station

The “unreasonable high” and “unreasonable low” values are server-wide settings

that you specify on the Point Processing tab of the Alarm & Point Processing

display on a Station. See “Server-Wide Point Configuration” on page 186 for

details.

Using Quick Builder

Use the Alarm property sheet to enable unreasonable value alarms as follows:

Select an alarm priority (other than None) from the Priority list for the

Unreasonable Value field.

Specify a sub-priority for the alarm in the Sub Priority field.

Alarm priorities and sub-priorities are described in “Defining Events, Alarms, and

Alarm Priorities” on page 162.
