Connecting Sensors/Actuators
7.2 Connecting I/O via PROFIsafe
Warning
!
The PROFIsafe addresses are for unique identification of source and target of
safety–related communications.
The following applies to pure PROFIBUS–DP subnetworks:
The PROFIsafe target address must be unique network–wide* and station–wide**
(system–wide). A maximum of 1022 different PROFIsafe target addresses can be
assigned.
* A network consists of one or more subnets. "Network–wide" means across
subnet boundaries.
** "Station–wide" means for a station with HW configuration (e.g. a SINUMERIK
840D).
F parameters: F_source_address
The F–source–address is the decimal PROFIsafe address of the F master allo-
cated automatically by HW Config. The F_source_address is formed from the
"basis for PROFIsafe addresses" plus the PROFIBUS address of the PROFI-
BUS–DP interface.
Note
To clearly define the PROFIsafe communication, the PROFIsafe address of the
F master – assigned by HW Config – must be saved in the F master. To do this,
the PROFIsafe address of the F master must be converted from decimal into
hexadecimal and entered into the machine data of SINUMERIK 840D sl. Refer to
Chapter 7.2.4 "Parameterizing the F master (NCK)".
F parameters: F_target_address
The F_target_address is the decimal PROFIsafe address of the F module auto-
matically allocated by HW Config (the user can change this).
Note
In order to parameterize the PROFIsafe communication relationships, the
F master is informed, via the PROFIsafe address of the F module that this
F module is assigned to it. To do this, the PROFIsafe address must be converted
from decimal into hexadecimal and entered into the machine data of SINUMERIK
840D sl. Refer to Chapter 7.2.4 "Parameterizing the F master (NCK)".
The DIL switch setting shown corresponds to the PROFIsafe address to be set at
the DIL switch of the F module.
