Generation of the internal outputs
7.2.12.1 Parameter overview
The internal outputs (= outputs of the comparator level) can be used as source for gener-
ation of the output state.
It can be determined with do19 AND operation for output whether the flags should be
linked OR (standard) or AND (adjustable with do19).
Which flags are used to generate an internal output is parameterized via the objects
do20...do27.
Selection of the link type for output O1…OD
Selection of the flags for internal output O1
Selection of the flags for internal output O2
Selection of the flags for internal output O3
Selection of the flags for internal output O4
Selection of the flags for internal output OA
Selection of the flags for internal output OB
Selection of the flags for internal output OC
Selection of the flags for the relay
Selection of which flags are to be inverted before
linking
The selection which flags are to be inverted for the generation of the respective output
signal is made in the array do28.
The selection for output O1 is made in do28[1], for output O2 in do28[2], for output O3 in
do28[3], etc. up to do28[8] for the relay output. Not all outputs are available on all control
card types. (see also the overview in Figure 125: Comparator levelFigure 124: Digital out-
puts block diagram)
If several function blocks are se-
lected for one output, the selected
flags are OR-connected (output is
set if at least one flag is set) or
AND-connected (output is set if all
assigned flags are set).
The type of connection is defined in
do19.
