Default value
Description
Automatic
The parameter uniquely identifies the PROFIsafe source address (controller address).
The address is assigned automatically.
Automatic
PROFIsafe destination address (address of the safe module)
The address is assigned automatically. However, the value can be modified.
Make sure that the value set under F_Destination_Address is the same as the value that
you have set via the 12-pos. DIP switch.
Value range: 1 ... 1023
150
Monitoring time in the module
A valid current safety telegram must arrive from the safe controller during the monitoring
time. Otherwise the 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 ... 10000, in 1 ms increments
Unit: ms
SIL 3
Safety integrity (SIL according to IEC 61508) of the module
3-byte CRC
This parameter transmits the length of the CRC2 code to be expected in the safety tele-
gram to the safe controller.
1
Parameter block type identification
1: the parameter block of the F-Parameters contains the F_iPar_CRC parameter.
1
Version number of the F-Parameter block
1: valid for V2 mode
0
CRC checksum via the i-Parameters
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 modules. If not, check the i-Parameters and the CRC checksum in the
i-Parameter and F-Parameter.

are preset by the system and cannot be modified manu-
Safety functions up to SIL 3 can be achieved with the module. The
safety integrity level that can actually be achieved depends on the
parameterization, the structure of the sensor, and the cable instal-
