Overview of the PROFIsafe parameters

Several PROFIsafe parameters are available. Of these parameters, the following are
relevant for integrating the device.
• F_Dest_Add
F destination address. For PROFIsafe communication, the safety laser scanner
needs a clear F_Dest_Add. You need to enter the same value as the one config‐
ured in Safety Designer.
• F_WD_Time
Watchdog time (monitoring time) for the cyclical service. The watchdog time should
be long enough to tolerate short delays in communication. It does, however, have
an effect on the response time of the overall system (for example in the event of a
fault) and is therefore safety-relevant.
The default value is 150 ms. This is adequate in many cases. The integrator needs
to check the value and, if necessary, adjust it to avoid errors at a later time.
• F_iPar_CRC
Checksum of the safety configuration. Is used to check whether the safety-relevant
settings were changed. The entered value must match the value configured in
Safety Designer for the configuration checksum (function and network). It is only
needed if a process image is used where F_iPar_CRC is checked (module with
the suffix –iParCRC). This parameter must be updated if the configuration of the
safety laser scanner is modified in any way. If the parameter is not updated (e.g.,
due to an unauthorized modification of the configuration), the controller goes into
the safe state.
