Description
Parameter block type identification
1: The parameter block of the F-Parameters contains the F_iPar_CRC parameter.
Version number of the F-Parameter block.
1: Valid for V2 mode
CRC checksum via the iParameters
The value must be greater than 0.
When verifying the safety function, check whether the F_iPar_CRC parameter is
greater than 0 for all devices. If not, check the iParameters and the CRC checksum
in the iParameter and F-Parameter.
B 2
iParameters
The iParameters are individual device parameters. These include:
–
PST_Device_ID (30hex for IC220SDL840)
–
F_Destination_Address (not included in the checksum calculation)
The device parameters are verified with a checksum: iPar_CRC.
This address is the PROFIsafe address of the module. Make sure that it matches the
switch position of the 10-pos. DIP switch.
