TB Transducer Block

FB 1 … FB 3

Function Block

Module of the PA sensors

For the cyclic data traffic, VEGAFLEX 81 provides the following modules:

•

AI FB1 (OUT)

–

Out value of the AI FB1 after scaling

•

AI FB2 (OUT)

–

Out value of the AI FB2 after scaling

•

AI FB3 (OUT)

–

Out value of the AI FB3 after scaling

•

Free Place

–

This module must be used if a value in the data telegram of the cyclical data traffic should not

be used (e.g. replacement of temperature and Additional Cyclic Value)

A maximum of three modules can be active. By means of the configuration software of the Profibus

master you can determine the configuration of the cyclical data telegram with these modules. The

procedure depends on the respective configuration software.

Note:

The modules are available in two versions:

•

Short for Profibus master supporting only one "Identifier Format" byte, e.g. Allen

Bradley
