About PROFIBUS PA

PROFIBUS PA is a widely used bi-directional digital communication protocol that enables the

implementation technologically advanced process control systems.
FLXA21 PROFIBUS PA communication type meets the specifications of PROFIBUS

PA Nutzerorganisation e.V. and is interoperable with devices from Yokogawa and other

manufacturers.
For information on other features, engineering, design, construction work, startup and

maintenance of PROFIBUS PA, refer to the PROFIBUS PA Nutzerorganisation e.V. website:

1.1

Internal Structure of FLXA21

The FLXA21 contains a structured mapping of function blocks. Each function block serves a

specific task.

Physical block

• Manages the status of FLXA21 hardware.
• Automatically informs the host of any detected faults or other problems.

Transducer block

• Converts sensor input to process values which are transferred to AI function block by

channels.

AI function blocks

•  Conditions raw data from the Transducer block.
•  Outputs conditioned process values
•  Carries out scaling, damping and square root extraction.
