Restart Inhibit Ix and Ix+1 Parameter

Measures required if the Restart Inhibit parameter is set to "Deactivated"
If you have set the Restart Inhibit parameter to "Deactivated" and the F I/O
module outputs the diagnostic message "Discrepancy time exceeded," you must
ensure that all necessary repair steps are taken immediately, because
subsequent faults could be dangerous.
The Restart Inhibit parameter is used to set the reintegration behavior of the F
I/O module after a discrepancy error between the digital inputs.
The Restart Inhibit parameter is used for dual-channel pre-evaluation of two
digital inputs. Restart Inhibit is then only used by the F I/O module if the
Operating Mode parameter is set to the value "Standard" and the value of the
Pre-Evaluation parameter is set to "Equivalent" or "Antivalent."
Restart Inhibit is only evaluated if both channels of a channel pair have no
channel error.
If you have set the Restart Inhibit parameter to "Activated," then the F I/O
module behaves as follows:
A discrepancy error that has been eliminated can only be acknowledged if the
input signals have taken on the values listed in the following table.
