Connecting sensors and actuators
8.2 Connecting I/O via PROFIsafe
The machine data is used to assign the F-DI module to the F-master:
● MD10386 $MN_PROFISAFE_IN_ADDRESS[0...47]
(PROFIsafe address of the F-DI module)
Input format: 0s 0x aaaa
s: Bus segment
Value range: 5 = I/O connection on the PLC side
x: Sub-slot address
Value range: 0...2
x = 0 addresses the F-net data signals 1...32
x = 1 addresses the F-net data signals 33...64
x = 2 addresses the F-net data signals 65...96
in the PROFIsafe telegram from the F-slave
aaaa:
Value range: 1...FFFF
Note
The PROFIsafe address of an F-module is provided in STEP7 HW Config under:
Properties dialog box of the F-module > F-parameters: F_target_address
The PROFIsafe address of the F-module is displayed in the
must be entered into the machine data in the
Example:
User data of the 1st sub-slot is used to supply the SPL-SGE of the F-DI module with the
PROFIsafe address: 90H.
Figure 8-14
As a result of the possibility of flexibly assigning the F-net data of an F-DI module to the SPL-
SGE by combining the machine data now described (...IN_FILTER[n] and ...IN_ASSIGN[n]),
the use of the same PROFIsafe and sub-slot address a multiple number of times within the
machine data:
● $MN_PROFISAFE_IN_ADDRESS[0...max. Index]
