11.4 Cyclical data traffic
The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during opera-
tion. The below block diagram below shows which data can be accessed by the PLC.

11.5 Module of the PA sensors
For the cyclic data traffic, VEGAPULS 67 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)
