Variant 1: User Acknowledgement via "OA_Req"

9.3.1
For safe PLCs that offer access to the "OA_Req" bit in the PROFIsafe control
byte, the "OA_Req" bit can be used by the safe PLC. The acknowledgement
request from the error is signaled by the PROFIsafe status display element to the
PROFIsafe I/O module. The "OA_Req" bit can be used to reset passivations
caused by PROFIsafe communication errors or other errors. The "F_Ack" bit in
the output process data should not be used for this variant and should be set to 0
by the safe application. This variant is not supported by all PROFIsafe I/O
modules. The figure below provides a schematic representation of this variant for
user acknowledgement.
