BYTE 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.
