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
automatically calculated by the
SIMATIC Manager
is necessary for safe transmission of the
individually set F-Parameters. This checksum corresponds to the F-Parameter
F_Par_CRC
,
which is displayed as a hexadecimal value in the
Properties – DP slave
window under the
heading
Current F parameter CRC (CRC1)
when configuring the measuring system with
the hardware configurator: The value
A9C3
entered in the example below is valid for the default
setting shown here, also see chapter 8.3.2 “Setting the F-Parameters“ on page 67.
7.2.1
Non-settable F-Parameters
The F-Parameters specified below are either managed by the measuring system or by the F-
Host, and therefore cannot be manually changed:
●
F_Check_SeqNr: NoCheck
●
F_CRC_Length: 3-Byte-CRC
●
F_Block_ID: 1
●
F_Par_Version: V2-mode
●
F_Source_Add: 2002 (example value, is predefined by the F-Host)
7.2.2
Settable F-Parameters
It is assumed that the following parameters are configured with their standard values:
●
F_SIL: SIL3
●
F_Dest_Add: 503 (corresponds to the set PROFIBUS a500)
●
F_WD_Time: 125
●
F_iPar_CRC: 1132081116 (calculation by means of JHG tool JHG_iParameter)
Each parameter change gives a new
F_Par_CRC
value, which is displayed as shown above. If
a safety program is already present, it must be re-generated.
