System configuration and programming > Instantiation and configuration of safety modules / definition of variable names
Parameters of safety I/O modules can be set using double-click on those modules. Each
module has two types of parameters: F-Parameters and iParameters.
F-Parameters are parameters which were specially defined by PROFIsafe group
safe device communication and parameterisation. F-Parameter names are the same for all F-
Devices (ABB and 3
F_Dest_Add, F_Source_Add, F_WD_Time and F_iPar_CRC. F_WD_Time parameter is further
used in safety function response time calculations
time" on page 317. F_Dest_Add shall be the same address as the one set on the physical
safety I/O device.
F_iPar_CRC is a special parameter which is used for a safe transfer of iParameters to F-
Devices. F_iPar_CRC is calculated outside F-Parameter editor and, thus, has to be manually
copied from "Checksum iParameter" field and pasted to F_iPar_CRC field after pressing
[Calculate] button for the given F-Device.
Note, that F_iPar_CRC has to be recalculated for AC500-S safety I/O modules also if
F_Dest_Add is changed, because F_Dest_Add is also invisibly transported as iParameter to
AC500-S safety I/O modules. It is needed in AC500-S safety PLC for further comparison of the
physical PROFIsafe address value on the safety I/O device and one configured in the engi-
neering environment.

NOTICE!
Make sure that F_Dest_Add is set unique for all F-Devices, otherwise no valid
safety configuration can be generated.
Decimal or hexadecimal number with a prefix 16# or 0x can be used to set
F_Dest_Add in Automation Builder.
