Module of the PA sensors
For the cyclic data traffic, VEGABAR 55 provides the following modules:
•
AI (PA-OUT)
– PA-OUT value of the FB1 after scaling
•
Temperature
– PA-OUT value of the FB2 after scaling
•
Additional Cyclic Value
– Additional cyclical value (depending on the source)
•
Free Place
– 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 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.
Tip:
The modules are available in two versions:
•
Short for Profibus master supporting only one "Identifier Format" byte, e.g. Allen
Bradley
•
Long for Profibus master only supporting the "Identifier Format" byte, e.g. Siemens
S7-300/400
