above example, as soon as one input changes to OFF, the OUTPUT 3 output changes to OFF and PILOT OUTPUT
NUMBER displays the integer value 4.
The Parameters tab in the property box contains the number of outputs which may change to ON
depending on the number of inputs which are set to ON. The values of this parameter are fixed at 2, 3 or
4.
If the value of the parameter is fixed at 2, only the OUTPUT 1 and OUTPUT 2 outputs are used and may
therefore change to ON. In this case, if more than two inputs change to ON, the OUTPUT 1 and OUTPUT
2 outputs remain at ON and the OUTPUT 3 and OUTPUT 4 outputs remain fixed at OFF.
If the value of the parameter is fixed at 3, only the OUTPUT 1, OUTPUT 2 and OUTPUT 3 outputs are used
and may therefore change to ON. . In this case, if four inputs change to ON, the OUTPUT 1, OUTPUT 2 and
OUTPUT 3 outputs remain at ON and OUTPUT 4 remains fixed at OFF.
If the value of the parameter is fixed at 4, only the OUTPUT 1, OUTPUT 2, OUTPUT 3 and OUTPUT 4
outputs are used and may therefore change to ON.
All inputs which are not connected have the value OFF.
When the program is initialized, PILOT OUTPUT NUMBER is fixed at 1.
The Parameters tab contains the default check box which re-initializes PILOT OUTPUT NUMBER to 1 (and
defines the first output activated when the first input changes to 1) after a controller power failure.
Example of use:
Filling a tank with a group of four pumps operating in parallel. The operating duration of each pump is the
same.
The "number of outputs controlled" parameter is fixed at 4.
