8.3.4.6 Parameter Restart Inhibit Ix & Ix+1
Measures required if the Restart inhibit parameter is set to "no"!
If you have set the Restart inhibit parameter to "No", then if the PROFIsafe I/O
module outputs the "Discrepancy time exceeded" diagnostic message to the
secure PLC, you must independently ensure that all necessary repair measures are
implemented immediately because the following errors could be dangerous!
The Restart inhibit parameter is used to set the reintegration behavior of the
PROFIsafe I/O module after a discrepancy error between the digital inputs.
The Restart inhibit parameter is used for the dual channel evaluation of two
digital inputs. The restart inhibit is then only used by the PROFIsafe I/O module if
you have set the value of the Operating mode parameter to "Standard" and the
value of the Dual channel evaluation parameter to "yes".
You can set the Restart inhibit parameter to "Yes" or "No".
If you have set the Restart inhibit parameter to "Yes", then the PROFIsafe I/O
module behaves as follows:
A fixed discrepancy error can only be acknowledged if the input signals have
taken the values listed in the following table.

Input Pair
I1 & I2
I3 & I4
If you have set the Restart inhibit parameter to "No" acknowledgement of a
discrepancy error is successful once the deviation from the valence rule on the
digital inputs concerned no longer exists. You can set the value of the Restart
inhibit parameter for each input pair separately.
