Acknowledging Error Messages

Once they have been corrected, errors can be acknowledged by the controller via
the PROFIsafe protocol.
8.5.1

Error Acknowledgment

The module supports channel granular passivation. Acknowledgement is
performed in accordance with the RIOforFA specifications.
The acknowledgment request for a corrected error is displayed on the F I/O
module via the safe status LED (green, flashing at 0.5 Hz); see section
"Indicators." The acknowledgement is also indicated in the F periphery database
(on the PLC) via the ACK_REQ bit.
Errors are manually acknowledged with a rising edge of the "ACK_REI" bit of the
F periphery database.
