Module of the PA sensors
For the cyclic data traffic, DPT10 provides the following modules:
l AI (PA-OUT)
-
PA-OUT value of the FB1 after scaling
l Temperature
-
PA-OUT value of the FB2 after scaling
l Additional Cyclic Value
-
Additional cyclical value (depending on the source)
l 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)
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.
The modules are available in two versions:
l Short for Profibus master supporting only one "Identifier Format" byte, e.g. Allen Bradley
l Long for Profibus master only supporting the "Identifier Format" byte, e.g. Siemens S7-300/400
Examples of telegram configuration
In the following you will see how the modules can be combined and how the appendant data telegram
is structured.
