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