12.26.9 Parameter output – Object type output
Options
The "Output" communication object can be set to the size "1 bit" or "1 byte". The default
setting is "1-bit". In both cases you can set which value is sent out if the function is fulfilled
("true") or not fulfill ("untrue").
12.26.10 Parameter output – Send output object
Options
The "Send output object" specifies whether a telegram is trigger on the "Output"
communication object "For a change of an input object" or only "For a change of the
output object".
The first setting ("For change of an input object") means that as soon as a telegram is
received on an input communication object, the value of the output communication object
is immediately sent out. This also happens if the output value has not changed at all.
Example OR function with 2 inputs. An input already had received an ON telegram so
that an ON telegram was also trigger on the output. If the second output now receives an
ON or OFF telegram, the output value does not change thereby. Nonetheless, an
additional telegram is sent out on the output communication object.
The second setting ("For change of the output object") means that only one telegram is
sent out on the output communication object when the value has also really changed.
Example AND function with 2 inputs. An input already had received an ON telegram that
has, however, still not trigger an ON telegram on the output. If the second output now
receives an ON telegram, the output value changes. Only now is a telegram sent out the
output communication object.
12.26.11 Parameter output – Value of the output object for logic true
Options
The "Value of the output object for logic true" is set to "1" by default. I.e. as soon as the
function is fulfill, a logical "1" is present on the output. The value that is present on the
output for fulfill logic can be set via the setting "Defined via output default value true".
Note: The output value is also set to "1" with the output object size of 1-byte for the
standard setting (output object is set to 1) and a fulfill function.
12.26.12 Parameter output – Value of the output object for logic untrue
Options
1 bit
1 byte
With each input telegram
With a change of the output object
Output is set to 1
Defined via output default value true
Output is set to 0
Defined via output default value untrue
