5.3 Acknowledgement corrected faults
5.3.1
Acknowledgement module faults
To acknowledge module faults, the F function block "F_ACK_GL" [FB219] should
be used for global acknowledgement of F_peripheral faults.
F_ACK_GL = Global acknowledgement of all F_peripheral faults of a F_runtime
group
INFORMATION
If you use the ACK_GL command, it is not necessary to program an
acknowledgement individually for each F_periphery of the F_runtime group
by using the ACK_REI variable of the corresponding F_periphery DB.
Acknowledge with "F_ACK_GL"
Module fault outgoing / can be acknowledged:
−
If there are no further module faults for the SB-PN:
−
The Err-LED of the SFB-PN flashes GREEN as acknowledgement request.
(refer to Chapter 3.3.3)
−
Diagnostic alarm "Fault outgoing" is sent to the F-PLC.
−
The acknowledgement request ACK_REQ is set internally in the
F_periphery block.
The signal ACK_REQ can be read from the F_Peripherie_DB.
−
With the input ACK_GLOB at the FB F_ACK_GL the fault can be
acknowledged and the SFB-PN is reintegrated.
−
The RED SF-LED of the SFB-PN is switched off. (refer to Chapter 3.3.3)
−
The Err-LED of the SFB-PN lights up GREEN = Module faultless / RUN.
(refer to Chapter 3.3.1)
−
If there are no further faults on the F-module, the F-PLC clears the
RED SF-LED. This depends on the type of F-PLC used.
Separate acknowledgement of individual F_peripherals
Alternatively, a separate acknowledgement can be manually programmed for each
F_periphery of the F_runtime group. The acknowledgement mechanism defined in
the PROFIsafe profile is used for this.

INFORMATION
Further information on acknowledgement via the PROFIsafe acknowledgement
mechanism can be found in the online help or in the system manual of the
engineering software.
