PROFIsafe output modules

Activating a machine data set or a 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 includes machine data:
● MD $MN_PROFISAFE_OUT_ADDRESS[n]
● MD $MN_PROFISAFE_OUT_FILTER[n]
● MD $MN_PROFISAFE_OUT_ASSIGN[n]
● 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:
● 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.
● 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:
PROFISAFE_OUT_ENABLE_MASK[m], bit n
Supplementary 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 PROFIsafe 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.
