Substitute values

For all outgoing process data (F-PE), the value "0" is written as the substitute value.
One exception is Fault state. For Fault state, the value "1" is written as the substitute
value in the case of a fault-free protocol. In the case of a faulty F-protocol, the value
"0" is written for Fault state.

Possible acknowledgment procedures of the safety option

9.5.1

Acknowledging fault-free data exchange using PROFIsafe

The PROFIsafe communication must be fault-free for safe data exchange of the safety
option via PROFIsafe. As soon as there is an acknowledgment request of the safety
option via the ACK_NEC bit in the F-periphery data component, the user must trigger
an acknowledgment by a rising edge via the ACK_REI bit.
9.5.2

Acknowledging the fault

As soon as the safe data exchange of the safety option using PROFIsafe is fault-free,
faults in the safety option can be acknowledged by a rising edge with the Fault ac-
knowledgment bit in the F-process output data.
