Configuring Alarms in Object Models

In the Models & Functions tab, you can configure alarms on the properties of object models. Alarms can be generated by the field system, or by Desigo CC (management system). For reference information, see Alarm Configuration Expander and Alarm Concept.

Field System (FS) Alarms

Field system alarms are generated at the level of the subsystem, panel or automation station. Alarm tables are used to map these field events to Desigo CC alarm classes.

Set up a Field System Alarm
  1. In System Browser, select Project > System Settings > Libraries > [... ] > [object model].
  1. Select the Models & Functions tab.
  1. In the Properties expander, select the property (for example, Alarm, Fault).
  1. In the Alarm Configuration expander, select the Valid check box.
  1. Select the Field system option.
  1. From the Alarm table reference drop-down list, select the alarm table you want to apply.
  1. Repeat steps 3 to 6 for each property as needed.
  1. Click Save .
  • The field system alarm is configured on the property. The corresponding FS check box is selected in the Properties overview.

 

Example of an alarm table. For information about how to edit or configure alarm tables see Modifying Alarm Tables.

 

 

Management Station (MS) Alarms

Management station alarms are instead defined directly in the Desigo CC management platform. This type of alarming requires an engineered project and should only be used as an exception. Wherever possible, define alarming on the automation station.

Information

Management station alarms cannot be forwarded if Desigo CC is not online.

The following alarm priorities are available:

  • Life Safety
  • Alarm
  • Supervision
  • General
  • Maintenance
  • Trouble
  • Fault
  • Status
Set up a Discrete Digital Alarm
  • You want to configure a discrete alarm on a Boolean property that has the Boolean text group assigned.
  1. In System Browser, select Project > System Settings > Libraries > [... ] > [object model].
  1. Select the Models & Functions tab.
  1. In the Properties expander, select the Boolean property on which to configure the alarm.
  1. Open the Alarm Configuration expander.
  1. Select the Valid check box to enable the Alarm Configuration fields.

Information
Discrete alert with GMSUint64 data type

For Uint64 data types, if you configure a discrete alert with a range with maximum higher upper limit (that is, specifying the Max Uint 64: 18446744073709551616), you will only see an event if the property value is 2^63 - 1 (9223372036854775807) or lower. Any higher value of the property will not trigger the alert.
