10 Supplement
Module of the PA sensors
For the cyclic data traffic, VEGAFLEX 61 provides the following modules:
AI (PA-OUT)
l
PA-OUT value of the FB1 after scaling
-
Additional Cyclic Value
l
Additional cyclical value (depending on the source)
-
Free Place
l
This module must be used if a value should not be used in the data telegram of the cyclical data
-
traffic (e.g. replacement of the Additional Cyclic Value)
Max. 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.
Examples of telegram configuration
In the following you will see how the modules can be combined and how the appendant data telegram
is structured.
Example 1 (standard setting) with distance value and additional cyclical value:
AI (PA-OUT)

Additional Cyclic Value
l
Byte-No.

Note:
The modules are available in two versions:
Short for Profibus master supporting only one "Identifier Format"
l
