With parameters do.25...do.32 each of the 8 ags (bit 0...7) from logic step 1 can be inverted separately.
With this function it is possible to set any chosen ag as non-ag. The parameter is bit-coded. According to
Fig. 7.3.18 the weighting of the ag to be inverted must be entered in do.25...do.32. If several ags shall be
inverted, the sum is to be formed.
7.3.22Selectionofags(do.33...do.40)
In the second logic step a selection of the ags of the rst logic step can be made. The selection is done for
each output separately, where one can choose between none and up to all 8 ags.The value of the selected
switching conditions must be entered in do.33...do.40 in accordance with g. 7.3.18. The sum is to be formed
if several ags shall be selected.
7.3.23 AND connection for outputs (do.41)
After the ags are selected for each output, now it can be determined how these are linked. As a default all
ags are OR operated, i.e. if one of the selected ags is set, the output switches.Another possibility is the AND
operation which can be adjusted with do.41. AND operation means, all selected ags must be set before the
output switches.
