Status table

A status record is used to represent a one-bit or two-bit value indicating discrete device states. Status records are located in the status table and are configured using the status Row Edit dialog box.

A status record can also be configured for:

• Conversion of the raw telemetry value into a consistent representation of the device state.

• Digital output command processing (for example, start pump and verify command execution).

• Complex alarm and event processing on the current state.

• Historical data collection of the current value at periodic intervals and by exception.

• Recording the time in hours that the status value represents the active state (for example, on, open, start, trip) for the current and previous hour, day and month.

• Attachment to an Application Calculation Engine (ACE) routine for calculations or control.

From the Controller interface, a status record can be:

• Manually overridden with a value or re-enabled to use the telemetry/calculated value.

• Tagged to inhibit digital output commands.

• Commanded to operate the digital output.

A status record can also have its alarms inhibited or enabled.

Note: If you require a point with more than four states, you can create a multistate point.
