4. Accessing data via PROFINET
Data can be accessed via PROFINET 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 PROFINET master to
the drive controller and from the drive controller to the PROFINET master.
The cyclic data sent from the PROFINET master to the drive controller is known as
"Process data In".
The cyclic data sent from the drive controller to the PROFINET 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 PROFINET master.
The data is made up of 10 process variables.
IMPORTANT INFORMATION
Thanks to a corresponding selection, the DGM also makes it possible for you to work with a
process image of only 2 process variables. To do this, the "2 Word Output" module has to be
dragged & dropped from the hardware catalogue to the corresponding slot. Both process
variables involve the status word and the actual frequency.
The first two process variables (status word and actual frequency) cannot be parameterized and
are always sent. The remaining 8 process variables can be configured using parameters
6.080 to
6.087 .
The "Process data Out" available can be found in chapter 4.1.3 "Process data Out".
Use DGM pc, MMI or PROFINET master for parameterisation.
