SPL assignment for passive slots
For
into the SPL inputs, the SPL input areas assigned via MD $MN_PROFISAFE_IN_ASSIGN
must not overlap. If this rule is violated, Alarm 27204 "PROFIsafe: Dual allocation MD %1[%2]
- MD %3[%4]" is displayed.
To simplify parameter assignment, this rule does not apply to
area overlaps with one or several
the substitute values of the
that are not allocated
Example:
Active slot 1, corresponding to machine data set 5, is assigned SPL input area 9 - 16.
$MN_PROFISAFE_IN_ASSIGN[5] = 009 016
Passive slot 2, corresponding to machine data set 7, is assigned SPL input area 5 - 12.
$MN_PROFISAFE_IN_ASSIGN[7] = 005 012
$MN_PROFISAFE_IN_SUBS[7] = 0000 00FF

If the SPL input areas of passive slots assigned using MD10388
$MN_PROFISAFE_IN_ASSIGN overlap, then Alarm 27204 "PROFIsafe: Dual allocation MD
%1[%2] - MD %3[%4]" is displayed.
