PROFISAFE_IN_ENABLE_MASK[m],

SPL assignment for passive slots

For active slots, where the F net data of the associated PROFIsafe input module is

transferred into the SPL inputs, the SPL input ranges assigned via MD $MN_PRO-

FISAFE_IN_ASSIGN must not overlap. If this rule is violated, Alarm 27204 "PRO-

FIsafe: Dual allocation MD %1[%2] -- MD %3[%4]" is displayed.

To simplify parameter assignment, this rule does not apply to passive slots, whose

SPL input range overlaps with one or several active slots. In this case, without any

feedback to the user, the substitute values of the passive slot are automatically

only transferred to the SPL inputs that are not allocated active slots.

Active slot 1, corresponding to machine data set 5, is assigned SPL input range

$MN_PROFISAFE_IN_ASSIGN[5] = 009 016

Passive slot 2, corresponding to machine data set 7, is assigned SPL input range

$MN_PROFISAFE_IN_ASSIGN[7] = 005 012

$MN_PROFISAFE_IN_SUBS[7] = 0000 00FF

SPL inputs ($A_INSE)

Figure 7-20 Overlap of SPL input ranges of an active and passive slot

If the SPL input ranges of passive slots assigned using MD10388 $MN_PROFI-

SAFE_IN_ASSIGN overlap, then Alarm 27204 "PROFIsafe: Dual allocation MD

%1[%2] -- MD %3[%4]" is displayed.
