In the FB error state, the outputs assume the safe state "0", only the Error output is "1".
The characteristics for acknowledging a discrepancy error can be set via the checkbox Safe Inputs after
Disc Error. If the checkbox is checked, both inputs of the input group that has caused the discrepancy
error have to switch to safe state simultaneously before the error can be reset.

Description
Restart
TwinSAFE-In
FB-Out
Standard-In
BOOL
During start-up (when the corresponding TwinSAFE group
is started) or a restart (when an input has requested the
safe state), a falling edge must be detected at the Restart
input before the safe state of the outputs is canceled.
EStopIn1
TwinSAFE-In
FB-Out
BOOL
1st input channel: The parameterization determines,
whether the input will be a break contact (safe state will be
requested by logical 0) or make contact (safe state will be
requested by logical 1).
EStopIn2
TwinSAFE-In
FB-Out
BOOL
2nd input channel, behaves like EStopIn1
If the discrepancy time is not equal 0, the 1st and 2nd input
channel are considered to be the 1st input pair and a
discrepancy time monitoring is carried out between both
channels.
EStopIn3
TwinSAFE-In
FB-Out
BOOL
3rd input channel or 1st input channel of the 2nd input pair,
otherwise corresponds with EStopIn1
EStopIn4
TwinSAFE-In
FB-Out
BOOL
4th input channel or 2nd input channel of the 2nd input pair,
otherwise corresponds with EStopIn2
EStopIn5
TwinSAFE-In
FB-Out
BOOL
5th input channel or 1st input channel of the 3rd input pair,
otherwise corresponds with EStopIn1
EStopIn6
TwinSAFE-In
FB-Out
BOOL
6th input channel or 2nd input channel of the 3rd input pair,
otherwise corresponds with EStopIn2
EStopIn7
TwinSAFE-In
FB-Out
BOOL
7th input channel or 1st input channel of the 4th input pair,
otherwise corresponds with EStopIn1
EStopIn8
TwinSAFE-In
FB-Out
BOOL
8th input channel or 2nd input channel of the 4th input pair,
otherwise corresponds with EStopIn2
EDM1
TwinSAFE-In
FB-Out
Standard-In
BOOL
EDM1 is the feedback loop for the non-delayed output
channel (EStopOut). If this input is parameterized as active,
the safe state of the outputs will only be exited during
restart, when the EDM1 supplies the "1" signal.
EDM2
TwinSAFE-In
FB-Out
Standard-In
BOOL
EDM2 is the feedback loop for the delayed switching of the
output channel (EStopDelOut). If this input is parameterized
as active, the safe state of the outputs will only be exited
during restart, when the EDM2 supplies the "1" signal.
