analog signal, the words Alarm High or Low will display to indicate if the High
limit or Low limit has been exceeded.
Cleared: The alarm has been acknowledged but the source is still outside of the
programmed alarm limits.
Outstanding: The alarm is set but the source has returned to its normal range.
Status
This parameter describes the current status of the source with respect to the source’s alarm
programming. There are four possible messages:
Okay: The alarm source is within the programmed limits.
High, Low: The source of the alarm is an analog signal it presently is above (high)
or below (low) the limit.
Not Okay: The source of the alarm is a digital signal (closure or bit) and is pres-
ently in a fault-condition state.
I/O Point Value
This parameter is the actual value of the alarm source as programmed on the alarm setup form.
Alarm Setup
The Alarm Setup screen is where you configure alarms. Each alarm channel has a program-
mable source of information that is used to detect an alarm condition. This source of informa-
tion can be any piece of data that has a physical address defined by the UAF (Universal Address
Format). This includes inputs, outputs, variables and other types of data. Assign a correspond-
ing name for each alarm channel. Be sure Alarm Enabled is checked.
Figure 8: Alarm Setup
A description of each programming parameter on this screen is listed below:
Alarm Enabled: This box can be used to enable or disable alarms before or after
they are setup. When this box is not checked (e.g., disabled), the alarm will not
be detected.
Source Data Point: This parameter identifies the physical location of the signal to
be monitored. It can be any valid data point in the SCADA 3000. The first 16
alarms default to the UAF locations for the 16 inputs on the motherboard. In the
dropdown box next to the heading, choose the data point category by clicking on
the down arrow. The choices are: inputs, outputs, timers, counters, bits, ladder
variables, C variables, alarms, and diagnostics. When you pick a category, a list of
all possible points in that category will appear. Click on the item you wish to use
as the alarm source, and click OK.
