A.1 Festo profile for handling and positioning (FHPP)
The SFC−DC supports the Festo handling and positioning
profile FHPP (see also chapter 1.3).
A.1.1 Supported operating modes
The operating modes differ as regards their contents and the
meaning of the cyclic I/O data and in the functions which can
be accessed in the SFC−DC.
Operating mode
Description
Record Select 31 position sets can be saved in the SFC−DC. A record contains all the para
meters which are specified for a positioning task. The record number is
transferred to the cyclic I/O data as the nominal or actual value.
Direct mode The positioning task is transferred directly in the I/O telegram. The most
important nominal values (position, speed) are thereby transferred. Supple
mentary parameters (e.g. acceleration) are defined by the parametrizing.
Tab.A/1: Overview of operating modes
Record Select
Preset operating mode when the SFC−DC is started up.
The SFC−DC has 31 records (1 ... 31) which contain all the
information necessary for a positioning task (+ record 0 =
reference travel).
The record number, which the SFC−DC is to process at the
next start, is transferred to the output data of
the master.
The input data contains the last processed record number.
The positioning task itself does not need to be active.
