Parameter definition / CRC calculation
3.2.1 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_CRC_Length: 3-Byte-CRC
● F_Block_ID: 1
● F_Par_Version: 1 (V2-mode)
3.2.2 Settable F-Parameters
It is assumed that the following parameters are configured with their standard values:
● F_SIL: SIL2
● F_Source_Add: 1 (address F-Host)
● F_Dest_Add: 1 (address switch)
● F_WD_Time: 125
● F_iPar_CRC: B359B0B9 (calculation by means of TR tool TR TCI Device Tool)
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.
