Fig. 151: 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
PROFIsafe telegram only via E-bus and PROFINET/PROFIBUS
On account of the PROFIsafe policy, the use of PROFIsafe is permitted only via the PROFIBUS
and PROFINET fieldbuses or via a backplane bus, in this case for example the E-bus. The use of
PROFIsafe via other fieldbuses is impermissible for reasons connected with patent law. This must
be ensured through the use of the EL9930 segment end terminal.
The following Siemens AG patents 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
The following notes apply to PROFIsafe Master and PROFIsafe Slave 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.
