String Alarm 5 Enabled

String Alarm 6 Enabled

Enables the alarm bit. Options are 0 (No) or 1 (Yes). The alarm bit can be enabled without the Report Alarms flag set.

In the CygNet Standard Point Scheme, the alarms correspond to the following bits and alarm calculation types:

String Alarm 1 Configurable Bit 1 String Filter
String Alarm 2 Configurable Bit 2 String Filter
String Alarm 3 Configurable Bit 3 String Filter
String Alarm 4 Configurable Bit 4 String Filter
String Alarm 5 Configurable Bit 5 String Filter
String Alarm 6 Configurable Bit 5 String Filter

Alarm Priority

String Alarm 1 Priority

String Alarm 2 Priority

String Alarm 3 Priority

String Alarm 4 Priority

String Alarm 5 Priority

String Alarm 6 Priority

Specifies the priority of the point’s alarms.

Option is 0 to 99, with 99 being the highest.

In the CygNet Standard Point Scheme (0), alarm priorities are categorized as follows:

  • 0 - 24 Low
  • 25 - 49 Medium
  • 50 - 74 High
  • 75 - 99 Critical

Report To CAS

Select to reporting point alarms to the Common Alarm Service (CAS). Options are 0 (No) or 1 (Yes). The individual alarm bits must be enabled.

0 (No)

Report To GNS

Select to report point alarms to the General Notification Service (GNS), which will send notifications when an alarm bit is set/reset. Options are 0 (No) or 1 (Yes). The individual alarm bits must be enabled.

0 (No)

GNS ID

Select the ID of the GNS record to use for the notification regarding the alarm. The record type must be "Event" or "Unspecified." Click … to select a GNS ID. See Configuring a GNS Record for information about setting up GNS IDs.

Blank

Delay Reporting

Select to delay reporting of the alarm to the CAS or to the GNS for some period of time to see if the point goes out of alarm. Options are 0 (No) or 1 (Yes). The individual alarm bits must be enabled.

0 (No)

Delay Value

Specify the amount of time to delay reporting alarms or processing notifications. The countdown begins when the alarm bit gets set. When set, that delay time governs all delay times for the point. Click … to enter the reporting delay value.

The format is as follows:

  • hh:mm:ss (for values up to 18 hours: 0-17 hours, 0-59 minutes, 0-59 seconds)
  • DD:hh:mm (for values up to 40 days: 0-39 days, 0-23 hours, 0-59 minutes)
  • Y:DDD:hh (for values up to 7 years: 0-6 years, 0-364 days, 0-23 hours)

00:00:00

(hh:mm:ss)

Enhanced Alarm Configuration

Enhanced Alarm Configuration (EAC) expands the CygNet alarm rules to allow a user to extend the conditions by which a configurable status bit is allowed to be set or prevented from being set. When a configurable bit is prevented from being set, any subsequent alarms or notifications that would have been generated are prevented as well. EAC conditions are defined as a series of logical expressions that reference real-time values of the same point or multiple other points. However, all points referenced must reside in the same Common Value Service (CVS) as the point being configured. EAC conditions may contain up to 50 individual expressions, each of which could reference a separate point. The enhanced alarm configuration is available from the PNT Editor's Alarm Settings (Analog, Digital, Enumeration, String) pages.

Click Enhanced alarm settings button (Enhanced alarm settings) to open the Enhanced Alarm Settings dialog box for creating and editing EAC conditions. See Enhanced Alarm Configuration for more information.
