14.1.1 General Information
In this exercise we configure some alarms in the Controller and then show how to deal
with an alarm list in the Workplace.
14.1.1.1 Objectives
You will:
• Learn how to program alarm monitors in the controller
• Learn how to set up the OPC Connection for Alarms
• Learn how to set up the Alarm and Event Service in the Service structure in the
Aspect Integrator Platform
• Learn how to interact with alarms in the alarm list
• Learn how to copy and paste alarm lists into Excel
14.1.2 Exercise Steps
14.1.2.1 Configure an alarm for the maximum level
We want to configure a maximum level alarm for the vessel.
!
H Alarm
LH
LL
LT1
1. Right now the analogue input LT1 is configured for two events, L and H. For
the max alarm we want to use the HHH as an alarm. Please enable the HHH
for alarms at the LT1 function block (parameter AEConfigHHH).
2. Later on we want to use the default Alarm & Event List configuration in the
Process Portal. Here it is defined that a red alarm must have a severity >750.
The max level alarm for the vessel should occur as a red alarm. Because of
that please edit the AESevHHH parameter of the function block LT1.

Exercise 14.1 Alarm and Event
14.1.2.2 Setup the OPC connection for alarms
In the AC 800M/C OPC Server please create the connection to the controller
Controller_1 for Alarm and Events.
14.1.2.3 Setup the Alarm and Event service in the Process Portal
Set up the Alarm and Event server (the server where the OPC Server is running) for
the Process Portal. Please select the Service Structure of the Plant Explorer and
browse to the Alarm and Event Service. At the Basic object use the Service Group
Definition aspect for the set up.
Please set up the options in that way, that an alarm / event is displayed ones in the list,
even if several equal alarms were generated.
14.1.2.4 Insert a object description for the analogue input LT1
Right now there is no object description in the Process Portal for our objects (Some
descriptions are only available in the Control Builder).
We want to create a description for the analog input LT1 in the PP.
1. In the Control Structure please browse for the analogue input signal LT1.
2. Select the Control Builder Name aspect from LT1 and write the description
for the LT1: “Level transmitter”.
14.1.2.5 Set HHH alarm for the analogue input LT1
We want to set HHH alarm of the input LT1 by using the faceplate.
In the Control Structure please …
1. Open the Extended Faceplate for the analogue input LT1 (Main Faceplate
aspect Æ Context Menu Æ Extended Faceplate)
2. Set the HHH Alarm value to 40.0kg
3. Set the vessel level to a value more than the HHH alarm. Please take care for
the unit of the vessel which is liter (and not kg!).
14.1.2.6 Interacts with alarms in the Alarm List
Open the Alarm List aspect for the analogue input LT1 (in the Control Structure) and
…
1. Navigate to the alarm object (LT1) in the Control Builder Project Explorer
(Right click onto the alarm: Context Menu Æ select Project Explorer
aspect).
2. Navigate to the alarm object in the Control Structure (Right click onto the
alarm: Context Menu Æ select Control Structure aspect) .
3. Acknowledge the alarm (Note: You must have operator rights for
acknowledging).

4. Set the vessel input to a value less than the HHH alarm and watch the Alarm
List.
14.1.2.7 Create an Alarm List for each Tank area object
We want to create for each tank area object in the Functional Structure (Tank1 and
Tank2) an own Alarm List. This Alarm List should filter to the alarms from its child
objects.
1. In the Functional Structure please create a Alarm List for the Tank1 area
object.
2. Open the Config View for this alarm list and set the filter options. Only alarms
from this kind of objects should be included, which belong to the Tank1 area.
3. Assign a list title for the Alarm Band to the aspect. Use “Tank1” for this.
4. Repeat all this for the Tank2 area and use “Tank2” for the list title for the
Alarm Band .Will a copy/paste of the Alarm List aspect from Tank1 to Tank2
offer the needed functionality automatically?
14.1.2.8 Copy and Paste Alarm Lists into Excel
Copy and paste the alarm into Excel. Use the key combination <CTRL> + “C” and
<CTRL> + “V” for this.
