AnalogDevice object General tab

Type

AnalogType

Used to specify whether the AnalogDevice object is a basic analog device or an analog PID regulator device. Valid values are: AnalogInput, AnalogRegulator.

Read-Only

Enable analog output

AnalogOutputEnabled

Used to allow the basic analog-type AnalogDevice object to have an output.

None

Enable PV override

PV.OverrideEnabled

Used to allow the PV mode to be set to Manual instead of the default of Auto.

Supervisory, User

Initial PV mode

PV.Mode

The initial PV mode setting, either Auto or Manual.

Supervisory, User

PV value

PV

The default "process value," in engineering units, if the initial PV mode setting is Manual.

For extra quality handling, see Attributes with extra quality handling.

Supervisory, User

Engineering units

PV.EngUnits

The name of the engineering units. For example, PSI. The maximum number of characters is 32.

User

PV deadband

Deadband

The value, in engineering units, by which the input must change to update the PVAuto value.

Supervisory, User

Enable I/O scaling

Scaled

Used to enable scaling between the raw value and the EU value.

None

Raw value - Minimum

RawMin

The raw input minimum to be used in the scaling calculation.

Supervisory, User

Raw value - Maximum

RawMax

The raw input maximum to be used in the scaling calculation.

Supervisory, User

EU value - Minimum

EngUnitsMin

The minimum value, in engineering units, used in the scaling calculation.

Supervisory, User

EU value - Maximum

EngUnitsMax

The maximum value, in engineering units, used in the scaling calculation.

Supervisory, User

EU range value - Minimum

EngUnitsRangeMin

If scaling is enabled, the lowest allowed value for PV before it is either clamped or set NaN, if clamping is enabled. This value must be less than or equal to the specified minimum engineering unit value.

Supervisory, User

EU range value - Maximum

EngUnitsRangeMax

If scaling is enabled, the highest allowed value for PV before it is either clamped or set NaN, if clamping is enabled. This value must be greater than or equal to the specified maximum engineering unit value.

Supervisory, User

Conversion mode

ConversionMode

Used to specify either Linear or Square Root for the equation that will be used to scale the input.

Read-Only

Clamp input to EU range

ClampEnabled

Used to allow the scaling process to clamp the engineering unit result. If clamping is enabled, the scaling calculation result is clamped at either the maximum engineering unit range value or the minimum engineering unit range value, and the PV quality is set to UNCERTAIN. If not clamped, and the PV exceeds the engineering unit range, then PVAuto is set to NaN, and the quality is set to BAD.
