13 F-Parameters and iParameters
13.1
F-Parameters
The values indicated in italics in
and cannot be modified manually.
F-Parameter
Default value
Description
F_Source_
Address
-
The parameter uniquely identifies the PROFIsafe source address (controller address).
The address is assigned manually.
F_Destination_
Address
-
PROFIsafe destination address (address of the safe device)
The address is assigned manually and the value can be modified.
Make sure that the value set under F_Destination_Address and the value that you have
set via the 10-pos. DIP switch are the same.
Value range: 1 ... 1022
F_WD_Time
150
Monitoring time in the safety module.
A valid current safety telegram must arrive from the safe controller within the monitoring
time. Otherwise, the safety module enters the safe state.
The selected monitoring time must be sufficiently high for telegram delays to be tolerated
by the communication, but still ensure a sufficiently fast error response in the event of an
error (e.g., interruption in communication).
Value range: 1 ... 65534, in 1 ms increments
Unit: ms
F_SIL
SIL 3
Safety integrity (SIL according to IEC 61508) of the safety module
F_CRC_Length
3-byte CRC
This parameter transmits the length of the CRC2 code to be expected in the safety tele-
gram to the safe controller.
F_Block_ID
1
Parameter block type identification
1: The parameter block of the F-Parameters contains the F_iPar_CRC parameter.
F_Par_Version
1
Version number of the F-Parameter block.
1: Valid for V2 mode
F_iPar_CRC
0
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 iParam-
eter and F-Parameter.
Table 13-1
Overview of the F-Parameters for the module
Safety functions up to SIL 3 can be achieved with the safety module. The safety integrity
level that can actually be achieved depends on the parameterization, the structure of the
sensor, and the cable installation (see
“Connection Examples for Safe Outputs” on
).
