3 Parameter definition / CRC calculation
It is best to define the known parameters before configuration in the F-Host, so that
they can be taken into account during configuration.
The procedure, in conjunction with the SIEMENS configuration software
TIA
Portal V13
and the optional package
S7 Safety Advanced V13,
is described
below.
The
TR_iParameter
software required for the CRC calculation can be downloaded
in chap.: 7 "Download of Software, Examples and Libraries" on page 159.
3.1 iParameters
The iParameters are already preconfigured with meaningful values in the default-
setting and should only be changed if expressly requested by the automation function.
A CRC calculation is necessary for safe transmission of the individually set
iParameters. This must be performed when changing the preset iParameters via the
TR program "TR_iParameter". The calculated checksum corresponds to the F-
Parameter
F_iPar_CRC
. This must be entered in the field
F_iPar_CRC
during
configuration of the measuring system. The field
F_iPar_CRC
can be found in the
device view
in the inspector window under
Properties -> General ->
PROFIsafe
, also see chapter "Setting the iParameters" on page 109.
