Fig.111: Parameters for the PROFIsafe master connection
Parameter Description
F_Check_Seq_Nr Setting (0/1) to indicate whether the sequence number of the connection should be
checked.
F_Check_iPar Setting (0/1) to indicate whether the parameterization should take place via an iPar
server.
F_SIL Selecting the required SIL level (SIL1, SIL2, SIL3, NoSIL)
F_CRC_Length Display of the CRC length
F_Block_ID always 0
F_Par_Version PROFIsafe version used (typically V2 mode)
F_Source_Add Setting the PROFIsafe source address
F_Dest_Add Setting the PROFIsafe destination address
F_WD_Time Setting the watchdog time
F_iPar_CRC i-parameter(s) for the PROFIsafe slave
F_Par_CRC Calculated CRC across all parameters
Note
PROFIsafe telegram only via E-Bus and PROFInet/PROFIbus
The use of PROFIsafe is only allowed via PROFIbus and PROFInet or via a backplane bus,
like E-Bus due to the PROFIsafe policy. The use of PROFIsafe over other fieldbuses is not
permitted for patent reasons. This must be ensured by using the segment end terminal
EL9930.
The following patents of Siemens AG are relevant according to the PROFIsafe profile:
EP1267270-A2 Method for data transfer
WO00/045562-A1 Method and device for determining the reliability of data carriers
WO99/049373-A1 Shortened data message of an automation system
EP1686732 Method and system for transmitting protocol data units
EP1802019 Identification of errors in data transmission
EP1921525-A1 Method for operation of a safety-related system
EP13172092.2 Method and system for detection of errors
4.12.1 Valid PROFIsafe configurations
PROFIsafe can be used if a CX controller is used, which only has EtherCAT Terminals attached and only
exchanges date with a device via PROFIbus, for sample.
