Deviation Usually, the difference between set point and process variable. More

generally, any departure from a desired or expected value or pattern.

Deviation Alarm

An alarm that signals a specified amount of difference exists between two

monitored values; usually the process variable and the set point.

DI Acronym: Discrete Input

Diagnostics One or more programs in a computer or microprocessor that can detect

and pinpoint a configuration error or a hardware fault. Also, the utility or

functionality such programs add to a product.

Digital to Analog Converter (DAC or D/A)

A component or device that converts digital data or a digital signal into

an analog voltage of corresponding value.

DIO Acronym: Discrete Input/Output

Direct Acting Control action in which the absolute value of the output signal increases

as the absolute value of the input signal (process variable) increases.

Direct Control Point (DCP)

The collection of set point, process variable, and valve position values

along with tuning parameters for a control loop.

Direct Digital Control Mode (DDC)

A loop control mode: a processĆcontrol computer or a computer

program, a unit point, or a logic control point directly sets the output of a

point.

Discrete Having either of two states, for example, on or off, or 1 or 0.

Discrete Control Device (DCD)

A PROVOX point type. A DCD point combines as many as 8 discrete

output and 16 discrete input channels into a single point.

Discrete Input (DI)

A PROVOX point type. A DI point monitors a single discrete value, which

is referred to as the process variable.

Discrete Input/Output (DIO)

The reception and transmission of discrete signals. In PROVOX systems,

DIO usually refers to a discrete input/output card.

Discrete Monitor (DM)

A PROVOX point type. A DM point reads 16 discrete input channel

values, then consolidates these values into either a 16Ćbit binary value or

a 4Ćbit binaryĆcoded decimal value.
