Accessing data via PROFIBUS
Data can be accessed via PROFIBUS both cyclically and non-cyclically (see chapter 4.3).
Cyclic data is known as a process image. It is made up of data sent by the PROFIBUS master to
the drive controller and from the drive controller to the PROFIBUS master.
The cyclic data sent from the PROFIBUS master to the drive controller is known as
"Process data In".
The cyclic data sent from the drive controller to the PROFIBUS master is known as
"Process data Out".
4.1
Cyclic data access – Process data Out
4.1.1
Structure of Process data Out
The process data named below is sent from the drive controller to the PROFIBUS master.
The data is made up of 10 process variables.
IMPORTANT INFORMATION
Thanks to a corresponding selection, the INVEOR also makes it possible for you to work with a
process image of only 4 process variables. To this purpose, the master from the GSD file must
select the "INVEOR I/O small" module.
