Characteristic curve

Characteristic curve
The characteristic curves of devices are displayed here if it has been set to "free (user-defined)".
If tight closing is active, the tight closing limits are also displayed irrespective of the setting of
the characteristic curve.

Cyclic data transfer

The cyclic data transfer is used to transfer the useful data relevant for the process automation
between the class 1 master (control or automation system) and the positioner.
9.3.1

Configuration

Configuring with the GSD
Information about input and output ranges as well as the consistency of the cyclically
transferred data is defined in the GSD file that is used by the device to check the configuration
telegram and to declare it as valid if required.
The useful data to be transferred in the cyclic operation is determined during the projecting
planning. The data volume to be transferred can thus be optimized. The GSD files of all
common devices are already stored in the Siemens control systems. GSD files can be imported
later. You can download the GSD files from:
www.siemens.de/sipartps2

Configuring the useful data
The useful data made available to the control system or the controller through PROFIBUS
depends on the selected desired configuration.
Note
Configuration tool
In case of STEP 7, the configuration tool used is HW config.
