Analog table

Analog records are used to represent a floating point value. The analog value is stored in the curval field and is often expressed as a measured value such as pressure or voltage. Analog records are located in the analog table and are configured using the analog Row Edit dialog box.

In addition, analog records can be configured for:

• Conversion of a raw telemetry value into a value in Engineering Units (EGUs).

• First order smoothing of the raw input value.

• Setpoint command processing.

• Complex alarm and event processing on the current analog value.

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

• Current value averaging for the current and previous communications statistics on the primary or alternate paths.

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

From easy eXtended Operator Station (ezXOS), an analog record can be:

• Manually overridden with a value, or enabled to use the telemetry/calculated value again.

• Tagged to inhibit setpoint commands.

• Commanded to send a new setpoint value.

An analog record can also have its alarms inhibited/enabled and its alarm limits changed.
