The SxW template project offers support for audible alarms. You can configure a project so that a selected wav file is sounded whenever an alarm of a particular priority is triggered. You can even assign different sounds to different alarm priorities, allowing the urgency of an alarm to be determined from its sound.

LOSS OF CONTROL

  • Do not use Plant SCADA's alarming system as the primary alert mechanism for safety-related alarms or notifications (that is, those classified as critical to process safety, the protection of the plant and equipment, or the protection of human life).

  • Do not use Plant SCADA's audible alarm functionality as a replacement for safety-related warning systems critical to process safety, the protection of the plant and equipment or the protection of human life.

  • Safety-related alarms and notifications should be independent and separate from the process control system. They should be implemented in the form of a stand-alone physical alarm system driving individual discrete alarm annunciators.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

To implement audible alarms in your project:

Verify that the alarms you want to trigger an audible alert are assigned to a category and given a particular priority.

  1. Adjust the parameter [Alarm]Sound<n>. This parameter determines the wav file used when an alarm sounds, based on the priority of the alarm (n). For example, [Alarm]Sound1 identifies the .wav file that will be sounded whenever a priority 1 alarm is triggered.

  2. If necessary, adjust the parameter [Alarm]Sound<n>Interval. This parameter determines how long the selected wav file sounds, based on the priority of the alarm (n). For example, [Alarm]Sound1Interval sets the length of time a priority 1 alarm is sounded for.

  3. Verify that your users have appropriate privileges associated with their login to silence alarms, otherwise they will not be able to silence an alarm. See Creating a Privileged User and the parameter [Privilege]SilenceAlarms.
