Service information
-
PASS_ON
With the PASS_ON variable, you can activate a passivation of the safety option. Pas-
sivation of the F-periphery takes place, provided that PASS_ON = "1".
ACK_NEC
After resolving an error, the safety option is reintegrated depending on the setting of
the variable ACK_NEC.
•
ACK_NEC = 0: Automatic reintegration occurs.
•
ACK_NEC = 1: Automatic reintegration occurs following acknowledgment by the
user.
WARNING
Disallowed parameterization of the variable
ACK_NEC = 0
.
Severe or fatal injuries
•
The parameterization of the variable
ACK_NEC = 0
is permitted only if automatic
reintegration is safe for the process in question.
•
Check if automatic reintegration is permitted for the process in question.
ACK_REI
In order to reintegrate the safety option after the fault has been corrected, user ac-
knowledgment with positive edge at the variable
ACK_REI
is required. Acknowledg-
ment is only possible if variable
ACK_REQ = 1
.
ACK_REQ
The F control system sets
ACK_REQ = 1
after all faults in the data exchange with the
safety option have been corrected. After successful acknowledgment, the F control
system sets
ACK_REQ
to "0".
PASS_OUT
The variable
PASS_OUT
indicates whether there is a passivation of the safety option.
Substitute values are output.
QBAD
Fault in the data exchange with the safety option. Indicates passivation. Substitute val-
ues are output.
DIAG
For service information purposes, the variable
DIAG
supplies non-failsafe information
about faults that have occurred in the F control system. For further information, refer to
the relevant F control system manual.
