Differences Between

Configuration and

Calibration

Definition of Calibration

Calibration is the process of adjusting certain device parameters in order that

the physical quantities measured meet an established standard for accuracy.

Calibration Parameters in the Transducer Block

Transducer Blocks are used to configure devices. Transducer Blocks decouple

Function Blocks from the local input/output functions required to read

sensors and command output hardware. They contain information such as

calibration data and sensor type. Calibration parameters are located in the

Transducer Function Block because the Transducer Function Block is the

interface between the physical measuring unit (I/O Subsystem) and the other

function blocks.

Definition of Configuration?

Configuration is the process of setting parameters in function blocks so that

information processed from the I/O Subsystem in the Transducer Block is

made available to other function blocks.
