Parameterizing the SPL-SGA interface

Note
The following examples show the parameterization of the SPL-SGA interface
based on the following specifications:
F-DO module
– F address: 256 = 100H
– F net data length: 6 bytes
Machine data
– MD10387 $MN_PROFISAFE_OUT_ADDRESS[3] = 05 01 0100
– MD13301 $MN_PROFISAFE_OUT_FILTER[3]
– MD10389 $MN_PROFISAFE_OUT_ASSIGN[3]
Assignment: F module to the F master
The F net data of an F-DO module are sub-divided into 32-bit units. Each of these
32 bit units are known as sub-slots. This sub-division, for assigning the F-DO mo-
dule to the F master is expressed in the sub-slot address.
The machine data is used to assign the F-DO module to the F master:
S MD 10387: $MN_PROFISAFE_OUT_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
– 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
SPL-SGA are written – as F net data – into the 2nd sub-slot of the F-DO module
with PROFIsafe address: 100H.
