7.3 Modular PROFIsafe I/O interface

7.3 Modular PROFIsafe I/O interface
Using this function, it is easier for machinery manufacturers to connect PROFIsafe
input and output modules for machine series with a modular design.
Example
The S7 configuration required for PROFIsafe communication, the appropriate NCK
machine data parameterization as well as the SPL programs for NCK and PLC are
in the control for the maximum expansion stage. Depending on the functionality
available in a real machine, then either the maximum number of PROFIsafe
modules are connected -- or just a subset of the possible PROFIsafe modules
The PROFIsafe connection and the SPL connection for the particular PROFIsafe
module are then activated while the machine is being commissioned by activating
the associated machine data set or slots. Activation is realized by setting one of
the activation bits assigned to the particular machine data set.
Activation
The "modular PROFIsafe I/O interface" function is activated using machine data
10095 $MN_SAFE_MODE_MASK, bit 1 = 1.
The Step7 hardware configuration in the PLC must be available in the full scope.

PROFIsafe input modules

Activating a machine data set or slot
The activation of a machine data set for the PROFIsafe communication and SPL
coupling of an PROFIsafe input module is realized via:
MD13302 $MN_PROFISAFE_IN_ENABLE_MASK[m]. Bit x=1.
The machine data set of a slot includes the machine data:
S $MN_PROFISAFE_IN_ADDRESS[n]
S $MN_PROFISAFE_IN_FILTER[n]
S $MN_PROFISAFE_IN_ASSIGN[n]
S $MN_PROFISAFE_IN_SUBS_ENAB_MASK[n] (see substitute values)
S $MN_PROFISAFE_IN_SUBS[n] (see substitute values)
S $MN_PROFISAFE_IN_NAME[n]
