Assignment: F module to the F master
F net data of an F–DI module is sub–divided into units each 32 bits. Each of these
32 bit units are known as sub–slots. This sub–division, for assigning the F–DI mod-
ule to the F master is expressed in the sub–slot address.
The machine data is used to assign the F–DI module to the F master:
S MD 10386: $MN_PROFISAFE_IN_ADDRESS[Index]
(PROFIsafe address of the F–DI module)
Input format: 0s 0x aaaa
– s: Bus segment
Range of values: 5 = DP connection on the PLC side
– x: Sub–slot address
Range of values: 0...1
x = 0 addresses the F net data signals 1...32
x = 1 addresses the F net data signals 33...64
in the PROFIsafe telegram of the F slave
– aaaa: Hexadecimal PROFIsafe address of the F module
Range of values: 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 decimal format in HW
Config but must be entered into the machine data in the hexadecimal format.
Example
Net data of the 1st sub–slot is used to supply the SPL–SGE of the F–DI module
with the PROFIsafe address: 90H
F–DI module
PROFIsafe address: 90H
Fig. 7-15
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]), it is possible and also makes sense to use the same PRO-
FIsafe and sub–slot address a multiple number of times within the machine data:
S $MN_PROFISAFE_IN_ADDRESS[0...max. Index]
possible and/or practical
