11 The user has only read access to the following variables in the
F-I/O-module data block.
Variable

(Type)
PASS_ON
(BOOL)
QBAD
(BOOL)
ACK_REQ
(BOOL)
IPAR_OK
(BOOL)

Default value
OUT 2.0 1 "PASS_OUT = 1":
The F-I/O-module is passivated.
Cause of the passivation:
"F-communication error", "module error", "channel error" (see page 354).
"PASS_OUT = 0 UND QBAD = 1":
The F-I/O-module is passivated.
Cause of the passivation:
"PASS_ON = 1" was set in the safety program.
Comment:
Depending on the settings in the hardware configuration of STEP 7 the entire module or
only faulty channels are passivated.
OUT 2.1 1 "QBAD = 1":
Currently the substitute value ("0") is used for at least one channel instead of the process
value. Which channels are passivated is indicated via the QBAD_I_xx or QBAD_O_xx variables
(see below).
OUT 2.2 0 "ACK_REQ = 1":
The error that caused the passivation has been removed.
Acknowledgement for manual reintegration (ACK_REI) by the user is now possible.
Cause of the passivation:
"F-communication error", "module error", "channel error" (see page 354).
Comment:
If the error causing the passivation has been removed, and this has been recognized by
the F-system, the F-system sets "ACK_REQ = 1".
After acknowledgement by the user, the F-operating system sets "ACK_REQ = 0".
OUT 2.3 0 Reconfiguration of fail-safe DP-standard slaves.
OUT 3.0 0 Service information
OUT 4.0 bis
7.7
OUT 8.0 bis

1 "QBAD_I_xx = 1":
The input channel is passivated with number
xx.
The substitute value ("0") is used at input
"xx".
1 "QBAD_O_xx = 1":
The output channel is passivated with number
xx.
The substitute value ("0") is used at output
"xx".
Comment:
With the variables it can be detected
which channels are passivated.
The channel number xx has the value
range: 00 to 31
Example:
"QBAD_O_00 = 1" means:
Substitute value ("0") is currently output
at output channel.
