5.6.1.2 F_SIL
F_SIL specifies the SIL which the user expects from the respective F-Device. This is
compared with the locally saved manufacturer's specification. The measuring system
support the safety classes no SIL and SIL1 to SIL3, SIL3 = standard value.
5.6.1.3 F_CRC_Length
The measuring system supports the CRC length of 3 bytes. This value is predefined
and cannot be changed.
5.6.1.4 F_Block_ID
As the measuring system supports device-specific safety parameters such as e.g.
"Integration time Safe", this parameter is preconfigured with the value "1 = generate
F_iPar_CRC" and cannot be changed.
5.6.1.5 F_Par_Version
The parameter identifies the PROFIsafe version "V2-Mode" implemented in the
measuring system. This value is predefined and cannot be changed.
5.6.1.6 F_Source_Add / F_Dest_Add
The parameter
F_Source_Add
defines a unique source address within a PROFIsafe
cluster. The parameter
F_Dest_Add
defines a unique destination address within a
PROFIsafe cluster.
The PROFIsafe destination address must correspond to the address deposited in the
measuring system, also see page 24.
Valid addresses: 1…99.
Standard value
F_Source_Add
= 1, Standard value
F_Dest_Add
= 1,
F_Source_Add
≠
F_Dest_Add
.
5.6.1.7 F_WD_Time
This parameter defines the monitoring time [ms] in the measuring system. A valid
current safety telegram must arrive from the F-Host within this time, otherwise the
measuring system will be set to safe status.
The predefined value is 125 ms.
The watchdog time must generally be set at a level where telegram runtimes are
tolerated by the communication, but it must also allow quick execution of the error
reaction function in case of error.
5.6.1.8 F_iPar_CRC
This parameter represents the checksum value (CRC3), which is calculated from all
iParameters of the device-specific part of the measuring system and ensures safe
transmission of the iParameters. The calculation occurs in a program called
"TR_iParameter" provided by TR-Electronic. The checksum value calculated there
must then be manually entered in the F-Host engineering tool, also see chapter
"Parameter Definition / CRC Calculation" on page 45.
5.6.1.9 F_Par_CRC
This parameter represents the checksum value (CRC1), which is calculated from all
F-Parameters of the measuring system and ensures safe transmission of the
F-Parameters. The calculation occurs externally in the F-Host engineering tool and
must then be entered here under this parameter, or is generated automatically.
