PROFIsafe output modules

Activating a machine data set or slot
A machine data set or slot for PROFIsafe communication and SPL interface of a
PROFIsafe output module are activated using:
MD13303 $MN_PROFISAFE_OUT_ENABLE_MASK[m], bit x = 1
The machine data set of a slot encompasses the data:
S MD $MN_PROFISAFE_OUT_ADDRESS[n]
S MD $MN_PROFISAFE_OUT_FILTER[n]
S MD $MN_PROFISAFE_OUT_ASSIGN[n]
S MD $MN_PROFISAFE_OUT_NAME[n]
Slot mode
The following slot modes are obtained as a result of the possibility of activating or
deactivating a slot:
S Active
In the control, a PROFIsafe driver is active for the slot and the SPL outputs are
output as F net data at the associated PROFIsafe output module.
S Inactive
In the control, there is no PROFIsafe driver active for the slot; the PROFIsafe
master does not address the corresponding PROFIsafe I/O module.
The following table shows the interrelationship between the machine data and the
slot mode obtained from this:
Boundary conditions
Consistency check
In order that it is ensured that a consistent parameter assignment is also available
for the maximum expansion stage, when the control boots, the complete PROFI-
safe parameter assignments are always checked. This means a check is made as
to whether each machine data set of a parameterized slot is in itself consistent and
the appropriate PROFIsafe module is configured in the loaded S7 configuration.
This especially applies to machine data sets of inactive slots.
