9.3.2 Variant 2: User Acknowledgement via "OA_Req" and
"F_Ack"
For safe PLCs that offer the safe application no access to the "OA_Req", only
PROFIsafe communication errors can be acknowledged via the "OA_Req" bit in
the PROFIsafe control byte. To acknowledge other errors, the PROFIsafe I/O
module provides an acknowledgement via the "F_Ack" in the output process data.
For this variant, the acknowledgement request is only displayed for PROFIsafe
communication errors by the PROFIsafe status display element to the PROFIsafe
I/O module. For other errors, the acknowledgement request is not displayed by the
PROFIsafe status display element. The acknowledgement request for these errors
is only displayed by the group error display element (red) and channel status (red)
of the PROFIsafe I/O module.
To acknowledge both PROFIsafe communication errors and other errors with one
button, the "User Acknowledgement" signal must affect the "OA_Req" and
"F_Ack" bits. The figure below provides a schematic representation of this variant
for user acknowledgement.
