Creating or Editing Alarm Log Entries

Each Alarm log entry for the selected gas (meter or station) or liquid device Node and time period is shown on the control grid, and can be used as a vehicle for viewing, creating, or editing* alarm state configurations for selected alarm log records. Changes made to alarm log data are historized in the CygNet Measurement system when they are saved.

You must have proper security authorization to edit alarm log records. See FMS Security (and DEVALA security event) for information about configuring security access for alarm log records.

Saving Changes

When you Save changed records in the Alarm control, you access the Save Changes dialog box to generate a record of the change.

Multiple edits can be performed at one time, and will generate a single command log and audit history record when you save the edits with a single Save action. When saving edits to multiple records, either all edits will be saved successfully or, if there are errors, no edits will be saved.

To Save Changes

1. Edit the desired values.
2. Once values have been entered or changed for all desired records, click Save to write the new values and historize the changes. The Save Changes dialog box will appear.

Save Changes

1. Select an Audit category from the drop-down menu, for auditing purposes. The Audit Category selections are listed as configured on the Administrative Options page, for the category type Data Change. See Configuring Audit Categories for more information about audit categories. See Auditing in CygNet Measurement for more information about the auditing process.
2. Optionally, type Comments into the text box to explain the change. Maximum character count is 140. Although comments are optional, the comment becomes part of the audit record and can be helpful to identify the context for the change when auditing or reviewing records later.
3. Click Save to save the record change(s), or click Cancel to abandon the change(s).
