6 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
TR_iParameter
software required for the CRC calculation can be downloaded
www.tr-electronic.com/service/downloads/software.html
6.1 iParameters
The iParameters are preconfigured with meaningful values in the default setting and
should only be changed if expressly required by the automation task. A CRC
calculation is necessary for safe transmission of the individually set iParameters. This
must be performed when changing the predefined iParameters via the TR program
"TR_iParameter". The calculated checksum as decimal value corresponds to the
F-Parameter
F_iPar_CRC
. This must be entered in the field with the same name in
the F-Host when configuring the measuring system.
Procedure - CRC-calculation
Start
TR_iParameter
by means of the start file "TR_iParameter.exe", then open
the template file provided with the measuring system with the menu
Datei
-->
Vorlage öffnen...
Modify the relevant parameters if necessary, then click on the
CRC bilden
switch for the
F_iPar_CRC
calculation. The result is displayed in the field
F_iPar_CRC
as decimal value.
Each parameter change requires a new
F_iPar_CRC
calculation, which must then be
taken into account in the projection.
6.2 F-Parameters
The F-Parameters are already preconfigured with meaningful values in the default
setting and should only be changed if expressly required by the automation task. A
CRC which is usually automatically calculated by the Engineering tool is necessary for
safe transmission of the individually set F-Parameters. This checksum corresponds to
the F-Parameter
F_Par_CRC
.
Each parameter change, including
F_iPar_CRC
, also gives a new
F_Par_CRC
value.
