5.5 Festo profile for handling and positioning (FHPP)
5.5.1 FHPP 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−LAC.
Operating mode Description
Record Select 31 position sets can be saved in the SFC−LAC. A record contains all
the parameters which are specified for a positioning task.
The record number is transferred to the cyclic I/O data.
Direct mode The positioning task is transferred directly in the I/O telegram.
Only the most important nominal values (position, speed) are
thereby transferred. Supplementary parameters (e.g. acceleration)
are fixed via the parametrizing.
Tab.5/2: Overview of operating modes
The operating mode is switched by the control byte CCON
(see below) and indicated in the status byte SCON. Definition
by means of parametrization is not possible. Switching
between modes is only permitted in the Drive disabled" or
Drive enabled" status.
Record select
Preset operating mode when the SFC−LAC is started up.
The SFC−LAC has 31 records (1
Ū
31) which contain all the
information necessary for a positioning task (+ record 0 =
reference travel).
The record number, which the SFC−LAC 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.
